Flash Tests – LN-Outer Surfaces and L-N

29. This test will require use of the safety Flash Probe – if it isn’t already connected into the rear panel socket,

plug it in before proceeding


30. Check that the TEST INHIBIT lamp is off – if it’s on, check that no Lamp Simulators have been left plugged

into any of the lampholders. Check that the test item is secure and stable and cannot move about.

DO NOT TOUCH, HOLD OR COME INTO BODILY CONTACT WITH THE ITEM WHEN FLASH TESTING


31.
Hold the remote Safety switch in one hand and depress (and hold in) the button on the end. With the same

hand, depress the panel mounted LN-E test button. With the other hand pick up the red Flash probe and
expose the test tip by depressing the red button on the handle.


32. Apply the probe tip to any metal trims on the product and over all outer surfaces of the product, paying

particular attention around body joint-lines, switches, lampholders, cable entries etc. to check that there are no
protruding wire ends etc. The red FLASH FAIL lamp and internal audible alarm should remain off. Release
both the remote Safety button and the LN-E button. Stow the probe safely away.


33. Now apply the L-N test (this test doesn’t require the probe) - operate the remote Safety switch with one hand

and then depress the L-N panel button with other hand - again the FAIL lamp and alarm should remain off.


34. If the FAIL lamp and alarm come on, a flashover has occurred or the leakage current exceeds the

permissible level. Release the Safety and test buttons, then momentarily depress the Flash Fault /
Reset button to reset the fault indications.
