Accessories
13.18.1 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” and “Iinst” to be checked either manually or automatically.
Furthermore it is possible to obtain a test report and modify the settings.
For operation of the PR010/T accessory, please consult the special instruction manual.
13.18.2 ABB SACE PR020/K signaling unit
The PR020/K signaling unit, when connected to the internal bus of the PR112/P-A, allows the state of the protection functions and of the
PR112/P-A trip itself to be signaled by means of clean power contacts.
The PR020/K must be supplied with 24Vdc ±20%.
For operation/installation of the PR020/K accessory, please consult the special instruction manual.
The unit must be connected to the PR112 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.
13.18.3 ABB SACE PR120/B power supply unit
The PR120/B is a supplementary power supply unit with front connection (by means of the test connector).
It is possible to read and configure the parameters of the PR112 unit whatever the status of the power circuit breaker (open, closed, in the test
position or racked-in, and with/without auxiliary power supply) with this accessory, which is always supplied,
Inside it there is an electronic circuit which allows power supply to the unit for about 3h continuously, just to carry out the sole operations of reading,
configurations and testing.
Its autonomy decreases, proportionally to its use, if the PR120/B accessory is also used to carry out the functions of the “Test” menu (Trip test,
Self-test).
