The trip times of the release in the various tests will depend on the settings of the protections; on
the display the PR010/T unit will show the trip time and the result of the test (OK/FAILED).
At the end of the test it is asked whether to record a test report which may later be downloaded on
a PC.
14.3.2 Manual Test
The manual test allows the release trip time to be tested with the desired load condition, in
particular it offers the possibility of selecting the current value in a range between 0.00 and 16.00
In, the voltage value in a range between 0.0 and 1.3 Un, the phase shift between -180° and +180°
with step 0.75°, and of selecting the phases involved in the test (L1, L2, L3, Ne, Gext, V1, V2,
V3).
The release trip time will depend on the settings of the protections; on the display the PR010/T
unit will show the trip time and the result of the test (OK, FAILED).
At the end of the test it is asked whether to record a test report which may later be downloaded on
a PC.
14.3.3 Trip test
With this test it is possible to send a command to turn off the circuit breaker, thus checking the
functionality of the protection opening system.
The trip test command is accepted by the protection unit only if the circuit breaker is on.
14.3.4 Sign. mod. autotest
When this item is selected, the autotest of the signalling module is launched. Refer to the
signalling module manual for further information on this function.
14.3.5 Force output S ZS
Activates the zone selectivity output of the protection S; this command allows checking of the
zone selectivity function on the system.
14.3.6 Force output G ZS
Activates the zone selectivity output of the protection G; this command allows checking of the
zone selectivity function on the system.
14.3.7 Release output ZS
Deactivates both the zone selectivity outputs of the protections S and G; this command allows
checking of the zone selectivity function on the system.
