OPERATION
E
Detergent — Probe Mode
N
With the detergent signal "on", the conductivity probe
G
senses detergent concentration. When concentration
L
drops below the setpoint, the control automatically turns
I
on detergent feed. As the detergent feeds, the control
S
senses the rate at which the detergent concentration is
H
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. A "feed limit"
feature allows you to set the unit to automatically shut
off the detergent feed when the alarm has been
activated.
If a temperature compensating probe is used, the
control will automatically make adjustments for the
change in conductivity that is caused by temperature
variation.
Detergent — Probeless Mode
Controls detergent concentration without a probe, based
on timed detergent feed modes. Initial charge time feeds
detergent
to
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.
Sanitizer Pump
A menu selection sets the sanitizer pump to operate
with detergent feed, or with rinse feed. The sanitizer
pump will run simultaneously with detergent or rinse,
whether using probe or probeless mode, rinse delay or
rinse limit.

ADDITIONAL FEATURES
De-lime Mode
During normal operation, hold the SCROLL and DOWN
buttons simultaneously until "De-Lime Mode" appears
on the display. All chemical feed of the Digi Set will be
halted while in the de-lime mode. Press the SCROLL
and DOWN buttons again, or cycle main power to the
unit, to exit the de-lime mode. Otherwise, the unit will
automatically exit de-lime mode after 10 minutes.
Low Product Alarm
Digi Set has a low product detection feature that will
activate the alarm when there is a low supply condition
with any of the products. When the alarm is activated,
the pump for that product will be shut off until the
product supply is restored. You can choose to "over-
ride" the alarm if necessary, and allow the pump to
continue, despite the low product condition.
The detergent low product alarm input is only selectable
when using probeless mode. This is because probe
mode already has a low product alarm feature. The
rinse and sanitizer alarms are available in all modes.
The Digi Set circuit board has input terminals for the
connection of various types of switches that detect the
to
working
product
level
conductivity sensor). When the product supply is low,
the switch opens and activates the alarm. When the
product supply is restored, the switch will make contact
and shut off the alarm.
BUTTON FUNCTIONS
•
ENTER: Holding the enter button for 3 seconds
(approx.) switches between run and program modes.
Enter also advances through programming menus.
•
SCROLL: The scroll button moves the position of the
cursor in menus where text or number changes are
done. The scroll button will "wrap around" at the end
of a line of characters, meaning that the cursor will
advance to the beginning of the line automatically.
The scroll button toggles between choices in menus
that have selectable settings. The scroll button also
shows the rack count and initial charge count during
normal operation.
•
UP ( ): Increases numeric values or advances
upward through available characters. Hold the button
down to rapidly advance. The UP button also acts as
rinse prime during normal operation.
•
DOWN ( ): Decreases numeric values or advances
downward through available characters. Hold the
button down to rapidly advance. The DOWN button
also acts as sanitizer prime during normal operation.
