Behaviour of P58 (Actual Value Increase) and P59 (Actual Value Decrease):
• if P58 (Actual Value Increase) = P59 (Actual Value Decrease) → Pressure constant,
independent of how many pumps are in operation.
• if P58 (Actual Value Increase) > P59 (Actual Value Decrease) → Pressure rises when assist
pump switches on.
• if P58 (Actual Value Increase) < P59 (Actual Value Decrease) → Pressure decreases when
assist pump switches on.
