The following applies for all models:
Changes of the setpoint spindle to the set
the switching pressure do not lead to
changes in the switching intervals; how-
ever, the switching points will translate in
parallel correspondingly.
The switching differential of the individual
microswitches corresponds to the
switching differences listed under basic
equipment.
The switching differential cannot be set for
individual microswitches in two-stage
pressure switches.
The switching points can be moved parallel
to the setting spindle.
