External input signal setting
Do not use external input. (Factory setting)
Emergency stop/Normal operation signal
(level signal)
ON/OFF signal (level signal)
ON/OFF and Prohibit/Permit remote
controller operation signal (pulse signal)
Notes
-
When the units are not operating after receiving an emergency stop signal,
the ON/OFF operation from the local remote controller will not be allowed,
and the ON/OFF and Prohibit/Permit settings on the Touch Controller
cannot be changed. Timer operation will not function.
ON/OFF operation from the local remote controller will not be allowed, and
the ON/OFF and Prohibit/Permit settings on the Touch Controller cannot
be changed. Timer operation will not function.
The ON-signal pulse width should be set to a value between 0.2 and 1
seconds.
6 Using external input/output
1. External signal input (CN2)
*To use external input, an external input/output adapter (PAC-YT41HAA; sold separately) is required.
(1) External input
Using external dry contact signals, the following operation of all air conditioning units can be controlled from the Touch Controller:
Emergency stop/Normal operation, ON/OFF, Permit/Prohibit local remote controller operation. These settings are made on the
External Input Settings on the Initial Settings screen that is accessible from the Service Menu screen. (Refer to Chapter 3 in the Initial
Setting Manual.)
(3) External input specifications
(A) Level signal
• tIf the type of signal assigned to the external input contact is "Emergency/Normal," the units in normal operation will stop
when
the signal input changes from OFF to ON. Conversely, the units that are stopped will resume normal operation when the signal
changes from ON to OFF. After the emergency stop is reset, the original operating status of each air conditioning unit will not be
automatically restored. The air conditioning units must be started up manually.
•
If the type of signal assigned to the external input contact is
"ON/OFF,"
the units that are stopped will start operation after the
input signal changes from OFF to ON. Conversely, the units that are in operation will stop after the input signal changes from
ON to OFF.
(B) Pulse signal
• If the incoming signal is the same as the signal that is currently being received, no status change will occur.
•
If local remote controller operation is prohibited, ON/OFF status, operation mode, or temperature setting cannot be changed and
filter sign cannot be reset from the remote controller.
• The ON-signal pulse width should be set to a value between 0.2 and 1 seconds.
