TD 8250 programming
Each time the TD 8250 is to be operated, it is necessary to adapt the unit to the connected
flow sensor.
Input procedure:
The input procedure is the same for all input values and is therefore described once only.
Programming is carried out by two keys which are accessible after removing the front panel.
For this purpose, the two round plastic caps are removed by a small screwdriver in order to
get to the underlying mounting screws for the front panel.
The positions of these two keys is shown below.
Start input operation:
“T1“
and „
T2
“ are depressed for approx. four seconds to start the input operation.
The first two segments are switched dark, segments three and four display the menu refer-
ence number
”00“
. Release
“T1“
and „
T2
“.
Change menu reference:
By briefly pressing
“T1“
the menu reference numbers
“00” to “10”
can be displayed in se-
quence.
An input value is concealed behind each menu reference number.
To display the input value, press
“T2”
briefly. A four digit input value appears.
Change input value:
The point marks the digit which can be changed by actuating
“T2”
.
The point can be moved by actuating
“T1“.
After setting the numerical values the point must be placed at the correct position.
On actuating
“T1”
and
“T2”
, the display reverts to the menu-reference level. The menu ref-
erence
“00”
is displayed again.
Stop input value:
To exit the input operation, depress
“T1”
and
“T2”
again for approx. four seconds.
