Troubleshooting and Repair
5.1
INTRODUCTION
This section describes the maintenance testing, troubleshooting, and repair
procedures for ICS's Model 8099 Ethernet to Digital Interface.
5.2
MAINTENANCE
The 8099 does not require periodic calibration and has no internal adjust-
ments.
5.3
TROUBLESHOOTING
Troubleshooting is broken down into selftest errors and operating errors.
5.3.1 Self Test Errors
Self Test errors occur at power turn-on time. The 8099 indicates self- test er-
rors by blinking one or more of its LEDs at a 2 Hz rate. Refer to paragraph
5.4 for more information about the Self-Test Errors. The Self Test error codes
and their most likely causes are listed in Table 5-1
5.3.2 Operating Failures
Operating failures are those failures that occur while using a unit that has passed
its power turn-on self test. Use the fault isolation information in Table 5-1 to
narrow the problem down to a specific area. The majority of installation hookup
faults can be fixed by following the table and making the necessary corrections
to the installation wiring or to the application program.
