Chapter 6 Troubleshooting and Rectifying Channel/Field Faults
Installation
1. Examine the coding pegs on the termination assembly and make sure
that they fit the sockets on the rear of the new I/O module.
2. Place the I/O module on to the dowel pins on the T9300 I/O base unit.
Make sure the slot on the head of the module clamp screw is vertical and
then push the module home until the module connectors are fully mated
with the I/O base unit and termination assembly connectors.
3. The locking screw requires a quarter turn clockwise to lock. Use a broad
(9mm) flat blade screwdriver to lock the clamp screw. The locking screw
acts as a power interlock device and must be in the locked position when
power is applied otherwise the module will not be configured.
I/O Module Start-up
Process
The start-up sequence is different when a module is installed into an on-line
system that is running compared to installing the module into a system that is
off-line and has processor modules but no I/O modules installed.
