If the unit has another Configuration, such that the
number of inputs, outputs, visual signals and/or
measurements is not the same as described
above, the procedure for designing the Test
Configuration is the same. Just keep that
difference in the number of signals in mind.
If the number of visual signals is less than eight,
only the first
L digital inputs are to be connected to
the LEDs, where L is the number of visual signals
of the Configuration.
If the number of Output Signals is greater than the
number of Digital Inputs, the connections diagram
should be modified so that a Single Input activates
more than one Digital Output, so that all the Digital
Outputs are verified as described in the figure on
the right.
Figure 10.4 Test Configuration (II).
10.6.2 Digital Inputs 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 the
Digital Inputs screen to verify that the
indicator corresponding to the activated input and
only that input is activated.
Repeat the process until you have activated each
and every Digital Input corresponding to the unit
being tested.

Inputs Test.
