[External signal input function]
Using external contact signals (12 or 24 VDC), the following collective operations for all connected air conditioning units can
be controlled: Emergency stop, ON/OFF operation, and Prohibit/Permit local remote controller operation.
3. External input/output usage
To use the external signal input, an external I/O adapter (PAC-YG10HA-E; sold separately) and an external power supply are required.
NOTE:
When using the AE-200E connected with the AE-50E/EW-50E, use external input/output function of each AE-200E/AE-50E/EW-50E.

Setting mode
Description
[Demand (Level signal)/Not in use]
(Factory setting)
Select this mode when inputting a demand level using a level signal, or when not
using an external signal input function.
A
demand signal of four different levels will be input.
[Emergency Stop (Level signal)]
Using a level signal, all the air conditioning units connected to the AE-200E or AE-50E
/EW-50E will be stopped collectively in an emergency. During an emergency stop, the
ON/OFF operation from the local remote controllers will be prohibited, and the ON/OFF
operation and Prohibit/Permit settings on the AE-200E or AE-50E/EW-50E will be
prohibited. A demand signal of three different levels will be input.
[ON/OFF (Level signal)]
Using a level signal, all the air conditioning units connected to the AE-200E or AE-50E
/EW-50E will be run or stopped collectively. The ON/OFF operation from the local
remote controllers will be prohibited, and the ON/OFF operation and Prohibit/Permit
settings on the AE-200E or AE-50E/EW-50E will be prohibited. Scheduled operations
will not be performed.
[ON/OFF/Prohibit/Permit (Pulse signal)]
Using a pulse signal, all the air conditioning units connected to the AE-200E or AE-50E
/EW-50E will be run or stopped collectively, or the operation from the local remote
controllers will be prohibited or permitted collectively
.
*
General equipment connected via a DIDO controller (PAC-YG66DCA) cannot be collectively run or stopped by using the external signal input
function unless [Emergency Stop (Level signal)] is selected and relevant switches on the DIDO controller are set.
*
The external input function cannot be used on HWHP (CAHV) units.
