15.7 Accessories
15.7.1 ABB SACE PR010/T complex test unit
The test with the SACE PR010/T unit allows correct operation of the inputs, outputs, thresholds and trip times of protection functions “L”, “S”, “I”,
“G”, “U”, “Iinst”, “UV”, OV” and “RV” to be checked either manually or automatically.
Furthermore it is possible to obtain a test report and modify the settings of the PR113 unit.
For operation of the PR010/T accessory, please consult the special instruction manual.
15.7.2 ABB SACE PR020/K signaling unit
The PR020/K signaling unit, when connected to the internal bus of the PR113/P, allows the state of the protection functions and of the PR113/P
trip itself to be signaled by means of clean power contacts (250V AC, 5A).
The user has the possibility of individually “combining” one of the signals defined to par. 15.2.10.with each of the 7 K51 power relays, inside the
PR020/K.
In this way, the user can obtain indication of the signals considered most important by means of clean power contacts.
If the signaling requirements are the classic ones (Alarm L, S, I ... Trip), these are preconfigured in the PR020/K, making putting into service immediate.
The PR020/K must be supplied with 24V DC ±20% Vaux.
For installation and operation of the PR020/K accessory, please consult the special instruction manual .
The unit must be connected to the PR113 by means of an internal bus with a corded shielded cable with two conductors
(see note A of par. 11.2.2) with a maximum length of 15m .
The shield must be grounded both on the power circuit breaker side and on the PR020/K side.
15.7.3 ABB SACE PR120/B power supply unit
The PR120/B is a momentary power supply unit to be inserted in the front TEST connector of the PR113.
With this accessory, supplied as standard, it is possible carry out the test, read and configure the parameters of the PR113 unit whatever the status
of the power circuit breaker (open, closed, in the test position or racked-in, and with/without auxiliary power supply).
Testing the PR113 with the power supply supplied by the PR120/B, it is normal for the display to turn off for a few seconds after a trip test.
The battery inside the PR120/B guarantees power supply to the unit for about 3h continuously (depending on the operations carried out on the
PR113)
