E-Z Cal Major Hardware Components
The E-Z Cal hardware is comprised of two major components: the Manual
Station and the IO Box.
The Manual Station is a backup control panel that allows you to manually
operate any plant device without depending on the batch control computer.
The IO Box (also called a J-Box) is an integral part of the E-Z Cal. Whereas
the Manual Station is the “operator interface”, the IO Box is the “electrical
interface”.
Manual Station
CAUTIONS!
This equipment was manufactured to operate under
normal “dry” industrial conditions. Extreme
temperature or weather conditions can and will cause
damage to the equipment and bodily harm.
Per IEC 61010, no operator access is permitted in this
unit! Service should only be performed by qualified
personnel.
A Circuit Breaker (rated at 20 Amperes 240 Volts AC)
should be installed near the IO Box, be easily
distinguishable from other controls, and labeled to
indicate that it is the Disconnect device.
Warning!
HAZARDOUS LIVE VOLTAGE PRESENT! This equipment
must be isolated or disconnected before it is accessed.
Description
The E-Z Cal Manual Station is a backup control panel that allows you to
manually operate any plant device without depending on the batch control
computer.
Each button, light, and display on the Manual Station is labeled to indicate its
function. If this is your first time using the E-Z Cal, spend a few moments to
locate the most commonly used controls such as scale displays and discharge
gate pushbuttons (see the E-Z Cal Front Panel drawing).

Features
•
Reliabilility: With easy to replace, low-voltage buttons, which can last up
to 20 times longer than the high-voltage types used by other companies,
and easily reassignable IO points, EZ-Cal is built for the long haul.
•
Digital signals are used throughout E-Z Cal, making drifting scale values
next to impossible.
•
Up to 12 Simultaneous Displays & 80 Manual Controls can be configured.
•
E-Z Cal automatically tests for load cell failure, potentially preventing bad
loads, wasted material, and unhappy customers.
•
E-Z cal uses a standard PC connected to the IO system with one proven,
reliable RS-232 cable.
•
E-Z Cal is enterprise-upgradeable, meaning it can easily be connected to
a Dispatch system via a TCP/IP connection.
Nameplate Label
The manual station’s nameplate label is located at the top of the left side
panel as shown in the following picture. The nameplate label contains
important information such as the voltage range, frequency, current,
operating temperature, CE mark and NTEP certification number.

Description
The IO Box (also called a J-Box) is an integral part of the E-Z Cal. Whereas
the Manual Station is the “operator interface”, the IO Box is the “electrical
interface”. The IO Box fuses incoming plant power with a main fuse and
sectional hot power and neutral voltages. With the provided power cable, the
voltages of the plant power can be kept in phase and on the same source as
the computer power.
All plant control signals flow to and from the batch computer through the IO
Box. These signals include scale, meter, moisture probe and limit switch
inputs to the computer, as well as the on-off solenoid valve and motor control
signals from the computer to the plant. LED lights on the Power Supply Board
indicate whether power is on for the Supply Power and the Manual Station.
(See the IO Box Layout and Power Overview.)
The IO Box contains no electrical components such as motors, high-voltage
transformers, or solenoids (refer to your plant drawings for the location of
these components).
Plant devices not directly controlled by the batch computer can be wired to be
controlled from the IO Box. Examples are air compressors and cement
aerators.

Clearing Bad Cell and Bad Module Messages
The E-Z Cal performs a quick check of the load cells, cables, and electronics
approximately every 10 minutes. If a problem is detected, one of the following
messages flashes on the affected display, alternating with the scale weight or
moisture reading (which might be incorrect!):
BAD CELL
BAD LCIu
BAD LCIv
BAD MPIu
Notes: •
•
See E-Z Cal Displays for a description of each message.
The BAD LCIu and BAD LCIv messages will only be displayed if
the E-Z Cal firmware version is 1.01D or higher.
The message continues to be displayed after the problem is corrected. This
allows you to be aware of a problem that comes and goes by itself.
After you have diagnosed and fixed the problem, press the “Setup” button.
The displays show something like:
Bad cell

Press the Up/Down buttons to select Yes and press Enter.
A message will be displayed for each scale or moisture probe that has a
problem. After all of the messages have been accepted with Yes or No, press
the “Setup” button to return the system to normal operation.

