ERA 500 Hybrid IP Safety and Installation Manual
• If the level is below 45%, the fixture will run the dehumidification program for 30 seconds.
The fixture will then stop the dehumidification program and the control panel display will return to the
main menu page.
Note that you can stop the dehumidification process at any time by selecting EXIT in the control panel
and pressing ENTER to confirm.Note also that, for safety reasons, you cannot run the dehumidification
process if the fixture is too hot (above 65° C or 149° F).
6. If the fixture is receiving a DMX signal, it will begin to obey DMX control. If no DMX signal is present, the
fixture will go to standby.
7. Shut down power the fixture. Check that the pressure relief valves and their O-rings are clean, dry and in
perfect condition. If in any doubt, replace the valves with new items. Reinstall the valves, tightening them
to 0.6 - 0.8 Nm.
8. When the fixture is powered on again it will no longer be in Service mode: pan and tilt will no longer be
immobilized.
Vacuum testing
To be sure that the fixture’s IP65 rating is maintained, it is necessary to vacuum test the fixture after
reassembly each time you have removed a cover (including the rear cover during lamp replacement or lamp
readjustment). You will need the following items:
• Vacuum tester – you can obtain a suitable tester from Martin (see “Related Items” on page 26).
• M12 x 1.5 adapter, available from Martin (see “Related Items” on page 26), to connect the tester to the
fixture.
• Vacuum pump with a minimum capacity of 30 liters per minute that can create a vacuum of minimum
10 kPa (0.1 bar), maximum 50 kPa (0.5 bar). Suitable pumps are available commercially – the instructions
supplied with the vacuum tester include some suggested products.
• Two M12 x 1.5 nylon or steel blanking plugs with rubber seals. Suitable blanking plugs are available
commercially.
When you test the fixture, follow the instructions supplied with the vacuum tester. Disconnect any cables
that are connected to the fixture. See Figure 9. Install all the connectors’ rubber seals

on the connections side of the base and screw the M12 x 1.5
vacuum tester adapter with its O-ring seal into this valve’s threaded hole.
After testing is complete, remove the tester adapter and blanking plugs. Check that the rubber seals on the
pressure relief valves are in perfect condition and that the valves are perfectly clean. If in any doubt, replace
the valves with new items. Reinstall the valves, tightening them to 0.6 - 0.8 Nm.
