4.0 USER MODE OPERATION
The Mercury dispensers four modes of operation are
described in this section.
Automatic Mode runs each pump program (program
= delay time + run time) upon qualified input to the
respective signal input. When on (not set to 000), the
Lockout Timer begins at start of first pump program
(beginning of delay time). During this lockout
period, no pump amount may run more than once
regardless of the number of times the signal input
occurs. Display indicates signal status, pumps
running, and lockout status. Machine operator selects
desired formula number with the Scroll key. Auto
Formula Select is always active, but may be overrid-
den by machine operator input.
Push Button Mode relies on a user push button
press to start the wash formula program. Auto
Formula Select is always active, but may be overrid-
den by machine operator input. The machine
operator selects the formula number with the Scroll
key, and then starts the wash formula program by
pressing and releasing the Enter key for less than 2
seconds. Pumps run as programmed via programmed
delay and run times. During the lockout time, all
button presses to start the formula program are
ignored except, Password input. The display indi-
cates pumps running and lockout status.
Occurrence Mode is an alternate automatic logic
where signals from input numbers 1, 2 and 3 act as a
single logic input signal. Signal occurrences are
counted (simultaneous input signals count as one
signal occurrence) to determine when each pump
runs, based on pump-assignments in the Assign
Pump “A1A” screen in the programming menu.
Pumps 1 and 2 have two programmable amounts, A
and B, which are treated in Occurrence Mode as
separate pump programs. Display indicates signal
status, pumps running, and lockout status. Auto
Formula Select is always active, but may be overrid-
den by machine operator input.
Relay Mode requires no machine operator interac-
tion since all dispensing system control is turned
over to the washing machine control system.
NOTE: Password input and/or power failure
resets the lockout timer and ends the
wash load in all modes.
