5.2.2 Wiring test for inputs
Check the wiring by carefully changing the wiring of field devices (e.g. sensors or
switches) connected to the inputs, or by simulating sensor values or contact states.
Reference data points are refreshed.
1. Select
Applications > Popcard…
and check for "Wiring test active = Yes".
2. Select
Inputs
to open data points N.X1…N.X8 and N.D1…N.D8.
3. Change (or simulate) sensor values or contact states.
4. Check how the values have changed.
Universal inputs N.X1…N.X8 with "Input identifier = Pulse" cannot be checked during
the wiring test. However, they are displayed in
[Popcard]
under
Meter > Meter 8
(see below
with Meter 8 as an example).
Requirements:
•
Reference data point "Wiring test active
= No"
•
Reference data point "Commissioning mode = Off"
