Trip/Close Coil Circuit Supervision Input Test
To check that the switching circuits are properly monitored, you can observe the state of the
inputs used on the screen,
Information
-
Status Contact Inputs
.
Both monitoring inputs of a circuit, whether for opening or for closing, must not be set to “1” or
“0” at the same time. If they were, they would be in fault; that is, the two inputs must be in
different states at any given time.

Control Subsystem Receiving Tests
The Control Subsystem of each unit has a specific Configuration loaded. The Control
Subsystem receiving tests do not attempt to check the Control Logic but rather the hardware
associated with it, that is, the measurements sent by Protection, the measures taken through
transducers or instrument transformers, the physical inputs, the physical outputs and the visual
signals. This requires using the communications program with the Control Subsystem
ZIVerlog
®
to load a specific Test Configuration for each unit. This Test Configuration, if desired, can be
provided by
ZIV
.
10.6.1
Test Configuration
Implementation of the Test Configuration
The Test Configuration described next represents a concrete example for a unit with the
following physical characteristics:
Current measurement processed by the CPU Protection and sent to Control
24 Digital Inputs
17 Digital Outputs
1 “In Service” Output
The Control Subsystem is configured thus:
Measurements: the one corresponding to
current channel (A) must be made to appear on
the measurements screen.
Logic / Inputs / Outputs: the inputs, outputs and
visual signals are connected according to the
diagram to the right.
The designations of Digital Inputs and Physical
Outputs according to the diagram of external
connections (user). With this configuration
loaded, run the following tests:
- Test of Digital Inputs
- Test of Digital Outputs and visual signals
- Measurement Test
