Use Z1 and Z2 relays having the following specifications.
Operation coil
Rated voltage
:DC12V,DC24V
Power Consumption : 0.9W or less
(*1) Prepare a power supply separately according to the relay
being used. (DC12V or DC24V)
(*2) Always insert a diode on both ends of the relay coil.

No.2 Black ON/OFF
No.3 Brown Malfunction/normal
No.9 Red Common (External power supply) (*1)
(3) External input specifications
(A) For level signal
1 When the emergency stop/normal signal is selected, the status will change from normal to emergency stop when the
external input signal contact changes from OFF to ON, and will change from emergency stop to normal when the contact
changes from ON to OFF.
2 When the ON/OFF signal is selected, the status will change from OFF to ON when the external input signal contact
changes from OFF to ON, and will change from ON to OFF when the contact changes from ON to OFF.
(B) For pulse signal
1 Even if the ON signal is input during ON, the status will remain ON.
2 If the local remote controller is prohibited, the ON/OFF operation mode and temperature setting operations by the local
remote controller will be prohibited.
3 Set the pulse width (contact ON time) to 0.5 to 1 sec.
(4) Recommended circuit example
1
The contact relay, DC power source, extension cable, etc., must be prepared separately at the site.
2
The connection cable can be extended up to 10m. (Use a 0.3mm 2 or larger wire.)
3
Strip the extra cable near the connector, and securely insulate the exposed section with tape, etc.
2. External signal output function
* External signal output requires the external I/o adapter (Model: PAC-YG10HA-E) 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
1
“ON” signal and “Malfunction” signal will both be shown.
(3) Recommended circuit example
1 Each element will turn on while ON operation or a malfunction occurs.
2 The connection cable can be extended up to 10m.
3
The relays, lamps, diodes and extension cables, etc, must be prepared separately at the site.
