Crawford Cdm9 950 Installation Manual May 2026

ECS 950

The Crawford CDM9 operator, often paired with the control unit, is a high-performance drive for industrial overhead sectional doors. This manual content covers technical specifications, mechanical assembly, and initial setup procedures. 1. Technical Specifications

• Verify door type and weight, opening width and height, tracks and springs condition, counterbalance capacity, and hinge/roller condition; these affect operator sizing and settings.
• Confirm mounting surface: header, wall, or frame must be structurally sound and able to support operator weight and applied forces.
• Ensure sufficient clearance for operator body, control box, conduit, and maintenance access. Check access for manual release and emergency features.
• Electrical supply: confirm available supply voltage and phase (single- or three-phase) and fuse/breaker sizing per nameplate. Confirm control circuit supply (often 24 VDC or 24 VAC) if separate.
• Environmental factors: indoor/outdoor location, ambient temperature range, and exposure to moisture or corrosive atmospheres—select weatherproofing or enclosures as required.

• Install and wire safety edges on bottom edge per position indicated. Test edge activation stops/reverses travel.
• Mount and align photoelectric sensors at required heights and angles; test obstruction detection.
• Ensure loop detectors or vehicle sensors are installed and tested.
• Install warning signage and audible/visual alarms if required.

Installation Requirements

• Ensure compliance with applicable local standards for powered doors and safety (examples: ANSI A156.10/A156.19, EN 12453/EN 16005, regional electrical codes). Where a certified inspector or statutory declarations are required, arrange for inspection prior to operation.

• Type K thermocouple: Set SEnS to K
• Pt100 RTD: Set SEnS to Pt1
• 4-20mA input: Set SEnS to Lin and scale Lin.L (4mA = low value) and Lin.H (20mA = high value).

• Connect the PE terminal directly to the system ground busbar with an impedance of <0.1 Ω.
• Do not daisy-chain grounds between multiple CDM9 950 units.
