External Input/Output Usage; External Signal Input Function - Mitsubishi Electric AG-150A-A Installation Manual

11 External input/output usage

1. External signal input function

* External signal input requires the external I/O adapter (PAC-YG10HA) sold separately.
NOTES
* When using a PAC-YG50ECA Expansion controller, connect the external input/output adapter to the external input terminal on
the Expansion controller, not to the AG-150A.
* Make necessary settings for each Expansion controller from the AG-150A on the Network Settings window (external input
settings).
(1) External input
Emergency stop/normal, run/stop and prohibit/enable operation of local remote controllers can be controlled for all air conditioners by
using a voltage (12VDC or 24VDC) contact signal from an external source. (Select with an initial settings screen.)

* DIDO controller (PAC-YG66DCA) cannot be collectively run or stopped by using the external input function.
But when [Perform emergency stop/normal with 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
1 When the emergency stop/normal signal is selected, the status will switch 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 are stopped will remain off after the emergency stop is cancelled.
Start up each indoor unit to manually restore the previous operation.
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 local remote controller operation is prohibited, the ON/OFF operation mode, temperature setting operations, and filter
reset from the local remote controller will be prohibited.
3 Set the pulse width (contact ON time) to 0.5 to 1 sec.
The local remote controller ON/OFF operation, the controller ON/OFF operation,
and prohibit/enable change operation will be prohibited during emergency stop.
Timer operation will also be prohibited.
The local remote controller ON/OFF operation, the controller ON/OFF operation,
and prohibit/enable change operation will be prohibited. Timer operation will also
be prohibited.
Set the pulse width while the contact is ON to 0.5 to 1 second.
