AIRSTREAM™ SERIES DRYER

Electrical Overview

Pro Airstream™ Dryer
The following is an explanation of the key electrical components and their functions in the Pro Airstream™
Dryer. For more information, refer to the sub-plate image, which provide an illustration of the component
labels referenced in this section.
Circuit Breaker
Circuit breaker provides 120 VAC power and the means of disconnecting that power. If the handle of the
breaker trips to the off position, an electrical short circuit has occurred. The following may have caused
problem.
• DC motor controller has short circuited: Turn off the power. Isolate DC motor from motor control by
disconnecting the motor from the terminal marked “M + and M -“. Reset circuit breaker. If breaker
remains set, the problem is in the DC motor. If the circuit breaker trips, the problem is with the motor
controller. If this is the case, replace the motor control.
Motors
There are four motors on the Pro Airstream™ Dryer. Three of the motors are used for air production.
They operate on three-phase power supplied by the car wash controller. The fourth motor (DC motor)
drives the Top Nozzle Pivot Arm and provides the means for touch-free control. The DC motor contains
two electric brushes that in time WILL have to be replaced.
DC Motor Controller
The DC motor controller is a circuit with sever adjustments and fuses. It’s purpose is to convert 120VAC
to DC voltage up to 90VDC to be used by the DC motor. This allows the motor to raise and lower the top
nozzle accordingly. A properly functioning DC motor controller allows instant torque and movement of
the top nozzle in both directions.

CAUTION

All adjustments are set at the factory and should not require change. If you feel the setting need
to be changed from the factory settings, contact Belanger, Inc. Customer Service Department A
slight changes in any one of the settings can greatly effect other settings on the board.
There are three fuses on the motor controller. There is a 20 Amp fuse on the 120 VAC line feeding the
unit that protects the unit from a fatal failure. A 4 Amp ABC fuse on the armature line of the DC motor to
protect from motor failure or the possibility that the motor jams. The final fuse is a .150 amp control
board fuse. This fuse is primarily there to protect the transformer and other components on the motor
controller.
Speed potentiometer POT1 controls the electric speed control of the Top Nozzle Pivot Arm in the
DOWN direction. The down speed of the Top Nozzle Pivot Arm is also controlled by the mechanical, oil,
and pneumatic settings (see “Adjustment” section). The DC motor drives the cam that rides along at this
mechanical speed. The DC motor cannot drive or force the Top Nozzle down.
Speed potentiometer POT1 may require slight adjustments to accommodate conveyor line speed.
There is no speed control for the up direction. The unit is set at the factory for maximum up speed.
