• It is not necessary for the auxiliary supply to be present in order to use the above releases with
the PR010/T unit.
• The automatic and manual tests must be performed with the circuit breaker off while the trip
test may be performed only with the circuit breaker on; in either case the circulating currents
must be null.
WARNING
For PR122/P releases with a software version prior to 1.0, the following
limitations must be considered:
A description of the various menus is given below.
14.3 Test
By means of the PR010/T unit it is possible to perform some tests on the protection unit, in
particular:
1. Automatic test
2. Manual test
3. Trip test
4. Sign. mod. autotest
5. Force output S ZS
6. Force output G ZS
7. Release output ZS
8. Rc Test
For example, to perform the automatic test it is necessary to follow the procedure described in the
following table:
1. Startup time protection S:
0.1 s ≤ Time ≤ 1.5 s step 0.01 s
2. Startup time protection S2:
0.1 s ≤ Time ≤ 1.5 s step 0.01 s
3. Startup time protection G:
0.1 s ≤ Time ≤ 1.5 s step 0.01 s
4. Startup time protection Gext:
0.1 s ≤ Time ≤ 1.5 s step 0.01 s
5. Startup time protection D:
0.1 s ≤ Time ≤ 1.5 s step 0.01 s
6. Startup current activation threshold not contemplated
7. Protection U threshold: 5% ≤ th ≤ 90% step 5%
8. Management of unit contacts on local bus not contemplated.
