2.2.3 Automatic test
The automatic test must be performed with the circuit-breaker open.
The data acquisition channels are tested for each phase (L1, L2, L3, Ne) and the main protections
of the unit are tested (e.g. trips with protections: L, S, I and G with PR212/P LSIG; L, R, I, U with
PR222MP) for each relay, regardless of its functional characteristics and version..
During the various different tests, the tripping times of the relay will depend on the protection
settings. The PR010/T unit displays the threshold and time of the protection in question, as well as
the test result (OK or FAILED).
At the end of the test, the user is aked whether a test report must be recorded. This can then be
downloaded into a PC.
2.2.4 Set/Reset Coil test
Operation of the SET and RESET outputs that control the PR212/CI unit can be tested for the MP
relay versions (PR212MP and PR222MP). Each test command transmits a status change signal to
the PR212/CI unit.
CAUTION
Before transmitting a Set/Reset test command, make sure that the PR212/CI
unit is in the opposite position, so as to check the switching function.
2.2.5 Iinst test
Operation of the Iinst protections can be tested in PR11x series relays. The PR010/T unit will
display the test result (OK or FAILED).
CAUTION
Before accessing the menu, make sure that the circuit-breaker model and
the setting of the dip switch on the upper side of the relay correspond. If
they are misaligned, an error message will be displayed by relays PR112 and
PR113, and access to the menu will be inhibited.
