4.4 Protection unit interface

The SACE PR010/T test unit can perform all the operations described above without extracting
the protection units from the circuit breakers. The test unit (connector 1) is connected to the
releases by a cable fitted with a special connector. The SACE PR010/T test unit is connected to
the various types of release using the specific cables for each type of release.

4.5 PC interface

The SACE PR010/T test unit is fitted with a connector (3) for connection to a PC (standard
RS232 serial port). This interface is used to update the unit's software and download test reports.

4.6 Test report

The SACE PR010/T test unit can save the main test results in order to compile a test report. The
unit can store up to five test reports. After the test reports have been downloaded in the PC it is
advisable to delete them from the PR010/T so as to have enough free memory available for new
reports. The SACE PR010/T test unit saves data even when disconnected from the power supply.
Test results are downloaded to a PC when the user requests a test report. The test report contains
the following information, which is automatically supplied by the unit or manually entered by the
user:
- unit serial number (Sr. Nr.)
- date and time of test
- operator name
- type of unit tested
The following information is automatically indicated for each protection function tested:
• type of protection
