Fig. 19: Diagram for flow Q as current signal
(here: 4 ... 20 mA)
Draw a diagram as above - with values
for (4 mA, Q1) and P2 (20 mA, Q2) or
(0 mA, Q1) and P2 (20 mA, Q2) - to be
able to output the flow Q of the Dulco‐
Flow
®
as required as a current signal.
The DulcoFlow
®
issues an error message in the
event that the limits specified here are
exceeded and the status LED (left) lights up
orange.
The damping of the flow values displayed can
also be changed (not with volume figures) if
they change too quickly / too slowly in the dis‐
play.
The higher the integration constant entered in
the
‘damping’ menu item, the greater the
damping of the flow values displayed.
A setting can be entered in the
‘error output’
menu to determine whether the DulcoFlow
®
outputs an error signal via the current output to
an external unit (23 / 3.6 mA).
If the
‘controlled pump’ menu is selected, the
DulcoFlow
®
with the control module of a
metering pump delta
®
can control the flow - see
the “Supplementary operating instructions for
the metering pump delta
®
- control module
delta
®
”.
Simulation
Go to the
‘simulation’ menu and set the
required current under
‘simulation’ to
simulate a current signal coming from
the DulcoFlow
®
for another unit.
ð
The DulcoFlow
®
generates this cur‐
rent while the
‘simulation’ menu
item is open.
The operating menu does not close
automatically while the ‘simulation’
menu item is open.
The DulcoFlow
®
can be used to aid
troubleshooting or commissioning of
different output signals – refer to the
"Installation" - "Main Menu Settings" -
"Counter Output Menu" or "Current
Output Menu" chapters.
