Settling time
Note
Pulse value gas
Pulse value oil
If oscillations occur during extensive running times, the settling time between accelera-
tion ramp and speed measurement can be extended to overcome the problem.

17.1.4 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.
If the VSD requires an input signal of DC 0...10 V, a resistor of 500
connected parallel to its input.
17.1.5 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»
«Pulse Value Gas » or
«Params & Display»
«VSD Module»
«Pulse Value Oil »
