Temperature Controlled Fill - B&C Technologies FM7 Computer Programming And Operating Instructions

Temperature Controlled 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 Agitation. 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
be selected from 30 to 93 degrees C. See
Appendix A for details on building a Prewash,
Wash, or Rinse cycle that uses heating.

Agitation
For the agitation function, after pressing
ENTER, you are asked to enter the agitation
(programmed earlier, see pages 8-10). When
you have confirmed the selection with ENTER,
the display shows:
RPM =
Enter the desired value and press ENTER to
confirm. In Prewash, Wash, Rinse, and Unroll,
the maximum speed is 100 RPM.
