10 Malfunctions
Status of the LED displays
Cause Green LED [power] Red LED [error]
– Undervoltage or overvoltage
of the setpoint value
on on
– Hardware error
– Overvoltage (> 30 V)
– Internal temperature too
high
on flashes
– Undervoltage (< 18 V) off off

Fault clearance
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.
