8.3

Starting and Stopping the Compressor Unit

Do not start and stop the compressor package with the main discon-
nect switch. The compressor must always be switched ON and OFF
with keys (1) and (2).

To turn the compressor ON (local):

Switch on the main disconnect switch.

The controller carries out a self---test. The self---test sequence is visible in the display (12).
Afterwards, the green LED (16) illuminates permanently.

Press the ON key (1) --- LED (19) illuminates.

The compressor status is indicated by LEDs (17) and (18):

If LED (19) is illuminated and both LEDs (17) and (18) are extinguished
the compressor package is at standstill but on duty.

The compressor package can start at any moment.

To turn the compressor OFF (local):

Press the OFF key (2) --- LED (19) extinguishes.

Lock the main disconnect in the ”off” position in accordance with applicable lock out/
tag out procedures (example: OSHA CFR 29 § 1910.147) to ensure the compressor
does not restart.

See chapter 2.3 for the main disconnect switch.

8.4

Acknowledgement of Alarms

If an alarm occurs the compressor package is shut down immediately and the red
LED (13) on SIGMA CONTROL flashes.

The bottom line in the display (12) shows the actual fault causing the alarm.
A list of alarms that may occur during operation is included in the SIGMA CONTROL
service manual.

Remove the fault.

Acknowledge alarm with the reset key (11) --- LED (13) extinguishes.

The compressor package is now ready to start again.

If the compressor was shut down with the EMERGENCY STOP push-
button, then reset by rotating the latched pushbutton in the direction of
the arrow before acknowledging the alarm.
