INTRODUCTION
This section describes the maintenance, troubleshooting and repair procedures
for the 4807/2307/4867/2367 Data Acquisition and Control Boards and
Modules. All comments and errors apply equally to all units unless
otherwise stated.
5.2
MAINTENANCE
The units contain analog devices and do require periodic calibration. At this
time, a calibration period has not been determined. Contact ICS for
calibration directions.
5.3
TROUBLESHOOTING
Troubleshooting is broken down into self test error and those that are occur
during usage.
5.3.1
Self Test Errors
Selftest errors occur at power turn-on time. The cards indicate self test errors
by blinking one or more of their LEDs at a 2 cps rate. Verify the error by
turning the unit off for 10 seconds. Disconnect the unit from any other
equipment and then turn the power back on. If the error persists, it is a true
self test error. The self test error codes and their most likely causes are listed
in Table 5-1.
