3.0 External Connections
Terminal Block Assignments
The external connections to the control are made to the two terminal blocks located on the
rear of the control, see Figure 3. See "Terminal Block Assignments" later in this section for
a description of each terminal assignment. For example, if external dry contacts are being
used to control the Voltage Reduction Step #1 function, connections for these contacts
may be made between TB1-4 and TB1-7 as shown in Figure 3. The dry contact inputs for
non-sequential input, voltage reduction must be "wetted" by connecting to terminal TB1-4.
See Table 1.
Typical Connections
Figure 3 illustrates typical connections for a regulator control. Motor Power and sensing
voltage can be obtained from a common source or from an independent source having a
nominal 120 Vac output. Normally, this is line-to-neutral voltage, although line-to-line voltage
can be used if recognition is made of any phase shift between the voltage and current signals
when using line drop compensation.
CAUTION:▲The current input to the M-6200A is rated at 0.48 A continuous, and
4.0 A for 1 second.
Load current must be reduced by an appropriate auxiliary transformer to 0.2 A "full scale"
before connecting to the regulator current inputs.
Grounding
WARNING:8The protective earth grounding terminal must be connected to
the installation earth ground anytime external connections have
been made to the unit.
Ground the control by connecting a 14 AWG, 300 V min., 105° C green insulated wire inserted
in an Amp 51864-8 or equivalent ring connector wire to the marked protective earth terminal
located adjacent to either side of TB1. Connect to the installation ground.
Unit Isolation
Sensing inputs should be equipped with test switches and shorting devices where necessary
to isolate the unit from external potential or current sources.
A switch or circuit breaker for the M-6200A's power shall be included in the building
installation, and shall be in close proximity to the control and within easy reach of the
operator, and shall be plainly marked as being the power disconnect device for the control.
Torque Requirements
Terminals TB1-1-16 & TB2-1-12: 7.5 in-lbs, minimum and 8.0 in-lbs, maximum.
Control Power Backup Input Connection
The Control Power Backup Input (Figure 4) is designed to sustain communication port
operation in the event of the loss of AC control power. In the event of a loss of AC input
power to the control, this feature permits uninterrupted operation of the control by supplying
+12 Vdc to the control. In addition, the control retains functionality with the exception of the
actual operation of the tapchanger mechanism.
When the AC input voltage drops below approximately 85 Vrms, the Control Power Backup
Input will activate and all automatic tapchange operations will then be suspended. If Motor
Power is available, manual tapchanges may be initiated.
When the control is being powered only by the backup DC input the Auto/Manual switch
status and the Local/Remote switch status are functional. When a control is being supplied
by both AC and DC via the backup power input and the backup DC input is lost the unit will
report it via DNP.

B‑2355 Cooper
–5–
When the control is being powered from the Control Power Backup Input, it will continue to
read any input voltage present.
The control retains full functionality, and if the control's Motor Power remains energized
then Raise and Lower commands from SCADA are possible. Fiber-Optic port operation is
maintained. All communication ports, data-logging, status monitoring, configuration, and
setpoint capability are also maintained.
Beckwith Electric offers two Control Power Backup supplies for use with the M-6200A.
The M-2026 AC-DC Control Power Backup Supply is a fused, surge protected and reverse
polarity protected AC-DC Control Power Supply that accepts an AC or DC input (21 to 32,
42 to 60 and 105 to 145 V) and outputs regulated +12 Vdc at up to 1.5 Amp.
The M-2027 Control Power Backup Supply - AC Only is a fused and surge protected Control
Power Backup Supply that will accept an AC input range of 105 to 140 Vac, 50/60 Hz and
output +12 Vdc to 1 A.
Both the M-2026 and M-2027 are housed in non-weathertight enclosures and are equipped
with screw terminal blocks for both input and output connections.
Backup Power Requirements
The Control Power Backup Input that does not utilize the M-2026 or M-2027 should only be
used with the optional (B-0920) 3-Wire Harness. The harness (Figure 5), includes a 3 Amp
fast-blow fuse, and connects to TB2-11 (–) and TB2-12 (+) of the control.
CAUTION:▲Use of Non-Beckwith Electric converters to provide +12 V to the
Control Power Backup Input may compromise system integrity due
to a lack of adequate protection of the power converter. For reliability
of the M-6200A, the power converter must meet the following
requirements:
Temperature: Operational from -40° C to + 85° C.

