Display of pressure and temperatures
One to four separate displays can be connected to the controller.
Connection is accomplished by means of wires with plug
connections. The display may be placed in a control box front, for
example.
When a display is connected, it will show the value for what is indi-
cated in the setup. It can be
- P0
- Sctrl
- Ss
- Sd
- Pd
- S7
- P0 bar
- Pd bar

* The primary reading can be changed to other measurements, if required.
When a display with control buttons is chosen, a simple operation
via a menu system can be performed in addition to the display of
pressure and temperatures.

Initiation. Display is connected to output A. (- - 2 = output B, etc.)
If you want to see one of the values for what is given under "func-
tion" you should use the buttons in the following way:
1. Press on the upper button until a parameter is shown
2. Press on the upper or lower button and find the parameter you
want to read
3. Press on the middle button until the value of the parameter is
displayed.
After a short time, the display will return automatically to the
"Read out display".
