1.3 OPERATING MODES
Shut-off:
If the setpoint falls below 0.5 %, the coil current is switched off and the valve is fully exhausted.
Overtemperature:
If the temperature of the internal control electronics exceeds 100°C, the operating mode is switched to AUTOSAFE.
Undervoltage / overvoltage:
If the supply voltage is less than 18 V or more than 30 V, the coil current is switched off and the valve is fully
exhausted..
Autosafe:
If the coil current exceeds a certain value, dependent on the mechanics, for more than 20 seconds, the output
current is limited to max. 70% to prevent the valve from overheating.
