9 Operating/configuring the OTT netDL unit on site
For operating the unit on site, OTT netDL is equipped with a backlighted LCD display
(4 rows x 20characters) and a "jog shuttle". The jog shuttle is a special operating
button that can be rotated and pressed.
The following functions can be called with the jog shuttle:
Determine and display instantaneous values (Observer function)
– with input of a check value (manual value),
– without input of a check value (manual value).
Enter observer texts
(extended Observer function)
Scale instantaneous values/stored values
(set offset)
Display/set date and time
Enter manual values into a manual sensor
Display information on transmissions
Display information on connections
Display system information
Start voice announcer (optional)

9.1 Detecting and displaying instantaneous values
(Observer function)
Requirements
The configuration of a channel that is to determine and display an instanta-
neous value must include the "Instantaneous value" function block (refer to
online help).
If additional check values are to be entered, the "Observer manual input"
option in the "Instantaneous value" (OTT netDL Firmware 2.11.0 and earlier:
"Display/Observer" function block) function block must be activated (refer to
online help).
How to determine and display instantaneous values without
entering a check value (manual value):
Press jog shuttle twice. (Between the first and second presses, the
LCD display
shows the OTT netDL firmware version.)
The OTT netDL unit activates the
LCD
display
and shows the selection menu (if password protection for the LCD
display is active ➝ enter the four-digit password first; refer to online help).
Press jog shuttle (Observer). The
LCD display
shows the station name, the sta-
tion number, the current time and, after 2 seconds, the level of the voltage supply.
Press jog shuttle (¥). The
LCD display
shows the screw terminal strip used, the
sensor name/number and the instantaneous value of the first channel (sensor).
To show the instantaneous values of additional channels, press jog shuttle once
each time (¥). After the instantaneous value of the last channel has been
shown, the LCD display shows the instantaneous value of the first channel
again.
To end the display of the instantaneous values, rotate jog shuttle to ≈ and press
(max. twice); then rotate jog shuttle to
End and press. If the jog shuttle is not
used for three minutes, the LCD display shuts off automatically.
