5 REPAIR AND SERVICE
The sensor should be cleaned and the operation should also be tested
when emptying the oil storage chamber or at least once every six
months. The easiest way to check the operation is to lift the sensor up
in the air and to put it back to the separator. The operation is described
in chapter 3.
For cleaning, a mild detergent (e.g. washing-up liquid) and a scrubbing
brush can be used.
The mains fuse (marked 315 mAT) can be changed to another glass
tube fuse 5 x 20 mm / 315 mAT complying IEC/EN 60127-2/3. Any other
repair and service works on the device may be carried out only by a
person who has received training in Ex-i devices and is authorized by
the manufacturer.
In case of queries, please contact Labkotec
Oy’s service.
6 SAFETY INSTRUCTIONS
SandSET-1000 12 VDC control unit must not be installed in potentially
explosive atmosphere. Sensors connected to it may be installed in zone
0, 1 or 2 potentially explosive atmospheres.
In case of installations in explosive atmospheres the national
requirements and relevant standards as IEC/EN 560079-25 and/or
IEC/EN 60079-14 must be taken into account.
If electrostatic discharges can cause hazards in the operating
environment, the device must be connected into equipotential ground
according to requirements with regards to explosive atmospheres.
Equipotential grounding is made by connecting all conductive parts into
same potential e.g. at the cable junction box. Equipotential ground must
be earthed.
When executing service, inspection and repair in explosive atmosphere,
the rules in standards IEC/EN 60079-17 and IEC/EN 60079-19 about
instructions of Ex-devices must be obeyed.
