10. External input/output
To reduce the risk of injury, do not touch the burrs of the knockout holes.
To use external input/output, a separately-sold external input/output adapter (PAC-YG10HA-E) is required.
When connecting an external input/output adapter (PAC-YG10HA-E), cut out the CN5 knockout hole. (Refer to
section 2-1 “Part names” for the location of CN5.)
Note
● When using AE-50, connect the external input/output adapter to each AE-200/AE-50. (External input signal to AE-200 cannot
perform the collective operations (e.g., emergency stop) for AE-50 systems.)
● Use caution not to damage the circuit board with tools when cutting out the knockout hole.
● Set the [External Input Setting] setting for each AE-200/AE-50 on the [Network] screen.
10-1. 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.
(1) External signal input function setting
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-200 or AE-50
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-200 or AE-50 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-200 or AE-50
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-200 or AE-50 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-200 or AE-50
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.
