(c) Emergency stop signal processing
When the external signal input is used to stop operation, the remote stop signal is input at CnT or CnTA. This input is
effective only on indoor units which can receive it. Where two or more indoor units are controlled with a wired remote
control on the system, on which the external input is set at the "Same operation on all units", if the stop signal is input at
CnT on an indoor unit, all units connected to the wired remote control can be controlled collectively. This emergency stop
signal is used to stop in emergencies all indoor units connected to the same outdoor unit.
(i) The emergency stop control is enabled by selecting the "Valid" for the emergency stop control on the wired remote
control.
(ii) If the emergency stop [E-63] is received from the outdoor unit, it is transmitted to the wired remote control so that all
indoor units are stopped.
(18) Operation permission/prohibition
(In case of adopting card key switches or commercially available timers)
When the indoor function setting of wired remote control for "Operation permission/prohibition" is changed from "Invalid
(Factory default)" to " Valid", following control becomes effective.

*1 Only the "LEVEL INPUT" is acceptable for external input, however when the indoor function setting of
"Level input (Factory default)" or "Pulse input" is selected by the function for "External input" of the wired remote
control, operation status will be changed as follows.
In case of "Level input" setting
Unit operation from the wired
remote control becomes
*(1) In case that "Operation permission/prohibition mode" setting is "Valid" and "External input" setting is "Level
input (Factory default)";
①
When card key switch is ON (CnT-6 or CnTA ON: Operation permission), start/stop operation of the unit
from the wired remote control becomes available.
②
When card key switch is OFF (CnT-6 or CnTA OFF: Operation prohibition), the unit stops operation in
conjunction with OFF signal, and start/stop operation of the unit from the wired remote control becomes not
unavailable.
*(2) In case that "Operation permission/prohibition mode" setting is "Valid" and "External input" setting is "Pulse
input (Local setting)";
①
When card key switch is ON (Operation permission), the unit starts operation in conjunction with ON signal.
and also start/stop operation of the unit from the wired remote control becomes available.
②
When card key switch is OFF (Operation prohibition), the unit stops operation in conjunction with OFF signal, and
start/stop operation of the unit from the wired remote control becomes unavailable.
(3) This function is invalid only at "Center mode" setting done by central control.
