Introduction
The SmartTrigger by TS Engineering, Inc. is an intelligent vibratory feeder controller that is
capable of delivering a uniform level of drive voltage to the feeder coils regardless of
fluctuations in the source line. By monitoring both the amplitude and frequency of the input
line the controller can perform on-the-fly adjustments to the trigger timing of the output
alternistor and maintain the desired vibration intensity level. The unit can correct for input
line fluctuations. The standard unit without sensor is considered a voltage regulating
controller. The SmartTrigger with the sensor option is considered an amplitude regulating
control.
The four models covered in this manual (ST-1400, ST-1900, ST-2400 and ST-2900) are
functionally identical except for the on board adjustable power supply and additional filtering
circuits included in the ST-1900 and ST-2900 models. The ST-1400 and ST-2400 models
have two extra positions on TB2 (terminal block 2) to connect an external power supply.

Cable
TS ENGINEERING, INC.
External controls and connections (see figure 1)
1. AC input cable - This AC power cord supplies power to the Smart Trigger and plugs into
a standard 110 or 220 Volt AC outlet. The 110VAC versions (ST-1400 and ST-1900)
require between 95-140 Volts AC at 50/60 Hertz. The 220VAC versions (ST-2400 and
ST-2900) require 190–250 Volts AC at 50/60 Hertz.
r
USE OF AN INPUT VOLTAGE HIGHER THAN THE RATED MAXIMUM (140 VOLTS RMS FOR THE 110
UNIT AND 250 VOLTS RMS FOR THE 220 VOLT UNIT) CAN DAMAGE THE CONTROLLER AND
VOID YOUR WARRANTY!
2. Power switch - This switch turns the Smart Trigger on and off. Upon power up, there is a
0.2 second pause for internal calibration that may be followed by a soft start delay of 0.8
second depending on the setting of dip switch 3.
!
ALWAYS TURN POWER OFF BEFORE CONNECTING OR DISCONNECTING A FEEDER
OR REPLACING THE INPUT FUSE!
3. Remote wiring access hole - The Smart Trigger is delivered with this hole covered by a
metal snap-in cap. A cord grip may be installed for securing external wiring for access to the
interlocking, universal and emergency operate / hold features of the unit by switches, relays,
photo sensors, PLC’s…etc.
4. Vibration intensity (set point adjust) - This control selects the desired output power level
to adjust the vibration intensity of the feeder.
5. Power on indicator - When illuminated, this indicates that the unit is powered on.
6. Photo sensor connector (optional) – The Smart Trigger is normally delivered with this hole
covered with a plastic hole plug. A four pin threaded female connector is installed at this
location on models with a –P suffix (ST-XX00-P) and is wired for remote hold using a NPN
or PNP (active HI or LO) photo sensor. See page 31 for further information.
7. Motion sensor connector (optional) - The Smart Trigger is normally delivered with this
hole covered with a plastic hole plug. A five pin threaded female DIN connector is installed
at this location on models with a –M suffix (ST-XX00-M) to connect the Smart Trigger to a
motion sensor if required for tighter control of the output power level. See page 31 for
further information.
8. Fuse – This fast blow AC input fuse should be large enough to meet the feeder coil
requirements, but must not to exceed 15 amps maximum for any Smart Trigger model.
6
TS ENGINEERING, INC.
9. Feeder output connector - Supplies the output power to drive the feeder coils. This
variable power output is controlled by the vibration intensity (set point) adjustment. Several
different connector options are available. See page 31 for further information.
!
ONLY A FEEDER’S DRIVE COILS SHOULD BE CONNECTED TO THIS OUTLET!
10. Heatsink - Dissipates the heat generated by the electronics. It is specified for a continuous
15 Amp RMS output current in an ambient temperature environment of 45° Celsius.
AT HIGH VALUES OF CONTINUOUS LOAD CURRENT THE HEAT SINK MAY BECOME
HOT TO THE TOUCH. DO NOT BLOCK AIRFLOW AROUND THE HEATSINK DURING
!
OPERATION! THE UNIT SHOULD BE MOUNTED WITH THE HEATSINK FINS
UPRIGHT TO ALLOW FOR PROPER COOLING.

