5.1 General maintenance instructions
WARNING
Contact with the sample can be dangerous for 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 the
sensor is taken out of the measuring position. This avoids unwanted
reactions of linked outputs. For more detailed information on the main-
tenance condition please refer to the respective IQ S
ENSOR N ET sys-
tem operating manual.
Note
We do not recommend unscrewing the sensor from the sensor connec-
tion cable in order to do maintenance work. Otherwise, moisture and/or
dirt can get into the plug connection where it can cause contact prob-
lems.
If you would like to disconnect the sensor from the sensor connection
cable, please note the following points:
 Before disconnecting the sensor from the SACIQ (SW) sensor con-
nection cable, the sensor has to be cleaned on the outside (see sec-
tion 5.4.1).
 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 mois-
ture or dirt can get on the contacting surfaces.
 In corrosive environments, close the socket of the sensor connec-
tion cable with the screwable SACIQ-Plug when it is dry in order to
protect the electrical contacts from corrosion. The protective plug is
available as an accessory (see section 5.5 R
EPLACEMENT PARTS AND
ACCESSORIES ). It is included in the standard scope of delivery of the
SACIQ SW sensor connection cable.
