SMARTPAT ORP
Digital sensors for ORP measurement
Connecting the cable to the sensor
For connection use only a VarioPin cable with shield wire, like the cable VP2-S.
Ensure that both cable and sensor connector are absolutely dry
Screw the cable connector on the sensor connector and tighten it by hand

Installation, assembly, start-
up and maintenance may only be performed by appropriately trained personnel.
Check the nameplate for correct operating conditions.
For use in hazardous areas, special codes and regulations are applicable. Instruments must not be
connected to power supply before reading instructions described in the supplementary manual.
The responsibility as to the suitability, intended use and corrosion resistance of the used materials of this
device
against the measured fluid
rests solely with the operator.
SMARTPAT ORP
sensors are factory calibrated. Nevertheless it is recommended to calibrate the sensor
before installing it into its final measuring location.
1.
Connect the sensor to a device suitable for SMARTPAT
ORP sensor calibration: OPTIBRIDGE / PC,
SMARTMAC, HART handheld, or your PLC.
2. Calibrate the sensor.
3. Install the sensor into its final measuring location.
1 Unpacking the sensor
Remove the protective cap from the sensor tip by gently twisting and pulling it
.
• Lay the sensor on a soft ESD mat or soft paper tissue
.
• Leave the protection cap
on the VP connector, as long as the sensor is not connected to the cable.
2 Electrical connection
Danger:
All work on the electrical connections may only be carried out with the power disconnected.
Take note of the voltage data on the nameplate.
Observe the national regulations for electrical installations.
