Soap Level Detection
This is an optional feature that your system may not be equipped with. There are 2 inputs
that allow connection to external dry contacts that allow detection of 2 soap levels. Soap
Level #1 input warns of low soap levels, and Soap Level #2 warns that there is no more
soap. In the case of low soap levels, the unit is still useable, but the scrolled message in
Power-Up and OFF states indicates L O W S O A P L E V E L - R E - O R D E R . If soap level
drops such that Soap Level #2 detects it, then the unit is no longer operational at the end of
the current cycle. The unit will remain in Power-Up or OFF states and scroll A D D S O A P

Dry Fire Detection
If the heater sheath temperature ever reaches the Dry Fire Threshold, then the situation is
called a dry fire and the control shuts off the outputs and switches to the Power-up state.
This overrides any effective mode of operation. This is the normal way to detect that the
tank has been drained.
called a dry fire and the control shuts off the outputs and switches to the Power-up state.
This overrides any effective mode of operation. This is the normal way to detect that the
tank has been drained.
The algorithm used to detect this can be fine-tuned by the OEM. There are 2 low-level
parameters for this. The Heater is pulsed every Dry-Fire Period time, each of these pulses last
0% to 100% (Dry-Fire Duty) of the Dry-Fire Period time. For example, the Heater can be on
30 milliseconds every 100 milliseconds, which corresponds to a 30% duty at a rate of 100
milliseconds. With these parameters, the OEM can select the best compromise between fast
response time (detection of the empty tank) and low energy consumption of the appliance.

Change Water Feature
The total Wash time is constantly monitored. Whenever this reaches Change Water Time, the
unit finishes its current wash cycle if needed, and then displays C H A N G E W A T E R until a
dry fire is detected (a new cycle cannot be started before the tank water has been changed).
At this point, the Power-up state then becomes active and the display is cleared.

At this point, the Power-up state then becomes active and the display is cleared.
This condition will remain active (even through a power interruption) until 1 of 2 things
happen: (a) the tank is actually emptied and the Dry Fire Detection resets the total wash
time; (b) the user may “clear” the condition (reset the total wash time) by pressing all 3
language keys at the same time. This last is useful for demonstration purposes, where one
might not want to really drain the unit.
