M-0390 Specification

Breaker Close Relay• Two form A output contacts rated to make 10 A at up to 250 V dc; interrupt 0.9 A, 125 V dc or

0.4 A at up to 250 V dc inductive load. Open contacts will withstand 1500 V ac for 1 minute.Contacts to ground will withstand 1500 V ac for 1 minute. Contacts may be paralleled to make 20A at up to 250 V dc.

• One normally open output contact rated to make 10 A at up to 250 V dc; interrupt 0.9 A, 125 V dcor 0.4 A at up to 250 V dc inductive load. Open contacts will withstand 1500 V ac for 1 minute.Contacts to ground will withstand 1500 V ac for 1 minute. A normally closed light duty contact isprovided that opens when either the line or bus is above 80 V ac 10 V. The contact closeswhen both the line and bus voltage drop below 50 V ac 10V. The light duty contact is rated at3 A at up to 240 V ac.

Response TimeThe M-0390 will close the breaker with proper phase angle only after the time set by the TIME LIMITcontrol, assuming the ΔF is within limits. After the timer has timed out, the M-0390 will respond to correctvoltage conditions in approximately 0.2 sec. In closing on dead line or dead bus, the phase and frequencyconditions are ignored so that the unit will close upon a voltage below set threshold in approximately 1.5sec.

Status Relay ContactsThese are light duty, form C contacts rated for 3 A at 120 V ac noninductive load. They are intendedprimarily for status interrogation by supervisory and may be used to light local lights.

Phase Status: Phase angle is within the limit setting.

Voltage Status: Line and Bus voltages are within the limit settings.

ΔΔΔΔΔF Status: ΔF is within the limit setting.

Dead Line/Dead Bus Status Option: See BREAKER CLOSE RELAY option 2 above.

Analog Output OptionsSCADA-compatible analog outputs are provided that can be connected for either voltage or currentoutputs, and may be used as transducer outputs or for interrogation of the unit while in operation.

Phase• 0 to 10 V dc = 0 to 180°, accuracy 3°. Load: 5 K or greater.

• 0 to 1.0 mA dc = 0 to 180°, accuracy 3°. Load: 10 K or less.

Other voltage/current ranges can be set by external precision resistors.

Line/Bus Voltage• 0 to 7.5 V dc = 0 to 150 V rms, accuracy 5% of full scale. Load: 3 K or greater.

• 0 to 1.0 mA dc = 0 to 150 V rms, accuracy 5% of full scale. Load: 10 K or less.

Other voltage/current ranges can be set by external precision resistors.

NOTE: The Analog Outputs are not isolated from each other. A common zero volt reference (AnalogCommon) is used for all analog outputs.

M-0292 Test Cable Set OptionThe M-0292 Test Cable Set allows the Power Supply, Phase Verifier, and Voltage Verifier / SynchronizerBoards of the M-0390 to be tested either in the field or in the laboratory. The cable set allows the boards tobe physically removed from the case while remaining electrically connected for testing.

Field TestingTwo OPERATE/TEST switches, located on the M-0390 front panel, internally disable the Output Relayand disconnect the Bus and Line V.T. inputs when in the TEST position. This isolates the V.T. inputs of theM-0390 from the external wiring and ensures that the Output Relay Contact will not close while the unit isbeing tested. The M-0390 can then be checked by applying 120 V ac nominal Line and Bus inputs at therespective jacks on the front panel.

CalibrationNo circuit calibration is required; complete, solid-state design has no circuit calibration controls.

ReliabilityThe most advanced and stable solid-state components are used to achieve an accuracy and reliability ofservice not usually available for this class of relay. The reliability is enhanced by the basic stability of thecircuits; no temperature compensation is used.

Transient ProtectionInput and output circuits are protected against system transients. The M-0390 will exhibit no componentfailure or false commands when subjected to the requirements of ANSI/IEEE C37.90.1-1989, whichdefines oscillatory and fast transient surge withstand capability. All inputs and outputs will withstand1500 V ac to chassis or instrument ground for one minute. Voltage inputs are electrically isolated fromeach other, from other circuits, and from ground.

All faces of the relay, with the chassis solidly grounded, have been exposed to Radio Frequency Immunitytesting and have successfully passed with a field intensity of 20 volts per meter at typical utility frequenciesof 144 MHz, 148 MHz, 438 MHz, and at 450 MHz.

EnvironmentalTemperature Range: Stated accuracies are maintained from –40° to +80° C; analog output signals to +60°C.

Humidity: Stated accuracies are maintained at up to 85% relative humidity (non-condensing).

Fungus Resistance: A conformal printed circuit board coating inhibits fungus growth.

PhysicalSize and Mounting: The unit is designed for semiflush panel mounting, compatible with G.E. type S1 andWestinghouse type FT-21 drawout relay cases. Refer to the Application Guide for specific dimensions. Atransparent cover is supplied with the unit.

Approximate Weight: 12 lb (5.5 kg).

Approximate Shipping Weight: 14 lb (6.4 kg).

– This sign means that you should refer to the corresponding section of the operation

manual for important information before proceeding.

Always Ground the Equipment

To avoid possible shock hazard, the chassis must be connected to an electrical ground. When servicingequipment in a test area, the Protective Earth Terminal must be attached to a separate ground securelyby use of a tool, since it is not grounded by external connectors.

Do NOT operate in an explosive environmentDo not operate this equipment in the presence of flammable or explosive gases or fumes. To do so wouldrisk a possible fire or explosion.

Keep away from live circuitsOperating personnel must not remove the cover or expose the printed circuit board while power is ap-plied. In no case may components be replaced with power applied. In some instances, dangerous volt-ages may exist even when power is disconnected. To avoid electrical shock, always disconnect power anddischarge circuits before working on the unit.

Exercise care during installation, operation, & maintenance proceduresThe equipment described in this manual contains voltages high enough to cause serious injury or death.Only qualified personnel should install, operate, test, and maintain this equipment. Be sure that all per-sonnel safety procedures are carefully followed. Exercise due care when operating or servicing alone.

Do not modify equipmentDo not perform any unauthorized modifications on this instrument. Return of the unit to a BeckwithElectric repair facility is preferred. If authorized modifications are to be attempted, be sure to followreplacement procedures carefully to assure that safety features are maintained.

PRODUCT CAUTIONSBefore attempting any test, calibration, or maintenance procedure, personnel must be completely familiarwith the particular circuitry of this unit, and have an adequate understanding of field effect devices. If acomponent is found to be defective, always follow replacement procedures carefully to that assure safetyfeatures are maintained. Always replace components with those of equal or better quality as shown in theParts List of the Instruction Book.

Avoid static chargeThis unit contains MOS circuitry, which can be damaged by improper test or rework procedures. Careshould be taken to avoid static charge on work surfaces and service personnel.

Use caution when measuring resistancesAny attempt to measure resistances between points on the printed circuit board, unless otherwise notedin the Instruction Book, is likely to cause damage to the unit.
