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 overridden 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 overridden 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 indicates

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 overridden by machine operator input.

Relay Mode

 requires no machine operator interaction 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.

User Mode Menu Screens

Use the Next key to step through all available User Mode menu screens. The display will revert to the User Mode

Home Screen after 30 seconds of inactivity.

Formula Selection

From the Home Screen, press the Scroll key to select programmed formulas (1-4).

NOTE:

 

Formulas with no amounts programmed may not be selected.

Start Formula (Push Button Mode Only)

From the Home Screen press and release the Enter key for less than 2 seconds to trigger manual dispensing.

NOTE:

 

To terminate wash formula before end of lockout period press and hold the Enter key longer than 2 

seconds, release, and wait 30 seconds for screen to revert to idle screen.

View Load Counter

From the Home Screen press the Next key once to display “L”. Load counter (all formulas) will toggle between “L” 

and load count since last clear.

ID/Mode

From the Home Screen press the Next key twice to display the operating firmware ID number and currently selected 

operating mode. The first two digits indicate a firmware ID number we may ask you when troubleshooting. The right 

digit indicates the current Operating Parameter (oP) selection (1= Automatic, 2 = Push Button, 3 = Occurrence,  

and 4 = Relay).
