seconds.
Using the password 8599 gives the possibility to change the membrane flush time. These may
not be altered by others than authorized personnel from ML System a/s. If ML System a/s
detects that the flush time has been altered all guarantee for the membrane will become void.
The control panel
The control system consists of a Siemens PLC 200-S7 and a control panel Siemens TD200.
The control panel is used to show actual values and to change the various parameters used in
the calculations of the control system.
The display shows the messages in two lines. If there are more than two messages, a flashing
arrow - up or down - will mark that there are more messages. By pressing the arrow keys up /
down you can scroll through the messages.
If you want to change a value, the cursor is placed on the desired line and you press enter. If
the value is protected by a password, the display asks for password, and the values are
changed by using the key arrows till you reach the desired value, and then press enter.
When the password is entered, the control system shows the actual value, and you can change
with the key arrows up/down. When the desired value is reached, press enter, and the desired
value will be entered in the control system.
The display is constructed with four F-keys which combined with the SHIFT key make eight
areas for output and changes of values. The keys F4 and F8 are only used as reset keys.
The functions in F1-F2-F3 are reached by pressing the key directly. The F5-F6-F7 are
reached by pressing SHIFT - now a flashing “S” appears in the lowest right corner. Now you
can press the actual F key.
The display is in standard mode when none of the F-keys have been chosen. You press an F-
key for example to read or change values.
You return by pressing alarm reset or another F-key.
Anyhow the display returns to standard mode after five minutes.
