Operation Of The System; Automatic Operation - Grundfos Oxiperm OCD-164 Montage- Und Betriebsanleitung

8. Operation of the system

Before the system is started, the system size and
Note
operation mode must be selected.
Independent from the operation mode, the menu structure
remains the same, the only difference is in the display of the
prevailing signals, i.e. current input in mA, contact input in 1/s and
manual mode in %.

8.1 Automatic operation

In "Manual control" mode, automatic operation is
Note
impossible.
8.1.1 Current input/contact input
• In the main menu, switch to the "Automatic > start" menu using
the [F1] key.
Auto: x.x/y.y

Depending on the mode setting, the x.x/y.y field indicates the
prevailing current signal in mA or the prevailing contacts
(contact water meter) in 1/s.
• Activate or deactivate the system using the [Enter] key.
The display changes from "start?" to "active" or from "active"
to "start?". The display shows the most important information
about the operation of the system. Further information, such
as levels, dosing pumps and bypass water, can be obtained by
scrolling with the arrow keys to the pages 2 and 3.

The Hall sensor signals and the signals from the flow
controllers can be checked in this menu.
The values displayed here are not identical to the
dosing stroke details from the individual dosing
Note
pumps, e.g. 120 strokes/min, because the calculation
does not relate to 1 minute.
The default value changes as the installation runtime
progresses, whereby the following evaluation is decisive.
H = X: Hall sensor signals
D = X: flow controller signals.
Each of the Hall sensor signals from the dosing
D = H
pump is fed back by the flow controller.
More flow controller signals are fed back, i.e. if the
deviation is too large, this reduces the precision of
D > H
the flow monitor, although the system keeps running
(there is no error message).
Too few dosing controller signals are fed back, the
D < H system goes into malfunction mode. The dosing
controller settings have to be checked.
The installation is correctly set at D = H whereby a
few extra dosing controller signals (D > H) have no
Note
bearing on the precision of the system.
• Use the [Escape] key to return.
Bypass water
• Use the [F2] key to switch to the "Bypass water" menu.

The target and actual value for the bypass water can be
checked in this menu. The limits can also be changed in this
menu.
Changing the limit
• Use the [F1] key to switch to the input field -XX or +600 %
• Enter the value by pressing the [UP] or [DOWN] keys (to
change the number), and the [LEFT] and [RIGHT] arrow keys
(to change the input position).
• Switching from -XX to +600 or from +600 to -XX is carried out
using the [F1] key.
• Press the [Enter] key to confirm the entry.
• Use the [Escape] key to return.
If a new system size is set, the preset limits for the
