OPERATING MODES 

Normal operation: 

The system is capable of 8 user selectable formulas 
with each formula having unique run times and delay 
times for each pump. Signals from the washer trigger 
the pumps, then the On-Premise Pro’s microprocessor 
takes control to count down delay and/or run times. 

Wash formulas can be selected by either of the two 
following options: 

 

The machine operator can select the formula using 
the formula SELECT button to choose the appropriate 
wash formula before the washcycle begins. 

 

Auto formula select can be used to allow the washer 
to control the formula choice with a signal. 

The first time pumps 1 - 6 are signaled, they will run 
―level‖ 1. The next time these pumps are signaled in the 
same formula, they will run ―level‖ 2 providing that any 
signal lockout time (if used) has expired. Pumps 1 - 6 
will not run again until the Load Count Pump is signaled, 
formula number changed, or the RESET button is 
pressed. 

 

No more than 3 pumps (if applicable) should be 
programmed to run simultaneously. 

 

Pumps 1 - 6 are the only pumps with ―two level‖ 
capability. Level 1 can be ―skipped over‖ if desired, by 
not programming any pump run time for that level. 
When the first signal is applied, no pump action will 
occur — the second signal will then activate the 
second level as usual. 

Flush mode: 

The Flush Pump turns on with any pump running, then 
activates its own programmed run time when the pump 
shuts off. The system ―looks‖ for contact at the flow 
switch terminals (see wiring diagram) to verify proper 
flush. If a flow switch is not used, jumper JP1 should be 
in place. A ―flush error‖ happens when no contact is 
detected (switch or jumper) at the FLUSH ERR 
terminals while only the Flush Pump runs. Flush errors 
are indicated by the Remote Control flashing and ―F‖ in 
the pump window. Also, the buzzer (optional) will sound. 

Programming pump ―F‖ is only required for systems that 
will inject with a flush manifold. 

 

Relay mode: 

The intended use of relay mode is for machines that are 
microprocessor controlled. The pumps run for as long 
as their respective signals are present. The system ―by-
passes‖ its run time and delay time capabilities during 
relay mode operation. 

Formula numbers are not selectable in relay mode (as 
they are not needed) — an ―r‖ will be displayed in the 
formula number window indicating the system is in relay 
mode. Flush mode can be used in relay mode if 
chemicals are to be flushed with water to the washer. 

To set relay mode, enter the access code, then use 
FORMULA SELECT to choose formula ―r―. Set the load 
count pump as explained in the Load Count section. 

(

Note: 

There is a one second qualifying time in relay 

mode. For the pump to run for 10 seconds the signal 
must be set for 11 seconds.

)

 

Drain mode: 

Drain Mode maximizes the versatility of the OP-Pro by 
providing a simple and reliable signal interface to 
washers that do not have typical supply signal 
connections, or where the washer’s supply signals are 
not operating correctly. 

Installation time is quicker, as there is only one signal 
source required from the washer for Drain Mode to 
operate. See page 11 for complete details.
