Power Alarm - GE GLM064 User Manual

Chapter 5. Diagnostics

Power Alarm

As documented in Section 3.2, Power Connection, there are two independent power connections, PWR1 and
PWR2. In the event one of these is powered up and is capable of energizing the target GLM switch device, it is
then possible for that GLM Switch device to sense that the alternate Power Supply Input is within specification,
or otherwise. If not, then the corresponding Power Alarm Input is activated.
The P1 and P2 LEDs on the front panel indicate the status of the two power supply inputs, PWR1 and PWR2, as
shown in Section 3.6, LED Operation. The Power Alarms are always enabled.
The Power Alarm Input bits are located as documented in Section 4.3.1, Slot 1: Device Status.
