Page 35

Circuit Breaker/ Fuse Test:

1.For plug- in circuit breakers. Monitor alarm screen for circuit breaker alarm while shorting out each pair of alarm contacts (using a pair of tweezers) on the circuit breaker interface circuit board. Verify proper voltage at the circuit breaker common bus.

2.For fuses: Monitor alarm screen for fuse alarm while removing fuses from each position. Verify proper voltage at fuse common bus.

3.Turn on fuses and circuit breakers as desired.

User Inputs

1.Change the user input to desired alarm via the controller for any input that will be used.

2.Exercise the alarm by causing the input to change state.

3.Verify the desired relay output on the controller module.

Output Relays:

1.Change the alarm parameter to desired relay output via the controller for any relay output that will be used. All alarm parameters are shipped as either major or minor, but may be changed to any of 6 output relays.

2.Program out put relay to desired major or minor alarm to complete programming.

3.Exercise the output relay by causing the alarm to change state.

4.Verify the desired relay output on the controller module.

Battery Temperature Compensation

1.Enable battery temperature compensation if desired.

2.Ensure that battery temperature probe is connected to the system and attached to the battery.

3.Verify that the system voltage is above the float voltage if the battery temperature is below 25 degrees C and below the float voltage if the battery temperature is above 25 degrees C.
