DESCRIPTION OF CONTROLS
1. CYCLE-OFF-CONTINUOUS SWITCH
CYCLE:
The controller will meter a given quantity of color and will shut off for the remainder
of the cycle. Quantity metered is controlled by the setting of the thumbwheel switch. In this
mode, motor speed is automatically adjusted by the internal microprocessor based on the
time length of the previous cycle and the setting of the counter. A speed is selected that will
allow the feeder to stop approximately 1/2 second before the cycle ends.
OFF:
Will prevent the controller from running and will remove power to the computer
controls.
CONTINUOUS:
The controller will run continuously as long as 110-volt power is present at
the controller power cord. Speed is controlled by and directly follows the setting of the
thumbwheel switch. Energizing the "cycle" cord has no effect -with one exception; if the
RANGE switch is in the LOW resolution position (turned to the right) the motor will ONLY
run when the SIGNAL cord is energized.
2. MOTOR FORWARD/REVERSE SWITCH
This switch should be in the FORWARD position for all normal operation. Holding the
switch down in the REVERSE position will cause the controller motor to run backwards.
In LIQUID COLOR pumps, this will cause the liquid color in the tubing to be returned to its
source.
3. THUMBWHEEL SWITCHES
In the CYCLE mode, the thumbwheel switch setting controls the amount of color metered
per cycle. In the CONTINUOUS mode, the setting determines the RPMs of the motor
output shaft.
4. MODE SWITCH
The Mode Switch allows several SPECIAL functions. Located in the upper right corner of
the control panel, it can be turned with a small screwdriver.
NORMAL (mid position)
All functions work as described elsewhere. Approximately 1/16 turn of the motor can be
expected for every count on the counter or 63 turns of the motor for the maximum setting of
999. (This relationship may vary with non-standard models).
FRACTIONAL (left position)
