Before powering up, manually disengage the door and position it roughly 1.5 meters above the ground.
Link the motor to the Crawford control cabinet using the provided system cables. Most CDM9 units use "plug-and-play" connectors to minimize wiring errors.
Always leave a small gap at the top to prevent the motor from straining against the stops. 4. Safety and Force Calibration This is the most critical step for workplace safety. Force Sensing:
Align the internal keyway of the CDM9 950 hollow shaft with the key on the door shaft.

The Crawford CDM9 950 is a heavy-duty, automated industrial door operator designed for reliability and safety. Proper installation ensures optimal performance and extends the lifespan of your industrial door system. This comprehensive guide details the step-by-step procedure for installing, wiring, and commissioning the Crawford CDM9 950 system based on factory manual standards. 1. Pre-Installation and Safety Requirements
: Use the Up/Down buttons in "hold-to-run" mode to move the door until the bottom rubber sealing edge aligns perfectly with your 1 meter mark. Before powering up, manually disengage the door and
Test all safety devices. Ensure the door immediately reverses when the safety edge or photo-eye is triggered during closing.
Verify the door's manual balance by releasing the emergency manual override chain/disconnect and lifting the door by hand.
If equipped with a emergency hand chain, ensure the chain hangs freely without tangling in moving parts.
The manual specifies a panel cutout of 92x92 mm (1/4 DIN standard). However, the depth behind the panel requires 120 mm clearance for wiring and cooling. Use the supplied mounting bracket clips—do not over-torque them, as this warps the front bezel and compromises the IP54 front seal. Always leave a small gap at the top
Mark a "1-meter position" on the door frame/track to serve as a visual calibration point during the limit setting. Electrical & Control Setup
: Route the pass-door interlock switches and safety optical edges (OSE) back to the board. Low voltage neutral terminates on block X1:7 . Step 4: System Initialization & Commissioning
By carefully following this manual framework, your will provide efficient, safe, and continuous operation. For complex configurations or structural alterations, always consult an authorized Crawford service technician.
