– Valve slide sticks
– Temperature of the solenoid coil ≥ 100 °C

Reset fault
1. Rectify the cause of the error.
2. Acknowledge error (set DIn1 to 1).
If the error cannot be acknowledged via DIn1, switch supply voltage off and back
on again.
è
The driver is switched back on via a rising edge at the digital input. The flow
control valve controls to the specified flow setpoint value again.

Depending on the deviation of the ambient temperature from the standard
value (20 °C), the actual flow of the valve differs from the measured or
specified flow (
