•
LED Sensor Error
The LED sensor error indicates a failure at a sensor and the sensor-LED blinks. The sensor alarm relay
K7 has switched. Refer to operation mode 5. Also see analog output.
•
Display

sensor interruption or over-range
-EE
sensor short circuit or under
–range
•
Analog output 0 mA/0 V
If sensor failure short circuit or sensor interruption is detected the output current is 0 mA and the output
voltage 0 V.
