Adjustable from –72 V to +72 V in 1 V increments. Z compensation available with adjustment of voltage raise from 0 V to +72 V, in increments of 1 V.Time Delay: Definite; adjustable from 1 second to 360 seconds, in 1 second increments. Inverse; adjustable from 1 second to 360 seconds, in 1 second increments.InterTap Time Delay: Used to introduce time delay between tap operations when control is in sequential mode; adjustable from 0 to 60 seconds in 1.0 second increments. Counter input required.Selectable Outputs: Continuous or pulsed. Normally, an output (raise or lower) signal is maintained when the voltage remains outside the band. A pulsed output length is programmable from 0.2 to 12 seconds, in increments of 0.1 second.Reverse Power Operation: If Motor Direct Drive KeepTrack™ is applicable, unit may be set to "Block", "Regulate Forward (Ignore)", "Regulate Reverse", "Return to Neutral", "Regulate Reverse (Measured)" or "Distributed Generation." The Regulate Reverse feature allows separate setpoints and regulation in the reverse direction without the installation of source-side VTs. Distributed Generation allows alternate LDC R and X values to be applied to the control when reverse power is detected. If Motor Direct Drive KeepTrack is disabled, then " Regulate Reverse (Measured)", "Ignore" and "Block" modes are available. Regulate Reverse (Measured) allows the control to switch it’s voltage sensing input from a load side VT to a source side VT if one is available and operate in Reverse Power Mode using that input.CT to VT Phasing Correction: Adjustable from 0° to +330° in 30° increments.Load Overcurrent Tapchange Inhibit: Adjustable from 50 mA to 640 mA of line current for 200 mA CT or 0.2 A to 3.2 A for 1 A CT display and 1.2 A to 16.0 A for 5 A CT display. External auxiliary CT required for 1.0 A and 5 A CT inputs.Voltage Limits, Tap Position Limits, and Runback: Overvoltage and Undervoltage limits are independently adjustable from 95 V to 135 V in 0.1 V increments. Upper and lower tap position limits may be set by user, with tap position knowledge active. An adjustable dead band (above the overvoltage limit) of 1 V to 4 V is available, which is used to set the runback limit.Voltage Reduction: Three independent steps, each adjustable from 0% to 10% in 0.1% increments of the bandcenter setpoint can be actuated from the dedicated front-panel pushbutton or through contact inputs. Voltage Reduction can be disabled locally and remotely if desired.Normalizing Voltage: A Normalizing Voltage Multiplier with a range of 0.80 to 1.20 is available to be applied to Meter Out Voltage and displayed in real time as Normalizing Voltage. The purpose of the Normalizing Voltage is to allow the user to overcome differences in the ratio of the PT that the Load Voltage input is using versus the PT the end user or other metering methods are using.Inhibit of Auto Tapchange: Blocks automatic tapchanger operation in response to external contact closure or software setting.Non-Sequential/SCADA Block Operation: Non-sequential/SCADA Block blocks automatic tapchanger operation in response to external contact closure or software setting. Non-sequential/SCADA Block input also resets the time delay upon momentary external contact closure at the non-sequential input.Paralleling Methods:Circulating Current: The circulating current method is standard, and may be implemented using separate balancing equipment such as the Beckwith Electric M-0115A Parallel Balancing Module. Consult with factory for use with existing external master-follower circuitry.?VAR® (optional): When selected, the ?VAR1 method may be implemented by using separate balancing equipment such as the M-0115A Balancing Module. The ?VAR2 method does not require the use of the M-0115A Balancing Module and is only applicable when paralleling two transformers.For all methods of paralleling except ?VAR2, overcurrent protection, such as that provided by the M-0127A Overcurrent Relay, is recommended.–5–M-2001D Digital Tapchanger ControlMaster/Follower(Optional): The optional Master/Follower feature employs the GOOSE messaging of the IEC 61850 protocol to provide peer to peer communications.?VAR3 (future): Paralleling achieved through communication using IEC 61850 GOOSE messaging.VT Ratio Correction: VT correction from –15 V to +15 V in 0.1 V increments. Self-Test Alarm Output Contacts: Alerts operator to loss of power or malfunction of control. When the control is configured for SCAMP Pushbutton Auto/Manual Switch Type, this output is not available.User-Programmable Alarm Contacts: Alerts operator to one or more of the following system conditions: • Communication Block • Block Raise Limit • Block Lower Limit • Backup Fail (if purchased) • Voltage Reduction • Reverse Power Flow • Line Current Limit • Individual Tap Wear • Tap Block Raise • Tap Block Lower • LDC/LDZ • Op Count Signal • Abnormal Tap • VAr Bias Lag • VAr Bias