MOTOR SELECTION
Series 2330MKII 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.

BOOK 0958-B
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 - The 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 controller enclosure is totally enclosed, non-ventilated, and complies 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.
4. LINE SUPPLY - The controller should not be connected to a line supply capable of supplying more than 100,000
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 31.
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
31) 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.
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.
3
BOOK 0958-B
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.
Two 3/4-14 NPT threaded holes are provided for conduit entry, one each in the top and bottom of the controller.

BOOK 0958-B
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. 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. For
the location of J4, see Figure 20 (page 37).

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 37. 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, Unidirectional), 1004 (Armature Contactor, Reversing), 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,
ISP0666, ISP0653, respectively) supplied with the option for connection instructions.
6. 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.
7. 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.
8. 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 F/2 (see Table 12 on page 33).
NOTE: Low inductance motors require a full-wave field to prevent current instability.
5
BOOK 0958-B
9. If the controller contains any options that require external wiring, follow the wiring instructions in the instruction
sheet supplied with the option.
10. 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 11 show operator control connections, and Figures 12
through 18 show signal connections.
11. The controller can be programmed for various applications by throwing switches on dip switch SW3

9. Check motor rotation, as follows:
a. If a MOTOR SPEED potentiometer is used, turn it fully counterclockwise. If an external signal is used for the
speed reference, set it at minimum.
b. If a RUN-STOP-JOG switch is used, place it in RUN position. Otherwise, initiate a Run command.
c. Turn the MOTOR SPEED potentiometer clockwise or increase the speed reference signal, as applicable. To stop
the motor, place the switch in STOP position or initiate a Stop command, as applicable.
If the motor rotates in the wrong direction, turn-off the AC supply to the controller, and then interchange the motor
armature leads at the motor connection box or at the controller terminal board.
10. Refer to Section III, “Operation” for operating instructions.

BOOK 0958-B
SECTION III
OPERATION
POWER ON/OFF
To energize the drive, turn-on the AC supply voltage to the controller. When this occurs, the motor shunt field
energizes with rated field voltage, and potentially hazardous voltage is present at the motor armature terminals. These
voltages can cause electric shock resulting in personal injury or loss of life.
If the AC supply is interrupted, and the controller is not set up for line starting, the motor will not restart when the
AC supply is restored until the controller is reset by initiating a Stop command and then a Start command. If the
controller is set up for line starting, and the AC supply is interrupted, the motor will restart when the AC supply is
restored, provided the external AC line contactor is pulled in.
RUN
If a RUN-STOP-JOG switch is used, place the switch in RUN position. Otherwise, initiate a Run command. A Run
command will accelerate the motor to the setting of the MOTOR SPEED potentiometer or external speed reference
signal, as applicable. The rate of acceleration is preset by the ACCEL potentiometer on the controller control board.
STOP
If a RUN-STOP-JOG switch is used, place the switch in STOP position. Otherwise, initiate a Stop command. A Stop
command will stop the motor at a rate proportional to the stopping rate of the motor load.
If the controller has dynamic braking, the motor stopping time will be reduced. Dynamic braking provides exponential
rate braking of the motor armature, which occurs when the circuit is opened between the controller and the motor
armature, and one or more resistors connect across the motor armature.
The dynamic braking resistors provide initial braking torque and stops per minute as shown in Table 5.

