Module Status 0/7 7 [Ready]
[PTC]
[CT Loss]
Displays information about the operational status of the 150-
SM2 PTC, Ground Fault, and External Current Transformer (CT)
Option Module.
Ready
: Bit 0 = Ready; Bit Set =1 indicates the module is ready
for operation.
PTC: Bit 1 = PTC; 1 = PTC Indicating Fault 0; = No fault
CT Loss: Bit 2 = CT Loss; 1 = CT disconnected; 0 = CT
Connected