TERMINAL BLOCK ASSIGNMENTS (TB1)
TB1‑1 Non-Sequential Operation/Auto Tapchange Inhibit (or Aux 2)
Non-Sequential Operation
CAUTION:▲Voltage applied through dry contacts to actuate non-sequential input
and voltage reduction inputs must be nominal +12 Vdc obtained from
TB1-4 of the M-6200A Regulator Control. The use of 120 Vac will
result in damage to the control.
The operation of the control can be interrupted during tapchanger operation by applying the
"wetting" voltage of TB1-4 to TB1-1 (timer reset for non-sequential operation input) on the
control through an external contact. This causes the output to de-energize and reinitialize
the time delay circuit when the reset signal is removed. This function can be used to cause
the Regulator, if so equipped, to wait for the unit to time out between tapchanges.
Non-sequential operation is invoked by momentarily connecting this input to the nominal
+12 Vdc wetting source (TB1-4) through an external Form "a" dry contact. When this function
is enabled, the tapchanger control times out with the Time Delay setting between every
tapchange.
Auto Tapchange Inhibit
Auto tapchange inhibit is invoked by closing and maintaining a Form "a" dry contact connected
to this input and to the nominal +12 Vdc wetting source (TB1-4). As long as this contact is
closed, the tapchanger will not time out, thereby prohibiting raise and lower commands.
Auxiliary Input (Aux 2)
To monitor the Battery Alarm Status, the optional Battery Pack sense line must be connected
to TB1-1 and the Non-Sequential input must be configured as "Aux 2".
TB1‑2 Voltage Reduction Step #2 (or Aux)
TB1‑7 Voltage Reduction Step #1 (or Aux 1)
CAUTION:▲Voltage applied through dry contacts to actuate non-sequential input
and voltage reduction inputs must be nominal +12 Vdc obtained from
TB1-4 of the M-6200A Regulator Control. The use of 120 Vac will
result in damage to the control.
On the M-6200A Digital Regulator Control, TB1-2 and TB1-7 are used together to provide
up to three levels of voltage reduction. The external connections to achieve these steps
are shown in this Table 1. Voltage reduction amounts are set within the M-6200A Digital
Regulator Control software. If these voltage reduction steps are instituted by communications,
the contacts are not being used simultaneously.
NOTE:QEnabling both voltage reduction Step #1 and Step #2 inputs simultaneously
will result in the level of voltage reduction as specified on the voltage
reduction Step #3 screen of the control.
These digital inputs are typically enabled by connecting it to the nominal +12 Vdc wetting
source (TB1-4), through an external Form "a" dry contact. The amount of voltage reduction
implemented is determined by the setting.

TB1‑3 No Connection or Source Voltage
TB1‑4 +12 Vdc Wetting Voltage
This is the output of an unregulated dc power supply internal to the control. It is referenced to
neutral and can supply up to 100 mA. It is used for powering the digital inputs of the control
through external dry contacts. Depending on the voltage supplied to TB1-10 and loading,
its output can vary from +10 to +18 Vdc. The output is current limited with a 1 ohm resister.
TB1‑5 Regulator Raise Output
This switched output connects the tapchanger raise winding to the source of motor power.
When the control calls for a raise, it is capable of switching up to 6 A at 120/240 Vac.
TB1‑6 Regulator Lower Output
This switched output connects the tapchanger lower winding to the source of motor power.
When the control calls for a lower, it is capable of switching up to 6 A at 120/240 Vac.
TB1‑8 Neutral
This is the return for the nominal +12 Vdc “wetting” voltage (TB1-4) and the voltage input
(TB1-10).
TB1‑9 Motor Power Input
The source for powering the tapchanger motor is connected here. It may have a maximum
voltage of 240 Vac.
TB1‑10 Load Voltage Input
This input accepts nominal 120 Vac, 60 Hz (or 50, Hz as ordered) to operate the control's
power supply and voltage sensing input. The acceptable voltage range for proper control
operation is from 90–140 Vac.
Power consumption is less than 8 VA. The input voltage is referenced to line neutral (TB1-8).
TB1‑11, TB1‑16 Neutral Tap Position Inputs
This digital input registers neutral position switch closures on regulators. The pins are
isolated from neutral to permit connection of the input based on regulator configuration.
TB1‑12 Drag Hands Reset
The drag hand reset output (TB1-12) connection is commonly used to reset the drag hand
on the regulator. When the Drag hand switch on the M-6200A is activated, this will cause
the unit to output 120 V to TB1-12. This voltage can be used to energize the drag hand
circuitry on the regulator.
TB1‑13 Operations Counter Input
This digital input registers the counter contact closure. The operations counter will increment
when TB1-13 is grounded by way of the regulator dry operation count switch. This contact is
needed for using the intertap time delay. Once a valid counter input is detected, the intertap
time delay will begin counting down.

