temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use!!
Improper handling can result in considerable personal injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
staff who have the appropriate qualifications. For installation and starting of the sensor the
relevant regulations and directives of the country and the norms must be observed.
Especially during installation of the sensor it is possible depending of the use to come
into contact with aggressive media. The safety instructions must be observed. There is
danger to life if live parts are touched. Electrical installation and commissioning may only
be carried out by qualified and skilled personnel.
Residual media in dismantled devices can result in a risk to personnel the environment
and equipment. Sufficient precautionary measures must be taken here. Do not use the
instruments in safety or emergency stop devices. Incorrect application or operation of the
instrument can lead to injuries. Depending on the application aggressive media with
extreme temperatures and high pressure or vacuum may be present at the instrument in
the event of a fault. We recommend installing and removing the device only at ambient
temperature and in a pressureless mode.

Our devices have a very high protection class when properly mounted and installed.
When cleaning your system with high-pressure cleaners steam cleaners etc. make sure
that both the cover and the cable screw connection are not directly exposed to the pressure
jet. If the temperature falls below the dew point condensation may form in the connection
chamber of the device. For such extreme applications contact our sales and technical
support before commissioning.

The analog output can be operated actively or passively. Attention: The changeover
must only be carried out in a de-energized state. Destruction of the electronics may result.
analog output aktiv: This is the delivery status of the WTR 191... The DIP switches
D1...D3 are switched up. The current signal is 4....20mA active
and must not be supplied by a sensor supply. You go with it to
the passive input of your SPS or similar.
analog output passiv: By switching the DIP switches D1...D3 downwards the current
output is switched passively. The current signal is 4....20mA
passive and must be powered by a sensor supply. You use it to
go to the active input of your SPS transmitter power supply or
similar.

mechanical installation
return and repair
electrical mounting
- The WTR 191 is designed as a wall-mounted sensor. Use the holes provided in the
housing for mounting. Use suitable screws that do not destroy the housing. Only by this
we can guarantee you an optimal measuring point incl. the protection class.
- After mounting the sensor check the tightness of the housing and after installing the
connection cable check the tightness of the screw connection (cable entry).
- The electrical installation must be carried out in a de-energized status.
- Insert the connection cable into the cable entry (screw fitting). Be careful not to damage
the seal of the cable screw fitting.
- Connect the connecting leads according to your switching task.
- You can parameterize the device via the USB interface.
- Close the housing and switch on the voltage.
The promesstec sensors have a modular design. This allows us to repair and
overhaul defective devices. To do this send the device to promesstec. You will find a
return form with the information to be provided on our homepage under
"technical information".
