4.1 After Use
Take the following steps after the SLAM Star unit has been taken out from Ex-area
1) Clean the unit with a damp cloth (do not use detergents or solvents)
2) Change the anti-static film of the light unit tubes if only little light comes through it or it is
damaged
3) Have a visual check on the unit (condition of cable, light unit, enclosure, tightness of parts)
4) Let the unit dry in open air
5) Store the unit (see 3.2 Storage)
4.2 Repair
The following procedure should be taken in case the SLAM Star unit needs to be repaired
1) Repairs may be carried out only outside Ex –area
2) Person responsible for maintenance should have been trained the basics of explosion-
protection as well electricity
3) Only original spare parts from Atexor should be used. Please note that there are no
components in this unit which can be repaired by using glue, silicone or any other similar
method.
4) The dissipation feature (antistatic) on transparent parts of SLAM Star may be damaged
because of external affects like solvents or chemicals or mechanical stress. In case the
surface of the PC-tube is damaged in one area greater than 100 cm
2
the part has to be
changed. The surface resistance of the transparent parts has to be between 1 M
Ω…
1 G
Ω
.
Please contact Atexor in case you need a simple measuring device, which is needed for
measuring surface resistance of the PC-tubes.
5) Maintenance instructions with exploded-view diagram and spare parts list are available at
your local distributor and the manufacturer. Please, when requesting maintenance
instructions with exploded-view diagrams, include the model and serial number of the
product.
The device has electronics inside, please use required actions when disposing of
the device or its components.
4.3 Testing
Tests are to be done according to EN/IEC 60079-19 before returning the repaired unit back to
operation. The following tests shall be done in addition to the tests specified in EN/IEC 60079-19.
•
PE –resistance test
•
High-voltage test (500 VDC between Phase & Neutral against P/E conductor; N/A for 2-
pole units)
•
Operational test
•
Test of expected use (vibrations, shaking)
Proper testing ensures safe operation of repaired equipment.
4.4 Repair report
The operator is responsible for keeping up to date record of the condition of his equipment (EN/IEC
60079-14). Ensuring the availability of this important information each repair procedure should be
written down in repair report according to EN/IEC 60079-19.
