SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section explains the error indications and corrective
actions for the Analog Slave Output (ASO) module.
ERROR INDICATIONS AND CORRECTIVE ACTION
You can obtain the status of the ASO through an INFI 90 oper-
ator interface (e.g., Operator Interface Station, Engineering
Work Station, Configuration and Tuning Terminal) or the front
panel module status LED indicator.
Status LED
The front panel status LED has three states to indicate normal
operation and error conditions. Table
5-1
lists ASO status LED
states, error indications, probable causes and corrective
actions.
NOTE:
If the corrective actions in Table
5-1
do not correct a problem
with the ASO module, replace it.
Master Module Errors
The Multi-Function Processor (MFP) performs status checks on
the ASO. An error will appear in the report function of an oper-
ator interface. Refer to the Product Instruction for the operator
interface you are using for an explanation of these reports.
Function Code (FC) 149 output block N+7 in the MFP configu-
ration is the ASO status flag (logic 0=good; logic 1=bad). You
can use an operator interface to monitor this block. If the sta-
tus flag is a logic 1, check the front panel module status LED
and the operator interface report function to determine correc-
tive actions.
NOTE: If FC 149 specification 3 is set to 0, the MFP will trip when
the ASO module fails. Changing specification 3 to a 1 allows the
MFP to continue to operate if any ASO error condition exists.
