are displayed for the C.O. module, perform the
following actions:
6WHS
Make sure there is a C.O. Interface Cable and a catheter connected to the module. If
not, connect them.
6WHS
Make sure the C.O. parameter is turned on. Turn it on, if it is not.
6WHS
Make sure the C.O. numeric is turned on. Turn it on, if it is not.
6WHS
Make sure you don’t have more than one C.O. module plugged into the module
racks you are using. If more than one C.O. module is plugged in, the supernumerary
modules are ignored and should be removed.
6WHS
Check the connection on the module and the rack interface.
Unplug and re-plug the C.O. module and check if the green LED on the C.O.
module lights up after re-plugging. If it does not, proceed with the following:
Put the C.O. module into another slot and check the LED once again. If it lights
up now, the connector for the previous slot is faulty and the rack needs to be
replaced. If it does not, proceed with the following:

Replace the cable from the Satellite Rack to the function box. Again unplug
and re-plug the CO
module and check if the LED lights up. If it does not,
proceed with the following:
Plug any other (not faulty) module into the same slot and check if the LED
lights up. If the LED of the alternative module lights up, the C.O. module is
defect and has to be replaced. If it does not, either the rack or the rack interface
card is defect. Proceed with the following:
Replace the rack and plug in the C.O. module into the new rack. If the LED on
the module does not light up, replace the rack interface card in the function
box.
