OPERATION
Detergent — Probe Mode
The system has the option of using a conductive. With
the detergent signal “on”, the probe senses detergent
concentration. When concentration drops below the
setpoint, the control automatically turns on detergent
feed. As the detergent feeds, the control senses the rate
at which the detergent concentration is approaching the
setpoint. The control then begins to pulse feeds to
prevent over-use of chemical. The pulse feed rate will
depend on how fast the setpoint is being approached.
The detergent alarm will sound if the setpoint is not
reached within the alarm delay time period. The alarm
can be temporarily silenced. A “feed limit” feature allows
you to set the unit to automatically shut off the detergent
feed when the alarm has been activated.
Detergent — Probeless Mode
Controls detergent concentration without a probe, based
on timed detergent feed modes. Initial charge time feeds
detergent to bring the dishmachine to working
concentration when initially filled with water. The initial
charge can be activated by a detergent signal, or by the
rinse signal (of 30 seconds duration, or longer) when
using door mode. The initial charge counter will
increment for each activation.
Recharge time feeds detergent to maintain detergent
concentration as rinse water dilutes the dishmachine.
The recharge is triggered after a specified number of
racks passes through the machine.
Rinse Pump
The rinse pump will operate whenever the rinse signal is
energized. The rinse delay feature will postpone the
activation of the rinse pump until the delay time has
expired. The rinse limit shuts down the rinse pump after
the signal has been present for a selected time. Rinse
delay and rinse limit are functional with door machines
only.

TO PRIME DETERGENT: To prime detergent (pump
or solenoid) hold down the UP and DOWN buttons at
the same time.

TO PRIME RINSE: To prime rinse pump hold down
the SCROLL and UP buttons at the same time.

During normal operation, the low detergent alarm
(probe mode) can be silenced by pressing the ENTER
button. The audio alarm will turn off for the alarm delay
period of time to allow the chemical container to be
checked and changed if necessary.
De-Lime Mode
Press ENTER and SCROLL until de-lime mode shows
on the display. Chemical injection will be halted while de
-lime mode is on but will resume normal operation when
turned off. The unit will automatically exit de-lime mode
after 10 minutes, or pressing ENTER and SCROLL.
PROGRAMMING

Changes will not be saved.

To change the value of any numeric setting, press
SCROLL to select the digit you wish to change, then
use

/

to change the number. The digit will flash to
show you which one is selected.
When you’re ready to get started, hold down the ENTER
button until you see ENTER PASS CODE (about 3
