Safety Instructions
Pressure switches are precision devices
which are calibrated in the factory. For this
reason, never open the device and do not
change the adjustment of the varnished
calibration screws.
Prevent excessive vibrations from reaching
the pressure switch, e.g., with mechanical
isolation or other vibration damping
measures.
Heavily contaminated media can clog the
sensor and cause errors and/or malfunc-
tion. If the equipment is to be used for this
purpose, suitable chemical seals must be
connected.
Pressure switches and chemical seals form
a functional unit and must not be
disconnected from each other in the field.
Before disassembly (removing the
pressure switch from the system), the
device must be disconnected from the
power supply and the system must be
emptied. Observe the Accident Prevention
Regulations.
Never use the pressure switches as a
climbing aid.
