Functional
Test:
A simulated current equal to 120% of the trip current set on the Trip Level DIPswitches replaces the measured
current. This tests all internal electronics and secondary windings of the built-in current transformers. No
external power supply or additional wiring is required.
Local Test................................................................................................... Double click RESET button on front of relay
Remote Test...................................................Double click button connected to terminals R1 and R2 or via D64DMCC
Reset...................................................................................................... Single push of RESET button on front of relay
Remote Reset ........................................... Single push of button connected to terminals R1 and R2 or via D64DMCC
