4). Recommended circuit example
(A) For level signal
This unit
(B) For pulse signal
This unit
The relays and extension cables, etc. must be prepared separately at the site.
Use a no-voltage contact and minute load relay (minimum application load 5VDC-1mA).
The length of the connection cable extension should not exceed 10 m (32 ft). (Use a cable of 0.3 mm
Cut of the cable not being used close the connector and properly insulate the cut off ends with tape or the like.
(2). External signal output function
External signal output requires the external I/o adapter (Model: PAC-YT41HAA) sold separately.
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 shown.
2). External output specifications

Each element will turn on while ON operation or a malfunction occurs.
The connection cable can be extended up to 10m (32ft).
The relays, lamps, diodes and extension cables, etc, must be prepared separately at the site.
