The Messenger is located directly above the circuit breaker compartment.
1.3.5 Compartment ID button
The Compartment ID button stores compartment configuration information in non-volatile
memory. It informs the system about the circuit breaker residing in the cubicle.
The Compartment ID button is shipped inserted into the EntelliGuard Messenger, tethered to the
equipment, and does not require any user interface during normal operation. It remains within
the switchgear cubicle at all times.
WARNING! Compartment ID buttons are set at the factory and are not interchangeable
between compartments. Failure to utilize the correct compartment ID button can result in
personal injury and damage to equipment.
The ID button provides the system with necessary information such as circuit breaker frame
size, CT size, and overcurrent protection capabilities as follows:
• Ground fault protection always on
• Ground fault protection always off
• Ground fault protection switchable (enabled/disabled) in the HMI
If the ground fault protection options need to change, a replacement ID button must be ordered
(GE CAT# ETSCOMPID).
