6.6 System choice

Define the system size and the operation mode in the "System
choice" menu.
The input can be cancelled at any time using the [Escape] key.
The activated system type or the activated mode is displayed
flashing on the display.
6.6.1 System type
• Scroll in the main menu using the [ARROW RIGHT] key on
page 2.
• Use the [F1] key to switch to the "System choice" menu.
• In the "System choice" menu, switch to the "System type"
menu using the [F1] key.
• Select the system size using the [F1], [F2] or [F3] keys, scroll if
necessary using the [ARROW RIGHT] or [ARROW LEFT] key.
After selection of the system type, the following message is
displayed:
System type
164-XXXXD
activated
• Use the [Enter] or [Escape] key to return to the "System
choice" menu.
The system is preset in the factory. The selected type
of system is displayed flashing in the "System
choice" menu.
Note
Check this setting for correctness prior to starting up,
or select a new system type.
6.6.2 Operation modes
5 different operation modes can be selected:
• Batch mode
The performance of the system (100 %) is controlled by the
use of a buffer tank.
• Current input
The system performance (2.5-100 %) is controlled via an
external current input signal, e. g. 4-20 mA.
• Contact input
The system performance (2.5-100 %) is controlled via an
external contact input signal, e. g. from a contact water meter.
Set the contact water meter in such a way that, at
max. performance the control contacts are not < 1
contact/sec.
Note
If, in exceptional cases, this value is < 1, min. 0.25
contacts/sec., the bypass "Min" time must be
increased.
The controller can process a maximum of
47 contacts/sec. If a value greater than
Note
47 contacts/sec. is calculated, use a different contact
water meter.

• Manual control
The system performance (0-100 %) is controlled by manual
input.
When "Manual control" is selected, the installation
can only be started in "Manual mode". If the
Note
installation is started in "Automatic mode", an alarm
message is displayed, and the system stops.

0.3 ppm x 30 m³/h = 9 g/h
1 contact/litre x 30 m³/h x
1000/3600 = 8.33 contact/sec.
• Target value external
The system performance (2.5-100 %) is controlled via a Bus
system (can only be selected, if a bus system has been
selected in the "Basic settings > Bus" menu).
The mode is factory-set, i.e. the selected mode is
displayed flashing in the "Operation mode" menu.
Note
Check that this mode is correct before
commissioning; if necessary, select a new mode.
The entry of the parameters for current input and
contact input is described in the Section on
Note
"Commissioning".

6.7 Units

Either metric or US units of measurement can be selected on the
system:

6.8 Setup

In the main menu, switch to the "Basic setting" menu using the
[F2] key (scroll if necessary).
6.8.1 Language
• In the "Basic setting" menu, switch to the "Language" menu

6.8.2 Min. contact water
The min. contact in the main water line (on site) switches the
system to standby, if the set minimum main water flow is fallen
below.
• In the "Basic setting" menu, select the "Min. contact water"
menu using the [F2] key.
• Activate or deactivate the function using the [F1] or [F2] key.
Min. contact main water

• Press the [F1] key to select the variable input fields.
Switching between the values (0 %; XX mA; 100 %; YY mA) is
also carried out using the [F1] key.
• Enter individual values using the [UP] and [DOWN] keys
(modify numerical values) and the [ARROW LEFT] and
[ARROW RIGHT] keys (change input position).
• Confirm the set values using the [Enter] key. The selected
