1) 3)
A fault has occurred in the setting of a
parameter:
wire fracture
connection design of the sensor
sensor type and temperature range.
·
Check the parametrizing
undertaken and, if necessary,
undertake the parametrizing again
with the correct parameters (valid
parameters see section 4.4.3).
The analogue input module will be
operated further with the last valid
parametrizing.
1)
The analogue input signals will, however, be processed further.
2)
Processing of the analogue input signals will be stopped. This error message will be triggered by
the field bus node.
3)
The parameters entered will be ignored, the module operates with the last valid parameters.
