Type MET electronic recloser control tester operating instructions
Shipment and acceptance
This test set is completely assembled. inspected, adjusted,
and tested at the factory. It is in good condition when
accepted by the carrier for shipment. Upon receipt, inspect
the test set thoroughly for damage and loss of parts
incurred during shipment. If damage or loss is discovered,
file a claim immediately with the carrier.
Description
The Eaton Cooper Power series Type MET electronic
recloser control tester (Figure 1) is designed specifically for
testing Type ME Form 2, Form 3, Form 3A, Form 4A and
Form 4C controls. The tester has the capability to check
the following:
1. Battery voltage (load and no load).
2. Battery charge and discharge rates.
3. Minimum-trip current, phase and ground (low range to
5 amp ground).
4. Operating sequence.
5. Control response time (phase and ground trip).
6. Reclosing time.
7. Reset time.
8. Electrical operation of recloser.
9. Various accessory functions through simulation of the
conditions under which they operate.
The self-contained unit is compactly packaged in a sturdy,
weather-proof carrying case with a detachable front cover.
Cables for connecting the recloser, electronic control, and
control battery to the tester are supplied with the tester and
stored in the carrying case along with spare fuses and bulbs
for panel lights. No other external equipment or accessories
are required when using the tester.
The tester can check operation of the electronic recloser
control and also can check the electrical operation of
the recloser (provided reclosing power is available at the
recloser). However, the control cannot operate the recloser
through the tester.
A recloser-simulator circuit is built into the tester to simulate
recloser operation (indicated by red and green lights on
the tester panel) and to simulate the response time of the
recloser mechanism to trip and close signals. The recloser
simulator provides a 2-1/2-cycles time delay to duplicate
the interrupting time of a Type RE recloser in response to
a trip signal from the control when recloser clearing time
tests are being conducted. It also provides a time delay
of approximately 30 cycles to duplicate the response time
of a Type RE or WE recloser to a reclosing signal from the
control when reclosing time tests are being conducted.

Instrumentation
1. DC METER
Edgewise panel meter with two-in. horizontal scale;
accuracy ±5% full scale; panel switched ranges:
0—4/40 mA, 0—40 V.
2. AC METER
Edgewise panel meter with two-in. horizontal scale;

otee:
N
Jacks on the tester panel provide the means for
connecting an external ammeter into the circuit. They
may be used for calibrating the internal meter or it
different scales or greater accuracy is desired.
3. TIMER
LCD readout digital clock timer, 000.000 to 999.999
seconds in 0.001-second increments; with manual and
automatic reset; accuracy ±0.001% ±1 digit.
Interconnecting cables
1. 15-ft cable for connecting electronic control to tester.
2. 15-ft extension cable for connecting end of recloser
cable to tester.
3. 15-ft cable for directly connecting control-panel battery
terminals to tester.
otee:
N
Connector terminations on all cables are polarized to
assure proper interconnection An internal buzzer will
sound it a mismatch between grounds on the ME
control and the MET tester exists.
