The Status Indicator flashes a 2 part code that indicates the status of the system.
When the Status Indicator is dark the system is ready to cut. It is normal for the Status Indicator
to flash when the GCM mode switch is placed in set mode. At system start up, the Status
Indicator flashes a 2 part code to indicate the CCM firmware version that is loaded into the
system. This code appears only once at start up. During normal operation the Status Indicator
may flash a code indicating an error or a condition that should be corrected. Some codes will
cause the system to cease operation to prevent damage to the hardware. Other codes will not
cause the system to cease operation, but will continue until the condition which caused the code
to initiate is changed.
Status codes appear in a 2 part sequence. The Status Indicator will flash a number of
times to indicate the first number in the code sequence, then pause for 1.2 seconds and flash
the second number of the code. After 4 seconds, the code sequence will repeat.
Example: The Status Indicator blinks 4 times, pauses, then blinks 3 times.
This code (4-3) indicates overheating coolant and will continue until the condition is corrected.
