3 - 25 CONTROLLER
Controller
(A) For level signal
4). Recommended circuit example
The contact relay, DC power source, extension cable, etc., must be prepared separately at the site.
The connection cable can be extended up to 10m (32 ft). (Use a 0.3mm
2 (AWG 22) or larger wire.)
Strip the extra cable near the connector, and securely insulate the exposed section with tape, etc.
CN5 Lead wire Details of each terminal
No.1 Green Common (External ground)
No.2 Black ON/OFF*
No.3 Brown Malfunction/normal
(2). External signal output function
1). External output
When one or more air conditioners are running, the " ON " signal will be output and if a malfunction occurs in one or more air
conditioners, the " Malfunction " signal will be output.
2). External output specifications
3). Recommended circuit example
Each element will turn on while ON operation or a malfunction occurs.
The connection cable can be extended up to 10m (32 ft).
The relays, lamps, diodes and extension cables, etc, must be prepared separately at the site.
* To use the external signal input, an external I/O adapter (PAC-YG10HA; sold separately) and an external power supply are required.
