Indications on operation
• The SACE PR010/T unit can be used with all SACE PR222DS/P and SACE PR222DS/PD
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.
• During use of the PR010/T unit, communication between the SACE PR222DS/PD releases
and the supervision system connected to them is interrupted.
• Tests must be carried out with the circuit breaker off.
• Automatic testing and manual setting with default parameters must be performed only by con-
figuring the release in Electronic SET (ELT) with the dip switch provided.
• The manual test may be performed either with Electronic SET or with manual SET. In the case
of manual test with manual SET, thresholds and curves must be selected with the dip-switches
on the protection; they are automatically updated on the display of the PR010/T unit, where
only the test current and the phase on which it is to be applied must be set.
• If during test, reading or programming operations, CB type and CT current rating are not yet
defined, the following message will be displayed:
