5. Press the «ON» key.
The green LED
Machine ON lights and the machine runs in IDLE. This ensures that cooling oil
is distributed throughout the machine.
6. After allowing the machine to IDLE for at least 1 minute:
Press the «LOAD/IDLE» key.
The machine switches to LOAD and delivers compressed air.
➤ Keep an eye on the machine during the first few hours of operation to ensure that it is
operating correctly.
➤ After the first 50 operating hours, all screw-type electrical connections should be checked
and tightened if necessary.
7.9 Setting the Setpoint Pressure
The setpoint pressure p1 is factory set to the highest possible value.
Adjustment is necessary for individual operating conditions.
Do not set the setpoint pressure of the machine higher than the maximum working pressure of
the air system.
The machine may not toggle more than twice per minute between LOAD and IDLE.
To reduce the cycling (toggling) frequency:
➤ Increase the difference between cut-in and cut-out pressure.
➤ Add a larger air receiver downstream to increase buffer capacity.
➤ Set the setpoint pressure as described in the SIGMA CONTROL operating instructions.
7.10 Changing the display language
The controller can display text messages in several languages. The display language can be changed
first during initial start-up.
A label explains how this is done with the help of icons.
