Set point adjustment
The set point can be specified by the customer or factory-set within the setting range. Subsequent adjustment of the setpoint on site is made using the adjustment screw, which isfastened to the switch and thus secured against loss.
Repeatability of the set point:≤ 1 % of span
Please specify:
Set point, switching direction for the contact, e.g.:
Set point: 5 mbar, falling
For optimal performance we suggest to adjust the set point between 25 ... 75 % of the span.
Example
Setting range: 0.4 ... 10 mbar with one switch contactRepeatability: 1 % of 9.6 mbar = 0.096 mbar
Dead band: (see table setting ranges)
2 x repeatability + dead band = 2 x 0.096 mbar + 0.3 mbar= 0.492 mbar.
Rising pressure: Adjust set point between 0.892 ... 10 mbar.
Falling pressure: Adjust set point between 0.4 ... 9.508 mbar.