TS ENGINEERING, INC.
Motion Sensor orientation (Optional)
There are two styles of motion sensor that can be used with the Smart Trigger. Both are
interchangeable and differ in appearance only. The sensor must be mounted so that its axis of
sensitivity is parallel with the motion of the feeder. For a bowl feeder, the sensor should be
mounted near the perimeter of the bowl with the direction of the mounting screws pointing in
the direction of parts flow.

Figure 3 shows an example of a mounting strategy for bowl feeders using a right-angle
bracket mounted to the exterior of the bowl. The motion sensor MUST be mounted so that its
orientation with respect to bowl motion is the same as that shown in Figure 3, regardless of
the mounting method used.
At the other end of the motion sensor cable is a 5 pin male DIN connector. This fits into the 5
pin female DIN connector located on the connector side of the Smart Trigger controller.

TS ENGINEERING, INC.
Operation setup (Quick start)
The controller is designed and factory preset to require very few adjustments. On most
feeders only the following setup procedure should be required.
1. You may wish to replace the controller fuse (factory value is 15 amps fast blow) with one
which is rated for the maximum drive coil current rating of your feeder to prevent
accidental over driving. Do not use a fuse rated over 15 Amps for any model!
2. Plug the Smart Trigger into a standard outlet rated to deliver 95-140 Volts RMS AC @
50/60 Hertz for the 110 volt models or 190-250 Volts RMS AC @ 50/60 Hertz for the
220 volt models.
r
USE OF AN INPUT VOLTAGE HIGHER THAN THE RATED MAXIMUM (140 VOLTS
RMS AC OR 250 VOLTS RMS AC) CAN DAMAGE THE CONTROLLER AND VOID
YOUR WARRANTY!
3. Connect the drive coils of your feeder to the output connector.
4. Turn on the unit via the Power switch located on the right side of the unit.
5. Upon power up there is a 0.2-second pause for internal calibration that may be followed
by a soft start delay of 0.8 seconds (depending on the setting of DIP switch 3), after
which the controller will begin normal operation.
6. Adjust the Vibration Intensity (set point adjust) knob to achieve the desired amplitude of
vibration. The controller will then maintain this vibration intensity level independent of
any line voltage fluctuations.

