15.2 Indications on operation
• The SACE PR010/T unit can be used with all SACE PR123/P releases by connecting the test
unit to the protection unit with the cable provided, to be inserted in the test connector on the
front.
• 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 PR123/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.
15.3 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
