Physical Layout Of GEM

A. Battery1 (Input Power),Battery2, Battery3
Sensing ports
B. DCCT Input
C. External Temperature Sensing
D. Mains Failure Sensing
E. RS485 connection with GT for remote
monitoring
F. Control relays used for remote stop
control of AMF1 and 2
G. GEM3 alarms for NOC (GEM Critical,
GEM Fail, GEM Active)
H. Temperature sensing port. Decision to
release AMF is taken on the basis of it
I. Built in +12VDC power supply
J. Status LEDs
1. Power: System Powered Up
2. Active: GEM Active (AMF on hold) &
Batteries are still healthy (In
Discharge Mode)
3. Alarm: Low Battery Voltage/ High
Temp/ GENSET Fail Alarm
K. Setting Switches
