6.2.2. Backwash pump
In the case of the “Backwash pump” all that has to be
entered, in the inventory, is the relay output it is connected to.
A security switch can be activated. This can be linked to one
if the available inputs, and it can be set if the switch is
“normally closed” or “normally opened”.
An analogue output can furthermore be selected with which,
for example, a frequency regulator can be set.
For more information, see § 5.1 “Inventory” on page 12.
It can be indicated if the backwash pump is dependent on the level in the permeate tank.
If it depends on the level in the permeate tank, then the backwash pump will be turned off if the
permeate tank is empty.
6.2.3. Dosing pumps
In the case of the “Dosing pump” all that has to be entered, in
the inventory, is the relay output it is connected to.
A security switch can be activated. This can be linked to one
if the available inputs, and it can be set if the switch is
“normally closed” or “normally opened”.
For more information, see § 5.1 “Inventory” on page 12.
The subsequent programming of the dosing pump allows a dosing time to be set between
0 and 9999 (seconds or minutes). When a dosing time of 0 is entered the dosing pump is switched on
until the end of the phase.
The controls of the dosing pump (“Output”)
can be adjusted and connected to a dosing
tank in the programming of the dosing pump.
The dosing pump can be switched on with a
delay, after the start of the phase. A delay of
0 to 9999 seconds can be entered.