LeadTap Position KnowledgeCurrent Loop Method: The optional M-2025D Current Loop Interface Module receives a signal from a position transducer and provides an input to the M-2001D through a six pin port. Single-Phase Regulators: In most applications, tap position information can be maintained by means of Motor Direct Drive KeepTrack™ logic.Operations Counter: A software counter increments by one count per either an open/close/open contact operation (X1) or an open/close or close/open contact operation (X2), and is preset by the user. A Count Window mode registers any activity as a valid input within the count window time setting.Resettable Operations Counter: A second software counter, similar to the Operations Counter, which may be reset by the user.Tap Position Record: Provides a record of the number of times each tap position has been passed through. The tap position record can be reset by the user.Tap Wear Settings: Provides the capability to determine tap wear in a regulator's tap change mechanism.Auto/Manual Switch Status: Provides the user with the Auto/Manual switch position status through the Comm ports. When the M-2001D is configured for a switch status input, the switch status is read using the seal-in input on the control. When configured for Seal-in input, the switch status is read using the counter input.A or B Regulator Type: Allows the user to select the type of regulator being used to provide a more accurate source voltage calculation.SCADA HeartBeat: The purpose of the SCADA HeartBeat feature is to have two sets of settings for the control and switch between these two setting sets based on the presence or absence of SCADA communications (utilizing the DNP or optional IEC 61850 protocol) to the control. The SCADA HeartBeat feature can be enabled from TapTalk® Communications Software. There are four different types of SCADA HeartBeat modes that can be selected: • SCADA HeartBeat for transformer control applications (LTC) • SCADA HeartBeat for regulator control applications (Regulator) • Profile Switching – This mode allows the user to specify a different settings profile to operate by while communication is active • Profile Switching (GOOSE) – with the optional IEC 61850 protocolSCADA Remote Manual Mode: The purpose of the SCADA HeartBeat Remote Manual Mode is to provide a means for a SCADA system to place the unit in Remote Manual and perform Raise and Lower operations. As long as a Remote Manual Timer setting in the control is refreshed by the SCADA system before it times out, the control will stay in Remote Manual. If the timer times out, the control reverts to normal Automatic operation.VAr Bias: This feature is intended but not restricted for use with distribution feeders which have switched capacitor banks controlled by M-2501 series Autodaptive® Capacitor Controls. Use of VAr Bias allows the M-2001D to coordinate it’s operation with the M-2501 series Autodaptive Control devices on the distribution system in order to minimize losses, smooth the voltage profile and optimize VAr flow.–6–M-2001D Digital Tapchanger ControlOptional Bluetooth: The optional Bluetooth® (V2.0 +EDR Class 1 Type) provides wireless access to the M-2001D. With Bluetooth the user is able to configure the control, read status and metering values as well as change setpoints. This option can be field installed. There are two modes of operation for the Bluetooth:Mode 0 – The device is discoverable and connectable to any client station.Mode 1 – The device is non-discoverable but it is connectable to any client station who knows the control Bluetooth device address indicated under “Control BT Device” in the HMI.Mode 1 – Has been added to meet CIP requirement. (CIP-0007-4 System Security Management) (R2.3)Source Side PT Input: The Source Side PT Input feature provides for Reverse Power regulation with measured source side voltage. This mode consists of energizing a contact relay when reverse power is sensed which will switch the analog voltage input from the load side to the source side. Voltage regulation will then operate on the new measured source side voltage instead of the traditional source side voltage.SCAMP: (SCADA Controllable Auto/Manual Pushbutton) switch allows the Auto/Manual state on an adapter panel to be changed by a SCADA command.Monitoring/MeteringReal-Time Metering: The following single/three-phase measured and calculated values are available in real-time: • Primary Voltage • Meter Out Voltage • Source Voltage • Tap Position • Primary Source Voltage • Compensating Voltage • Drag Hands • Primary Current • Normalizing Voltage • Raise/Lower Timer • Primary Watts • Load Current • Intertap Timer • Primary VAr • Power Factor • Operation Counter • Primary VA • Frequency • Resettable Counter • Load Voltage • Circulating Current • Neutral CounterPresent Demand: The Present Demand feature captures the maximum values during the specified time interval.

