ULTRA-CUT 100 XT/200 XT/300 XT/400 XT
Manual 0-5302 APPENDIX A-87
If at least one transmitter blinks plug the fiber back into that one then at the Gas Control end of the fiber (unplugged) you
should see the red light coming out of the blue end.
The Gas Control transmitter does not transmit except in response to a request from the CCM so you will not see any light
from the GCM transmitter with the cable unplugged. However, if you turn the connector 90 deg and insert the blue end into
the receiver (black housing), leaving transmitter open, then the GCM should receive the requests from the CCM and should
blink it’s transmitter (gray housing) in response. If not, problem is likely on the GCM board assuming it has power.
It is still possible even though you see the red light coming out the GCM end of the fiber that dirt in the transmitter or receiver
or on the fiber ends or the fiber is damaged so the light even though visible is not strong enough for the GCM board. If all
else fails replace the fiber cable and both CCM and GCM PCB.
502 CANBUS off due to excessive errors.
See 501 code for troubleshooting CANBUS faults.
503 CANBUS Data Error Warning.
This is a warning, does not shut the system down but is an indication that it probably will shut down soon (502 code).
Troubleshooting is same as for 501.
504 Reserved for future use.
Should not get this but if it happens may be due to EMI. Contact customer service.
Group 6 codes relate to the CCM and program updates. One exception is 619 which is a coolant flow
switch FS1 fault.
601-611 Various CCM CPU board internal faults.
For most of these faults try recycling the power but if the problem returns only thing to do is replace the CCM. Exceptions are:
1. 603 This is one of the reserved codes from the earlier product. Not used so it should never appear, if it does contact
customer service.
2. 607 Processor over temperature could occur if the ambient in the area of the CCM is too high. Try opening the upper
right side panel, perhaps blow some air to cool it off. If that doesn’t help or the ambient was not too hot to begin with,
replace the CCM.
3. 611 Code has various causes most of which require replacing the CCM. However, one possible cause is the programming
jumper on the CPU board (under the Static suppression PCB) has been left in the PROG position. This is a factory set-
ting used during initial programming and should never be found in the field. It is NOT used for application code updates
However, if someone did move it 611 will be the result.
612 USB port power fault.
USB port supplies +5V to power some USB devices such as the flash drive (thumb drive, memory stick), used for program
updates. A flash drive is the only device currently being used with this USB port. This fault detected no or low voltage to
the port. This could be a shorted flash drive or some other device that draws too much current exceeding the limits of the
USB power supply.
Try another flash drive or if you know this one is OK (it works with a computer), then replace the CCM.
613 USB Log File Creation Fault
When updating the CCM, DMC and DPC programs from a flash drive, a log file called CCM_LOG.TXT is created on the flash
which reports on the results of the update including any problems. If that log file can’t be created you get 613. This may
be a problem with the flash drive having too many other files on it or a problem with its format that may not be compatible
with the CCM.
1. Try putting the update files on a different, preferably empty, flash drive.
2. Or save all the flash drive files in another place on your computer, then delete all the files on the flash drive. Now copy
onto the flash drive only the files required for program updates.
3. If the above doesn’t work, making sure you still have copies of the files, format your flash drive which erases everything
on it. Now load only the files required for program update.