Dip switch and jumper functions (all models)
This section describes some of the advanced features that are available for use with the unit
as well as suggested adjustments to enhance feeder performance.
A note about DIP switches 1 and 2
The universal operate / hold and emergency operate / hold functions work together to control
the Smart Trigger. If both functions are enabled, they must BOTH be commanded to operate
(run) mode to produce an output. If either of them selects hold (stop), the output will be
stopped.
DIP switch 1 - Universal input for operate / hold (see figure 6 or 7)
If enabled (with jumpers JMC and JMD removed), any AC or DC voltage from 5 Volts RMS
(minimum) to 120 Volts RMS (maximum) applied to TB3 terminals 5 and 6 will put the unit
in operate (run) mode. Removal of this voltage will cause the unit to hold (stop). This input
is optically isolated from all other internal circuitry when jumpers JMC and JMD are
removed. Installing jumpers JMC and JMD (factory default) allows this input to be used by
the photo sensor input at TB3 terminals 1, 2 and 3 on all models. See page 31 for details.
On ST-X400 models, an external 10 to 30 VDC power supply must be connected to TB2
terminals 11 (+) and 12 (-) to supply power to the photo sensor and internal electronics to
operate as above with jumpers JMC and JMD installed (factory default). An external power
supply is not required to use the voltage controlled operate / hold function as described above
with jumpers JMC and JMD removed.
This function can also be controlled by a dry contact closure (switch) applied to TB3
terminals 7 and 8. A contact closure will cause the unit to hold (stop). Opening the contacts
will cause the unit to operate (run). The time delay controls ON (R14) and OFF (R23) ONLY
apply to this input. See page 23 for details and note the warning below.
Switch 1 = open
Switch 1 = closed
r
Universal input enabled
Universal input disabled
(factory default)
CONTACT CLOSURE MEANS A NON-POWERED DRY CONTACT. IF ANY
VOLTAGE IS APPLIED TO THE CONTACT CLOSURE INPUTS, SEVERE DAMAGE
MAY OCCUR TO UNIT. THIS IS MEANT TO BE A SWITCH, RELAY CONTACT OR
OTHER NON-POWERED CONNECTION. APPLYING ANY VOLTAGE ACROSS THE
CONTACT CLOSURE INPUTS MAY DAMAGE THE CIRCUIT AND VOID YOUR
WARRANTY!
16
TS ENGINEERING, INC.
DIP switch 2 - Universal input for emergency operate / hold (see figure 6 or 7)
If enabled with jumpers JME and JMF removed (factory default), any AC or DC voltage
from 5 Volts RMS (minimum) to 120 Volts RMS (maximum) applied to TB3 terminals 9 and
10 will put the unit in operate (run) mode. Removal of this voltage will cause the unit to hold
(stop). This input is optically isolated from all other internal circuitry when jumpers JME and
JMF are removed (factory default). Installing jumpers JME and JMF allows this input to be
used by the photo sensor input at TB3 terminals 1, 2 and 3 on all models. See page 31 for
details.
On ST-X400 models, an external 10 to 30 VDC power supply must be connected to TB2
terminals 11 (+) and 12 (-) to supply power to the photo sensor and internal electronics to
operate as above with jumpers JME and JMF installed. An external power supply is not
required to use the voltage controlled operate / hold function above with jumpers JME and
JMF removed (factory default).
This function can also be controlled by a dry contact closure (switch) applied to TB3
terminals 11 and 12. A contact closure will cause the unit to hold (stop). Opening the
contacts will cause the unit to operate (run). The ON (R14) and OFF (R23) time delays DO
NOT apply to this EMERGENCY input. This allows instant EMERGENCY operate (run) /
hold (stop) control of the unit. See page 24 for details and note the warning below.
Switch 2 = open
Switch 2 = closed
r
Emergency universal input enabled
Emergency universal input disabled
(factory default)
CONTACT CLOSURE MEANS A NON-POWERED DRY CONTACT. IF ANY
VOLTAGE IS APPLIED TO THE CONTACT CLOSURE INPUTS, SEVERE DAMAGE
MAY OCCUR TO UNIT. THIS IS MEANT TO BE A SWITCH, RELAY CONTACT OR
OTHER NON-POWERED CONNECTION. APPLYING ANY VOLTAGE ACROSS THE
CONTACT CLOSURE INPUTS MAY DAMAGE THE CIRCUIT AND VOID YOUR
WARRANTY!

TS ENGINEERING, INC.
DIP switch 3 - Soft start (see figure 6 or 7)
Enabling the soft start causes power to the feeder bowl to ramp up to the set point over a
period of approximately 0.8 seconds when switching from hold (stop) to operate (run) mode.
This will prevent surges associated with starting the feeder while running at high output
levels. Disabling the soft start causes the controller to return directly to the setpoint with no
delay when switching from hold (stop) to operate (run).
Switch 3 = open
Switch 3 = closed
Soft start disabled
Soft start enabled
(factory default)
DIP switches 4 and 5 - Power output range select (open loop mode) (see figure 6 or 7)
When operating in open-loop mode (WITHOUT a motion sensor connected), DIP switches 4
and 5 control the maximum output power to the feeder reducing it from 100% to 75% to 50%
to 37.5% of maximum. This improves the resolution of the vibration intensity (set point)
control and limits the output power for devices that operate at lower power levels than the
maximum output level the controller is capable of delivering.
This range can be further fine tuned with the maximum amplitude limit control (R34) near
TB2 on all models. Adjusting R34 fully counterclockwise selects the maximum amplitude in
the range. Adjusting R34 full clockwise selects the minimum amplitude in the range. R34 is
factory set to its midpoint, but it may be adjusted as needed by the end user. R34 is a single
turn control and it can be damaged by rotation beyond its stops.

DIP switches 4 and 5 - Sensor gain select (closed loop mode) (see figure 6 or 7)
When operating in closed-loop mode (WITH a motion sensor connected), DIP switches 4
and 5 control the motion sensor circuitry gain. This allows matching of the range of the
vibration intensity (set point) control to the required physical motion of the feeder. Higher
motion sensor gain values will result in lower vibration levels. For devices that move a lot
with very low power input, a gain of 8 may be required. For feeder devices that require a lot
of power to generate the required motion, lower motion sensor gain values will work best.
The motion sensor gain can be further fine tuned with the maximum amplitude limit control
(R34) near TB2 on all models. Adjusting R34 fully counterclockwise selects the maximum
amplitude in the range. Adjusting R34 full clockwise selects the minimum amplitude in the
range. R34 is factory set to its midpoint, but it may be adjusted as needed by the end user.
R34 is a single turn control and it can be damaged by rotation beyond its stops.

