2.0 INTRODUCTION
The GeoCenter is a self contained detergent monitoring
and dispensing controller combined with a rinse injector in
the same cabinet.
The system includes two (2) separate printed circuit control
boards, one each for the detergent control system and the
rinse injector, transformers for each, and a solenoid valve.
These components are contained in a housing that is com-
pact in size but provides easy access for adjustments and
servicing.
The Detergent Control System features include:
• S-2000 SENSOR must be used with the Geosystem
products.
• Two Pole Probe for soft to medium hard water and where
soft metals are not being washed in the machine.
The controller provides overshoot control by “pulse feeding”
detergent when wash tank concentration is near the desired
control point. Visual indicators signal concentration status
of the wash tank.
• A “FEED” light will illuminate when concentration is
below the set level.
• A “100%” light will illuminate when at or above the set
time to titrate the wash solution.
Consistent detergent control is achieved over a wide range
of wash tank temperatures through the temperature com-
pensation feature when using the S-2000 Sensor.
The detergent controller also indicates low power supply
to the system.
The Rinse Injector System features Include:
• Double roller peristaltic pump
• Squeeze tubes with different delivery rates for high or
low volume requirements.
• Variable speed DC motor, 3-36 RPM.
• Regulated DC Speed Rinse Control P.C. Board.
• Selector switch to run continuously or to time out within
51 seconds.
• Start delay of 0-10 seconds.
