MANUAL ADJUSTMENT

1.3.1

Manual operation

After an interruption in the power supply, press both arrow buttons located beneath the display during power up
to switch to the manual mode. This 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 output value, press the right arrow button or UP arrow
to increase the output value. 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.
1.3.2

Auto-Adapt

This function should only be activated when the module is set to current control. In the event of an interruption in
the power supply, the module will enter into the Auto-Adapt mode by pressing the ADAPT button underneath the
display when switching on the power supply. The Auto-Adapt mode is indicated by the letters „AdA" in the display.
The valve output is supplied with power for 3 seconds. After this period, the maximum current is measured and
displayed for 3 seconds. The module then switches back to the normal operating mode.
Caution: When measuring the maximum current, the output is activated with the supply voltage. The module can
be damaged when using solenoid coils that require a supply voltage of more than 2000 mA.
All parameters must be read, copied and written again on return to the normal operating mode from the Auto-
Adapt mode in order to update max. current, setpoint offset and setpoint span.

OPERATING MODES

Shut-off: If the setpoint falls below 0.5 %, the valve is switched off.
Overtemperature: If the temperature of the internal control electronics exceeds 120°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 valve is switched off
and fully exhausted. The red LED lights up constantly to indicate undervoltage or flashes to indicate overvoltage.
Autosafe: When autosafe is activated, the pulse width signal for the coil current is limited to a duty cycle of
70% ED after 20 seconds. Every 4 seconds, the duty cycle is switched to 100% ED for 0.5 seconds. The yellow
LED flashes.

ELECTRICAL CONNECTION

1) The valve must only be supplied with 24V DC at a tolerance of +10%/-10% (12 V: + 15%/-5%) and a max. ripple of 10%
(no supply via diode bridge). Overvoltage or a ripple rate exceeding these tolerances can damage the electronics.
2) The max. current at the digital output is 500 mA (PNP output). The output is protected against short circuit and overload.
3) If a relay (inductive load) is connected to the digital output, a freewheel diode or a varistor must be used.
4) A shielded cable must be used for protection against interference and EMC.
5) The valve body must be grounded with the earthing terminal (pin 3).
