Auto test overview

The device performs a series of auto-tests on start-up, and then at regular intervals during operation, to help detect any potential faults in its internal and external circuits.

The device’s auto test function tests:

  • The product: indicator lights, internal electronics.

  • The measuring chain, the insulation alarm relay and the preventive insulation alarm relay.

The auto-test is triggered:

  • Manually at any time by pressing the T contextual menu button on one of the system insulation monitoring screens.

  • Automatically:

    Whenever the device starts up (power-up or reset)

    Every 5 hours (except when the device has detected an insulation fault, regardless of whether the alarm is active, has been acknowledged, or is transient).
