The figure at the right shows a typical fill
bath.
Step 1 - Fill to a water level with hot
water. Watchdog timer of 9:00 allows
time to fill before an alarm is generated.
Step 1 ends when the water level is
reached.
Step 2 - Chemical 2 output is on, Relay
12 (injection flush) is on (not required
for machines with plastic vacuum
breaker). Step 3 ends when a time of
1:00 elapses.
Step 3 - Top off step, same as step 1,
except for a shorter Watch Dog Time.
Step 4 - This is the wash step. No
relays/outputs are on. Step 4 and the
entire cycle are complete when a time of
7:00 elapses.
A note about the Watch Dog Timer:
The Watch Dog Timer makes sure that
the machine reaches level or
temperature in a timely fashion, and
ensures that the water or heat doesn’t
stay on until someone notices a
problem. Don’t be confused - Step 1 will
end when the programmed water level is
reached, NOT when 9 minutes has
elapsed.
