INTRODUCTION
This section explains the error indications and corrective
actions for the Configuration Port Module (IMCPM01).
ERROR INDICATIONS AND CORRECTIVE ACTION
The CTT01/02 receives power from module mounting unit. If
the CTT loses power, follow the steps in this section. There are
no active electrical components on the CPM. The only replace-
able part is the 0.5 Amp 250 Volt fuse.
MODULE REPLACEMENT
NOTE: You can remove the CPM module while system power is
supplied.
1. Remove the CTT cable from the connector in the CPM face-
plate.
NOTE: When removing the CTT cable pull on the plug, not on the
cable.
2. Lock the module by turning the two captive screws on face-
plate one-half turn. The module is unlocked when the notch on
each screw is vertical and the open end is pointing away from
the center of the module.
3. Gently slide the module out of the module mounting unit.
4. Test the fuse to see if it is open. If the fuse is open continue
with Step 5. If the fuse is good continue with Step 6.
5. If the fuse is open, remove it from the fuse holder (see Fig-
ure
). Install a new fuse, use only a 0.5 Amp, 250 Volt fuse
(Bailey Controls P/N 194776A15000).
6. Connect the CTT cable to the connector on the front of the
CPM. Check the cable to see that it is seated.
7. Insert the module into the module mounting unit. Refer to
for the procedures to install a module.
8. If the CTT does not power up, it needs to be checked. Refer
to the CTT Product Instruction for troubleshooting and repair
information.
NOTE: If the CPM is faulty, replace it with a new one.
