Target readback status test
Setup
1.
Place the Phase Instantaneous Trip switch on the
control board into ON position.
Test procedure
1.
Place the 60 A Fault Current toggle switch into the ON
position. Place all of the other Fault Current switches
into the OFF position.
2. Press and release the Control Test button to initiate
flow of simulated fault current to the control.
3. After the A-Phase flux-shift tripper operates, verify
continuity between pins 8 and 9 of the Customer
Connections Terminal Block.
4. Using a jumper wire, temporarily jumper pins 13 and
14 of the Customer Connections Terminal Block. This
will reset all of the fault targets. Verify non-continuity
between pins 8 and 9 of the Customer Connections
Terminal Block.
5. Place the Phase Select switch into the B-PHASE
position.
6. Press and release the Control Test button to initiate
flow of simulated fault current to the control.
7.
After the B-Phase flux-shift tripper operates, verify
continuity between pins 8 and 10 of the Customer
Connections Terminal Block.
8. Using a jumper wire, temporarily jumper pins 13 and
14 of the Customer Connections Terminal Block. This
will reset all of the fault targets. Verify non-continuity
between pins 8 and 10 of the Customer Connections
Terminal Block.
9. Place the Phase Select switch into the C-PHASE
position.
10. Press and release the Control Test button to initiate
flow of simulated fault current to the control.
11. After the C-Phase flux-shift tripper operates, verify
continuity between pins 8 and 11 of the Customer
Connections Terminal Block.
12. Using a jumper wire, temporarily jumper pins 13 and
14 of the Customer Connections Terminal Block. This
will reset all of the fault targets. Verify non-continuity
between pins 8 and 11 of the Customer Connections
Terminal Block.
13. Place the Ground Trip Block switch into the OFF
position (TPG only).
14. Set the minimum trip levels on A-phase, B-phase, and
C-phase to 690 A.
15. Reset the flux-shift tripper.
16. Press and release the Control Test button to initiate
flow of simulated fault current to the control.
17. After all three of the flux-shift trippers operate, verify
continuity between pins 8 and 12 of the Customer
Connections Terminal Block.
18. Using a jumper wire, temporarily jumper pins 13 and
14 of the Customer Connections Terminal Block. This
will reset all of the fault targets. Verify non-continuity
between pins 8 and 12 of the Customer Connections
Terminal Block.
19. Place the Ground Trip Block switch into the OFF
position (TPG only).
20. Reset the flux-shift tripper.
Ground trip block enable test
1.
Verify non-continuity between pins 8 and 17 of the
Customer Connections Terminal Block.
2. Using a jumper wire, jumper pins 15 and 16 of the
Customer Connections Terminal Block.
3. Verify continuity between pins 8 and 17 of the
Customer Connections Terminal Block.
4. Remove the jumper wire between pins 15 and 16 of
Customer Connections Terminal Block.
5. Verify non-continuity between pins 8 and 17 of the
Customer Connections Terminal Block.
Remote trip test
Setup
1.
Place the remote trip power selector switch into the
125 Vdc/120 VAC position.
2. Using a power cord, apply 120 VAC to pins 6 and 7
of the Customer Connections terminal block located
upon the SCADA board. Connect the hot wire to pin 6.
Connect the neutral wire to pin 7.
IMPORTANT
The TPG/SCADA board accessory is a polarity dependent
device. Do not connect a hot wire to the terminal 7 of the
customer connections terminal block of the SCADA board.
Failure to comply will result in damage to the SCADA board.
Refer to the connections decal found within the control
enclosure for additional information.
3. Plug the other end of the power cord into the
accessory outlet on the VFI tester.
Test procedure
1.
Reset the flux-shift trippers on VFI tester.
2. Using a jumper wire, jumper pins 1 and 4 of the
Customer Connections Terminal Block.
3. Using another jumper wire, momentarily jumper pins
5 and 15 of the Customer Connections Terminal Block.
The A-Phase flux-shift tripper on the VFI tester should
operate.
