3. System remote controller
2. External input/output usage
NOTE : When using the AG-150A connected with the expansion controller, use external input/output function of the expansion controller.
(1). External signal input function
To use the external signal input, an external I/O adapter (PAC-YG10HA; sold separately) and an external power supply are required.
1). External input
Emergency stop/normal, ON/OFF and prohibit/permit of local remote controller operation can be controlled for all air
conditioners being controlled by using a voltage (12VDC or 24VDC) contact signal from an external source.
(Select with the function select setting.)

* DIDO controller (PAC-YG66DCA) cannot be collectively run or stopped by using the external input function. But when
[Emergency stop (Level signal)] is selected, DIDO controller (PAC-YG66DCA) can be collectively stopped by setting the
appropriate switches on the DIDO controller.

(A) For level signal
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. Air conditioning units that came to an emergency stop will remain stopped after
the emergency stop is cancelled. Manually start up each unit to restore the previous operation.
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
Even if the ON signal is input during ON, the status will remain ON.
If the local remote controller is prohibited, the ON/OFF operation mode and temperature setting operations by the
local remote controller will be prohibited.
Set the pulse width (contact ON time) to 0.5 to 1 sec.
