6.3 Internal Trips
The Protection Element has a number of trip functions that are not directly associated with the protection
of the outlet, but signal that other dangerous faults have been detected.
6.3.1 CCM ID
The Protection Element has an internal detection circuit to identify the CCM module that is assembled
within the Cassette. If the CCM identity fails to match with that which is expected, the Protection
Element will set this trip. There is currently one CCM version which is used for both 1.1kV and 3.3kV
outlets. If this trip occurs the Cassette should be returned for repair.
6.3.2 MCF Battery Trip
The Protection Element has an internal battery. This is used to power the real time clock (used to
timestamp log messages) as well has power the main contactor fail latch. The health of this battery is
monitored and if the battery condition is failing this trip will be set. If this trip occurs the Protection
Element should be returned to have the battery repaired or replaced.
6.3.3 Internal Logic Error
This trip will be set in the event that an internal fault has been detected. If this trip occurs the Cassette
should be returned for repair.
