The SACE PR010/T unit is an instrument capable of performing the functions of testing, programming and reading parameters for the protection units equipping SACE Emax low-voltage air
circuit-breakers.
In particular, the test function involves the following units:
– PR121 (all versions)
– PR122 (all versions)
– PR123 (all versions)
whereas the parameter programming and reading functions regard the range of PR122 and
PR123 trip units.
All of the functions mentioned can be carried out “on board” by connecting the SACE PR010/T
unit to the front multi-pin connector on the various protection units. Special interfacing cables
supplied with the unit must be used for this connection.
The human-machine interface takes the form of a touchpad and multi-line alphanumeric display.
The unit also has two LEDs to indicate, respectively:
– POWER-ON and STAND BY
– battery charge state.
Two different types of test are available: automatic (for PR121, PR122 and PR123) and manual.
By connection to a PC (using the USB 512 MB supplied by ABB SACE), it is also possible to
upgrade the software of the SACE PR010/T unit and adapt the test unit to the development of
new products.
It is also possible to store the most important test results in the unit itself, and to send a report to
the personal computer with the following information:
– type of protection tested
– threshold selected
– curve selected
– phase tested
– test current
– estimated trip time
– measured trip time
– test results.
At least 5 complete tests can be stored in the memory. The report downloaded onto a PC allows
creation of an archive of tests carried out on the installation.
In automatic mode, the SACE PR010/T unit is capable of testing the following with the PR122
range:
– protection functions L, S, I,
– G protection function with internal transformer,
– G protection function with toroid on the transformer star centre,
– monitoring of correct microprocessor operation.
The unit can also test the following protections of PR122 equipped with PR120/V:
– overvoltage protection function OV,
– undervoltage protection function UV,
– residual voltage protection function RV,
– phase unbalance protection function U.
The SACE PR010/T unit is portable and runs on rechargeable batteries and/or with an external
power supply (always supplied) with a rated voltage of 100-240V AC/12V DC.
The standard version of the SACE PR010/T unit includes:
– SACE PR010/T test unit complete with rechargeable batteries
– SACE TT1 test unit
– 100 – 240V AC/12V DC external power supply with cord
– cables to connect the unit and connector
– cable to connect the unit and computer (RS232 serial)
– user manual and USB 512 MB containing application software
– plastic bag
