MP2SP-SPEEDY-PH Multi Peristaltic Dosing Pump
PROGRAMMATION Push and hold the SET button for 3 seconds, on the display the previously stored value will appear. Always by pushing the SET button you can select the setpoint value in a range between 6.0 and 8.0. once the value is selected, wait for 5 seconds without pushing any button and the value will be automatically stored.
Attention,
- The electrode calibration procedure can require some minutes, for a very accurate reading; it’s very important to follow the operation sequence indicated here below.
- Be sure that the buffer solution used in calibration always matches the indicated value, and that they’re not polluted.
Dip the probe in the pH7 buffer solution. Wait few seconds for the reading
stabilization.
Push the CAL button for 3 seconds, on
the display the 7.0 value will start blinking.
When the probe calibration is finished, the value on the display will become
fixed If at the end of calibration, the display will show the writing “rc”,
push the Cal button to exit and return to reading. Repeat the procedure, if
after the second try the writing “rc” will appear again, substitute the probe
because it is not working well.
FUNCTIONING AND VISUALIZATION
During the functioning, the value of the pH read will be visible on the
display. The functioning of the pump is proportional, with pause-work time.
The maximum proportionality value will be factory set to a value of pH 1,0.
Functioning examples: Setpoint 7,3
Reading value higher than 8,3, the pump works in continuous.
Reading value 7,8, the pump works for 75 seconds alternated to 75 pause
seconds. Reading value 7,3, the pump is stopped.
The minimal working time of the pump will be of 5 seconds.
DEFAULT SETTINGS
- SETPOINT: Set = 7.3 pH
- MAXIMUM PROPORTIONALITY: 1,0 pH
- PREARRANGEMENT FOR DOSING:
SULFURIC ACID H2SO4
Alarm function
The alarm function avoids the pump dosing when the chemical product is over,
or the overdosing for an eventual bad functioning of the probe.
If the measure does not reach the setpoint after about 1,8 litres of chemicals
dosing, the pump will go in Alarm mode. It will stop dosing; the display shows
the reading “AL” and the alarm led will blink.
It is possible to unlock this protection pushing the button SET for 3 seconds.
Verify anyway the level of product to dose before restarting the pump.
