OPERATION INFORMATION:A cable is connected from a fixed point to the cable end connection clevis. Pulling on the cable approximately 1/2” will actuate the switch, trip the flag arm down into the walkway and lock the switch in the actuated position. The unit is reset by returning the flag arm to the normal up position.ACTUATION FORCE:Standard units are supplied with an actuation (pull) force of 16 lbs. At no extra charge, units can be factory set at 25 lbs. actuating force.

INSTALLATION INSTRUCTIONS1. Control should be mounted on a flat surface using mounting plate provided.2. Distance between switches should not exceed 200’. Use no more than 100’ of cable per switch end. This is for safety purposes, too much cable can result in a “long pull” situation due to slackness in the cable.3. Space cable support eye bolts every 10 feet. Keep cable from becoming too slack, also not too taught as to pull out the cable end clevis.4. Shutdown controls should be wired through the motor control circuit, not directly to motor power.5. After applying power, actuate by pulling cable to check switch. This will ensure that there is not too much slack in the cable and that there are no obstructions in the cable or flag arm.
