PROGRAMMING AND VISUALIZATION OF PROPORTIONAL FUNCTIONING IN Rx (mV) TYPE
During the programming if you do not push any button (+,-, CAL) for more than 60 seconds, the pump will
get out of programming keeping the data stored until that moment.
Rx (mV) PROBE CALIBRATION
Attention,
Be sure that the buffer solution used in calibration matches always the indicated value, and that they're not polluted.
BUFFER 468mV
Rev 1.0
Range of proportionality = 100mV
Time base: 300 sec
Push and quickly release CAL button and scroll the menu using + and – buttons
till the display shows "Function Type". Push CAL to enter the submenu and
then, by pressing + and – button, choice "Function Prop" and confirm pressing
CAL.
The display will show the value of setpoint stored in the last programming. Modify
it by pressing + and – button and confirm the choice pressing CAL.
The display will show the direction of dosing Oxid or Red stored in the last
programming. Choice the direction by + or – button and confirm pressing CAL.
Select Red if you want the pump to inject for mV values greater than Setpoint.
Select Oxid if you want the pump to inject for values of mV lower than Setpoint.
The display will show the value of "Delay On" stored in the last programming.
This is the seconds of delay of motor's start up when the measure will overtake
the setpoint. Modify it by pressing + and – button and confirm the choice pressing
CAL.
Push ESC button to esc the menu and go back in measure with the Proportional
functioning just programmed.
In the Proportional functioning the display shows on the first row "Prop" and the
actual % flow rate of dosing. The % flow rate is calculated according to the
measure sampled at the beginning of the dosing cycle.
On the second row the display writes the measure.
Cod. 00.008.646
OFFSET CALIBRATION
Dip the probe in the 468mV buffer
solution and wait for the stabilization of
the measure on the display. Push and
quickly release CAL button and then
scroll the menu till the display shows
"Electro. Calibr." Push CAL to enter
the submenu and then the button – to
do the OFFSET calibration of the
probe. If it is necessary you can modify
the value of the buffer solution shown in
the second row of the display by
buttons + or -. Push CAL to confirm.
If the display shows the message
"Imposs. Calibr." the probe calibration is
not saved. Read
paragraph named "MESSAGES FROM
THE PUMP". If no error message
appears the calibration has been
performed.