DIP switch 6 - Phase select (see figure 6 or 7)
This feature selects which cycle of the AC power mains input is used by the Smart Trigger to
produce an output. This setting is relevant ONLY on the 30 Hz and 60 Hz output settings (25
Hz and 50 Hz on 50 Hz source lines) since they operate only on one half of the AC input.
The 40 Hz and 120 Hz settings (33.3 Hz and 100 Hz on 50 Hz source lines) use both halves
of the AC input. This allows the user to balance the load equally on both halves of the AC
power mains input.
For example, if four equal sized 60 Hz feeders were being run on the same AC circuit, it is
recommended to set two of them to the positive phase and two to the negative phase to
balance the load on the AC power mains. If operating three feeders on the same AC circuit,
moving the one that generates the highest output power to the opposite phase of the other two
will help balance the load on the AC power mains.

DIP switches 7 and 8 - Output frequency (see figure 6 or 7)
This feature changes the output frequency of the Smart Trigger. The available output
frequencies are dependent on the frequency of the AC power input line as illustrated below:
Switch 7 = closed
Switch 8 = closed
Input = 60 Hz, Output = 120 Hz
Input = 50 Hz, Output = 100 Hz

Switch 7 = open
Switch 8 = open
Input = 60 Hz, Output = 30 Hz
Input = 50 Hz, Output = 25 Hz
(factory default)
DIP switch 9 - Closed loop gain selection (see figure 6 or 7)
This feature controls the response time of the Smart Trigger in the closed loop mode (WITH
a motion sensor connected) to sudden changes in the vibration intensity of the feeder due to
parts loading, power line fluctuations or rapid changes to the vibration intensity (set point)
control. This switch has no effect in the open loop mode (WITHOUT a motion sensor
connected). Use the high loop gain setting for the fastest response. If the feeder vibration
intensity oscillates, use the low gain setting.
Switch 9 = open
Switch 9 = closed
Loop gain high

Jumper Settings JMA thru JMF
NOTE: A storage header labeled JMG is provided on all models located next to TB2
terminal 1. Place all unused jumpers on JMG to prevent their loss.
JMA - Installing jumper JMA (factory default) enables control of the Smart Trigger with the
front panel vibration intensity (set point) adjustment. Removing JMA switches control of the
Smart Trigger output level to an external 0 to +5VDC control voltage or a 0 to +20 ma
current source. DO NOT EXCEED +5VDC OR +20 MA OR APPLY A NEGATIVE
EXTERNAL CONTROL VOLTAGE OR CURRENT.
For ST-X400 models, removing JMA enables (0 to +5VDC) output level control input at
TB2 terminals 7 (+0 to +5VDC) and 8 (ground). For 0 to 20 ma current source control, a 270
Ohm 1/4 watt or higher resistor must be added across TB2 terminals 7 and 8.
For ST-X900 models, removing JMA enables (0 to +5VDC) output level control input at
TB2 terminals 8 (+0 to +5VDC) and 6 (ground). For a 0 to 20 ma current source, the control
input is connected to TB2 terminals 10 (0 to +20 ma) and 6 (ground).
JMB - (ST-X900 models only) – JMB configures TB2 terminal 9. It has 3 terminals (two
possible configurations) and is NOT installed at the factory. Installing JMB on the stake in
the center and the one closest to TB2 terminal 10 will tie TB2 terminal 9 to ground. Installing
JMB on the stake in the center and the one closest to TB2 terminal 1 will tie TB2 terminal 9
to the on board adjustable power supply output. DO NOT DRAW MORE THAN 250 MA
FROM THIS POWER SOURCE.
A note about jumpers JMC, JMD, JME and JMF
Jumpers (JMC with JMD) and (JME with JMF) work in pairs to assign the photo sensor
input at TB3 terminals 1 (+), 2 (photo sensor signal) and 3 (ground) to the universal operate /
hold OR universal emergency operate / hold functions. You may choose one or the other, but
choosing both functions together serves no useful purpose. Installing jumpers JMC and JMD
will conflict with using the voltage controlled universal operate / hold input at TB3 terminals
5 and 6. Installing jumpers JME and JMF will conflict with using the voltage controlled
universal emergency operate / hold input at TB3 terminals 9 and 10.
These jumpers have no effect on the universal operate / hold contact closure input at TB3
terminals 7 (switch) and 8 (ground) OR the universal emergency operate / hold contact
closure input at TB3 terminals 9 (switch) and 10 (ground).
JMC and JMD – Installing these jumpers (factory default) configures the photo sensor input
to control the universal operate (run) / hold (stop) input that is enabled with DIP switch 1.
JME and JMF – Installing these jumpers (not factory installed) configures the photo sensor
input to control the universal emergency operate (run) / hold (stop) input that is enabled with
DIP switch 2.

