Task:
The pump is to meter 2 litres every half hour every weekday
(Mon-Fri) between 8:00 and 11:00.
Solution:
As you define switching times with the timer, you need to first
define the switching points at 08:30, 09:30 and 10:30.
To meter 2 litres, the pump needs to work in
‘Manual’
‘Mode’
for
10 min at a
‘Dos. capacity’
of 12,000 l/h. A
‘Dos. capacity’
of
12,000 l/h is thereby added to the switching points.
You also need to define the switching times to stop the pump at
08:40, 09:40 and 10:40 - paired with the
‘Halt’
action.
