and remove all power from the outputs. This will shut down
the compressor motor and all control power (120v) to the
compressor auxiliary systems such as the oil pump and liq-
uid injection solenoid. THE EMERGENCY STOP BUTTON
IS FOR EMERGENCY SHUTDOWN SITUATIONS ONLY
and MUST NOT BE USED TO ROUTINELY SHUT OFF
THE COMPRESSOR.
The microprocessor hardware contains an internal watch-
dog circuit. If the microprocessor should fail, this circuit will
disable (turn off) all outputs.
The RXF compressor is controlled by a state-of-the-art mi-
croprocessor control system. The microprocessor continu-
ously monitors the compressor unit’s condition and opera-
tion. The microprocessor also directs instructions to the vari-
ous compressor unit subsystems.
The microprocessor has a membrane switch keyboard.
Pressing the keyboard in the area outlined as a key will cause
that function to be recognized by the microprocessor. The
keyboard has 32 membrane-type keys.
In addition to the keyboard, there is an emergency stop but-
ton. Pushing the emergency stop will bypass the computer
