18.1.4 Configuration of current interface
The VSD is controlled via a current interface which can be switched from 0...20 mA to
4...20 mA, or vice versa.
Parameter:
Analog Output (0...20 mA / 4...20 mA)
If the VSD requires an input signal of DC 0...10 V, a resistor of 500 Ω ±1 % must be
connected parallel to its input.
18.1.5 Configuration of fuel meter
The module can be used with fuel meters having a Namur or Reed output or open col-
lector (pnp).
To be able to adapt the module to different types of meters, the number of pulses corre-
sponding to a volume unit must be parameterized in the system.
The setting requires 4 or 5 decimal points. If one of these values shall be changed, the fol-
lowing setting procedure is required on the following menu:
«Params & Display» → «VSD Module» → «Configuration» → «Fuel Meter»
→ «Pulse Value Gas » or
«Params & Display» → «VSD Module» → «Configuration» → «Fuel Meter»
→ «Pulse Value Oil »

SELECT can be used to change the digit with the highest value of the numerical num-
ber, or ENTER can be pressed to switch to the next digit.
After selecting the last decimal place and pressing Enter , the value will be adopted.
After selecting the last decimal place and pressing Enter , the value will be adopted.
The setting procedure for «Pulse Value Oil» is the same as that for «Pulse Value Gas»,
the selectable units being 1 l or 1 gal.
