Malfunction

Possible cause

Remedy

Device does not respond

No supply voltage, LED [power]
off.

Check the connection of the
supply voltage 24 V DC.

No data communication.

Check control unit.

Check connection.

Flow rate too low

Restriction of the flow cross
section by connection tech-
nology.

Use alternative connections.

Pressure rise too slow

Large cylinder volume and long
tube length.

Select another parameter set.

Pressure constant despite
modified setpoint specification

Break in the electrical con-
necting cable.

Replace supply cable.

Supply pressure P1 too low.

Increase supply pressure.

Manual selection of parameter
sets with the [UP] and [DOWN]
keys on the device is not pos-
sible

Voltage is applied at digital
inputs D1 and D2.

Apply 0 V DC at digital inputs
D1 and D2.
