WARNING

This symbol indicates information about procedures or situations that may

cause injury to personnel, damage to the unit or financial loss.

WARNING

Carefully read the entire contents of this handbook. Damage resulting from

failure to comply with the instructions effectively invalidates the terms of

guarantee. The manufacturer declines all liability for damage to the unit

caused by incorrect or improper usage.

ABB SACE also declines all liability for any ensuing damage or injury. Do

not use the unit in damp or wet environments.

If in doubt about the safety of the unit, take it out of service to prevent

inadvertent usage.

The unit's safety may be impaired if:

1. the unit shows visible signs of damage

2. the unit does not work

3. the unit is stored for a long period or has incurred damage during shipment.

Do not switch on the unit immediately after having transferred it from a hot environment to a cold

3. General information

3.1 Introduction

The SACE PR010/T unit is an instrument capable of performing the functions of testing,

programming and reading parameters for the protection units equipping ABB SACE low-voltage

circuit-breakers. For the specific functions, refer to the respective protection unit. All of the

functions mentioned may be carried out "on board" by connecting the SACE PR010/T unit to the

front connector on the protection unit. Two different types of test are available: automatic and

manual. It is also possible to perform the trip test through the SACE TT1 unit.

By connecting to a PC (using the disc supplied by ABB SACE, or SW downloaded from the ABB

Internet site) it is possible to upgrade the software of the SACE PR010/T unit. The unit can also

save important test results, which may then be downloaded to a PC following a request for a test

report.

The SACE PR010/T test unit is a portable instrument operated by rechargeable batteries and/or an

external power supply.

3.2 Putting into service

To put the SACE PR010/T unit into service, proceed as follows:

• Fit the batteries in the corresponding battery compartment (13), taking care to check the

polarity first.

• Connect the external power supply to the 12 Vdc outlet (11).

• Wait for the batteries to charge (when the PR010/T unit is switched off, the battery charge

status bar is stationary). Even when the batteries are discharged, the PR010/T unit can still

operate if connected to the external power supply.

4. Functions

4.1 Test Functions

The SACE PR010/T test unit tests protection units by monitoring both their HW and SW

components. In particular, the unit performs the following tests:

• Trip test: by means of SACE TT1 unit

• Protection functions test

• Communication functions test

4.1.1 Trip test

The trip test tests the operation of the microprocessor, release and opening solenoid chain.

The trip test may also be performed with the circuit breaker on.

This test is performed by means of SACE TT1 unit.

WARNING

For safety reasons, the current flow inside the circuit breaker must be zero

during testing.

For this reason, the current flow is automatically monitored before testing and registered as zero if

the reading detected is below a preset value.

4.1.2 Protection functions test

The device under test is powered up and the fault condition for the protection function to be tested

is simulated. In case of units provided with internal bus, the internal status of the protections

(alarm and trip messages etc.) may also be monitored.

In case of certain releases, the type of release and circuit breaker and the rated current of the CTs

installed are also automatically identified.

WARNING

For safety reasons, protection function tests must only be performed with

the circuit breaker off.

These tests may be performed in both automatic and manual mode.

•Automatic mode: releases equipped with internal bus (see electrical diagrams in the

Technical Catalogue) are automatically tested. The PR010/T unit is in fact capable of self-

learning the protection parameter settings and, based on these parameters, of generating a fault

signal for each function in order to test the timing. In the event of an anomaly, the type of error

detected is indicated by the corresponding message (threshold or timing error). This sequence

is automatically repeated on all protection unit functions. Testing may be interrupted at any

time using the STOP button, thereby restoring the original conditions/settings of the

ABB SACE SACE PR010/T RH0025002 L2551 7/20 20

protection unit prior to testing. In the case of releases not equipped with internal bus, the user

must preset the protections before testing.

•Manual mode: this test may be performed on any type of protection. In this case, the user

must set all the protection parameters before testing. During manual testing, the user selects

the type of device to be tested from a menu, whereupon device protection functions and

thresholds are displayed so that the user can set the required test parameters. If the user selects

an intermediate threshold in relation to those actually available, the SACE PR010/T test unit

will automatically convert it to the highest one. The fault may be simulated either separately

or simultaneously on any combination of phases L1, L2, L3 and NE.

4.1.3 Communication functions test

The SACE PR010/T test unit can also test the serial communication circuits of the protection

releases.

4.2 Programming function

Using the SACE PR010/T test unit, the type of releases with internal bus mounted on ABB SACE

low voltage circuit breakers can be programmed.

You can also program all the protection function parameters (threshold, curve, interlock

parameters etc.). The parameter-programming function does not interrupt the normal operation of

the protection unit, although parameters cannot be set if a timing alarm is pending.

The SACE PR010/T test unit will not set parameters outside the permitted range.

A message is displayed at the end of programming to indicate that the parameters have been

successfully programmed.

Each operating parameter modified must first be confirmed before it is saved. In the event of a

programming error, simply press the ESC key to cancel the last entry/action.

4.3 Parameter reading function

If the SACE PR010/T test unit is connected to releases with internal bus, it is possible to read the

main parameters of the protection units.

At the user's express request and, subject to availability, the SACE PR010/T test unit can provide

information about the following:

• protection status (thresholds, alarms, trips etc.)

• circuit breaker status (number of operations, contact wear etc.)

• phase, neutral and earth fault current readings

• serial number and SW release (available on the "Information" menu page).

NOTE: The parameter reading function is permanently available, irrespective of

the protections and CB status.

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:

The following information is automatically indicated for each protection function tested:

• type of protection

• threshold selected

• curve selected

•phasetested

• test current

• estimated trip time

• measured trip time

• test results.

- unit serial number (Sr. Nr.)

- date and time of test

- operator name

Manually entered by user

- type of unit tested Automatically supplied for releases with

internal bus only.
