Optical Controller Module Replacement
The removal and replacement of the optical controller module for the emitter and receiver units
are identical. The only difference between the various protected height units is the number of
optical extension modules on the optical controller module. See Replacement Part Order
Guide.
1. Remove the power supply module (see Power Supply Module Removal).
2. Turn the retaining rods and slide them out of the housing before removing the optical
controller module (see figure 4-11).

3. Gently pull the optical controller module straight out of the housing (see figure 4-12). With
the plastic support pointed downward and the LEDs or photoreceivers pointed away, lay
the optical controller module down on clean, level work surface.
