A-67
RIO: Short-circuit
Description:
There is a short circuit between two field terminals or cables.
Possible
consequences:
The device connected to the actual channel might not operate as intended. If
signal is input, value is frozen to last valid input as long as alarm is active.
Corrective
actions:
Check physical loop/cabling.
RIO: Test channel error
Description:
Error on one of the RIO module internal test channels.
Possible
consequences:
The RIO module is not able to complete all self test routines.
Corrective
actions:
Replace RIO module
RIO: Too low feedback while PDU=1
Description:
Second barrier (PDU) does not seem to work.
Possible
consequences:
Second barrier may not be able to ensure shutdown. NB: Overrides all other loop
monitoring results.
Corrective
actions:
Replace RIO module.
RIO: Too slow signal transition
Description:
A digital signal has used too long time in transition between states.
Possible
consequences:
The device connected to the actual channel might not operate as intended. Input
value is frozen to last valid input as long as alarm is active.
Corrective
actions:
Replace RIO module.
RIO: Voltage feedback outside tolerance
Description:
The return signal from an analog output voltage signal is outside expected limits.
Possible
consequences:
The device being controlled by the actual output signal might not operate as
intended.
Corrective
Check the physical loop/cabling.
