GENERAL INFORMATION
About This Manual
This manual contains the basic information needed to install and operate a Continouus Belt IR
Furnace Drive Motor with a Bodine Model ABL-3911C Control.
Safety Standards
This equipment is 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), and U.L.
CONTROL DESCRIPTION AND FEATURES
The ABL-3911C Brushless DC Motor Controls are chassis style controls, mounted into the
furnace motor control enclosure at the furnace exit. They operate from a nominal 115 VAC, 50/60
Hz. Power source and provide electronic commutation and phase current switching needed to
operate brushless DC motors. DIP switch selectable current limit settings allow the controls to be
used with several fractional horsepower motors and gearmotors.
The ABL-3911C provides a 130 Volt filtered output for improved form factor, plus a built-in
dynamic braking module. It allows motor speed to be manually or electronically controlled.
Motor direction of rotation, braking or disabling, and soft starts and stops can be controlled with
manual switch inputs, but are generally controlled by the furnace programmable logic controller
(PLC). Since the control's signal common is not at ground potential, interface circuitry is required
to isolate logic signals from the control. Trim potentiometers on the control board allow additional
fine tuning of minimum and maximum speed settings, torque, acceleration and deceleration time.
A built-in smart reversing circuit prevents plug reversing by braking the motor to a stop before
changing its direction. A built-in shutdown circuit disables the control during overvoltage, under-
voltage, or invalid commutation sensor state conditions.
Specific motor sizes which can be used with this control are listed in the Chart in Table 1.
Accessory Items
• Model 3983 Connection Cable Assembly - connects Bodine brushless DC motors to ABL-
3911C and ABL-3921C controls. Length: 6 foot.
• Model 3982 Extension Cable - extends cable between motor and control by six feet. Both ends
equipped with circular connectors for easy connection between Model 3983 Cable and motor.
Length: 6 ft.
• Model 3984 Isolated Interface Module
Inspecting the Control
Carefully examine the control (and any optional kits or parts) to verify part number. Parts errors
should be reported to the manufacturer.
Before installation or troubleshooting, review the application to confirm that the proper motor and
control have been selected. This confirmation should be done after reading this manual and all
applicable safety standards.
