FORM 5 CONTROL DEFAULT TEST PROCEDURE

!

CAUTION: Equipment misoperation. Do not con-

nect this control to an energized recloser until all

 

control settings have been properly programmed and verified. Refer to the programming information for this control. Failure to comply can result in control and recloser misoperation, equipment damage, and per-

sonal injury.

G110.3

IMPORTANT: The Form 5 recloser control can be taken out of service for testing and placed back into service without de-energizing its recloser and interrupting the system. However, during the time the control is out of service, the recloser is inoperative.

Test Battery Circuitry

IMPORTANT: The Battery Test procedure requires large current drain. Overuse of this procedure will drain the battery.

1.Press BACK button on display panel until Battery Test Screen 31 appears.

2.Record values for all settings.

3.Press CHANGE button on the display panel.

4.Press BATTERY TEST button on display panel.

5.Record values for all readings.

IMPORTANT: The Form 5 DC NOVA control can not be tested with the standard Kyle MET Tester. A junction box accessory for the MET tester is availble for testing the Form 5 DC NOVA control.

Use this procedure to test the Form 5 control with factory default control settings. Follow all cautions and warnings in these service instructions.

Before installation on an active feeder, the Form 5 control ’s final control settings must be fully tested using an appropriate test procedure. The Form 5 Control Default Test Sheet follows these instructions. The Form 5 Control Default Test Sheet Optimal Values gives the optimal values for the test results.

When performing these tests, change the Form 5 panel settings by first pressing the CHANGE button and then pressing the button of the function to be changed.

Initial Settings

1.Apply 120 (240) Vac to the control phase B and neu- tral for standard controls.

2.Plug in battery.

3.Verify control is programmed for all default settings.

•Phase Minimum Trip is set to 100 amps.

•Ground Minimum Trip is set to 50 amps.

4.Disable Sequence Coordination in normal profile using personal computer (PC).

5.Activate COLD LOAD PICKUP BLOCKED (LED is on) on Form 5 display panel.

6.Activate GROUND TRIP BLOCK (LED is on) on Form 5 display panel.

Test Phase Minimum Trip Values

1.Verify Ground Trip Block LED is on.

2.Set KMET Phase Selector S5 to A.

3.Set KMET switch S4 to 300 milliampere range.

4.Set KMET Variac TR1 to zero.

5.Set KMET switch S2 to test fault current position.

6.Press the TRIP button on the display panel.

7.Press the CLOSE button on the display panel.

8.Slowly raise TR1 until Above Minimum Trip LED is on, on display panel. Control should trip out quickly for load currents above 105 milliamperes. Record value.

9.Repeat steps 4 – 8 for phases B and C (move KMET S5 to B, then C).

10.Change Form 5 control from Normal Profile to Alter- nate Profile 1.

11.Verify Cold Load Pickup Blocked (LED is on) on the display panel.

12.Repeat steps 2 – 9 for Form 5 Alternate Profiles 1, 2, and 3. The control is programmed to trip out at 200 milliamperes on the Alternate 1, 2, and 3 Profiles.

Note: If Cold Load Pickup LED is off, the control will trip on a time delayed Time Current Curve with two trips to lockout for 30 seconds after closing in the control, per the default Cold Load Pickup control settings.

Note: If Alternate Profiles 1, 2, and 3 have the sequence coordination function enabled while testing the Form 5 control minimum trip values, it may result in the control skipping past the fast TCC curves during the test for minimum trip. The control will then lock out on the delayed TCC curves.

Note: If the Form 5 control has Switch Mode rather than Profile 3, the control will indicate current Above Minimum Trip, but will not trip out.
