KAESER ESD.2C - Adjusting Pressure Rise Pe; Adjusting the Value for “System Pressure Low”

3. Press «Enter» to switch into setting mode.
The 116 psi parameter flashes.
4. Use «UP» or «DOWN» to adjust the system setpoint pressure pA.
5. Press «Enter» to accept the setting.
6. Adjust the switching differential in the same way.
7. Adjust the pB and the switching differential in the same manner, if necessary.
8. Press «Esc» repeatedly to return to the Main Menu.
Result The settings for the system setpoint pressure pA and pB are adjusted.
7.4.2.2 Adjusting the value for “System pressure low”
If the system pressure falls to the sys.press.low value, SIGMA CONTROL 2 will display a warning
message for the system pressure being too low.
The switching differential influences the pressure at which the message can be acknowledged or
the optionally activated output will again switch:
Message Output
73 psi message appears Active
80 psi messages disappears Inactive
Tab. 56 Example: Activated output

7.4.2.3 Adjusting pressure rise pE
The value for pressure rise pE serves as a safety limit value when the machine is externally con‐
trolled. When the system set pressure reaches the value pE (for example, when the external con‐
trol functions incorrectly) the machine switches to IDLE.
The warning message ext.load signal? is displayed.
