Handling without a PC
In the normal way front panel push buttons can be used to adjust set points read on the
digital display. Set points are secured against unintentional adjustments (jumper X5 2–
7). Enable push button adjustments by setting jumper X5 to 1–8.
In order to activate the UP/DOWN push buttons both SET buttons must be pressed
simultaneously. The display will start to flash. Set points can now be raised using > or
lowered using < push buttons. Keep the push button down to accelerate.
Use the STEP button to save the new setting. The new value will not be accepted until
STEP is pressed and the next value is displayed. If you want to restore the previous
setting and erase the new one you can do so by pressing both > and < simultaneously
(ESC) prior to pressing the STEP button.
The status line indicated which value is being displayed at present e. g.
•
E01 = input 1
•
T01 = temp. 1
•
F01 = flow 1
•
L01 = low alarm 1,
•
H01 = high alarm 1
Front push buttons can be disabled via an internal jumper (see section "Functional test
– Generals").
In that case measured values and trip setting can be displayed online, but alterations will
not be possible. The basic device function is outlined on the TAG covering the
microprocessor. You can replace the label yourself after changing the factory setting.
Carefully use your thumb and digit finger to lever the cover off the socket. The position
of the TAG can be taken from the device layout drawing in section "Layout".

The disk contains a print program TYPENG.TXT with some examples. These can be
altered using the EDITOR. Use the PRINT command in your DOS operating system
to print the label in IBM compatible printers. Proceed as follows:
Call the EDITOR in the main MENU using key <F2>. Select file TYPENG.TXT using
the tabulator key <TAB> and the arrow keys. Activate the file using <ENTER>.
Make sure only to overwrite lines in this file. Do not alter the line length. Do not go
beyond the markers. Do not enter new lines.
•
After saving file TYPENG.TXT using <ESC> leave the menu and return to the
DOS operating system pressing keys <ALT><X>.
•
Now enter the command PRINT TYPENG.TXT. Your IBM compatible printer will
now print a label of just the right size.
