PAT Testing Avolites ART2000 Dimmers 

Make sure that the dimmer is disconnected from the mains supply, and is not connected to any other equipment

Only PAT test if qualified to do so, PAT testing can be hazardous if performed without due care.

Read the PAT tester instruction manual for further information on PAT testing.

The Avolites ART 2000 system is a CLASS I appliances.
 
Earth continuity test.
The earth continuity test can be performed with 100mA across the whole of the dimmer
Take care when testing with 25A as control panel connection is only rated at 16A 
 
Insulation resistance test.
The Neon Indication Board on the control front sinks 0.4 mA into the earth to indicate the proper phase connections.
This current will cause the insulation test to fail, therefore the earth connection to the NIB needs to be disconnected before an insulation test is performed.
The NIB remains energized during the test as only the earth connection is disconnected

The ART2000 can be PAT tested without damage if the following procedure is followed.
  1. Disconnect any outgoing cables including the DMX cables
  2. Open the dimmer output Patch panel, ( the patch panel with the battery holder)
  3. Disconnect the earth lead to the NIB board (marked “disconnect for PAT testing “ near the PSU)
  4. Prop the manual relay actuator to the “I” position (i.e. using a cable tie)
    !! DO NOT USE A SCREWDRIVER FOR THIS !!!
  5. Switch the Phase selector to “R”
  6. Test the System for insulation resistance
    The reading should be greater that 19 M Ohm when testing at 20 degrees Celsius 30% ,relative humidity
  7. Reconnect the NIB. board earth lead and test again the insulation resistance should come down to 1.5M Ohm 
    !!Be aware that neon’s will light up during this test! 
 
Run earth leakage current.
Disconnect any outgoing cables including the DMX cables
Switch the control mains selector to “R” and start the test.
The nominal earth leakage during runtime is 0.5mA
 
Flash Test
Flash Testing can result in permanent damage to the dimmer.
Generally flash testing is not needed for this type of equipment.
If however a flash test is needed please contact Avolites for further instructions.
Avolites Flash tests the dimmer bays during production to insure proper insulation.
