(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.
