Figure 4: Trip coil monitoring logic diagram
Close coil monitoring is performed by a built-in voltage monitor on the Form A output relay:
#2 Close. The voltage monitor is connected across the Form A contact, and effectively the
relay detects healthy current through the circuit. To do that, an external jumper should be
made between terminals "B4", and "B5" for Close coil monitoring.
