TESTING AND TROUBLESHOOTING

!

CAUTION: Equipment misoperation. Do not

connect 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, equip-

ment damage and personal 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.

Testing an Installed Control

The following tests to determine initial operation of the Form 5 control can be performed while connected to an operating recloser. These are the only tests performed on an installed, operating control. All other tests described in this Testing and Troubleshooting section require the Form 5 control to be removed from service, connected to a bypassed recloser, or tested at a location where the proper testing equipment is available.

1.Wake-up the operator panel display by pressing the CHANGE/LAMP TEST button on the control operator panel.

2.Scroll through the LCD display messages as described in the LCD Display Messages section of these instructions. Refer to Form 5 Control operator panel section of this manual.

Check the operational values for currents, voltages, and other metering information.

3.Check that the LED for AC power is illuminated on the control operator panel. This indicates the presence of AC power.

4.Test battery operation, using the procedures described in the Battery Test Procedure section of these instructions.

Check CPU Status

Check the operating status of the CPU module. Open the cabinet door and locate the LED indicator (Figure 40).

The LED indicator on the CPU module should flash at a rate of one flash per second for normal 60 Hz operation (slightly faster for 50Hz).

Testing With Type MET Tester

The Kyle Type MET Electronic Recloser Control Tester (Figure 41) is used for testing the Form 5 control.

The MET Tester is completely self-contained, includes all necessary metering and interconnecting cables, and is capable of performing all required checks and tests from a simple verification of operation to a complete verification

of all operating parameters. Refer to Service Information S280-76-1 Type MET Electronic Recloser Control Tester Operator Instructions for proper setup and use of the MET tester. Refer to Form 5 Control Default Test Procedure section of this manual for specific tests requiring the KMET Tester.

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

IMPORTANT: When the control is open and current is present, the Trip Fail detection circuit in the Form 5 control will activate when the Kyle Type MET tester CALIBRATE switch is ON. Depress and hold the RESET TARGET keypad on the control for 3 seconds to reset the condition.
