There are also other Safety Function Status codes can also cause the
outputs to go to a safe state. These errors are not latchable and the AO
current is fixed.
Safety Shutdown Reason Codes
This Safety Function selection is available on all three outputs. When
selected, the output is not functional. For the analog output, the output current
becomes fixed at 21 mA.
The analog output is not functional, and the output current is fixed at 0 mA.
These are not errors but are considered to be uncertain conditions,
since the requested current level cannot be produced.
Safety Shutdown Reason Codes
An analog output current level above 20.5 mA is being requested. The actual
current level stays at the upper limit of 20.5 mA and the SIL function health
status becomes Uncertain.
An analog output current level below 3.8 mA is requested. The actual current
level stays at the lower limit of 3.8 mA and the SIL function health status
becomes Uncertain.
The Upper Range Value and Lower Range Value are equal, preventing a
product level percent of range from being calculated. The output current stays
at the upper limit of 20.5 mA and the SIL function health status becomes
Uncertain.
The analog output has not been calibrated. The output current which
corresponds to the product level may not be accurate.
