Maintenance and cleaning ...
For sensor maintenance observe the following safety information:
– The maintenance must be carried out only by expert personnel and in compli-
ance with all applicable safety regulations. This also applies to any local safety
and accident prevention regulations which are not stated in this user guide.
– The sensors are suitable for installation in Ex Zone 0.
Observe all applicable rules and regulations for potentially explosive atmos-
pheres (VDE in Germany respectively national installation rules and regulations).
– For servicing, the sensors must be disconnected from power supply.
– To avoid the risk of electrostatic charge, always use a damp cloth to clean the
SEPARIX-C L Plus interface sensors.
As the sensor has no moving parts, no special maintenance is required.
The sensor needs only to be cleaned routinely as part of regular maintenance, cleaning
and clearance work on the separator.
3.3.1
... of the interface sensor SEPARIX-C L Plus
Clean the sensor with a damp cloth to minimise the effects of contaminants that could
trigger a false alarm (see section 3.1). Grease-dissolving cleaning agents can be used for
heavy contamination.
It is recommended to test the sensor whenever it has been cleaned (see section 5).
3.3.2
... of the high-level sensor SEPARIX-T L Plus
Check the sensor routinely for contamination as part of maintenance work on the separa-
tor and after an alarm, and, if necessary, clean it to prevent faulty operation.
After an alarm, the sensor tip in particular should be inspected for contamination. If the
sensor tip is encrusted with dirt, this can be cleaned away using a soft brush and a grease-
dissolving cleaning agent.
Do not use sharp-edged objects to clean the sensor tip under any circum-
stances.
It is recommended to test the sensor whenever it has been cleaned (see section 5).
