Page 4: General Information
GENERAL INFORMATION Thank you for selecting the Bodine Model 3984 Isolated Interface Module. It will provide the same excellent performance and reliability that have been a Bodine tradition since 1905. Bodine Electric Company takes price in the quality of its products and in satisfying its customers. Every effort has been made to provide you with a product free of defects in design, workmanship, and materials. -
Page 5: Specifications
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. -
Page 6: Important Safety Precautions
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... - Page 7 Although Bodine Electric Company assists its customers in selecting motors and controls for specific applications, determination of fitness for purpose or use is solely the customer’s responsibility. Grounding Both electronic controls and motors must be securely mounted and adequately grounded.

Page 8: Application Information
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. -
Page 9: Bi-Directional Master Speed Control
Figure 2– Typical Isolated Inputs for Bodine Controls 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. -
Page 10: Master/Slave Signal Generator
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. -
Page 11: Installation Instructions
No. 8 machine screws. Electrical Connections All connections to the Model 3984 are made at screw terminal blocks TB1, TB2, and TB3. See Figure 5. Read the following instructions and all of the applicable safety recommendations, before making any electrical connections. -
Page 12: Controlling Speed With An Analog Input Voltage
* DS1 lever 4 can be either ON or OFF depending on the direction control requirements See Page 13 – Automatic Direction Mode. Controlling Speed With an Analog Input Current: The Model 3984 will also accept current speed inputs. Current speed control signals are applied to VIN1 on TB2. -

VINI or VIN2 on Terminal block TB2. This automatic circuit is enabled by switching DIP Switch DS1, lever 4 ON. When used with Bodine ABL-3910/3911 controls as shown in Figure 2, the motor will rotate in a CW direction when VIN>0;... -
Page 14: Tachometer Output
AC Power Connections AC Power should always be the last connection made during installation and the first item disconnected before servicing. The Model 3984 may be connected to either a 115 VAC, 50/60 Hz or a 230 VAC, 50/60 Hz source. -
Page 15: Fuse Installation
Fuse Installation: It is recommended that the Model 3984 be protected with an external fuse. The amperage rating of the fuse depends on the AC line voltage used to power the module as shown in Chart 3. In a multi-control system, each module should have a separate fuse. -
Page 16: Operating Instructions
Bodine. Removing screws voids the Warranty. Operation 1. Disconnect the AC power to the Model 3984 and the motor control and double check all control connections as outlined in the motor control manual. -
Page 17: Internal Adjustments/Calibration
15). Internal Adjustments/Calibration The Model 3984 is factory adjusted to provide a VOUT signal of 0 to 10 VDC for a 0 to ±10 VDC signal applied to VIN. The polarity of the output voltage is always positive regardless of the input. -
Page 18: Max Speed Potentiometer
VDC can be used to operate the motor at its full rated speed. To adjust the MAX trim potentiometer: 1. Apply the desired voltage or current signal across terminals VIN1 or VIN2 and ICOM on terminal block TB2. 2. Adjust the MAX potentiometer until the motor RPM reaches the desired level. www.bodine-electric.com... -
Page 19: Troubleshooting
The charts on the following pages provide assistance in troubleshooting common problems which occur during normal installation and operation. If the problem persists, contact your source of purchase or a Bodine Authorized Service Center and describe the problem in detail. Do not disassemble the product unless authorized by Bodine Electric Company. - Page 20 DIP switch DS1, lever 4 Turn DS1:4 to ON position NOT CHANGE is in the OFF position DIRECTION WHEN POLARITY OF VIN CHANGES *Note: The disable input should be activated or the disable switch closed when the motor is expected to remain stopped. www.bodine-electric.com...
