Here you can invert the status function of LED for a contact: the LED is illuminated if the contact is opened, thus
falls below the minimum temperature, and when the LED is illuminated the status „error“ is indicated. Especially
the recording of incidents depends on the illumination of LED (see chapter 4.9
Diagnostics
, ).
The following menu items are available:
LED = output;
the LED is illuminated if the PNP
switching output is closed.
LED = -output;
the LED is illuminated if the PNP
output is opened.
Please note:
The recording of incidents specifically depends on the illumination of the LED (see
chapter 4.9
Diagnosis
, ).