HIGH INERTIA LOADS MAY EXTEND BRAKING TIME AND CAUSE THE WATTAGE
RATING OF THE DYNAMIC BRAKING RESISTORS TO BE EXCEEDED.
An antiplug feature is included with optional Armature Contactor Reversing With Dynamic Braking (Option 1004).
This feature prevents restarting the motor before the motor has braked to a stop.
SPEED CONTROL
Motor speed is directly proportional to the setting of the MOTOR SPEED potentiometer or the magnitude of an
external speed reference signal, as applicable. This potentiometer or the speed reference signal may be adjusted while
the motor is running or may be preset before the motor is started.
The rates of acceleration and deceleration are preset by the ACCEL and DECEL potentiometers, respectively,
located on the controller control board.
Maximum speed and minimum speed are preset by the MAX SPD and MIN SPD potentiometers, respectively,
located on the control board.
TORQUE CONTROL
Motor torque is directly proportional to the setting of the CURRENT LIMIT potentiometer or the magnitude of an
external torque reference signal, as selected by dip switch SW3, position 3. This potentiometer or the current reference
signal may be adjusted while the motor is running or may be preset before the motor is started. Note that if the process
demands less torque then the torque reference is commanding, motor speed will continue to increase up to maximum
speed.
JOG
If a RUN-STOP-JOG switch is used, place the switch in JOG position. Otherwise initiate a Jog command. Jog is
momentary, causing motor rotation only while the switch is held in JOG position or while a Jog command is active.
Release the switch to stop the motor.
Normally, jog speed is directly proportional to the setting of the MOTOR SPEED potentiometer. If a separate JOG
SPEED potentiometer is used, jog speed will be directly proportional to the setting of the JOG SPEED potentiometer.
20
BOOK 0958-B
REVERSE
To reverse motor rotation on controllers with reversing capabilities, initiate a Stop function and then initiate a
reversing command. The motor will then accelerate to the setting of the MOTOR SPEED potentiometer or external
speed reference signal, as applicable. Forward and reverse speed ranges are identical.
If a FWD-REV switch is used, it must have a center position interlock, which requires a momentary relaxation of
pressure before the opposite position can be engaged. The center position causes a Stop command and allows time for
the motor to stop before a Reverse command is initiated. If a Reverse command is initiated while the motor is rotating,
motor and controller damage may occur.
If Option 1004 (Armature Contactor Reversing With Dynamic Braking) is installed, an antiplug feature prevents
reversing the motor before the motor has stopped.
LOAD MONITOR
UL approved as a motor protection device. The threshold for inverse timed overload will not exceed 120% of
rated current and will shut down the drive (drop out K0) in about 60 seconds at 150% load current. The drive
may be reset by cycling the enable line, or cycling input line power. Note that the timing capacitor is not reset by
this, and that if the drive is immediately restarted into an overload, it will not take the full time to trip.
CURRENT LOOP TRANSDUCERS
Several onboard features allow easy interfacing to 4-20mA type transducers as well as other current ranges with
appropriate external burden resistors. When SW3 position 2 is closed, an internal 249Ω resistor converts 4-20mA to
a 1-5V input, and SW3 position 4 in the closed position converts the Min Speed Potentiometer to an Input Offset
Potentiometer that allows precise nulling of the zero speed point.
INOPERATIVE MOTOR
If the motor stops and/or won’t start, turn-off the AC supply to the controller, remove the controller cover (if used),
and check the AC line fuse on the controller control board. For the location of the fuse, see Figure 23, page 37. If the
fuse is blown, refer to the Troubleshooting Table (Table 6).

SECTION IV
MAINTENANCE AND REPAIR
GENERAL
1. Keep the controller dry and free of dust, dirt, and debris. No parts require periodic replacement.
2. Periodically turn-off the AC line supply to the controller and check all wire terminations to be sure they are tight.
3. Visually check components for damage due to overheating or breakage. All damaged and/or faulty components must
be replaced for satisfactory operation.
4. Maintain the motor according to maintenance instructions supplied by the motor manufacturer.
ADJUSTMENT INSTRUCTIONS
ACCELERATION
1. Set the MOTOR SPEED potentiometer at 100% or the external speed reference signal at maximum, as applicable.
2. Initiate a Run command and observe the time required for the motor to reach maximum speed.
3. Adjust the ACCEL potentiometer for the desired rate. Full counter clockwise rotation is the fastest acceleration
(0.1 second), and full clockwise rotation is the slowest acceleration (30 seconds).
DECELERATION
1. With the motor running at maximum speed, quickly reset the MOTOR SPEED potentiometer to zero, or quickly
decrease the speed reference signal to minimum, as applicable, and observe the time required for the motor to reach
minimum speed.
2. Adjust the DECEL potentiometer for the desired rate. Full counter clockwise rotation is the fastest deceleration (0.1
second), and full clockwise rotation is the slowest deceleration (30 seconds).
IR COMPENSATION
IR compensation is used only for armature feedback. The IR/COMP potentiometer is factory set at zero (full
counterclockwise rotation) for satisfactory operation with most motors. If improved speed regulation is desired,
readjust IR compensation as follows:
1. If the motor is shunt-wound, run it at rated base speed. If the motor is a permanent-magnet type, run it at about 1/3
speed.
2. Turn the IR/COMP potentiometer clockwise slowly until motor speed becomes unstable.
Then turn the potentiometer counterclockwise until motor speed stabilizes.
MAXIMUM SPEED
The MAX SPD potentiometer is factory set to provide 90 VDC armature voltage with a 115 VAC line, or 180 VDC
armature voltage with a 230 VAC line.
To readjust maximum speed, run the motor at maximum speed and adjust the MAX SPD potentiometer for the desired
maximum speed.
NOTE: If the MAX SPD potentiometer is turned too far counterclockwise, speed instability may occur.
23
BOOK 0958-B
MINIMUM SPEED
1. Turn the MIN SPD potentiometer fully counterclockwise (0%) for zero speed.
2. Set the MOTOR SPEED potentiometer at 0% or the external speed reference signal at minimum, as applicable.
3. Initiate a Run command and adjust the MIN SPD potentiometer for the desired minimum speed (adjustable
from 0 to 40% of motor base speed).
CURRENT LIMIT
1. Turn the CUR LMT potentiometer fully clockwise (100%) to limit motor armature current at 150% of rated.
2. Turn the CUR LMT potentiometer counterclockwise to reduce maximum motor armature current.
NOTE:An external 5K ohm Current (Torque) Limit potentiometer can be used as shown in Figure 14 on page 14. Dip
switch SW3 position 3 must be in the OFF position if an external Current (Torque) Limit potentiometer is desired.
3. The GREEN power on LED indicator will change to RED whenever the controller is limiting (or regulating) current
to the motor.
TACHOMETER FEEDBACK SETUP
1. Before connecting or configuring tachometer feedback, follow the instructions to install and perform initial
startup, then run drive with maximum input speed reference and adjust the MAX SPEED potentiometer (R8b) for the
desired maximum motor speed. Note that for best performance, this should be within +/-20% of the motor nameplate
maximum speed or stability problems may occur.
2. Connect the tachometer wires to TB2:7 and 5 (polarity insensitive) and move the one piece jumper on J6, J7 and
J8 from the ARM position to the TACH position. (Figure 20 on page 37)
3. Select the tachometer voltage scaling at max speed by dip switch SW3:1 as follows:
TACH VOLTAGE
SW3:1
8Vdc - 30Vdc
ON
31Vdc - 175 Vdc
OFF
4. Adjust the IR/TACH MAX SPEED potentiometer fully clockwise, this will provide minimum speed with tach
feedback.
5. Run the motor with maximum speed reference and start adjusting the IR/TACH MAX SPEED potentiometer
counterclockwise until motor speed increases to the desired maximum speed with tach feedback. Note that if the
tachometer signal is lost, the drive will automatically revert back to armature feedback.

