Operation and Troubleshooting
Electronic Control Input Connections:
Optional Interface boards provide electrical
isolation between the input signal and the brushless DC motor control circuitry, and are
recommended for motion control applications requiring electronic control of motor speed,
rotational direction, deceleration, and braking.
Electronic Speed Control (optional):
Motor speed can be controlled with a 0 to +10 VDC
isolated signal with 0.1 mA current capability in lieu of the manual speed potentiometer. This
speed control input should be connected to terminal S2 on the control board. The common
side of the signal must also be isolated and connected to terminal S1 on the main control
board.
PLC Logic Signal Control of Braking, Direction of Rotation, and Deceleration:
On the furnace, motor braking (or disable), direction of rotation and deceleration is controlled
using optically isolated logic signals from the PLC programmable controller.
WARNING
Never rely on logic circuitry as a means of disabling the motor or control. To prevent unsuspected
mechanical motion and potential injury, the 115 VAC power should always be disconnected
whenever logic circuits or the driven equipment are serviced.
Exercise extreme caution when using Programmable Logic Controllers (PLCs). Although the
output modules are optically isolated output modules, their output commons may be
connected to other circuitry either within or connected to the PLC. In such cases, the PLC
outputs should be isolated from the control board, by a relay or by an electronic isolation
module, to prevent damage to the PLC or the ABL Control.
When a Programmable Controller with a relay output module is not available, AC or DC
outputs from the PLC can be used to drive separate relay coils. See PLC user's manual for
application information. See Figure 7 to determine how to connect relay contacts to the
ABL-3911C.
Figure 8 - Connection to Model 3984 Isolation Interface
Signal Isolation Using the Bodine Model 3984 Interface Module:
Follow the installation
instructions provided with the module to isolate the input signals between the control
electronics and the ABL Control. See Figure 8 for connections.
