DELIME
Delime In Progress Screen appears after Continue is pressed on previous screen.
Heater comes on after make / break validation of High probe but not prior to
Continue button on previous screen being pressed. Unit refills to High probe
after heat comes on/High probe break. Unit heats to ready temperature (approx
15 min) and heats for an additional 20 minutes. Heating and 20 minute counter
is stopped during door opening and the spinning circle will also stop. Water fill
or drain will continue during door openings and progress bar and spinning circle
will continue. Door alarm functions only during heating cycle in Delime and will
sound after default time setting if door is left open. Fill valve operates during
heating cycle to maintain water at High probe. Probe based Delime: After heating
is complete, unit drains to Low probe. If no Low probe transition is seen within
(2, 4) minutes of High probe transition, Cleaning popup is shown. Reservoir refills
to High probe. If no High probe transition is seen within (2,4) minutes , Cleaning
popup is shown and unit drains to Low probe. Reservoir refills to High probe.
Drain to Low Probe and drain to empty. If there are no probe failures during
third fill/drain cycle, Delime complete screen is displayed. Progress bar: 25%
at High probe (M/B/M), 50% after heating and end of second fill at High probe
(M/B/M), 75% after drain and refill at High probe (M/B/M), 95% on low probe
break on last drain and 100% at empty (time based). When complete, an alarm
will sound (4 beeps) and the notification screen will display and remain visible
until acknowledged (Restart - goes back to Start Up screen) or unit is powered
off via the power switch. Once Delime is complete, the Delime Date is recorded /
updated, the Delime counter is reset to zero and the Delime button is reset to “no
color”. If control does not recognize transition on Low or High probes during third
fill, Cleaning pop up occurs and drains to empty. Unit waits until user selects
Repeat Delime or shuts power off. If Repeat Delime button is pressed, the unit
returns to the Prepare Cavity screen and waits until the “Start” button is pressed.
After filling is complete, user shall add additional delimer and press Continue.
Once Continue button is pressed, heater will energize (door must be closed). If
control does not recognize transition on High probes or Low probe during third
drain, Cleaning pop up occurs and unit continues to drain until user selects
Repeat Delime or shuts power off. Note: Low probe circuit relay is defeated in
delime to allow the heating to function even if low probe is fouled.
