Remedy
"Overheat"
Working temperature is too
high. Valve is in temperature
shut-off.
Switch off the valve, let it cool
down and restart. Reduce ambi-
ent temperature or temperature
of medium.
"Cable break"
Cable break setpoint input
Check connection to setpoint
generator.
Replace supply cable.
"Oscillation"
Continuous vibration detected.
Select another parameter set for
application.
"No air supply"
No input pressure p1.
Setpoint value not reached.
Increase input pressure p1.
Maintain permissible maximum
operating pressure
è
"DC-supply low"
Supply voltage is too low.
Increase supply voltage.
"DC-supply high"
Supply voltage is too high.
Reduce supply voltage.
"Heat protection"
Temperature critical, power
reduction active
Reduce ambient temperature or
temperature of medium. Ensure
sufficient compressed air sup-
ply.
"High deviation"
Setpoint value not reached.
Input pressure p1 is too low.
Air consumption at the working
port is too high.
Increase input pressure p1.
Maintain permissible maximum
operating pressure
è
"Setpoint high"
Analogue setpoint value is too
high.
Correct setpoint value.
