Adapter Panel M-2299

Adapts M-2001 Series Digital Tapchanger Control

to Replace Toshiba TB-R800 Regulators

CONTROLS

• Connects easily to the M-2001 Series Digital Tapchanger Control using mounting screws and 24-pin connector

• Provides direct mechanical replacement of the existing regulator control

• Provides built-in CT shorting protection when the M-2001 Series Digital Tapchanger Control is removed

The M-2299 is an adapter panel which, when combined with the M-2001 Series Digital Tapchanger Control, provides convenient direct replacement of Toshiba TB-R800 regulators. The M-2299 mounts into the control cabinet using the same two hinge pins which

must be saved

from the original regulator.

Interface

External connections are made via a wiring harness that connects from a fifteen-position terminal block to the ”BT” terminal block on the existing control cabinet. An additional terminal block provides access to auxiliary functions, including self-test alarm, user-programmable alarm, auto disable and manual raise/ lower.

Features

Separate fuses for test terminal, voltage sensing and motor power are on the front panel. Spare fuses for each are in the fuse holder.

Binding posts on the front panel allow easy connections for test procedures.

RAISE/OFF/LOWER, AUTO/OFF/MANUAL, and VOLTAGE SOURCE switches and NEUTRAL LIGHT are standard.

NEUTRAL LIGHT will light to indicate that the regulator is in the neutral position, for those regulators equipped with a circuit for this purpose.

Testing Specifications

High Voltage: All input and output terminals will withstand 1500 V ac rms to chassis or instrument ground for one minute with a leakage current not to exceed 25 mA, for all terminals to ground.

WARNING

DANGEROUS VOLTAGES, capable of causing death or serious

injury, are present on the external terminals and inside the equipment. Use extreme caution and follow all safety rules when handling, testing or adjusting the equipment. However, these internal voltage levels are no greater than the voltages applied to the external terminals.

DANGER! HIGH VOLTAGE

– This sign warns that the area is connected to a dangerous high voltage, and you

must never touch it.

PERSONNEL SAFETY PRECAUTIONS

The following general rules and other specific warnings throughout the manual must be followed during application, test or repair of this equipment. Failure to do so will violate standards for safety in the design, manufacture, and intended use of the product. Qualified personnel should be the only ones who operate and maintain this equipment. Beckwith Electric Co., Inc. assumes no liability for the customer’s failure to comply with these requirements.

– 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 servicing equipment in a test area, the Protective Earth Terminal must be attached to a separate ground securely by use of a tool, since it is not grounded by external connectors.

Do NOT operate in an explosive environment

Do not operate this equipment in the presence of flammable or explosive gases or fumes. To do so would risk a possible fire or explosion.

Keep away from live circuits

Operating personnel must not remove the cover or expose the printed circuit board while power is applied. In no case may components be replaced with power applied. In some instances, dangerous voltages may exist even when power is disconnected. To avoid electrical shock, always disconnect power and discharge circuits before working on the unit.

Exercise care during installation, operation, & maintenance procedures

The 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 personnel safety procedures are carefully followed. Exercise due care when operating or servicing alone.

Do not modify equipment

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

PRODUCT CAUTIONS

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

Avoid static charge

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

Use caution when measuring resistances

Any attempt to measure resistances between points on the printed circuit board, unless otherwise noted in the Instruction Book, is likely to cause damage to the unit.

M-2299 Application Guide

The Beckwith Electric M-2299 Adapter Panel, used in conjunction with the M-2001 Series Digital Tapchanger Control, uses modern electronic digital design and digital processing circuitry to achieve an overall stability and resolution unattainable with electromechanical and analog design tapchanger controls. CMOS semiconductors are used throughout the design.

 NOTE: The hinge pins

must be saved

from the original control. The BT terminal blocks remain in the control cabinet.

1.0 Description

Standard Features

The M-2299 Adapter Panel, with the M-2001 Series Digital Tapchanger Control, provides a solid-state voltage control relay designed to directly replace the Toshiba TB-R800 control. The combination of the Tapchanger Control and Adapter Panel includes the following features:

1. Voltage waveform sampling and digital processing circuitry ensure accurate rms voltage sensing in the presence of distortion on the input voltage and current.

2. Accuracy exceeds the ANSI/IEEE C57.15-1986 Class 1 specification over the temperature range of –40° C to +70° C.

4. Separate motor power, test terminal and voltage sensing fuses are easily changed from the front panel and spare fuses are provided in their respective fuseholders.

5. Easily tested by use of the following:

a. VOLTAGE SOURCE switch

disconnects the voltage transformer input and connects the VOLTAGE IN binding posts to the voltage input and motor circuit.

b. VOLTAGE IN binding posts on the

front panel allow application of a 120 V rms nominal voltage to the unit for test procedures.

c. METER OUT binding posts on the

front panel allow reading of the input voltage when used in conjunction with the BIAS TEST VOLTAGE screen of the M-2001 Series Digital Tapchanger Control.

d. RAISE and LOWER band edge LEDs

on the M-2001 Tapchanger Control indicate when the input voltage is outside the voltage band.

6. NEUTRAL light illuminates when the regulator is in the neutral tap position.

7. AUTO/OFF/MANUAL switch allows manual operation of the control.

3. Input and output circuits are protected against system transients. Units pass all requirements of ANSI/IEEE C37.90.11989, which defines surge withstand capability. All input and output terminals will withstand 1500 V ac rms to chassis or instrument ground for one minute with a leakage current not to exceed 25 mA, from all terminals to ground. Input and output circuits are electrically isolated from each other, from other circuits and from ground.
