LED Diagnostic Functions:
LED1 Steady Yellow
Fault (See special instruction RESET)
LED1 Yellow/Green Alternate Flashing
Tag not recognised or not present.
Special Instruction: RFID actuator – RESET.
In the event that a Fault condition requires reset, follow the reset instructions
in the correct sequence:
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 and the yellow LED will begin to 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.
