3.6.1.

Photocoupler, continued

In blending dispensers the LED’s in each photocoupler are wired in series, as
shown in Figure 3-4. Because of this a problem in one of the photocouplers
can cause symptoms to be shown on the other end grade. For instance if one
of the LED’s in the Lo product photocoupler was to become an open circuit
the five volts would not be supplied to that LED in the Hi product
photocoupler. This would cause symptoms to appear on any Hi product sales.

3.6.2.

Pulser Disc

The pulser disc is a plastic disc with square holes cut around its outer edge. It
is connected to a shaft which is turned by the meter. The holes in the edge of
the disc pass between the LED’s and the phototransistors. This alternately
blocks and reveals the infrared beam to the phototransistors creating the
pulses.

3.7.

SUCTION PUMP MOTOR

The pump motor used in Wayne suction pumps can be either a 1/3 or 3/4 horsepower
motor. Either of these two motors can be operated on either 110 VAC or 220 VAC,
depending on a switch setting. The voltage selection switch is located on the side of the
motor, and is secured by a sheet metal screw. To change the operation of the motor:

•

Remove the sheet metal screw which holds the switch in position.

•

Move the selector switch to the desired location.

•

Replace the screw to lock the switch in its new setting.

The pump motors are switched on by a relay located in the dispenser junction box. This
relay is pre-wired to the relay select line from the solenoid drive board. The load side of
the relay contacts are factory wired, therefore, the only on-site connections which need be
made are the two input wires to the relay contactors.

3.8.

BLEND MOTOR

(Blenders only) The blend motor is an electrical stepper motor which is used to adjust
the blend valve as product is being dispensed. The stepper motor receives voltage pulses
from the solenoid drive board; each of these pulses causes the motor to move a known
amount. A linkage interconnects the motor and the blend valve; therefore as the motor
moves the blend valve moves with it. The blend motor, one for each side of the dis-
penser, is located in the dispenser junction box.
