8.4 - LEVEL CONTROL (UPON REQUEST)
If the dosing pump is supplied with level control setting and upon request floating level switch. When
the level of the additive is lower than the switch, level alarm goes ON, the display will show "FAO",
the pump is off giving an optical and sound alarm. The level control alarm goes ON with 5 seconds delay.

8.5 - CALIBRATION

Turning on the pump, the instrument switches automatically to the "METER" function.
Pressing button mA pulse (5) will show the actual mA input signal. To go back to strokes/min press again. The
manual function is also used when priming the pump. In order to avoid programming and setting errors during
the system functioning, the pump is programmed to automatically return to the Meter Mode each time the unit
is switched OFF.
8.6 - PARAMETERS SETTING MODE (Fig. 16)
• "Manual" Mode
Turn pump ON
A. On the control panel press button F (14) and start manual mode: ("Manual" LED 2 ON )
B. By means of button 10 (increase) and 3 (decrease), select the number of imp/min. To prime the pump set
pulse rate at 75%.
C. Prime the pump.
• "Set 1" Mode
Mode Set 1 is used to select the mA input value/min. dosing pump flow and pulse frequency.
A. Press button 14; Set 1, LED ON. The display will show the pulse frequency previously set.
B. Select the minimum pump output required pressing buttons 3 and 10. If the minimum output is zero set 000.
C. Press button 5 "mA" LED ON:
D. By pressing buttons 3 and 10, you can select the mA input value corresponding to minimum pump output
required. Confirm with enter 11. To finish the programming procedure and modify the maximum output
value, press button 14 which will automatically change to mode Set 2.
• "Set 2" Mode
Mode Set 2 selects the mA input value/max. dosing pump flow and pulse/frequency.
A. Press button 14 Set 2 LED ON, the display will show the frequency previously set.
B. Press buttons 3 and 10 to set the desired imp/frequency at the maximum pump output required.
C. Press button 5 "mA/pulse", the display will show the value previously set.
D. Pressing 3 and 10 select the mA input value at the maximum pump output required.
E. Press button 11 to enter. The pump will automatically return to "METER" mode and is operational according
to the selected functioning mode; two modes are available: direct/reverse.
• Direct Functioning Mode
During production the pumps are programmed for a 4-20 mA direct functioning curve. The pump will start
every time the mA signal goes above 4 mA increasing the pulse frequency (and consequently the flow) pro-
portionally to the mA input signal up to maximum imp/min frequency available. E.G. Set 1 minimum signal
4 mA, minimum output. Set 2 maximum signal 20 mA, maximum output.
• Reverse Functioning Mode
Reverse functioning is when the mA signal increases and pump output proportionally decreases. Select the
maximum mA signal required with mode Set 1 (in relation to the min. output).
E.G. Set 1 maximum signal 20 mA, minimum output.
Set 2 minimum signal 4 mA, maximum output.
