5.2.4 Set FlowDrive configuration
The FlowDrive can work in two drive modes;
FlowDrive mode and generic drive mode.
In FlowDrive mode the drive is configured for reservoir level
control and in generic drive mode it behaves just like a nor-
mal Emotron FDU drive.
By default the drive is configured in FlowDrive mode and
the remaining quick start guide describes configuring this
mode. In case you are interested in running the FlowDrive
as a normal drive change parameter “[21C] Drive appl.” to
“Generic” and consult the software instruction manual.
In FlowDrive mode the drive can operate as a Standalone
unit (1 drive) or in a Master-Follower configuration (2
drives).
The following configurations should be done on all drives
independent of drive mode (Standalone, Master, or Fol-
lower).
1. Press toggle button once more or navigate to menu
“[3A11] FLD Config“
Select whether the FlowDrive should be controlled as a
- ‘Standalone’, Configuration for a single drive/pump in
pump sump.
- ‘Master’ Configuration for the main drive in a dual
drive/pump setup
- ‘Follower’ Configuration for the secondary drive in a
dual drive/pump setup.
2. Press toggle button again or navigate to menu
“ [341] Min frequency”
Minimum frequency is by default set to 70% of nominal
motor frequency. I.e. 35Hz in case nominal motor
frequency is 50Hz. In most cases this is low enough to be
able to find the best efficiency point and high enough to
ensure that the pump generates a sufficient flow. Adjust
upwards if the default value is considered to be too low
for keeping up with normal inflow.
For units configured as “Follower” in menu [3A11] this con-
cludes the configuration. For other units continue with the
next section.

Additional configuration
for Standalone / Master
drives
5.3.1 Level sensor configuration
The level sensor connected to the standalone or master unit
needs to be configured based on its type and placement.
Navigate to menu [3C13] or press the toggle button.
1. “[3C13] Sensor min”
This is configuration of which level, in meters, the min
analogue signal from the sensor should represent. Gener-
ally this is 0 for a pressure sensor placed in the bottom of
the sump. Press
to continue.
2. “[3C14] Sensor max”
This is configuration of which level, in meters, the max
analogue signal from the sensor represents
.
This data is
dependent on the sensor but often sensors with a range
of 5 or 10 meters is used.
Regarding more advanced functions please refer to the
Software instruction manual
5.3.2 Set sump levels
Set the desired levels for actions to be taken (starting and
stopping of the pumps), see Fig. 50, page 42.
Navigate to menu [3A21] or press the toggle button again
and set following.
1. “[3A21]Overflow “ Level where the overflow alarm is
triggered. Press
to continue.
2. “[3A23] Start level” Level where the pump is started,
Press
to continue.
3. “[3A25] Stop level” Level where the pump is stopped
Press
to continue.
Note: Overflow level has to be higher than Start level
which has to be higher than Stop level.
