® ATD 50 Actuator Operating Instructions 2.1 Correct Use ® The ATD 50 Actuator is designed for operating automatic doors on machine tools and industrial equipment. It is intended to automatically open and close doors, detect obstructions, and hold the door when closed. Vertical doors must be ® installed using a counter-weight system since the ATD 50 Actuator is not intended to lift or hold the weight of a door. ® Any other use for the ATD 50 Actuator is the judgement and risk of the installer.

® ATD 50 Actuator Operating Instructions 6 Check List for Functional Tests (cont.) TEST 3: OPTIMIZE MOVEMENTS ACTION: Operate the door for two (2) complete open and close movements. EXPECTED BEHAVIOR: Door should open and close normally. The microprocessor measures the torque and sets the internal speed and torque references. These references are used as safety thresholds for detecting obstructions. NOTE: The safety reversing function is not active during the first two (2) open and close cycl
