1 OPERATING INSTRUCTIONS MN280067EN July 2017Type MET electronic recloser control tester operating instructionsShipment and acceptanceThis test set is completely assembled. inspected, adjusted,and tested at the factory. It is in good condition whenaccepted by the carrier for shipment. Upon receipt, inspectthe test set thoroughly for damage and loss of partsincurred during shipment. If damage or loss is discovered,file a claim immediately with the carrier.DescriptionThe Eaton Cooper Power series Type MET electronicrecloser control tester (Figure 1) is designed specifically fortesting Type ME Form 2, Form 3, Form 3A, Form 4A andForm 4C controls. The tester has the capability to checkthe following:1. Battery voltage (load and no load).2. Battery charge and discharge rates.3. Minimum-trip current, phase and ground (low range to5 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 theconditions 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, andcontrol battery to the tester are supplied with the tester andstored in the carrying case along with spare fuses and bulbsfor panel lights. No other external equipment or accessoriesare required when using the tester.The tester can check operation of the electronic reclosercontrol and also can check the electrical operation ofthe recloser (provided reclosing power is available at therecloser). However, the control cannot operate the recloserthrough the tester.A recloser-simulator circuit is built into the tester to simulaterecloser operation (indicated by red and green lights onthe tester panel) and to simulate the response time of therecloser mechanism to trip and close signals. The reclosersimulator provides a 2-1/2-cycles time delay to duplicatethe interrupting time of a Type RE recloser in response toa trip signal from the control when recloser clearing timetests are being conducted. It also provides a time delayof approximately 30 cycles to duplicate the response timeof a Type RE or WE recloser to a reclosing signal from thecontrol when reclosing time tests are being conducted.SpecificationsInput115 Vac, 50/60 Hz, single phase (fused for two amp) with15-ft power cord and a three wire grounding plug.240 Vac 50/60 Hz, single phase (fused for one amp) with 15-ftpower cord with no plug attached, is available as an accessory.Output0—3000 mA continuously adjustable from front panel of tester.Instrumentation1. DC METEREdgewise panel meter with two-in. horizontal scale;accuracy ±5% full scale; panel switched ranges:0—4/40 mA, 0—40 V.2. AC METEREdgewise panel meter with two-in. horizontal scale;accuracy ±5% full scale; panel switched ranges:0—30/100/ 1000/3000 mA.otee:N Jacks on the tester panel provide the means forconnecting an external ammeter into the circuit. Theymay be used for calibrating the internal meter or itdifferent scales or greater accuracy is desired.3. TIMERLCD readout digital clock timer, 000.000 to 999.999seconds in 0.001-second increments; with manual andautomatic reset; accuracy ±0.001% ±1 digit.Interconnecting cables1. 15-ft cable for connecting electronic control to tester.2. 15-ft extension cable for connecting end of reclosercable to tester.3. 15-ft cable for directly connecting control-panel batteryterminals to tester.otee:N Connector terminations on all cables are polarized toassure proper interconnection An internal buzzer willsound it a mismatch between grounds on the MEcontrol and the MET tester exists.AC power cord15-ft three-wire power cord with groundable power plugCarrying caseTester is packaged in a sturdy Formica covered carrying casewith removable front cover; has provisions for storing powercord, interconnecting cables. and spare fuses and bulbs.Dimension9-1/2 in. high, 21 in. wide, 13-1/4 in. deep overall.Weight (approximately )Net 33 Ib; shipping 37 Ib.
