GENERAL INFORMATION
INTRODUCTION
This manual contains installation, operation, and maintenance and repair instructions for Fincor Series 2230 MKII
Single-Phase Adjustable-Speed Regenerative DC Motor Controllers. A parts list, ratings and specifications, and
drawings are also included.
GENERAL DESCRIPTION
Series 2230 MKII Controllers statically convert AC line power to regulated DC for adjustable-speed armature
control of shunt-wound and permanent-magnet motors.
Applications include those requiring controllable bi-directional torque for overhauling loads, contactor-less
reversing, and position control.
Series 2230 MKII Controllers comply with applicable standards established by the National Electrical Code and
NEMA for motor and industrial control equipment. The controllers are Underwriters Laboratories Listed (File No.
E184521) UL/cUL.
MOTOR SELECTION
Series 2230 MKII Controllers control the operation of general purpose DC motors designed for use with solid-state
rectified power supplies. The motor may be shunt-wound, stabilized shunt-wound, or permanent magnet. For
maximum efficiency, the motor should be rated for operation from a NEMA Code K power supply.
DESCRIPTION OF OPERATION
Series 2230 MKII Regenerative Controllers, also known as four-quadrant controllers, not only control motor
speed and direction of rotation, but also the direction of motor torque.
Referring to Figure 1, when the drive (controller and motor) is operating in Quadrants I and III, motor rotation
and torque are in the same direction and the drive functions as a conventional non-regenerative drive. In
Quadrants II and IV, motor torque opposes the direction of motor rotation, which results in controlled braking.
The drive can switch rapidly from motoring to braking modes while simultaneously controlling the direction of
motor rotation. Under braking conditions, the controllers convert the mechanical energy of the motor and
connected load into electrical energy, which is returned (regenerated) to the AC power source.

SECTION II
INSTALLATION
Before starting the installation, read this section thoroughly. In addition, a thorough review of the Ratings and
Specifications (Section VI) is recommended. The following installation guidelines should be kept in mind when
installing the controller.
INSTALLATION GUIDELINES
1. CONTROLLER MOUNTING - The controller may be mounted either vertically or horizontally. However, never
mount the controller upside down, immediately beside or above heat generating equipment, or directly below water or
steam pipes.
The controller must be mounted in a location free of vibration.
Multiple controllers may be mounted side by side, as close to each other as the mounting feet will allow.
The minimum clearance at the top and bottom of the controller may be as narrow as the conduit fittings allow.
2. ATMOSPHERE - The atmosphere surrounding the controller must be free of combustible vapors, chemical fumes,
oil vapor, and electrically conductive or corrosive materials.
The air surrounding an enclosed controller must not exceed 40 degrees C (104 degrees F), and the air surrounding an
open-chassis controller must not exceed 55 degrees C (131 degrees F). Minimum air temperature is 0 degree C (32
degrees F) for enclosed and open-chassis controllers.
3. CONTROLLER CONSTRUCTION - Enclosed controllers are totally enclosed, non-ventilated, and comply with
NEMA Type 4 and 12 standards. There is an oil resistant synthetic rubber gasket between the cover and base. Those
models with integral operator controls include flexible boots to seal the switches, and a seal for the MOTOR SPEED
potentiometer.
Model 2235MKII and 2236MKII controllers are unenclosed open-chassis units with the printed wiring board mounted on
an aluminum bracket.
The small controller base is made of die-cast aluminum with a powdered epoxy finish, and the cover is made of a die-
cast aluminum alloy. The larger controller base is made of extruded aluminum and the cover is made of Noryl®, a
strong engineering plastic with outstanding mechanical, thermal, and electrical properties.
4. LINE SUPPLY - The controller should not be connected to a line supply capable of supplying more than 5,000
amperes short-circuit current. Short-circuit current can be limited by using an input supply transformer of 50 KVA or
less, or by using correctly sized current limiting fuses in the supply line ahead of the controller. Do not use a
transformer with less than the minimum transformer KVA listed in Table 8, page 29.
If rated line voltage is not available, a line transformer will be required. If the line supply comes directly from a
transformer, place a circuit breaker or disconnect switch between the transformer secondary and the controller. If power
is switched in the transformer primary, transients may be generated which can damage the controller. See Table 8 (page
29) for minimum transformer KVA.
Do not use power factor correction capacitors on the supply line to the controller.
A 20 Joule metal oxide varistor (MOV) is connected across the controller terminals. If higher energy transients are
present on the line supply, additional transient suppression will be required to limit transients to 150% of peak line
voltage.

