After an interruption in the power supply, press both arrow buttons located beneath the display during power up to
switch to the manual mode. The operating mode is indicated by the letters “H n d” in the display.
The "H n d" display disappears when the arrow buttons are released.
Press the left arrow button or DOWN arrow to reduce the outlet pressure, press the right arrow button or UP arrow to
increase the outlet pressure. The yellow LED is on permanently during manual mode.
Exit this operating mode by pressing both arrow buttons simultaneously or by turning off the power supply for a short
time.
1.4 Operating Modes
Shut-off:
If the command signal 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
and the green LED starts to flash.
Undervoltage / overvoltage:
If the supply voltage is less than 20 V or more than 30 V, the coil current is switched off and the valve is fully exhaust-
ed. The red LED lights up constantly to indicate undervoltage or flashes to indicate overvoltage.
Autosafe:
If the coil current exceeds 1000 mA (DN8) or 560 mA (DN4) for more than 20 seconds, the output current is limited to
max. 70% every 4 seconds to prevent the valve from overheating. The yellow LED flashes.
