The installation manual provides a comprehensive framework for setup, maintenance, and technical troubleshooting. Manual Highlights & Technical Specifications

The installation guide covers several variants of the operator, each designed for specific door weights and performance needs: Hurð ehf. : Maximum door weight of , with an opening/closing speed of CDM9 HD (Heavy Duty) : Designed for doors between 400 kg and 800 kg , with a slightly slower speed of : High-speed variant supporting up to with an opening speed of Operating Conditions

for protection against dust and water, and functional in temperatures from -20 °C to +55 °C Key Installation Steps The manual outlines a specific mechanical assembly process: Hurð ehf. Drive Unit Assembly

: Requires fitting stop rings and adapters onto the pivot before pushing on the drive unit. Torque Bar Mounting

: Mounting the torque bar with a rubber damper between the bar and the console to manage mechanical stress. Positioning : The operator must be installed at a height of at least above the floor for safety compliance. Troubleshooting & Service Tools A significant portion of the documentation focuses on the control system and its serviceability: Service Tool Integration

: Technicians use a dedicated service tool to navigate menus (e.g., using SW1 and SW2 buttons) to view error logs or reset service timers. Common Diagnostics

: The manual provides fault charts for issues like "door not starting" or "reversing during closure," often directing users to check voltages between specific pins (e.g., X1:7 and X1:5). Safety Features : Includes detailed instructions for the Optical Safety Edge (OSE)

system, which uses photocells and a spiral cable to detect obstructions. Reference Resources

The Crawford CDM9 operator, typically paired with the ECS 950 control unit, is designed for overhead sectional doors and must be installed at a height of at least 2.5 meters above the floor. 1. Mechanical Installation Assembling the Drive:

Place the first stop ring onto the pivot, followed by the adapter. crawford cdm9 950 installation manual top

Push the drive unit onto the shaft and fit the second stop ring.

Mount the torque bar onto the mechanical unit, ensuring the rubber damper is placed between the torque bar and the console. Adjust the drive position and tighten all screws. 2. Setup and Programming (SW1 Method)

Initial Positioning: Disengage the door and manually place it roughly 1.5 meters above the ground, then re-engage the operator. Calibration:

Turn on the power; note that power must be cycled (OFF-ON) before starting installation. Mark a position 1 meter above the floor on the door track. Set the SW1 switch on the control board to ON.

Press and hold the "Down" button until the door’s bottom rubber edge reaches your 1m mark.

For doors with impulse operation, briefly actuate the installation device; the door should move down, reverse against the floor or safety device, and then open fully to find its upper limit. Turn SW1 to OFF once the limits are learned. 3. Electrical & Troubleshooting

Safety Devices: External buttons or switches must be mounted at a minimum height of 1.5 m and within line of sight of the door.

Wiring: The control unit uses 24 VAC for input terminals (X8). If no function is working, verify that there is 24 VAC between X8 terminals and terminal 15.

Service: A "Service lamp" on the 950 control box indicates required maintenance or a fault that may requires the ECS 950 Service Tool for diagnosis.
