Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions
Test Ground Minimum Trip Values
1. Change the Form 5 control from an Alternate Profile to the Normal Profile (all three Profile LEDs are off). Disable Ground Trip Block (LED off).
2. Set KMET switch S4 to 100 milliampere range.
3.Set KMET Variac TR1 to zero.
4.Set KMET switch S2 to test fault position.
5.Verify the Form 5 phase minimum trip values are higher than the ground trip values.
6.Set KMET Phase Selector S5 to A.
7.Press the TRIP button on the display panel.
8.Press the CLOSE button on the display panel.
9.Slowly raise TR1 until Above Minimum Trip shows on Form 5 control. Control should trip out for load cur- rents above 50 milliamperes. Record values.
10.Repeat steps 4 – 9 for the Form 5 Alternate Profiles 1, 2, and 3. The control is programmed to trip out at 100 milliamperes on the Alternate 1, 2, and 3 Profiles.
Note: If Cold Load Pickup is activated (LED off), the control will trip on a time delayed TCC with two trips to lockout for 30 seconds after closing in the control, per the default Cold Load Pickup control settings.
Test Phase Timing
1.Set the Form 5 control to Normal profile (all Alternate Profile LEDs off).
2.Activate GROUND TRIP BLOCK (LED on). Ground Trip is blocked.
3.Set KMET Phase Selector S5 to phase A.
4.Set KMET switch S4 to 300 milliampere range.
5.Press the Form 5 trip switch once to lock out the Form 5 control.
6.Set KMET phase selector S3 to Control Response.
7.While holding the KMET Test Fault Current Switch S2 in the Calibrate position, adjust the fault current to 200 percent fault (100 X 2 or 200 milliamperes).
Note: On newer controls, applying fault current while the control is locked out will set the Recloser Malfunction LED. This will not affect testing. To clear, press the Reset Targets button after all tests are complete.
8.Press the TRIP button on the display panel.
9.Press the CLOSE button on the display panel.
10.Set KMET Fault Switch S2 to test fault current posi- tion. Record timing readings from the KMET time clock for all trips on the A 2X___ test sheet location.
11.Set KMET Test Set switch S4 to the 1A position.
12.Set KMET Phase Selector S5 to phase B.
13.Calibrate KMET fault current to 500 percent (100 X 5 or 500 milliamperes) using the KMET 1A range.
14.Press the TRIP button on the display panel.
15.Press the CLOSE button on the display panel.
16.Set KMET test set Fault Current Switch S2 to test fault current position. Record timings from the KMET test set for all trips on the B 5X ___ locations on the test sheet.
17.Set KMET Phase Selector S5 to phase C.
18.Calibrate KMET Phase Selector S5 to 1000% of fault (1000 milliamperes).
19.Press the TRIP button on the display panel.
20.Press the CLOSE button on the display panel.
21.Set KMET test set Fault Current Switch S2 to test fault current position. Record timings from the KMET test set for all trips on the C 10X ___ locations on the test sheet.
22.Repeat steps 2 – 21 for Alternate Profiles 1, 2, and 3. Note that the Phase minimum trip for the Alternate Profiles is 200 amps. The 200% fault will then be 400 milliamperes or .4 amp, the 500% fault will then be 1000 milliamperes or 1 amp, and the 1000% fault will then be 2000 milliamperes or 2 amps.
Test Ground Timing
1.Verify control is programmed for all default settings.
2.Disable GROUND TRIP BLOCK (LED off). Ground Trip is active.
3.Activate the Normal Profile (Alternate Profile LEDs off).
Note: When testing the ground trip timing circuit, the KMET test set applies a phase to ground fault to the Form 5 control. If the applied fault current exceeds the phase minimum trip value, the control may time out on the phase time current curve, which may be shorter than the proper ground time current curve. For this reason, the Form 5 phase minimum trip value should be increased to a higher value while testing Form 5 ground trip time current curves.
4.Increase the Form 5 phase minimum trip value to 1600 amperes.
5.Set KMET Test Set switch S4 to the 300 milliampere position.
6.While holding the Fault Current Switch S2 in the Cali- brate position, adjust the fault current to 200 percent fault (50 X 2 or 60 milliamperes).
7.Press the TRIP button on the display panel.
8.Press the CLOSE button on the display panel.
9.Set KMET test set Fault Current switch S2 in the test fault current position. Record timings from the KMET test set for all trips on the G 2X ___ locations on the test sheet.
10.Calibrate KMET fault current to 500 percent, (50 X 5 or 250 milliamperes).
11.Press the TRIP button on the display panel.
12.Press the CLOSE button on the display panel.
