7. ACCEPTANCE TESTS
7-12
BUS1000 Busbar Protection
GEK-98514B
7.12.3. ALARM UNIT CALIBRATION
In order to carry out this test, remove the jumpers in the stabilization resistors.
Apply current through the same terminals as in the previous tests and check for every unit and phase the
pickup values of the alarm units and their operation times.
The operation values will be approximately 28 mA and the operation time will be 10 s. If not, adjust with the
P1 potentiometer of the alarm board.
NOTE
: The terminals to be used for the STOP of the chronometer depend on the type and construction of
the equipment.
Double bus. Bus A: terminals X35 - X36.
Double bus. Bus B: terminals X43 - X44.
The obtained value will be recorded in the corresponding box.
7.12.4. OVERCURRENT UNITS AND BREAKER FAILURE CALIBRATION
7.12.4.1.Operation Level Calibration
Set the operation level adjustment of the breaker failure unit to 0.9A Set the unit operation time adjustment to
the minimum (0.1 s).
Simulate the pickup of the unit and apply 0.9 A current by adjusting with potentiometer P1 of the board so
that the unit may operate with that current (check with an oscilloscope that there are no pulses in D22
anode). Remember that it is timed.
Check the rest of the adjustable values. Operation time calibration.
Set the operation time adjustment of the breaker failure unit to 0.5 s and that of the operation level to 0.2 .
Apply 0.5 A and adjust with the P5 potentiometer of the board so that the unit may operate en 0.5 s.
Check the rest of the adjustable values.
7.12.4.2. Overcurrent Unit Calibration
Set the adjustment of the overcurrent unit to 0.9 . Apply 0.9 A and adjust with the P2 potentiometer of the
board so that the unit may operate with that value.
Check the rest of the adjustable values.
NOTE
: Terminals for chronometer stop.
First step: X25-X26
Second step: X27-X28
Check that the model or models indicated in the plates match the data given in the order. Unpack the
equipment and check there are no broken parts and no signs that the system has suffered any damage
during transportation.