Internal adjustments (all models)
(R6) +10 to 35 volt power supply adjustment (ST-1900 / ST-2900 only) (see figure 5)
This control is factory set to +24.5 volts DC. It is used to adjust the internal power supply
output voltage used to operate the photo sensor connected to TB3 terminals 1, 2 and 3. The
specified range of this adjustment is from +10 volts DC to +35 volts DC. Its maximum range
is +9 to +42.5 VDC (DO NOT EXCEED +35VDC). This is a 10 turn control with a clutch. A
click can be heard when rotating this control past its limits, but no damage to the control will
occur. The click means that no further adjustment in that direction is possible. Clockwise
rotation raises the output voltage; counterclockwise rotation reduces the output voltage.
The photo sensor is connected to TB3 terminals 1 (V+), 2 (photo sensor signal) and 3
(ground). On ST-XX00-P models, this connection is available on the enclosure 4 pin female
photo sensor connector (see figure 1) as follows: 1 (V+), 2 (not used), 3 (ground) and 4
(photo sensor signal).
(R14) On delay (all models) (see figure 4 or 5)
R14 is an adjustable time delay that may be set by the user if required. This timer begins
running at the start of the command to operate (run) from the universal operate / hold input.
The output signal is held off until this timer runs out. The timer range is 0 to 17 seconds.
Clockwise rotation reduces this time delay, counterclockwise rotation increases the delay.
Use caution when adjusting this control. This is a single turn control and it can be damaged
by rotation beyond its stops. The factory default setting for the on delay is zero seconds. Any
change from operate to hold, or hold to operate will reset this timer. This delay only applies
to the universal operate / hold input. The emergency operate / hold input has no delay.
(R23) Off delay (all models) (see figure 4 or 5)
R23 is an adjustable time delay that may be set by the user if required. This timer begins
running at the start of the command to hold (stop) from the universal operate / hold input.
The output signal continues until this timer runs out. The timer range is 0 to 17 seconds.
Clockwise rotation reduces this time delay, counterclockwise rotation increases the delay.
Use caution when adjusting this control. This is a single turn control and it can be damaged
by rotation beyond its stops. The factory default setting for the off delay is zero seconds. Any
change from operate to hold, or hold to operate will reset this timer. This delay only applies
to the universal operate / hold input. The emergency operate / hold input has no delay.
(R34) Maximum amplitude limit (all models) (see figure 4 or 5)
R34 adjusts the maximum output power from the Smart Trigger. The range of this control is
set with DIP switches 4 and 5 in closed and open loop modes. Counterclockwise rotation
increases the output power; clockwise rotation reduces the output power. This is a single turn
control and it can be damaged by rotation beyond its stops. R34 is factory set to its midpoint.

CONTACT CLOSURE IS A NON-POWERED DRY CONTACT. IF ANY VOLTAGE IS
APPLIED TO THE CONTACT CLOSURE INPUTS, SEVERE DAMAGE MAY OCCUR
TO THE UNIT AND WILL VOID THE WARRANTY.
Connecting a switch across TB3 terminals 7 and 8 will provide the ability to switch between
operate and hold conditions remotely. A switch closure will put the unit in hold (stop) mode
after the time delay (if any) determined by R23. Opening the switch will put the unit in
operate (run) mode after the time delay (if any) determined by R14. See page 22 for setting
these time delays. DIP switch 1 must be closed to enable this operate / hold contact closure
function without any voltage applied to the universal operate / hold input below.
With DIP switch 1 open (to enable the voltage controlled input below), closing this remote
switch will force the unit to hold (stop) if the control voltage below is applied. In this
condition, removal of the control voltage below has priority and will hold (stop) the output.
Opening the remote switch in this case will NOT restart the output until the control voltage
below is reapplied.

