7.9 Setting the set point pressure
The system pressure pA is factory set to the highest possible value.
Adjustment is necessary for individual operating conditions.
Do not set the set point pressure of the machine higher than the maximum working pressure
of the compressed 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 set point pressure as described in the SIGMA CONTROL 2 operating manual.