•
In Setup mode, each E-Z Cal display can be configured to show readings
for one of the following: a scale, a meter, or a moisture probe. A display
can be configured to show scale, meter, or moisture probe information
with a variety of options such as unit of measure, decimal point position,
etc. Active displays can be disabled.
•
In Calibrate mode, you adjust the E-Z Cal displays to match the actual
weight on the scales, or the actual value of aggregate moisture.
•
In Info mode, you can view configuration settings for each display, view
system information such as firmware and software versions, and turn
scale certification (i.e. NTEP) on or off.
Note: Do not proceed beyond this point unless you intend to
reconfigure one or more scales or meters.
Caution!
If you plan to change any scale parameters, make sure you
have the proper test weights, training, and time to re-check
the weighing accuracy of those scales. Careless setup will
cause serious batching errors that the batch computer will
not be able to correct!

Calibration Enable Switch
To prevent accidental changes to scale setup and calibration data, the E-Z Cal
has an internal Calibration Enable Switch that can be locked. Normally this
switch is set to the “locked” position by your system installer.
Note: You do not need to unlock the Calibration Enable Switch to change
the setup or calibration of counters or moisture probes.
To Unlock the Calibration Enable Switch
1.
(Optional, depending on government regulations for your area):
Remove the calibration wire seal from the small blue metal tab on
the rear panel (see the following picture).

Setup Procedures
Use these procedures to configure (set up) scales, counters, moisture probes,
and generic analog inputs.
•
These devices should be configured in the E-Z Cal before you set them up
in the batch control software.
•
For Scales, you can assign the measuring system (U.S. or SI), unit, grad
size, decimal point location, and allowed grads for re-zeroing the scale.
•
For Counters, you can assign the measuring system (US or SI), unit,
grad size, and decimal point location.
•
For Moisture Probes, all you need to do is select the probe module
position (choices are 1 - 8).
•
For Generic Analog Inputs, you can assign the measuring system (U.S.
or SI), unit, grad size, decimal point location, and allowed counts for rezeroing the reading.

Full-Scale Calibration Completed
At this point, one of three things can occur:
•
The displays may show “Cell output too low.” This means the load cell
is grossly oversized or that there is a wiring problem. In technical terms,
it means that the load cell’s “span” (the difference in its output voltage
between zero and full scale) is less than 1.6 millivolts. A properly sized
load cell will have a span in the range of 5 to 15 millivolts. (The E-Z Cal
uses an excitation voltage of 5 volts.) Contact your scale manufacturer.
•
The displays may show “Cell output too high.” This means the load cell
is grossly undersized or that there is a wiring problem. In technical terms,
it means that the load cell’s full-scale output voltage is greater than 23
millivolts. A properly sized load cell will never have an output more than
about 16 millivolts. Contact your scale manufacturer.
•
Or, if all goes well, the displays show:

Use the Up/Down buttons to select “No” then press Enter. “No”
exits setup and returns to the normal weight display mode.
2.
Remove the test weights from the scale, and verify that the
display goes back to its starting point.
3.
Manually batch an amount of material which is approximately the
same as the total weight of the test weights.
4.
Add the test weights back onto the scale. The E-Z Cal display
should show a value equal to the sum of the material weight in
step 3 plus the test weights.
5.
Repeat steps 2 - 4 until the scale’s capacity is reached.
6.
If the displays do not track with the expected weight values, you
may want to repeat the entire calibration process.
7.
When calibration is completed, remove all material from the
hopper, and remove the chains or weight platform from the scale.
The displays show a negative value. Press the “Zero” button for
that scale.

strain gauge force transducers” also per Western Regional Strain Gauge
Committee Standard.
•
This cross reference chart allows you to replace one brand load cell with
another when they have the same output (mv/v) and the same physical
size.
•
To correct an instrument that displays a weight in the wrong direction,
interchange the +Output and -Output connections.
6/2/14
Example: If the load on the scale is increasing and the instrument
display is decreasing, reverse the Output connections. Do not reverse
the Excitation connections. The readout should now display increasing
readings with increasing load.
