3 Description of Controls

3-1 Access to Controls

All switches and terminal blocks located on internal printed circuit assemblies (PCA) are accessed by removing
the four captive screws which hold the emitter and receiver rear covers in place. For ease of access the PCA
will slide approximately 1/2 way out of the housing. A stop is installed to keep the PCA from sliding completely
out of the housing.
On emitter and receiver models two ports, threaded PG9 are provided for entry of cables. One is on the bottom
surface and one is on the rear cover. A threaded plug is provided for the unused port.

3-1-1 Emitter Indicator Lights

The front panel of the emitter has two indicator lights:
Amber Indicates that the emitter has powered-up correctly.
Red Indicates that a emitter fault (DIP switch set to invalid setting or changed after power-up)
was detected after application of power.

3-1-2 Receiver Indicator Lights

The front panel of the receiver has four indicator lights:
Green Run. The infrared beam is not interrupted.
Red Stop. The infrared beam has been interrupted or is out of alignment.
Yellow Interlock. The system has interlocked. The fault must be corrected before the system can be
reset.
Amber Signal Strength. For use as an alignment aid. Status interpreted as follows:
Steady on: Strong Signal Strength
Flashing: Weak Signal Strength
Off: Out of Alignment or Beam Blocked.
A flashing signal strength indicator may be acceptable at long range or when using mirrors
in an installation.
The rear panel of the receiver has two diagnostic indicator lights labeled F1 and F2. These lights flash at different
rates to provide troubleshooting assistance. The faults indicated by the number of flashes are detailed in the
troubleshooting section of this manual.
