CHAPTER 7: MAINTENANCE M7 TESTING
350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 7–19
Force output relays
For testing purposes, the 350 relay provides the ability to override the normal function of
the output contacts. This is done by forcing each of them to ON or OFF.
The following path is available using the keypad. For instructions on how to use the
keypad, please refer to Chapter 3 - Working with the Keypad.
PATH: MAINTENANCE > M7 TESTING > FORCE LEDS
FORCE OUTP RELAYS
Range: Disabled, Enabled
Default: Disabled
Set FORCE OUTP RELAYS to "Enabled" to override the normal operation of the output
contact, with the programmed state.
When the FORCE OUTP RELAYS setpoint is set to Enabled, the relay Maintenance LED
starts flashing (faceplate option E), the In-service LED turns off, the Trouble LED starts
blinking orange, and the Critical Failure Relay is de-energized, indicating the relay is in
test mode. Output relays may then be turned on and off individually using the setpoints
listed below.
NOTE:
Note that the FORCE OUTP RELAYS setpoint will always default to the Disabled state at
power up.
RELAY 1 TRIP
RELAY 2 CLOSE
RELAY X AUXILIARY
Range: Off, On
Default: Off
Select "On" to energize the output, and "Off" to de-energize it. When energized, the
normally open contact of the output relay will close, and the normally closed contact will
open. FORCE OUTP RELAYS must be set to "Enabled" for this setting to take effect.
