Crescent CS7010 - Troubleshooting; Fault Codes; A1 Main Controller

46Service Manual – CS7010™ 04 - Control System
Troubleshooting
When troubleshooting the machine, the CS7010 main controller should be one of the rst steps for most
troubleshooting scenarios. All of the distributed controllers throughout the system report their status back
to the main controller, including error codes. So when any of the controllers, including the MMC itself,
experience any sort of fault, the operator’s interface will display that/those fault(s).The tables in the next
section below describe each of these error codes, along with possible causes and remedies.
Many error codes will disable the applicable function to protect components, and may require the machine to
be reset in order to clear the condition prior to testing.
Another troubleshooting tool is the Output Test function in the service menu, and described on page 42.
Use the output test to manually activate devices to be able to make sound, heat, vibration observations, as
well as electrical measurements.
Fault Codes
All error codes are presented as 4-digit numbers (x-yyy), where the rst digit represents which controller is
reporting the error, and the remaining digits identify the actual error code.
