2.2.6 Notes about the Relays
Consider the following indications to ensure that the tests are performed correctly.
2.2.6.1 PR111 and PR111/VF
• Before any test can be performed, certain data concerning the model and size of the CB must
be entered (e.g.: E1B, 800A). The Neutral setting (50% / 100%) and the version of the unit
(LI, LSI, LSIG) must also be etered in certain cases.
• Enter the settings of the protections in the following way before performing the Automatic
test:
NOTE: the PR111/VF relay does not control protections S, G and Iinst. This means that the
setting of the G protection must not be considered for automatic test configuration.
• The maximum trip time tolerance is 35% for the G function.
• The minimum threshold in the Manual Test configuration is 0.6In for the G function.
2.2.6.2 PR112
• PR010/T unit compatible with all PR112 relays in the IEC version with key, 2.20 SW version
or more recent and serial number after xxxxxx03x (for PR112/P units) or xxxxx05x (for the
PR112/PD versions).
• Notes for the G protection function test:
• For the automatic test, the I4 threshold setting must be 0.4In or more (if a lower value
was entered, the PR010/T unit would automatically override to 0.4In during the test).
The value of the test current is 2.5xI4.
• The value of the test current in the manual test is 1.5In.
• After a test with tripping on the G protection function, the protection may trip several
times more during the next 2s.
• PR112 contact wear: during the PR112 test, the operation count and contact wear signal could
increase after the opening command has been generated with over 10s timing. After a few
tests, the wear could reach 100% of the value and lead to an EMERGENCY warning. This
warning can be reset by the customer in the following way:
• Access the READ mode and select the page containing the contact wear indication
• Turn the key to EDIT
• Press the “Up” and “Down” keys for at least 5s. This will reset the contact wear and
operation count indication.
