seconds. Loads are counted each time the highest
pump number with a programmed amount is run.

Occurrence Mode paces the dosing of products off
the washer fill valves by counting each time the
machine fills to identify the occurrence-sequence of
machine steps. This mode of operation is ideally
suited for machines with no chemical supply signal
outputs, such as domestic style top load washers.

While all three of the trigger signal inputs are active
and may be used, typically only two will be used.
Typical trigger signal wiring would be one of the
available trigger signal inputs wired to one fill valve,
and another trigger signal input to the other fill valve
(typically the hot and cold fill valves). Since the
dispenser responds to any of the trigger inputs, it
does not matter which input goes to which fill valve.

The dispenser counts the machine fill occurrences
and runs pumps based on an assignment of the
pumps to the machine step sequence.

A dispenser wash formula consists of up to 5
programmed pump amounts (1a, 1b, 2a, 2b, and 3
are the five programmable pump amounts from three
physical pumps). Any of these available amounts
may be programmed to any (up to 9) machine step.

The Lockout feature is available to be sure that each
programmed pump amount only runs one time per
dispenser wash formula. The dispenser wash formula
is terminated 5 minutes after the last pump pro-
grammed in a sequence runs, or the Lockout period
(when on) ends, whichever comes first. If the load
needs to be restarted for any reason, the dispenser
wash formula may be terminated early by pressing
the Enter key for two seconds.

Relay Mode runs pumps for the duration of washing
machine supply signals. This mode is typically used
on fully programmable microprocessor controlled
washing machines where the installer opts to control
the dispensing equipment from the washing machine
control system instead of the dispenser’s control
system. The load counter increments each time pump
one is run in Relay Mode.

The Mercury offers four operating modes for
maximum flexibility in small OPL and Top Load
washer laundry applications. Automatic Formula
Selection may be used in all modes whenever a spare
washer supply signal output is available that may be
programmed to the second. The following sections
describe each mode’s unique operation specifications
in detail.

Automatic Mode is a basic mode of operation similar
to Timer Mode in our Eclipse and Orion dispensers.
Each trigger signal input number matches the
corresponding pump number (i.e. trigger 1 = pump
1, trigger 2 = pump 2, etc.). Pumps can be delayed
after trigger signals for occasions where pump delays
are required to prevent dosing on dry linen, etc.
Pump  delay times are programmable in seconds.

Pumps 1 and 2 have two product levels, A and B.
The A level dispenses on the first occurrence of the
trigger signal in a formula. The B level dispenses on
the second occurrence of the same trigger signal
within the same formula. Pump 3 only has one
product level.

The Pump Lockout feature, when turned on, prevents
any unwanted pump activations due to false signals
from washers that send noisy or multiple output
supply signals. 

Loads are counted each time the highest pump
number with an amount programmed (unique to each
formula) is run. The Pump Lockout timer and
(pumps 1 and 2) A/B levels will be reset 5 minutes
after the count pump runs or the Lockout period
ends, whichever comes first. If the load needs to be
restarted for any reason, the dispenser wash formula
may be terminated early by pressing the Enter key
for two seconds.

Push Button Mode is intended for manual operation
where the machine operator selects a formula and
presses the Enter key to start and run the dispenser
wash formula. A dispenser wash formula consists of
up to 5 programmed pump amounts (1a, 1b, 2a, 2b,
and 3 are the five programmable pump amounts from
three physical pumps). Pump Delay times (pro-
grammed in minutes) stagger the programmed pump
doses throughout the wash load.

The Pump Lockout feature (programmed in minutes)
prevents the machine operator from starting multiple
doses in the same wash load. If the load needs to be
restarted, the dispenser wash formula may be
terminated early by pressing the Enter key for two
