3.0 OPERATION
Operation
The inverter that is connected to the ALM monitors its battery voltage to
determine when to signal relays RY9 and RY10. These relays are individually
controlled and each responds to user-programmable, voltage setpoints via the
inverter’s control panel. These two auxiliary relays operate independently of the
inverter’s status - whether the inverter is ON or OFF.
The software revision of your inverter determines whether RY9 and RY10
operate as active-high or active-low type relays. This depends on whether the
inverter has:
1) the programming to allow for a “user-defined delay” when the relay energizes
or de-energizes,
2) a hysteresis voltage setting (the difference between the relay activation and
deactivation), or
3) a temperature compensation setting.
For specifics on the operation, programming, and adjustment values for the
ALM, refer to your inverter’s manual (Auxiliary Relay section).
Active-High Type Relay
This relay type energizes when the voltage is above the high-voltage setpoint
and de-energizes when the voltage goes below the low-voltage setpoint.
Active-Low Type Relay
This relay type energizes when the voltage is below the low-voltage setpoint
and de-energizes when the voltage goes above the high-voltage setpoint.
ALM Applications
There are a number of applications for the ALM. These applications are based
on the configuration of the relays – whether configured active-high or active-low.
