Warning!
It is imperative that the operator record the codes listed if safety
system fault detection occurs. This information will be needed to
identify the reason for the safety system fault detection. It is also
imperative that the codes are properly labeled as COMMAND,
CHANNEL 1 FAULT, CHANNEL 2 FAULT, CHANNEL 1
CRITICAL, and CHANNEL 2 CRITICAL.
The command register defines the mode of operation the machine was in
when the fault occurred by displaying one of these hexadecimal codes.