The line current input range is 0–640 mA (480 mA continuous) with 200 mA representing
the 1.0 per-unit value. The measured current value is used for line drop compensation and
metering calculation.
TB1‑15 Load Current (-)
This is the non-polarity input to the load current measuring transformer. The companion
polarity input is TB1-14. The line current transformer input is isolated from other pins.

Regulator Controls Replacement
The Beckwith Electric M-6200A Digital Regulator control directly replaces Cooper CL-2,
CL-2A, CL-4A, CL-4B, CL-4C, CL-5 and CL-6 Regulator Controls.
The M-6200A may be purchased with the factory installed hardware kits:
• B-2355-C1 CL-2 through CL-5
• B-2355-C2 CL-6
• B-2355-C3 CL-2 through CL-5
• B-2355-C4 CL-6
The contents of the hardware kits provide the means to install the M-6200A in the existing
Cooper Regulator Control cabinet. The B-2355-C1, B-2355-C2, B-2355-C3, B-2355-C4
are available separately from the factory for field installation.
The difference between the B-2355-C1/B-2355-C3 and B-2355-C2/B-2355-C4 hardware
kits is the B-2355-C1/B-2355-C3 contains the harnesses for CL-2 through CL-5 control
replacement and the B-2355-C2/B-2355-C4 contain the harnesses for CL-6 control
replacement. The remaining kit contents are the same.
Application
Typical Connections
In general, the tapchanger motor must be operated from a different transformer than the
VT used to measure regulated voltage. If this is not done, hunting at the upper band edge
may result. As soon as the motor starts, and before it is sealed in, the motor current can
drop the voltage within the band and reset the control. Some motor seal-in schemes are
fast enough to prevent this, but others are not.
Pulsed output can be used on the M-6200A (see Instruction Book, Section 4.2 System
Setup, Output Pulse).
External Connections
Power and voltage sensing are obtained either from a common source or from independent
sources having a nominal 120 Vac output. Normally, this is line-to-neutral voltage, although
line-to-line voltage can also be used if recognition is made of any phase shift between the
voltage and current signals when using line drop compensation.
The external connections for the M-6200A are made to terminal blocks TB1 and TB2 on the
rear of the control panel. The wiring harness and external connections for the M-6200A are
shown in Figure 8, Figure 9, Figure 10, and Figure 11.
Lightning Protection
CAUTION:▲For proper protection against system surges, chassis ground must be
connected to earth ground.
It has been determined that transient voltages in excess of 1500 Vac RMS can exist on the
"ground" lead normally tied to TB1-8. In the regulator controls, these voltages are suppressed
by varistors which still permit the unit to pass a 1500 Vac hi-pot test for one minute, with a
leakage of approximately 15 mA, all terminals to ground.
Multiple VT grounds far apart must be avoided, since a varying difference in ground voltage
could add or subtract from the effective voltage, and cause variation in the tapchanger
control’s bandcenter voltage setpoint.
Non-Sequential Operation/ Counter Input
Not normally used with Cooper Regulators.

Multi-Step Voltage Reduction
CAUTION:▲Voltage applied through dry contacts to actuate Voltage Reduction
Steps 1, 2, and 3 must be +12 Vdc obtained from terminal TB1-4 of
the M-6200A Regulator Control.
The M-6200A uses terminals TB1-2 and TB1-7 together to provide up to three levels of
voltage reduction. The external connections to achieve these steps are shown in Table 1
and Figure 3. Voltage reduction amounts are set in the M-6200A Regulator Control software.
Removal of the Cooper Control
WARNING:8In no case should the line current circuit be interrupted with
the regulator or transformer energized. Do not remove auxiliary
current transformers without shorting the current inputs. Death
or severe electrical shock can occur.
1. Verify that the regulator control wiring is in a safe condition that will allow removal
of the Cooper Regulator Control from the control cabinet.
• The control wiring is de-energized and isolated from any potential safety
hazards.
• All local Safety Tagging rules have been applied as necessary.
2. Open the cabinet door of Cooper control.
3. Loosen the thumb screws on the control panel (Figure 6), and swing the panel
outward.
WARNING:8In no case should the line current circuit be interrupted with
the regulator or transformer energized. Do not remove auxiliary
current transformers without shorting the current inputs. Death
or severe electrical shock can occur.
4. De-energize the control by opening the VT disconnect switch and placing the
CT switch in the shorting position. Ensure that the CT in the regulator has been
properly shorted.
5. Loosen the screws on the spreader bar terminal block at the bottom of the cabinet,
then pull down on the spreader bar to disconnect it.
NOTE:QThe two hinge pins must be saved from the original control.
6. Remove and save the two hinge pins, then lift the panel off of the hinges and
remove it from the cabinet.
