necessary to obtain exact desired limits (repeat steps 1-6 as necessary).
Pressure Switch Adjustment
1. Bump the rubber safety edge with your hand and observe input X5 on the PLC. If LED does not flash
off or was never on, then adjust the pressure switch. Flip RUN/STOP switch on PLC to the STOP
position to ensure that door is unable to be actuated while performing this adjustment. Remove cover
of pressure switch enclosure (Figure 1. Rotate white plastic screw on pressure switch counter-
clockwise with small screwdriver until LED turns off. Rotate screw clockwise until input LED turns
on. Turn another 1/4 turn. Test safety edge and observe LED (it should turn off momentarily
whenever pressure is applied to safety edge).
2. Flip RUN/STOP switch back to RUN
Final Checks
