44
430
Device changed
(different type)
Option board changed for one not present in the
same slot before. No parameter settings are
saved.
Reet the option board parameters.
45
440
Device changed
(different type)
Option board added. The option board was not
previously present in the same slot. No parameter
settings are saved.
Reset the option board parameters.
50
1050 AI Low Fault
One or more of the available analog input signals
is below 50% of the minimum signal range.
A control cable is defective or loose.
