Automatic sensor control
Manual switch-on and switch-off of the cold cathode can be done by software com-
mand “Cathode Control” (CC) or by applying a defined voltage signal to pin 9 of the
transmitter’s electrical connector. As voltage level 3 … 24 VDC (default) or alternatively
GND can be used, the selection is done by the parameter “Cathode Control Logic” (DL).
Cathode Control Logic (DL):
The cold cathode sensor can be switched on or off by applying a defined voltage signal
to pin 9 of the transmitter’s electrical connector (see chapter
I/O and Communication
Port Schematic [ ► 9]
).
By means of the parameter “Cathode Control Logic” (DL) you can select via software
command, if a 24 VDC or GND level signal shall be used.
Settings Meaning
0 GND
1 (Default) 3 … 24 VDC
The cold cathode sensor will be active as long as the voltage signal is applied.
The parameter “Cathode Control Logic” (DL) can also be queried.
