(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 shown.
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 (32ft).
The relays, lamps, diodes and extension cables, etc, must be prepared separately at the site.
Use Z1 and Z2 relays having the following specifications.
Operation coil
Rated voltage :12VDC,24VDC
Power Consumption : 0.9W or less
( 1)Prepare a power supply separately according to the
relay being used. (12VDC or 24VDC)
( 2)Always insert a diode on both ends of the relay coil.
" ON" signal and " Malfunction" signal will
both be output.
External signal output requires the external I/o adapter (Model: PAC-YG10HA) sold separately.
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.
