Digital Outputs and LEDs Test
Connect a Breaker to each of the unit's Digital
Inputs that correspond to the Control system. Bear
in mind that some of the available Digital Inputs
are distributed by pairs.
Activate each of the Inputs one after another and
check that, when you do this, the Output
corresponding to the same numerical index (or the
corresponding one according to the connections
diagram that has been drawn up) is activated.

Outputs and LEDs Test.
10.6.4
Metering Test
This test checks whether or not the following items are correct: the Measurements that the
Protection or the Measuring board picks up and sends to Control, the Measurements picked up
through the Input Transducers and the Measurements sent to the Output Transducers.
Therefore, this section will only be applicable in those cases in which there is Measurement of
Current, Voltage or Input Transducers.
Measurement of Current sent by Protection or the Measuring Board
Connect a source of alternating current to the terminals corresponding to Measurement of
Current for your model and check the measurements indicated in following table from
Communications or on the Measurements Screen in the Graphic Display.

Check that the current described in the table appears through the Transducer Output.
Voltage Measurement
Connect a source of alternating voltage to the terminals corresponding to the unit's
Measurement of Voltage and check the measurements indicated in following table from
Communications or on the Measurements Screen in the Graphic Display.
