Before lifting the unit, the drive shaft of the door must be inspected for burrs or damage. The CDM9 is typically mounted directly onto the door shaft (hollow shaft drive). Alignment:
The unit must be level. Even a slight tilt can lead to premature wear on the internal gears or the coupling.
Use the torque bracket provided. This prevents the motor from rotating around the shaft when it starts up. Without a properly secured torque arm, the motor will eventually tear itself away from the wall or damage the wiring. 2. Electrical Connections Comprehensive Guide to Installing the Crawford CDM9 950:
The CDM9 system usually pairs with a 950-series control box. Power Supply:
Standard installations require a 230V AC or 400V 3-phase connection, depending on the specific model variant. Plug-and-Play:
Modern Crawford units use system-specific connectors. Ensure the motor cable and the encoder cable (which tells the brain where the door is) are seated firmly and routed away from moving parts. 3. Setting the Limit Switches
The 950 system uses a digital encoder rather than old-school mechanical cams. This means you set the "Open" and "Closed" positions at the control panel: Floor Level:
Jog the door down until it touches the floor, then save the position. Upper Limit:
Jog it up until the door is clear of the opening but not hitting the physical track buffers. Safety Buffer:
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:
The CDM9 has an integrated force-sensing feature. During the first few cycles, the controller "learns" the weight of the door. If the door hits an obstruction, the increase in resistance triggers an immediate stop or reversal. Safety Edge:
Ensure the bottom profile sensor (optical or pneumatic) is wired correctly. Test it by placing an object (like a cardboard box) in the path to ensure the door reverses on contact. 5. Maintenance Handover The final stage of installation is testing the emergency release
