used. (No jumper for S-2000, S26 position installed for
two-pole cell).
2. Check TITRATION DIP switch setting. Temporarily increase
the setting to see if feed occurs.
3. If Two Pole Probe is used, remove the wire from terminal
#10. If detergent now feeds, the cell or cell wiring is shorted.
Repair or replace as needed.
4. If S-2000 Sensor is used, temporarily remove the brown
wire from terminal #15. If feed occurs, the thermistor in the
sensor may have failed and the sensor must be replaced.
As a backup, the unit can be run in this condition, although
temperature compensation will not function. Reset the
5. If S-2000 Sensor is used, remove the blue and white wires
from terminals #13 and #14. Temporarily place a jumper
a. If detergent feed occurs, replace the S-2000 sensor.
b. If detergent feed does not occur, replace the detergent
controller PC board.
the solenoid valve.
2. With power on, check for 24 volts at terminals #20 and
#23. If 24 volts, replace Detergent Controller P.C. Board.
NOTE: First determine if the wash tank concentration is
actually increasing. If not, there is no detergent being
delivered to the machine, or the detergent is not feeding
into the wash tank. Check for: proper water ow to the
dispenser; proper operation of the dispenser spray nozzle;
ow through the injection point into the machine.
1. Try a lower titration setting. If the dispenser stops

c. If using the S-2000 Sensor, place a jumper wire across
terminals #12 and #14. If detergent does not stop
feeding, replace Detergent Controller PC board. If
detergent stops feeding, replace the sensor.
2.
If the controller does not stop detergent feed when
adjusted to the lowest dispenser setting (all TITRATION
DIP switch positions off):
