SPECIAL INSTRUCTION: RFID actuator – RESET.
In the event that a Fault condition requires reset, follow the reset instructions:
1)
Turn off all power to the switch and open the guard.
2)
Remove the switch cover.
3)
Using a 2mm terminal screwdriver hold down the RESET button inside the switch housing and turn on the switch
power (see Fig.2).
4)
Release the RESET button, the yellow LED will flash, close the guard and the yellow LED will turn steady yellow.
(If yellow LED continues to flash check for mechanical fault (e.g. damaged actuator or switch head)).
5)
Turn power off and then on, the green LED will illuminate.
6)
Re-fit the switch cover.
7)
Open and close the guard ensuring all safety functions are correct –refer to any risk assessment for the particular
guard application.
