Abb Sace Pr010/T Test And Configuration Unit - ABB SACE Emax Series Installation, Service And Maintenance Instructions

1 3 . 7 . 1 In the case of a fault
If you suspect that the PR122/P is faulty, has a malfunction or has generated an unwanted trip, it is advisable to follow the
recommendations below very carefully from the Measurements menu
1. Make a note of the type of protection that has tripped by accessing the LAST TRIP page if there is an external power supply (Vaux or battery)
or by pressing "i Test" if in self-supply mode.
2. Note down the type of circuit-breaker, number of poles, any accessories connected, In, Serial Number (see par. 13.4) and the SW version.
3. Prepare a brief description of the opening (what LEDs and/or indications were displayed? when did it happen?, how many times ?, was it always
under the same conditions? what type of load? what voltage? what current? is the event reproducible?)
4. Send/communicate all the information collected, together with the circuit diagram for the circuit-breaker, to your nearest ABB Customer Support
service.
The completeness and accuracy of the information given to the ABB Assistance service will facilitate technical analysis of the problem encountered,
and will allow us to carry out all actions useful for the user rapidly.
13.8 Accessories

1 3 . 8 . 1 ABB SACE PR010/T test and configuration unit

Testing by the SACE PR010/T unit allows checking correct operation of thresholds and trip times of "L", "S", "I", "G", OV, UV, RV, U protection
functions. The test unit is connected to the relay through a dedicated connector (see par. 13.4).
1 3 . 8 . 2 BT030 communication unit
Through a BT030 wireless communication unit, the PR122/P can be connected via wireless to a Pocket PC (PDA) or a standard PC, extending
the range of information available to user. By means of the ABB SACE SD-Pocket communication software, the values of the currents flowing through
the circuit-breakers, the value of the latest 20 interrupted currents and protection settings, can be read.
1 3 . 8 . 3 PR021/K and HMI030 units
The PR122/P can also be connected to the optional external PR021/K unit (see par. 16) to indicate through potential-free power contacts alarms
and protection trips, and to the HMI030 switchboard front unit to display a number of information.
1 3 . 8 . 4 PR030/B power supply unit
The PR030/B power supply unit is an external unit allowing powering of Relay, Autotest and Trip Test, checking with CB open and installation of
new replacement units.
