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 125 mAT) can be changed to another glass
tube fuse 5 x 20 mm / 125 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.

SAFETY INSTRUCTIONS
OilSET-1000 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 60079-25 and/or
IEC/EN 60079-14 must be taken into account.
Warning! If the cabling is voltage-tested, the sensor must be
disconnected.
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.
The device does not include a mains switch. A two pole mains switch
(250 VAC 1 A), which isolates both lines (L1, N) must be installed in the
main power supply lines in the vicinity of the unit. This switch facilitates
maintenance and service operations and it has to be marked to identify
the unit.
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.
