Type MET electronic recloser control tester operating instructions
7. Move the Manual Control switch to CLOSE and release.
The simulator will close in approximately 3/4 second;
green OPEN light off, red CLOSED light on.
8. Reduce the Fault-Current Adjust Control TR1 to zero.
Set the Fault Current switch S2 to TEST.
9. Advance the Fault-Current Adjust control TR1 until the
control trips; immediately turn TR1 to zero before the
control recloses the MET Tester. The clock will start
running when the control recloses the MET tester.
10. As soon as the sequence relay resets to home
(Form 3 family controls), or the display return to “0”
(Form 4 family controls), place the Fault Current switch
S2 to OFF and record the time. The time indicated is
the reset time.
11. Return the control and tester settings to the INITIAL
CONDITIONS specified at the beginning of the
CONTROL TESTS, making sure the electronic control is
reprogrammed to its operating settings.
Recloser tests
The control cannot operate the recloser through the Type
MET electronic recloser control tester. However, circuitry is
provided to trip and close the recloser from the tester with
the control battery (providing closing-coil or closing-motor
energy is available at the recloser).
Initial conditions
Control
Battery connected and control in lockout (verify with Lockout
Test switch and Lockout Indicator lamp).
WARNING
Hazardous voltage . Solidly ground all equipment . Failure
to comply can result in death, severe personal injury,
and equipment damage .
T223 .2
Tester
All switches and controls in their OFF or extreme
counterclockwise position, except Test Selector switch S6 in
BATT. VOLTS—(40V).
otee:
N
The tester need not be energized for this test.
However, the power-line cord should be plugged
into a three-wire grounded outlet to ground the front
panel of the tester. See CAUTION at beginning of
OPERATING PROCEDURES section.
Recloser
Closing power provided at the recloser (either line potential
for solenoid closing or 240 Vac for motor closing).
Test procedure
1. Plug the battery-test cable, furnished with the tester,
into the BATT. TEST TERMINALS on the tester and the
battery terminals on the control.
2. Connect the elbow plug of the recloser extension-
test cable, furnished with the tester, to the Recloser
receptacle on the tester and the other end to the
recloser control cable.
3. The recloser can now be closed and tripped by
operating the Recloser Test switch S8 either to CLOSE
or OPEN. The battery voltage can be monitored on the
Dc meter during these operations.
