TIME ALARM
WHAT IS IT? The Time alarm
is expressed in units (0-120unit) of dosage.
One unit is equivalent to 150 injections of chemical. The injections counting
starts from 0 when the pump starts dosing after the power on, increases
during dosing, stops during level alarm and stand_by state, and is resetted
when the power is off, when the measure reaches the setpoint and during the
flow alarm. When the counting reaches the value memorized in Time alarm
the pump goes in Time Alarm state:
1) The dosing stops (no tension to the electromagnet)
2) Green led On blinks
3) the display shows
:“Tal”
and the % flowrate on the first row and the
measure on the second row.
Push and hold
ESC
button for 2 seconds
to esc the Time Alarm state and to
go back to functioning. The time alarm counting restart from 0 when the pump
starts dosing again

LEVEL CONTROL
The closing of the level input contact, free of tension, while the pump is working, will cause:
1) the dosing stops
2) the green ON led blinks
3)
the display shows “
Level
” alternatively on the first row and the actual measure on the second
row.
When the level contact gets opened again, the pump returns to working mode compatible with
the actual inputs. NOTE: The level alarm suspends (but not reset) the counting of the Alarm
Time
FLOW CONTROL
The closing of the flow input contact, free of tension, will cause:
1) the dosing stops
2) the green ON led blinks
3) The display shows “Flow” alternatively on the first row and the actual measure on the second
row.
When the flow contact gets opened again, the pump returns to working mode compatible with the
actual inputs. NOTE: The flow alarm resets the counting of the Alarm Time.
