Fixture opening
Every time that the fixture body is opened, all the seals must be replaced: use only original
spare parts by OCEM Airfield Technology.
Whenever the LERA fixture is opened, it must be ensured that:
●
the optical unit is undamaged and clean;
●
there are no infiltration;
●
the supply cables and the connectors are undamaged and do not have breakdowns or abrasions.
Unscrew the four captive screws and open the fixture. Disconnect the supply cables and the ground cable (1). If
present, disconnect the supply cables of the resistance of the arctic kit (2).
Remove the light assembly.
We recommend to immediately replace the light assembly with a functioning spare part. No
further adjustments are necessary when commissioning the new device.
Carry out any work necessary to restore normal operation of the light assembly in the maintenance centre.
