MESSAGE
To verify correct operation of output relay wiring, each output relay and status indicator can be manually forced
on or off via the keypad or serial port. Testing is only allowed if there is no phase and ground current present
and current simulation is turned off.
If the test is attempted while current is present, the setpoint will be forced to NORMAL MODE and the following
flash message will be displayed for 3 seconds.

RELAY TEST BLOCKED
AMPS SIMULATION ON
If testing is attempted via the serial port while phase or ground current is present or simulation mode is on, an
error code will be returned.
While the OPERATION TEST setpoint is displayed, use the
put relay and/or status indicator to be tested. As long as the test message remains displayed the respective
output relay and/or status indicator will be forced to remain energized. As soon as a new message is selected,
the respective output relay and/or status indicator return to normal operation.
As a safeguard, relay and LED test will turn off automatically if:
• power to the MM3 is turned off and on
• phase or ground current is detected by the MM3
• current simulation is turned on
• new message is displayed
