Setting Four Alarm Relays, Alarm On, Alarm Value and Alarm
Hysteresis
Alarm Relay
The unit has four relay contacts, which are individually field programmable from 1 to
4. However, the Delay for each Alarm relay can be programmed from 5 to 120
seconds using USB Logger utility only. In case of Demand, the Delay is fixed with 2
seconds. This Delay programming is applicable only for USB utility. Refer last
section, “Programming Mode Using USB Logger Utility”. If user is not desired USB
programming utility, Alarm Delay will be 5 seconds by default only.

SLM102 – Operational Manual
Alarm On
There are seven alarm parameters: Avg. Volts(VOLT), Avg. Amps(AMPS), KVA(VA),
KW(VATT), KVAR(VAR), Demand(DMD), PF(PF) and None(NONE). These parameters
are programmable for each alarm relay according to user’s requirement. In case, any
Alarm parameter is not desired, NONE should be selected.
Alarm Value
Alarm values are freely programmable from 1 to 9999. In case of VOLT, the value is
freely programmable from 1 to 99999. The value indicates the level at which the
relay will close. E.g. If the Alarm On has been selected to KW, and the value is set to
450, the relay will close when the KW exceeds 450 and remains so for 1 minute.
Also, the switching ON logic for PF is reversed. For all parameters, the relay closed
when the parameter value exceeds that defined by Value for more than one minute.
In case of PF however, the relay will close when the PF falls below the Value and
remains so for more than one minute. Also, the PF Value is entered with a
multiplication factor of 1000. e.g. If Second Relay is programmed for which ALARM
ON is set to PF and ALARM VALUE is 955, then the second relay should close when
the PF value falls below 0.955.
Alarm Hysteresis
The last parameter called Hysteresis defines the opening point for the relay which
has closed in response to an alarm condition. This is specified as % of the Value.
Thus, setting Hysteresis of 2 implies that the relay which closes when the parameter
reaches Value, will open when the parameter falls below 0.98 x Value. This is done
to prevent frequent operation / nuisance operation of the relay near the Value.
To set the Alarm Parameters, proceed the following instructions.

Control Outputs
The relay contacts provided in SLM102 are rated for 3A @ 230VAC. They are also
protected by snubbers against fast voltage transients which occur when inductive
loads are switched off. Thus, the following points are to be taken care of when using
these relay contacts:
1. Use 230VAC coils only in the contactors. DO NOT use 440V AC coils.
2. DO NOT switch small loads like electronic Hooters, small relays with 230VAC
coils etc. directly from the relay contact of SLM102. If done so, the small
leakage current from the snubbers will not allow these loads to be switched off
fully. Thus, the electronic hooters will give a low hum continuously, and the
small relays will switch on but not switch off. Use these relay contacts to
switch an Auxiliary contactor and put the load on the contactor contacts.
Alarm Action
Considering two alarm relays with previous section, ”Setting Four Alarm Relays,
Alarm On, Alarm Value and Alarm Hysteresis” in Programming Mode, user can
configure for a desired parameter for alarm control action such as shown below.
Relay 1
Relay 2

SLM102 – Operational Manual
All relays, from 1 to 4 are programmable with the following parameters, Avg. Volts,
Avg. Amps, KVA, KW, KVAR, Demand and PF. The value indicates the level at
which the relay will close. E.g. If the Alarm On has been selected to KW, and the
value is set to 450, the relay will close when KW exceeds 450 and remains so for 1
minute. All parameters have this response time of 1 minute, except Demand which
has a response time of 2 seconds. This is because Demand is already an integrated
parameter.
Also, the switching ON logic in case of PF is reversed. For all parameters, the relay
closed when the parameter value exceeds that defined by Value for more than one
minute. In case of PF however, the relay will close when the PF falls below the Value
and remains so for more than one minute. Also, the PF Value is entered with a
multiplication factor of 1000. e.g. when the second alarm is set for PF and alarm
Value is set to 955, the relay should close when the PF value falls below 0.955
The last parameter called Hysteresis defines the opening point for the relay which
has closed in response to an alarm condition. This is specified as % of the Value.
Thus, setting Hysteresis of 2 implies that the relay which closes when the parameter
reaches Value, will open when the parameter falls below 0.98 x Value. This is done
to prevent frequent operation / nuisance operation of the relay near the Value. E.g. If
the Value has been set to 400, and Hysteresis to 5%, the relay will close when the
parameter reaches 400 and then, the relay opens when it falls below 380. The
response times as outlined above for closing of relays also applies to opening of
relays. Thus, the relay will open at 380 only if the parameter falls below 380 and
remains so for 1 minute (2 seconds in case of Demand).
If all four relays are programmed to close on Demand and different values for closing
and opening are set by the user, SLM102 can be used effectively as a Maximum
Demand Controller with four relay contacts!
SLM102 as a Demand Management
Each relay can be programmed separately to generate alarm on a specific
parameter with its specific value. The value at which it should open is also
programmable. Thus, user could have the first relay programmed to close when the
avg. Voltage exceeds certain value, second when the Avg. Amps exceeds some
level, third for KW, or KVAR or PF or Demand and so on. Before programming the
relays, having a look into Run Mode for Predictive Demand value is true for Demand
Management.
This allows the user to deploy SLM102 as a true Demand manager, to generate
alarm signals for four different conditions!