Each tapchanger control can be assigned a Communications Address, Feeder Address or Substation Address ranging from 1 to 65519. Selected commands may be broadcast to all controls on the network. Figures 2, 3 and 4 illustrate typical network configurations. Addresses 1 to 247 can be assigned to MODBUS® and 1 to 65519 for DNP3.0.Application: Using a Windows™ based computer or wireless modem, the operator has real-time, remote access to all functions of the Digital Tapchanger Control. The control can act as the monitoring point for all voltage, current, and related power quantities, thereby simplifying operation while avoiding transducers and multiple Remote Terminal Unit (RTU) analog inputs. The protocols implement half-duplex, two-way communications. This allows all functions, which would otherwise require the presence of an operator at the control, to be performed remotely. Communication capabilities include: • Interrogation and modification of setpoints • Broadcast of commands, such as tapchange inhibit and voltage reduction (up to three steps) to networked controls • Recognition of alarm conditions, such as voltage extremes and excessive load • Selective control of raise and lower tapchange operations • Re-configuration of the control, such as a change to the demand integration time period or a selection of different alarm parameters • Unsolicited exception reporting multicast capability using UDP and TCP • DNP file transfer of Data Logging, Oscillography and Sequence of Events recordsUnit Identifier: A 2-row by 20-character alphanumeric sequence, set by the user, can be used for unit identification.Dymec Model No. 5843DTE=OnRepeat=OffTXRXST Multi-mode 62/125 Optical FiberConnect to computerStraight DB25Connection to ComputerRS-232 COM PortWindowsTM based computer RunningTapTalk® Communications SoftwareFigure 2 Fiber Optic Connection Loop (optional V-pin connection available)–12–M-2001D Digital Tapchanger ControlABModel No. 485 LP9TBB & B ElectronicsRS-232/RS-485120Connect to computerStraight DB9 Connectionto Computer RS-232COM PortWindowsTM based computer RunningTapTalk® Communications SoftwareFigure 3 RS-485 Network ConnectionHubNetworkCAT 5 Twisted Pair RJ-45orFiber Optic ThroughST ConnectorsWindowsTM based computer RunningTapTalk® Communications SoftwareFigure 4 Ethernet Network Connection–13–M-2001D Digital Tapchanger ControlTests and StandardsM-2001D Digital Tapchanger Control complies with the following type tests and standards:Voltage WithstandDielectric WithstandIEC® 60255-5 1,500 V ac for 1 minute applied to each independent circuit to earth 1,500 V ac for 1 minute applied between each independent circuitImpulse VoltageIEC 60255-5 5,000 V pk, +/- polarity applied to each independent circuit to earth 5,000 V pk, +/- polarity applied between each independent circuit 1.2 by 50 µs, 500 ohms impedance, three surges at 1 every 5 secondsIEC 60255-5 > 100 MegaohmsElectrical EnvironmentElectrostatic Discharge TestIEC 60255-22-2 Class 4 (±8 kV)—point contact dischargeIEC 60255-22-2 Class 4 (±15kV)–air dischargeFast Transient Disturbance TestIEC 60255-22-4 Class A (±4 kV, 2.5 kHz, 5 kHz)Surge Withstand CapabilityANSI/IEEE 2,500 V pk oscillatory applied to each independent circuit to earthC37.90.1- 2,500 V pk oscillatory applied between each independent circuit1989 5,000 V pk Fast Transient applied to each independent circuit to earth 5,000 V pk Fast Transient applied between each independent circuitIEEE 2,500 V oscillatory applied to each independent circuit to earthC37.90.1- 2,500 V oscillatory applied between each independent circuit2002 4,000 V pk Fast Transient burst applied to each independent circuit to earth 4,000 V pk Fast Transient burst applied between each independent circuit?

NOTE: Tap Position Sensors are available with either a positive "P" or negative "N" slope. Negative slope (clockwise rotation) causes a decrease in Tap Position. Positive slope (clockwise rotation) causes an increase in Tap Position.Table 1 M-2948 Model Application InformationThe tap position sensors are rotary shaft encoders with built-in microprocessors that provide stepped output signals in 9 or 10 degree increments. They have rotations of 297, 306, 315, 330, 340 and 350 degrees respectively for 32 taps and up to three neutral positions. The electrical output of these sensors is a 4-20 mA current loop that converts easily to a voltage signal at the input of the M-2025B(D) with the addition of a proper value shunt resistor. For a 4-20 MA Current Loop, 150 ohms is required on the input of the M-2025B(D).ConfigurationsMost LTC tapchangers have an output shaft on the tapchanger mechanism whose angular position is a mechanical analog of the tapchanger tap position. In many cases, the total range of tap positions is represented by less than one complete rotation of this position output shaft. The typical values of shaft movement on 32 tap mechanisms are 9° or 10° of mechanical rotation per tap position.Other angular rotation values are likely to be encountered. Contact Beckwith Electric for information on sensor availability for specific requirements.Application Notes • The M-2948 Tap Position Sensor directly mounts in place of the Incon Tap Sensor Model 1292. • The M-2948 Tap Position Sensor directly mechanically replaces the Selsyn-Type Position Sensor. • The M-2948-91N Tap Position Sensor is for use with a Qualitrol Position Indicator, Model 081-002-01 or equivalent.Incon Tap Position Monitor connected to an Incon 1250 Series Rotary Position SensorBoth types of devices provide a 4-20 mA dc current loop output. The current loop develops a voltage across a properly sized resistor on the input to the M-2025B(D). The resultant voltage signal is conditioned in the M-2025B(D) and routed to the M-2001 series Tapchanger Control where the voltage is converted to a corresponding tap position number.The tap position sensors are rotary shaft encoders with built-in microprocessors that provide stepped output signals in 9 or 10 degree increments. They have rotations of 288 and 320 degrees respectively for 32 taps and one neutral position. The electrical output of these sensors is a 4-20 mA current loop that converts easily to a voltage signal at the input of the M-2025B(D) with the addition of a proper value shunt resistor. For a 4-20 MA Current Loop, 150 ohms is required on the input of the M-2025B(D).–16–M-2001D Digital Tapchanger Control(-)B E C K W I T HE L E C T R I CCO. INC.M a d e i n U . S .
