3.5 Emergency stop button
Control panel
Description
In case of emergency, press button (S2) to stop the compressor immediately.
Using the emergency stop breaks the circuit to:
• the variable speed drive unit of the drive motor.
• on air-cooled compressors, the variable speed drive unit of the fan motors.
• on Full-Feature compressors, the dryer fan motor.
• on GA (W) VSD Full-Feature compressors, the variable speed drive unit of the compressor motor of the
dryer.
By using the emergency stop, solenoid valve (Y2) will open the blow-off port, resulting in depressurisation
of the air receiver.
At the occurrence of an emergency stop, the compressor element is stopped immediately and the solenoid
valve will be deactivated by Elektronikon ® regulator. No unload status is reached. The check valve prevents
oil flow back from reversed rotation of the compressor element.
Before starting any maintenance or repairs, wait until the compressor has
stopped and open the isolating switch (customer's installation) to switch off the
voltage to the compressor.
Close the air outlet valve and open the manual condensate drain valves to
depressurize the air system.
Apply all relevant Safety precautions.
