TRIGGER (Response threshold for the MIN parameter)

Command
MIN
MAX
TRIGGER
With this command, the output signal is adjusted to the valve characteristics. With the MAX value the output
signal (the maximum valve current) will be defined. With the MIN value the overlap (dead band of the valve)
will be compensated. Via the TRIGGER the activation point of the MIN function is set and so a non-sensitive
range around the zero-point
CAUTION: If the MIN value is set too high, it influences the minimal pressure, which cannot be ad-
justed any longer. In extreme case this causes to an oscillating at small input values.
5
This dead band is necessary, in order to avoid unrequested activations caused by small variations of the input signal. If
this module is used in a position controls, the TRIGGER value should be reduced (typical: 1...10).
