Values for CC-8251G-90 are from datasheet CT/TDS/01; the other three follow the Channeltech catalogue, with full datasheets issued on request.
Not sure which? Three questions and the coil count.
Answer what is in the car and how tall the shaft is; then put in the travel height and we size the job in 90 m coil pairs.
Choosing — questions
How do I know if the lift camera is IP or HD?
If the camera connects to an NVR with an RJ45 plug it is IP. If it connects to a DVR with a BNC connector it is HD or analog. The camera's label usually says IP / PoE, or HD-TVI / AHD / CVI.
What travel height do I enter?
The distance the car travels from the lowest to the highest landing, not the building height. The lift company has it on the drawing; roughly 3 m per floor for residential buildings.
Why 90 m coil pairs?
Lift jobs consume cable in pairs — two lifts in a bank, or a run and its spare — so Channeltech supplies matched 90 m + 90 m coils. One pair typically serves two lifts.
