The specific setting parameters for your system
depend on the circumstances of your plant installa‐
tion. Here we give general guidelines. The setting
parameters for your specific system may differ
from these.
Dependent on the function and hygiene parameters you can con‐
trol a frequency-driven circulating pump and set each desired cir‐
culating rate using a 0 ... 20 mA signal or a 4 ... 20 mA signal.
Simultaneously you can also adjust the circulating rate to match
the particular hygiene situation in the swimming pool
The analogue outputs for line 1 and/or line 2 are to be connected
to terminal
[K1] and [K2] . The respective individual settings of the
minimum and maximum values must be made at the Dulcomarin
®
II in the configuration
[F3] . The adjustment values are selected
using the
[UP] and [DOWN] keys. Access the Entry field by
pressing the
[ENTER] key.
Initial situation: You are in the Dulcomarin
®
II in configuration
[F3]:
1.
First set the start point for
[0 mA] or [4 mA] .
ð
In most cases the start point is 0 m
3
/h.
2.
Set the maximum circulating rate for the pump.
ð
This specifies the maximum possible circulating rate
value, that can appear on the display.
3.
Set the
[Filtration speed] in normal operation
The filtration speed is calculated from the flow rate/filter sur‐
face
ð
For private applications set a filtration speed of up to 50
m/h, for public applications up to 30 m/h
4.
Enter the
[Backwash speed] . In most cases this is greater
than the filtration speed.
Backwash speeds of up to 60 m/h are possible. Here you can
set the optimum backwash speed in manual mode. Increase
the backwash speed until the filter sand is lifted and conse‐
quently cleaned; however do not set it so high that sand is
washed out of the system.
5.
Under menu option
[EcoMod speed] enter the permissible fil‐
tration speed. Here, a very low filtration speed can be set for
private pools, however in the public area, the specifications
of DIN 19643:2011-05 must be observed. The overall length
of the overflow gutter is definitive for setting the filtration
speed. Continuous flooding of the overflow gutter must be
ensured
DIN Error
If [DIN Error] is set to [active] , the circulation is
immediately increased to the maximum value if the
set limit values are exceeded. If [DIN Error] is set
to [inactive] , then, dependent on the setting, the
circulation is steadily, but not immediately,
changed over to [Normal mode] .
Setting: Circulation 0/4 ... 20 mA
