2.6.5 Signal functions
The compressor can be controlled in two different operating modes, Momentary operating
mode and Alternate operating mode. You can neither use both operating modes at the
same time, nor switch one operating mode to the other depending on the situations.
Ensure to choose one of the operating modes and connect signal lines needed for the
operating mode you chose. Do not connect signal lines for the operating mode that you
will not use. Decide the operating mode depending on the application of the equipment
side. Momentary operating mode is equivalent to operate by using pushing button switch,
and Alternate operating mode is equivalent to operate by using selector switch.
Alternate operating mode is easier and simpler for use in general.
Selecting operating mode
1. Momentary operating mode
2. Alternate operating mode
Default operating mode is either Momentary operating mode or Alternate operating mode.
The operating mode is switched automatically.The operating mode is determined by
recognizing into which input pin the operation command of the compressor has entered
after turning on the power supply.
Once the operating mode is selected, the mode will be kept until the compressor is turned
off.
