Sensor Alarm ON / OFF
Function only in controller mode (
2.01
)!
For
“
E1 Analog In
”
and if activated for sensor 2
“
E2 Analog In
”
.
In case of an interruption or short-circuit in the sensor conductor, or in case of measured values that
lie outside of the device
’
s measurement range, a time-delayed fault indication takes place.
