Alarm Module (1) PlugFor all alarm applications, the low DC volts alarm setpoint is adjusted by a potentiometer that is located under access plug (1) on the rear of the module. The adjustment range is from 8 to 38 volts. The factory setting of the alarm setpoint is 24 DCV.Adjustment Procedure
Gain access to the rear of the ALM. Removal of the ALM is not necessary unless removing the ALM is needed for access. All wiring remains connected to the terminals of the ALM unless the step notes otherwise.
Remove plug (1) in order to gain access to the adjustment potentiometer. Moisture may enter the ALM when plug (1) is removed. Remove plug (1) in a dry environment. Remove the plug in an air conditioned area if the relative humidity exceeds 60%.
Disconnect the wires on terminals 1 and 7. Secure these wires so that the wires do not contact each other, ground or other electrical connections.
Connect a variable DC power supply to the alarm module. The positive lead connects to terminal 1. The negative lead connects to terminal 7. Set the power supply voltage to the desired low DCV alarm setpoint. The setpoint must be between 8 and 38 volts.
Turn the adjustment potentiometer clockwise until the potentiometer stops.
After one minute, the indicator on the ALM for low battery voltage FLASHES. Press the alarm silence switch. The low battery voltage indicator should change from FLASHING to ON CONTINUOUSLY.
Slowly turn the adjustment potentiometer counterclockwise until the low battery voltage indicator turns OFF.
Replace the plug.
Disconnect the variable DC power supply and reconnect the wires to terminals 1 and 7.
