qWide range of supply voltage
qUser selectable input type through menu setup (ex: 0 to 5V,
0 to 10 V, 4 to 20 mA)
qWide ramp time range (0 to 99,5 sec)
qSimple control with analog input, locally supplied reference
voltage

qReverse polarity, command input protection
qLoad can be connected and disconnected live
The control electronics is intended for controlling of
proportional valves with one control solenoid. Its great
advantage is a miniature design in form of a socket for a
standardized DIN connector base. On the electronic
card’s top surface, two revolving selectors, a terminal
block for connecting of supply and control wires, and
three-position LED display are attached. The selector
marked as “SELECT” serves for selecting of parameters
for setting up. The second selector, marked as
“ADJUST”, serves for setting up of a desired value. In a
basic mode, the display shows an input/output
parameter value; conversely, in a setting mode, a
selected parameter abbreviation and the value being set
up are indicated. Setting up of an input control signal
selected type .

Set-up Procedure
1. At power up, the display will show either the output current signal or the input signal (Default display setting shows the
output signal). The decimal point will be flashing.
2. Rotate „SELECT“ to enter the set-up mode. Parameter abbreviation is indicated on the display
3. When you reach the setting you want to modify, rotate „ADJUST“ up or down to the desired value.
4. To modify another setting, rotate „SELECT“again and repeat..
5. The Driver is fully functional during the set-up procedure with any adjustments effective immediately.
6. In order to write the new settings in the memory and return to normal mode of operation, rotate „SELECT“ until the
display shows „SR“ and then rotate „ADJUST“ from 0 to 1 or wait for 100 seconds.
7. If you do not want to save the new settings you have just modified, you must disconnect the Driver form the power
supply before the end of the 100 seconds to restore precious settings.
8. After saving parameters to memory, the decimal point will be flashing and the Driver display will be back showing either
the output current signal or input signal depending on your „di“ selection.
9. To start over completely, you can restore the factory settings by rotating „SELECT“ to „rFP“ and then rotate „ADJUST“
up from 0 to 10 for the display to reset. (NOTE for Step 9: You may have to adjust your Input Signal Setting again if you
reset to factory settings.)
Attention:
Prior to setting up parameters, you must select proper Input Signal setting for your system.
Voltage signal from 0 to 10 V is standardly preset.
Applying improper Input Signal to wrong setting on the Driver may be damaging to Driver Unit and may
cause driver to fault to „Error“ Status mode .

ERROR DETECTION STATE, Short Circuit, Reverse polarity protection and detection
- Error 0 - No Errors
- Error 1 - Overcurrent in driver likely due to short circuit in Solenoid
- Error 2 - Current exceeding 20 mA in „4 to 20mA“ input mode
CLr CLEAR ERROR, Clears Driver of Error State
NOTE: When adjusting the HI and LO parameters, note the HI parameter value cannot be adjusted below the LO
parameter value as well the LO parameter value cannot exceed the HI parameter value.
