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
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. |
