replacement
5.1 General maintenance instructions
Warning
Contact with the sample can lead to danger to the user!
Depending on the type of sample, suitable protective measures
must be taken (protective clothing, protective goggles, etc.).
Maintenance condition We recommend to switch on the maintenance condition each time
before removing the sensor from its measuring position. This avoids
unintended reactions of linked outputs. For more detailed information
on the maintenance condition please refer to the respective
IQ S
ENSOR N ET system operating manual.
When to unscrew the
sensor from the
connection cable?
To clean the outside of the sensor (section 5.2) and to replace the
electrolyte solution and membrane head (section 5.3), we recommend
to leave the sensor connected to the sensor connection cable.
Otherwise, moisture and/or dirt can get into the plug connection where
they can cause contact problems. If you wish to disconnect the sensor
from the sensor connection cable, note the points described below.
For the cleaning of the electrodes (section 5.4) the sensor must be
unscrewed from the sensor connection cable to prevent any damage.
Observe the following points for this:
 Before disconnecting the sensor from the SACIQ (SW) sensor
connection cable, remove any larger pieces of contamination from
the sensor, particularly in the area of the plug connection (brush it
off in a bucket of tapwater, wash it off with a hose or wipe it off with
a cloth).
 Unscrew the sensor from the SACIQ (SW) sensor connection cable.
 Place a protective cap on the sensor plug head connector and on
the SACIQ (SW) sensor connection cable each time so that no
moisture or dirt can get on the contacting surfaces.
 In corrosive environments close the dry socket of the sensor
connection cable with the SACIQ-Plug protective screw cap in order
to protect the electrical contacts from corrosion. The protective cap
is available as an accessory (see section 5.8 M
AINTENANCE
EQUIPMENT AND REPLACEMENT PARTS ). It is included in the standard
scope of delivery of the SACIQ SW sensor connection cable.
 Connect the sensor with the SACIQ (SW) sensor connection cable
again before polarization.
