3.2.2 Digital Inputs and Relay Outputs
The digital inputs and relay outputs indicate that a signal from an input/output
device has been received.
Digital Inputs – Each indicates that the input has been activated by a machine
action. When active, the box next to the input will be bright green in color.
E-stop – Indicates that an emergency stop switch has been pressed. The E-stop
is normally closed and the box next to the E-stop input is bright green. When the
button is pressed, the E-stop input indicator will appear dark.
Relay Outputs – Each indicates that the output relay has been activated by the
controller. When active, the box next to the output will be bright red in color.
Inputs and outputs are assigned at the factory to indicate specific actions, and
will vary with the compressor model. Typical factory assignments of inputs and
outputs are as follows:
