Press the ▼ arrow to display over mA set point N°2 and with ◄ ► arrows select either STOP or CONTINUE.
This will either permit or inhibit dosing if the set point is passed.
Then press the ▼ or ▲ arrow to escape and the START button to recommence dosing.
The mA will then be displayed along with the input mA signal strenght. (Fig. C)
2.4 Proportional in PPM (parts per milions)
This function allows to set in a direct way the PPM value desired in relation with the
impulses received from a water meter. Considering the passing water, the solution
concentration to dose and the solution quantity each impluse, it is necessary to set the
number of PPM of the product in the water.
Programming: push the button START/STOP to put the pump in pause and enter the
programming mode. With the arrows ◄ ► run the menu till appears PPM.
- With the arrow ▼ you can enter the menu [L-I CONT] (defined standard 1.00) though
◄ ► it is possible to set freely the liters per impluse supplied from the water meter
connected to the pump with reference to the following table.
L/I CONT 0.1 0.25 0.5 1.00
Imp/lt 10 4
L/I CONT 1.5 5
Imp/ 10lt 4 2
- Pushing again the arrow ▼ you ca enter the menu [CC/INJECTION] (defined standard to 0.01CC) through ◄
► it is possible to set freely the quantity each injection. To set the exact value of the impulse flow of the pump,
the procedure is the following:
1) Install the pump on the plant
2) Provide with a cylinder with the graded scale
3) Switch on the pump in the manual function and dose 10 injection (otherwise it can be used the 1xN function
to avoid counting)
4) Draw attention to the quantity of the supplied product and dived the value in 10 parts (or N)
5) Set on the display the obtained value
- Pushing again th arrow ▼ you can enter the menu [SET PPM] (defined standard 1) through ◄ ► it is possible
to set the value in ppm that you desire to mantain in the plant (0.1-20000)
Press the ▼ or ▲ arrow to escape and the START/STOP button to recommence dosing with the new settings,
the display visualizes the option you have selected (see Fig. D).
2.5 Alarm (to be used only with additional Injection sensor)
This is an auto-learing funtion that allows the pump, after giving a number of reference, to
compare the number of electrical impulses with the ones of a injection sensor connected to the
delivery; If this number is higher than the number set in (MAX DIFF), the pump emits a loud
alarm signal (BUZZER) that can be repeated also is the distance through the a relays contact
and is stops the pump.
Programming: push the button START/STOP to put the pump in pause and enter the
programming mode. With the arrows ◄ ► button scroll through the menu untill appears
ALARM.
With the arrow ▼ go into the REF. IMP that allows, through ◄ ► to set the number of
Sampling pulses (eg. 10).
By pressing the arrow ▼ again go into the menu MAX DIFF that allows , through ◄ ► to fix the
maximum number of admissible failures (eg. 5 each 10 impluses), besides these the pump
gives the allarms. Then press the ▼ or ▲ arrow to escape and the START button to
recommence dosing with the new settings. (Fig. E)
