OPERATING INSTRUCTIONS

The display now shows:
Pressing STOP will cancel the programming and abort any parameters you have entered. To save,
press ENTER. Now the start of a new step will be indicated. For two seconds the display show:
The display then changes to:
At this point, you may continue assign steps to the cycle using the same programming sequence as
used for step 1. If programming is complete, press STOP. the
You may now program another Prewash cycle, or select one of the other cycle types and continue
programming. To exit from cycle programming, press RESET.
Cool down Phase
The cool down phase allows you to specify a temperature to reach before draining the machine.
There are five parameters to be programmed: Minimum Level, Maximum Level, Temperature,
WDT, and Motor. The cool down phase operates as follows:
¾
The water is drained to the minimum level as mentioned above.
¾
Cold water is then added up to the maximum level as mentioned above, and the
temperature is monitored.
¾
Draining and filling continue until either the temperature is reached, or the WTD
(watch dog timer) has expired.
The motor profile chosen is active throughout this step.
Load Balancing / Temperature Controlled Fill
The Load Balancing option is essentially a temperature controlled, or modulated, fill. Cold and Hot
water are added to the machine while the temperature and level are monitored. Four parameters
must be entered: Level, Temperature, WDT, and Motor. The option functions as follows: Cold or
Hot water is added to the machine depending upon the temperature set (Hot if the water temperature
is lower than programmed or cold if it is higher) until the programmed water level is reached. Then
the next step of the cycle can begin. During this phase, the WDT (watch dog timer) is active, which
will flag a fault if the fill time is longer than the programmed WDT. The chosen motor routine is
active for this entire process.
Heating
Throughout the programming of the steps, when heating is inserted, this tells the control to regulate
the temperature. In a step that ends with a required temperature, the heating value must be greater
than or equal to the step ending temperature. For example, if 50 degrees was set for heating, but 70
degrees was required to end the step, the machine could never reach 70 degrees, causing a fault
from the Watch Dog Timer. In cases where the step is ended by time or level, the temperature can
STORE?