SPECIFICATIONS
1. AC LINE PROTECTION - A 100,000 ampere interrupting capacity AC line fuse provides instantaneous protection
from peak loads and fault currents. This line fuse is located inside the controller.
2. AUXILIARY CONTACT - A normally-open Form A relay contact, rated .5 ampere @115 VAC and 2A at 30 VDC,
is available for external use. The relay energizes when a Run command is initiated, and de-energizes when a Normal
Stop command is initiated, the overload monitor trips, or the anti-restart circuit is activated.
3. FIELD SUPPLY - A half-wave or full-wave shunt field supply is available as shown in Table 12;

BOOK 0958-B
4. MOTOR CONTACTOR - Controller model numbers with an ‘A’ or ‘B’ suffix, e.g., 2331A, 2331AP0, have a DC
magnetic armature contactor, which disconnects both motor armature leads from the controller. An antiplug circuit
ensures that the contactor does not make or break DC.
5. POWER CONVERSION - The DC power bridge consists of four SCR’s, one freewheeling diode. Each device is
rated at least 600 PIV. The controller base forms an integral heat sink, with the power devices electrically isolated from
the base.
6. SELECTABLE CAPABILITIES - Switches allow the user to select various modes of operation, as follows:
a. LINE STARTING - By placing SW3:5 in the OFF position, the anti-restart feature will be disabled, and the
controller may be started and stopped with an external AC line contactor. However, a wire jumper must be connected
between TB2-8 and TB2-9. If full speed operation is desired, connect another wire jumper between TB2-2 and TB2-3.
b. TACHOMETER FEEDBACK - To use tachometer feedback with armature feedback backup, connect the
tachometer generator signal to TB2-7 and TB2-5, (polarity insensitive) and select the tachometer generator voltage at
maximum speed by using SW3:1 as follows:
TABLE 13. TACHOMETER FEEDBACK VOLTAGE SELECTION
TACH VOLTAGE
SW3:1
8Vdc - 30Vdc
ON
31Vdc - 175 Vdc
OFF
c. TORQUE REGULATOR - The controller will function as a torque regulator when SW3:3 is OFF. This allows an
external potentiometer to set maximum motor torque (0 - 150% of rated).
7. VOLTAGE TRANSIENT PROTECTION - A metal oxide suppressor (varistor) across the AC line is combined
with RC snubbers across the power bridge to limit potentially damaging high voltage spikes from the AC power source.