Voltage controlled universal operate / hold input
See figures 4 and 6 (ST-X400) or figures 7 and 9 (ST-X900)
DIP switch 1 must be open to enable this universal input. The universal operate / hold input
allows remote control with a switchable voltage source. Any voltage, AC or DC, from 5
Volts RMS minimum to 120 Volts RMS maximum applied to TB3 terminals 5 and 6 will put
the unit in operate (run) mode after the time delay (if any) specified by R14. Removing the
voltage input applied to TB3 terminals 5 and 6 will put the unit in hold (stop) mode after the
time delay (if any) specified by R23. See page 22 for setting these time delays.
NOTE: If no voltage is applied to this input and DIP switch 1 is open, upon power up, the
unit will run until the off delay times out. The unit will then go into hold mode. The
contact closure input (TB3 terminals 7 and 8) will NOT function normally with this
voltage removed and DIP switch 1 open.
The ON time delay (R14) and OFF time delay (R23) functions ONLY apply to the universal
operate / hold input. The universal emergency operate / hold function does not use the timers.
If the timers are both set for 10 seconds and the operate OR hold command is sent, removed
then sent again in less than 10 seconds, the timers will not allow the Smart Trigger to change
modes.

The +5 volt interlock / status output
See figures 4 and 6 (ST-X400) or figures 7 and 9 (ST-X900)
Extreme care should be used when connecting to TB3 terminal 4 since this is a direct
connection to the micro controller. This output follows the actual operate (run) / hold (stop)
modes of the Smart Trigger. In operate (run) mode, this output is +5VDC. In hold (stop)
mode, this output is 0VDC with reference to ground at TB3 terminal 3. This output can be
used as a status indicator to drive a LED (with a 1K Ohm resistor in series), a high
impedance PLC input or other devices with appropriate buffering. The most common use of
this interlock signal is to control another Smart Trigger (interlocking). DO NOT DRAW
MORE THAN 20 MA FROM THIS OUTPUT.
Using the +5 volt interlock / status output
To interlock two Smart Triggers in a master / slave configuration, connect the master unit
TB3 terminal 4 to the slave unit at TB3 terminal 5 (for an adjustable on / off time delayed
slave) and connect the master unit TB3 terminal 3 (ground) to the slave unit TB3 terminal 6.
Remove jumpers JMC and JMD on the slave unit. Removing these jumpers will disconnect
the slave photo sensor input from the universal operate / hold input. Set the slave DIP switch
1 to “open”. The slave unit will now be controlled by (interlocked to) the master unit. In this
configuration, when the master unit is commanded to hold (stop), the slave will hold (stop)
after the time delay set with the off delay (R23) on the slave unit. The slave will remain in
hold (stop) until the master unit is commanded to operate (run) mode AND the on time delay
(R14) on the slave unit has expired.
If no delays are needed for slave operation OR if the photo sensor input to the slave unit is
also required, the universal emergency operate / hold input to the slave unit can be used for
interlocking. To do this, connect the master TB3 terminal 4 to the slave TB3 terminal 9 and
the master TB3 terminal 3 (ground) to the slave TB3 terminal 10. Ensure that jumpers JME
and JMF are removed and DIP switch 2 on the slave is set to “open”.

