About This Manual

This manual contains the basic information needed to install and operate the

Bodine Model 3984 Isolated Interface Module. It is organized in a systematic,

step-by-step fashion so that it may be installed in the shortest possible time. It

does not profess to cover all details or variations in equipment, nor to provide

for every possible contingency associated with installation, operation, or

maintenance. No warranty of ﬁtness for purpose is expressed or implied.

Should further information be desired or should particular problems arise

which are not covered sufﬁciently for the user’s purpose, the matter should

be referred to the Bodine Electric Company.

The issuance of this manual does not confer to the recipient any license to

manufacture under any patents owned or controlled by the Bodine Electric

Company.

Safety Standards

Bodine products are designed and manufactured to comply to applicable

safety standards and in particular to those issued by ANSI (American

National Standards Institute), NEMA (National Electrical Manufacturers

Association), U.L. (Underwriters Laboratories, Inc.), and CSA (Canadian

Standards Association).

Bodine equipment “recognized by U.L., Inc.” are either labeled

with the UR or cURus marks. In addition, products that are CSA

certiﬁed are identiﬁed by the CSA mark. If you need speciﬁc

information regarding the third-party approval status of Bodine

products, contact the nearest Bodine representative, or the

home ofﬁce.

DESCRIPTION AND FEATURES

Most Bodine motor controls have ﬂoating signal commons (i.e. the signal

common is not at ground potential). Input signals from transducers,

microprocessor controls, programmable logic controllers, and other

www.bodine-electric.com 5

electronic control devices may produce grounded signals or signals which

are at a different potential from those used in Bodine motor controls. The

Model 3984 Isolated Interface Module is designed to provide an interface

which optically isolates the motor control signals from external electronic

control signals, while still providing full use of Bodine control features.

The Model 3984 is a scalable voltage following device that accepts a wide

range of current and voltage analog speed input signals and delivers an

isolated output speed signal of 0 to +10 VDC @ 10mA. A built-in sensor circuit

monitors the polarity of the analog voltage speed input and changes the

motor’s direction of rotation when the signal goes from positive to negative.

Adjustable minimum and maximum potentiometers allow the output speed

signal to be scaled or offset in order to achieve a desired response based on

a given value of input signal.

Isolated motor disable and direction of rotation signals are also provided

as well as an isolated tachometer output which can be used to monitor the

speed of Bodine brushless DC motors. Isolated power supply connections are

provided on both the input and output sides of the Model 3984 for convenience.

The power supply delivers ±12 VDC @ 10mA at the +ISO/-ISO terminals and

+12VDC @ 10mA at the V + terminal.

The model 3984 can be used in a variety of conﬁgurations to control several

slave motor/control circuits from a single master. Conﬁguration examples are

described in the Application Information Section of this manual.

IMPORTANT SAFETY PRECAUTIONS

The following safety precautions must be observed during all phases of

installation, operation, service, and repair of this module. Failure to comply

with these precautions or with speciﬁc warnings elsewhere in this manual

violates safety standards of design, manufacture and intended use of the

product. Bodine Electric Company assumes no liability for the customer’s

failure to comply with safety requirements and practices.

The use of electric motors and gearmotors, like that of all utilization of

concentrated power, is potentially hazardous. The degree of hazard can be

greatly reduced by proper design, selection, installation, and use, but all

hazards cannot be completely eliminated. The reduction of hazards is a joint

responsibility between the user, the manufacturer of the driven or driving

equipment and the manufacturer of the control or motor and interface circuitry.

The user should refer to Publication No. ANSI C5.1/NEMA MG 2, Safety

Standard for Construction and Guide for Selection, Installation and Use of

Electric Motors and Generators.

Available from:

National Electrical Manufacturers Association

www.nema.org

Warnings highlight procedures which present potential danger to people.

Cautions highlight possible danger to equipment. Both are used through-out

this manual and must always be followed.

WARNING

The chance of explosions, ﬁres or electric shocks can be reduced

with thermal and over-current protection, proper grounding, enclosure

selection, and good maintenance. The following safety considerations

are not intended to be all-inclusive. Speciﬁc references throughout the

manual should also be consulted.

Inspection

Check the items you received against your purchase order. Carefully examine

the interface module for shipping damage. Report parts errors to Bodine.

Shipping damage claims should be made to the freight carrier.

