Your Duct-O-Wire CAS-1RA-O Collision Avoidance Kit comes complete with (1) Sensor Unit, (1) Sensor Unit mounting

bracket and hardware, (1) Plug, (1) Bushing, (2) Grommets, (1) Reflector Array and (1) Instruction sheet.

MAKE CERTAIN POWER SUPPLY IS DISCONNECTED BEFORE INSTALLING, REPAIRING, OR MAKING

ADJUSTMENTS TO THIS DEVICE. THIS DEVICE SHOULD BE INSTALLED BY QUALIFIED ELECTRICAL

PERSONNEL ONLY.

THIS PRODUCT IS DESIGNED FOR OPERATING DISTANCES OF 30 FEET MAXIMUM AND THREE

FEET MINIMUM. DO NOT EXCEED THESE DISTANCES.

SENSOR RATING: 3 AMPS MAX

1. When mounting the sensor to the bracket, make sure the screw heads are on the bracket side and the

nuts are captive inside the sensor. Do not over tighten the sensor mounting screws.

2. Wire the sensor with a round cable, properly rated for voltage and application. The rubber bushing must

fit tightly around the cable. Always use the provided plug to seal the remaining entrance. As with all

sensors of this type, it is important to keep dust, moisture and contaminants from the inside of the unit.

The hole size for the cable entry into the sensor unit has been reduced from previous versions. It is

necessary to slide the compression nut and the rubber bushing onto the cable prior to stripping bac k

the outer jacket for wiring. After wiring, fully tighten compression nut prior to reassembling.

3. This sensor operates on 120 VAC. Connect power leads to terminals 1 and 2.

4. Terminals 4 and 5 are normally closed and are the ones generally used for Collision Avoidance

applications. They should be wired in series with the direction circuit to be interrupted.

5. Mount the reflector array securely to a solid object. The reflector array must be centered and

aligned both horizontally and vertically on the same plane as the sensor unit. (see diagram)

6. To adjust the trigger point: (A) With the crane positioned at the trigger point, move the sensor unit

so that the visible red light spot is just to the left or right of the reflector array. (B) Slowly move the

sensor unit towards the center of the reflector array until the indicator light on the sensor switches on.

The visible red light spot will be at the edge of the reflector array. (C) Secure the sensor unit in this

position. (D) Check the switching action by moving closer to and further away from the trigger zone.

(E) Slight adjustment of the sensor unit may be necessary to attain desired switching point.

7. Do not adjust the sensitivity on the sensor unit. It must remain in the factory set, full clockwise,

maximum gain position.

8. If multiple photoelectric units are being used in the same proximity, installation locations must be far

enough apart that there is no chance that one sensor will intercept the light beam from another unit.

9. As with all photoelectric sensors, it is necessary to keep excessive dust or dirt from diminishing the

optical effectiveness of the device. Wiping the sensor's optical surface and the reflector array

occasionally with a moist, not wet, cloth should be made part of a normal maintenance procedure.