Motion sensor cable color coding and wiring details
There are two different motion sensors available for the Smart Trigger. They are functionally
the same and can be distinguished by the cable color and attached connector as shown below:
Part #
Description
61-1016-1L Gray cable with threaded DIN connector
61-1016-AB Tan cable with push on DIN connector
Units ordered without an enclosure (-OFK models for "Open Frame Kit") are shipped with a
61-1016-AB motion sensor (tan cable and push on DIN). There has been a change in the wire
colors in these sensors. To identify the sensor you're working with, look at the DIN
connector strain relief near the indexing key.
If the word "TOP" and an arrow pointing to the key are found, this is an "Old Cable Color"
unit. If the number "00-901-50078" and no arrow are found, this is a "New Cable Color"
unit.
The motion sensor and its cable/connector assembly are shielded. This shield MUST be
connected to the PC board ground for proper operation. If the DIN connector is removed
from the motion sensor assembly and the cable is directly connected to the terminal block,
the following connections are required:

If the DIN connector is used with the supplied female chassis connector, a shielded cable
MUST be used from the terminal block to the solder connections at the female chassis
connector. Please note that the ground and shield connections are jumpered on the supplied
female DIN connector. Your shielded cable ground AND shield need connected to pin 2 on
the DIN.
Please pay special attention to the DIN connector pin out as the pins are not numbered
sequentially. The female chassis connector when viewed from the rear solder connections
with the key facing up is numbered as follows starting at the key and moving counter
clockwise around the connector: 1,4,2,5,3.
Ensure that there are no solder bridges between the DIN pins before applying power. Pins 3
and 4 are not used for normal operation. They are used only for calibration and quality
control testing of the motion sensor assembly. Any connections to them may cause improper
operation or damage to the unit or motion sensor assembly.

Smart Trigger wiring diagrams and terminal details
The wiring of the Smart Trigger controller is shown in figure 10 (ST-X400) on page 28 and
figure 11 (ST-X900) on page 29. The power connections for the AC input line hot and
neutral connections should be of sufficient gauge to handle the current being used by the
controller and supplied to the feeder. All PC board connections to the Smart Trigger use a
terminal block screw style connection that will accept wire sizes from 12 to 24 AWG. The
actual wire size used for customer installation of –OFK models in an enclosure (see page 31)
should be a minimum of 14 AWG. The wire gauge used will depend on local electrical codes
and regulations.
TB2 terminals 1 (+5VDC), 2 (motion sensor signal), and 3 (ground) are for the motion sensor
interface connection. This connector is only installed on models with a –M suffix
(ST-XX00-M).
TB3 terminals 1 (photo sensor power +), 2 (photo sensor signal) and 3 (ground) are for the
photo sensor interface connection. This connector is only installed on models with a –P
suffix (ST-XX00-P).
On ST-X400 models TB2 terminals 4 (set point top), 5 (set point wiper), 6 (set point
bottom), 9 (power LED +) and 10 (power LED -) are pre-wired with a 22 gauge five
conductor shielded cable. The shield of this cable MUST be connected to the enclosure. The
remaining terminals are all for customer connections.
On ST-X900 models TB2 terminals 4 (set point top), 5 (set point wiper), 6 (set point bottom
and ground) and 7 (power LED +) are pre-wired with a 22 gauge five conductor shielded
cable. The shield of this cable MUST be connected to the enclosure. The remaining terminals
are all for customer connections.

Is AC power input cable unplugged? Plug it in / try another outlet.
Is Smart Trigger power switch off? Turn it on.
Is AC power outlet dead? Power mains need repair.
Power indicator on Is vibration intensity set point control at minimum? Raise set point.
but no output power Are feeder coils bad, broken wiring or not connected? Check / repair.
If DIP sw 1 is open, is AC or DC voltage present at TB3 pins 5 and 6?
If it is > 5 volts and < 120 volts, is TB3 pin 7 grounded by a switch?
If DIP sw 2 is open, is AC or DC voltage present at TB3 pins 9 and 10?
If it is > 5 volts and < 120 volts, is TB3 pin 7 grounded by a switch?
Intermittent / erratic In closed loop mode (WITH a motion sensor), ensure that sensor cable
changes in output
is not near or coiled near AC input or output lines. Is the motion sensor
cable shield grounded? (See page 26). Make sure there are no ground
loops. (Use a single common ground point for ALL feeder controls and
AC input power mains).
In open loop mode (WITHOUT a motion sensor) Make sure there are no
ground loops. (Use a single common ground point for ALL feeder
controls and AC input power mains).
Unit runs briefly
after power up,
then stops
If DIP sw 1 is open, check for missing operate / hold input voltage at
TB3 pins 5 and 6. If DIP sw 1 is closed, check for a closed switch at
TB3 pins 7 and 8. (See page 23).
