BUTTON FUNCTIONS
PRGM: Steps you through the setup program.
PRIME 1 (
Ø
): Manually activates pump 1 and shows clock when not programming.
Advances numbers when programming.
PRIME 2 (
×
): Manually activates pump 2 (if applicable) and shows clock when not programming.
Advances numbers when programming.
SET: Not used.
SECURITY FEATURE — REMOVE JUMPER JP1 TO PROGRAM
To prevent unauthorized tampering, the events and time/day setting can be “secured” by placing a jumper on the
JP1 pins on the back of the MT-300 circuit board. The jumper acts like a lock and key...when the MT-300 is secured
(jumper on) the display will show “SECU” if the PRGM button is pressed. The PRIME buttons are not affected and
will still function in their normal manner. Removing the jumper allows the MT-300 to be programmed or to change the
time of day clock. Replace jumper when done programming if you wish to secure the system.
HOW TO SET THE SYSTEM
(1) Press the PRGM button — set the clock to the current time of day. Use
×
/
Ø
to set the clock (note AM/PM).
(2) Press PRGM button again — PE 1 will be displayed. PE = Pump Events (“on times“) needed per day. Use
×
/
Ø
to set the number of pump events per day that are required.
NOTE: The system will activate only the number of pump events indicated by the PE #.
(3) Press PRGM button again — E 1 will be displayed indicating that you are going to program the first event.
(4) Press PRGM button again — pump start time will be displayed. Use
×
/
Ø
to set the pump start time (note AM/
PM).
(5) Press PRGM button again — pump run time will be displayed. Use
×
/
Ø
to set the pump run time (min:sec).
(6) a: Press PRGM button again — E 2 will be displayed if you selected more than 1 pump events (PE) per day.
Program all pump events the same as the instruction in steps 4 & 5.
b: After all pump events are programmed, pressing the PRGM button will return you to the blank display.
(7) To review your pump programming, press the PRGM button and slowly step through the program. Make
changes as necessary referring to the above instructions.
* NOTE: If you get lost in the program, press the PRGM button until you return to the blank display.
Follow the instructions above.
* TIP: If you hold down any of the programming buttons for 2 seconds the numbers will scroll much faster.
HOW TO EASILY CALCULATE PUMP RUN TIMES
(1) Decide number of ounces (volume) of product required.
(2) Pump 30 seconds of product into a measuring cup and calculate: Ounces/Second = Ounces Measured ÷ 30
seconds.
(3) Time to be programmed for the amount of product: Time (Seconds) = Ounces Required ÷ Ounces/Seconds.
Example:
Volume Required is 10 Ounces.
Let’s say that 6 ounces of product is pumped in 30 seconds. The resulting flow rate would be 0.2 ounces/second
(using the calculation previously mentioned in step 2 which would be 6 ÷ 30 in this example).
Therefore, the pump run time to be programmed will be 50 seconds (using the calculation previously mentioned in
step 3 which would be 10 ÷ 0.2 in this example).