BOOK 0960-B
4
When a 115 VAC line supply is used, connect the white (common) wire to Terminal L2 and connect the remaining
(hot) wire to Terminal L1.
5. ISOLATION TRANSFORMER - While not required, an isolation transformer can provide the following
advantages:
a. Reduce the risk of personal injury if high voltage drive circuits are accidentally touched.
b. Provide a barrier to externally generated AC supply transients. This can prevent controller damage from abnormal
line occurrences.
c. Reduce the potential for damaging current if the motor armature, motor field, or motor wiring becomes grounded.
6. GROUNDING - Connect the green or bare (ground) wire of the line supply to the ground screw located near the top
conduit entry hole in the controller base. Then ground the controller base by connecting the ground screw to earth
ground.
The motor frame and operator control stations must also be grounded.
Personal injury may occur if the controller, motor, and operator stations are not properly grounded.
7. WIRING PRACTICES - The power wiring must be sized to comply with the National Electrical Code, CSA, or
local codes. Refer to the controller data label for line and motor current ratings.
Do not use solid wire.
Signal wiring refers to wiring for potentiometers, tachometer generators, and transducers. Control wiring refers to
wiring for operator controls, e.g., switches and pushbuttons. Signal and control wiring may be run in a common
conduit, but not in the same conduit as the power wiring. In an enclosure, signal and control wiring must be kept
separated from power wiring and only cross at a 90 degree angle to reduce electrical noise.
If shielded wire (such as Alpha 2422 - two conductor, 2423 - three conductor, 2424 - four conductor) is used for the
signal and control wiring, connect the shields to chassis ground (ground screw on the controller base) and tape the
opposite ends of the shields. Twisted cable is also suitable for signal and control wiring.
The small base models provide two 3/4-14 NPT threaded holes for conduit entry, one each in the top and bottom of the
controller.
The large base models provide two 3/4 inch conduit entry for the power in and out wiring, and one 1/2 inch conduit
entry for signal wiring.

INSTALLING THE CONTROLLER
1. Remove the controller front cover (if used) by removing the four cover screws.
2. Check components in the controller for shipping damage. Report shipping damage to the carrier.
3. Check the controller and motor data labels to be sure the units are electrically compatible.
4. Be sure the controller has been calibrated correctly for the motor being used. The initial calibration is performed
by changing the position of a Jumper J4 on the controller control board to comply with Table 2. To change the
position of Jumper J4, pull the jumper from the control board and then push it onto the appropriate two pins on the
board. Select the position closest, but not less then, the motor nameplate armature current rating. The final calibration can be
fined tuned, if needed, by the current limit potentiometer. For the location of J4 and the current limit potentiometer, see
Figure 20 (page 35).

5. Check the positions of Jumpers J1, J2, and J3 on the control board. For the locations of J1, J2, and J3, see Figure 20,
page 35. For a 230 VAC line supply and a 180V armature motor, Jumper J1 must be in the 230V position, and Jumpers
J2 and J3 must be in the 180V position. For a 115 VAC line supply and a 90V armature motor, J1 must be in the
115V position, and J2 and J3 must be in the 90V position. To change the position of J1, J2, or J3 pull the jumper
from the control board and then push it onto the appropriate pins on the board.
NOTE: If Option 1001 (Armature Contactor), or 1775 (Signal Interface) is to be installed in the controller, do not offset
the five-position plug (supplied with the option) at Connector J1 on the control board. Do not confuse Connector J1 with
Jumper J1. Refer to the Instruction Sheet (ISP0703, ISP0653, respectively) supplied with the option for connection
instructions.
6. If the controller is to operate from a 50 Hz supply, set segment 6 of the DIP Switch (SW3) to the “OFF”
position on the controller control board. For the location of DIP Switch SW3, see Figure 20, page 35.
7. The controller may be surface mounted or panel mounted as shown in Figure 1, page 7. Mount the controller.
Mounting dimensions are shown in Figure 2, page 8.
8. Conduit entry is made by punching out the knockout at the top or bottom of the controller base. To prevent
component damage from knockout fragments, apply masking tape to the inside of the knockout before punching.
9. Connect the power wiring to Terminals L1, L2, A1, A2, F+ and F-. Be sure to observe Installation Guidelines 4 and
7 on pages 3 and 4. If half-wave shunt field voltage is desired, connect one of the motor shunt field leads to
Terminal L1 (see Table 12 on page 32).
Note: Low inductance motors require a full-wave field to prevent current instability.

BOOK 0960-B

10. If the controller contains any options that require external wiring, follow the wiring instructions in the instruction
sheet supplied with the option.
11. If remote operator control wiring and/or signal wiring is required, connect the controller as shown in the appropriate
connection diagram (Figures 3 through 18). Figures 3 through 9 show operator control connections, and Figures 10
through 18 show signal connections.
12. The controller can be programmed for various applications by throwing switches on dip switch SW3
