SET UP & OPERATION
3.1
PROGRAMMING
3.1.1
Pump/S
olenoid run time:
By calibration (max run time is 10 minutes)
1.
Be sure the
DOSING
trimmer is set completely counter clockwise
2.
Locate the terminal labelled “TYPE” on the far left side of the circuit board
—
close this terminal with
the jumper to enter in CA
LIBRATION MODE.
(led are blinking red).
3.
While holding a measuring cup or flask under the outlet of the pump, press the “
Start Dosing”
switch
and release when the pump starts
(led is steady red)
. Let the pump or solenoid run until desired
amount of chemical
is dispensed then press the “
Start Dosing”
switch again to stop. (
led is blinking red)
and buzzer will sound (1 beep)
. The
OPL Basic
run time is now programmed. Repeat these steps if
new volume is required.
4.
Remove the jumper from the terminal “TYPE” and l
eave circuit open for “Operation” mode. (To prevent
loss of the jumper replace it over one terminal pin).

Default dosing time is 1 second.
3.1.2
Delay time:
(max delay time is 5 minutes)
You set the delay, using the trimmer
DELAY
on the circuit board
3.1.3
Lock
-
out time:
(max lock
-
out time is 75 minutes)
This feature defeats consecutive dispensing of product for a pre
-
determined interval. Select a combination of switches 1
-
4 to program total lock
-
out time.

Example: For 15 minute loc
k
-
out, set switches #1 and #2 to ON with all other switches OFF.
For maximum lock
-
out (75 min) set all switches ON.
For no lock
-
out, set all switches OFF.
3.2
OPERATION
3.2.1
Manual activation
Press the “
Start Dosing”
button on the cover or on the remot
e switch. The
OPL Basic
will begin counting down the
delay time (if used)
(the led is blinking green)
and will then run the pump/solenoid for the amount of time programmed
(the led is steady green)
. Once the lock
-
out time expires the pump/solenoid will be
ready to restart.
3.2.2
Signal activation
When the signal input on the circuit board receives a 20
-
240 VAC trigger signal for at least 3 full seconds, the delay
time (if used
-
the led is blinking green)
will begin counting down. Then the pump/solenoid wi
ll run for the amount of
time programmed
(the led is steady green).
Once the lock
-
out time expires the pump or solenoid will be ready to
restart.
(NOTE: If
after
calibrating and connecting the trigger signals you want to disable the manual feed
option, rem
ove the jumpers inside the front cover for the “
Start Dosing
” switches).
3.2.3
Lock
-
out time
The lock
-
out time is independent for the system with two dispensers.
During the lock
-
out time the led is blinking green.
3.2.4
Disabling the start button
There is a j
umper marked “Pump1” or “Pump2” on the display circuit board that can be used to prevent manual
activation in certain applications, or to allow manual activation by remote push
-
button only. This jumper only affects
the integrated start button. A remote sta
rt button, or trigger signal, can always be used to activate the pump.

When the jumper is ON (close), the on
-
board start button is functional.

When the jumper OFF(open), the on
-
board start button is disabled.
