8.5.2 Setting pressure parameters
8.5.2.1 Setting the network nominal pressure: pA and pB
The pressure parameters can only be set within certain limits:
Rated machine pressure ≥ SP: pA /pB ≥ Min. cut-in pressure* + switching differential
Tab. 56 Setting limits for the network nominal pressure (* Cut-in pressure min)
The machine switches to LOAD under the following condition:
Network pressure ≤ SP: pA /pB + switching differential
Tab. 57 Pressure condition for LOAD
The machine switches to IDLE under the following conditions
12)
:
Network pressure = Network nominal pressure