Before installing this interface module, review the application to conﬁrm

that the proper motor and control have been selected. This should be done

after reading the manual provided with the motor and all applicable safety

standards. If in doubt, contact your Bodine representative, or the home ofﬁce

www.bodine-electric.com 7

if there is no representative in your area. Although Bodine Electric Company

assists its customers in selecting motors and controls for speciﬁc applications,

determinationofﬁtnessforpurposeoruseissolelythecustomer’sresponsibility.

Grounding

Both electronic controls and motors must be securely mounted and adequately

grounded. Failure to ground properly may cause serious injury to personnel.

Fusing

The AC input to the isolated interface module should be fuse protected. The

fuse must conform to the value and rating listed on page 15.

Environment

Open circuit boards in ventilated enclosures may emit ﬂame during failure.

Bodine does not offer an explosion-proof line of motion control accessories for

hazardous locations (e.g., environments of ﬂammable or explosive gas, vapor,

or dust). Bodine recommends using only approved explosion-proof products

in hazardous locations. The National Electric Code (NEC) allows exceptions,

but NEC and NEMA safety standards should be studied thoroughly before

exercising this option.

Moisture increases the electrical shock hazard of electrical insulation.

Therefore, this module and other open-type or unsealed accessories or

controls not speciﬁcally designed for such use, should be protected from

contact with liquids or moisture.

Ventilated Products

Open, ventilated products are suitable for clean, dry locations where cooling

air is not restricted. Do not insert anything into a product’s ventilation

openings.

Servicing

Emergency ﬁeld repairs must be made only by authorized Bodine service

representatives. Repairs made by persons not authorized by the Bodine

Electric Company will void the warranty. Field repairs must be limited to

replacing the entire printed circuit board assembly. Because of the danger

of introducing safety hazards, do not install substitute parts or perform any

unauthorized modiﬁcations to electronic PC boards or components. To ensure

continued compliance with the design speciﬁcations and safety standards,

the interface circuit module should be returned to Bodine Electric Company

or an Authorized Service Center for servicing.

APPLICATION INFORMATION

The Bodine Model 3984 Isolated Interface Module is a versatile device

which can be used with a single motor and control or combined with other

3984 modules, motors, and controls to satisfy a variety of motion control

applications. The following information is provided as reference material; it

does not include every possible conﬁguration. If you have any doubts about

using the Model 3984 for a speciﬁc application, contact your local Bodine

representative or the home ofﬁce.

WARNING

To avoid injury because of unsuspected mechanical motion, always

disconnect the power supply to the motor control before performing any

service procedures on the motor, control, interface circuitry or driven

equipment.

CAUTION

This section is not a substitute for installation and operating instructions.

Refer to those sections for details on mounting, wiring, and operation.

Typical Control Signal Isolation

In simple applications involving a single motor and control, the Model 3984

accepts signals from a variety of motion control sources and generates

isolated output signals which are compatible with Bodine motor control

inputs. Figure 2 illustrates typical inputs and outputs for a Model 3984 when it’s

used to isolate ABL-3910 or 3911 and UPM-3318C control inputs. Refer to the

Installation Instruction Section of this manual for speciﬁc wiring variations,

DIP switch settings, and other pertinent information.

www.bodine-electric.com 9

Bi-Directional Master Speed Control

The input side of the Model 3984 provides connections to an internal ± 12 VDC

power supply. If a 10 KQ potentiometer is connected across the power supply

and the wiper is connected to the VIN1 terminal of the Model 3984, as shown

in Figure 3, a voltage divider circuit is formed. When the wiper is in the center

position, zero volts is applied to VIN1, so the motor speed is zero RPM.

When the wiper is turned in one direction, a positive voltage is applied to VIN1

causing the motor to turn in a clockwise direction. When the potentiometer is

turned in the other direction, a negative voltage is applied to VIN1 causing the

motor to turn in the counterclockwise direction. The motor speed is always

directly proportional to the absolute value of the voltage applied to VIN1.

Master/Slave Signal Generator

Several Model 3984 modules may be conﬁgured in a master/slave arrangement

as shown in Figure 4. The speed outputs of each slave module can be scaled

or offset to achieve different results for each slave motor. Each slave module

can control a different type of motor/control system.

The output of the master module can drive up to 10 slave modules. Each

slave module will follow the output of the master, but will vary proportionally

depending on the scaling or offset factor. For more information on adjusting

the speed control, refer to “Internal Adjustments/Calibration” in the Operating

Instruction Section of this manual.
