SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section explains how to detect IMFEC1
analog input
module errors and the corrective action to take for those
errors.
Status reports from the control module are available through
any INFI 90 OPEN operator interface such as an operator inter-
face station (OIS), configuration and tuning terminal (CTT) or
an IBM
®
AT compatible computer with the SmartLink transmit-
ter management software package.
From the module summary display on the operator interface,
call up the
I/O SLAVE
status report. The status report will dis-
play specific FEC module and smart transmitter error codes
when an error occurs. The status report lists the following:
I/O SLAVE ERROR NUMBER (#), SLAVE ADDRESS (#),
BLOCK NUM. (#)
NOTE: The instruction for your particular operator interface will
explain how to access the module summary display.
MODULE STATUS REPORTS
To determine if the error number belongs to the IMFEC1
module, check the function block to find the function code
assigned to the block. If the block is function code 132, then
the status report refers to the FEC module. Table
lists the
meaning of FEC status report error codes and corrective
actions.

No.
Description
Corrective Action
1
No IMFEC1
mod-
ule response or
wrong module type
Check IMFEC12 switch setting. Check
IMFEC11 jumper and switch settings.
Replace the FEC module if switch and/or
jumper settings check good.
Check function code 132 for correct specifica-
tion values, such as I/O module address.
2
Calibration error
Replace the module.
3
Channel failure or
out of range
Check TU or TM and cabling. Replace
IMFEC1
module if cabling is good.
Check function code 132 for correct specifica-
tion values, such as I/O module address.
