7.7 Measuring the air receiver charging time
Measuring the time the compressor takes to fill the air receiver when new can be useful in checking
the machine's performance at a later date.
Precondition Machine at operating temperature.
1. Close the shut-off valve to the air main.
2. Switch on the power supply disconnecting device.
3. Measure the air receiver charging time.
4. Enter the charging time and machine model in the table.
Machine model
Receiver charging time from 3 – 14.5 bar [min / s]
Tab. 28 Air receiver charging time
7.8 Setting network pressure
The network pressure (working pressure) is set at the factory.
A pressure adjustment is possible to suit individual operating conditions.
The pressure setting can only be adjusted if a pressure switch is fitted and under pressure.
Maximum pressure differential: 20% = (3.2 bar) of the maximum operating pressure of the air
receiver.
