Fill Error Time: MM
Min=00, Max=20 05
The range is from 00 to 20 minutes. Set the number of minutes
that the machine can try to fill before the water valves close and
the operator signal starts. When the error occurs, push
to open
the water valves and start the timer again.
If you set this value to 00, then the machine will start the operator
signal if the machine does not fill in less than 10 minutes. The
water valves remain open.

CHEM 1 INJ TIME: SSS
FORMULA 01 030
Display of Chem 1 inject time configuration decision. Some
chemical systems use the duration of the chemical 1 injection sig-
nal to determine which wash formula is running. Only the injec-
tion time for chemical 1 is configurable; all other chemical signals
are fixed at 30 seconds. By default, Chem 1 inject time for each
formula is 30 seconds until changed. The minimum value is 1 sec-
ond; the maximum value is 255 seconds (4:15).

The normal duration for all chemical injection signals from this controller is 30 seconds.
This period often allows delivery of the desired amount of chemical when pump sizes and other
factors are used to control chemical volume more precisely.
Installations requiring more precise chemical metering may use programmable chemical supply
systems (provided by others) to select chemical amounts according to the washer-extractor for-
mula. Typically these chemical systems use the duration of the washer-extractor injection signal
for Chemical 1 to determine which formula is running, then select the corresponding chemical
program for that wash formula.
When the chemical supply system determines the wash formula and selects the appropriate chem-
ical program for quantities, the chemical system still needs to know when to inject each chemical.
The chemical system monitors the washer-extractor controller for chemical signals in each step
calling for chemicals. When the washer-extractor requests a specific chemical, the chemical sup-
ply system injects the programmed quantity of that chemical.
For example, the E-P Express
®
controller may be configured so the Chemical 1 signal is five sec-
onds in formula 01, ten seconds in formula 02, and 15 seconds in formula 03. When the washer-
extractor controller signals for Chemical 1 to be injected, the Chemical 1 output relay is turned
on for the configured duration. The chemical injection system then determines which formula the
