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).

    When injection is activated again after exiting the inhibited injection state.
