Possible error types include:

DISPLAY MESSAGES	STATUS	SUGGESTED SOLUTIONS
SSP_ERR	Indicates I2C error	Cycle power - Call factory
No DMX	DMX is not being received	Hook up DMX or turn on console

No Zero	One of the phases has failed to detect zero crossing. System is likely inoperable.	Call factory
Over Temp	One or more of the dimming modules has been shut off due to sensing of over-temp.	Make sure fan is running - Check rack filter - Check module input vents - Replace module.
Voltage Low	Rack is receiving insufficient voltage for initialized parameters.	Verify input voltage
Voltage High	Rack is receiving excess voltage for initialized parameters.	Verify input voltage
Arch Failure	The control module has been configured as a CME/CMEd orCMB/CMBd and communication with the architectural processor cannot be established.	The control module must be configured as a dimming module in the [Rack] menu, or call ETC.
Bypass Active	A power failure in the normal power feed was sensed. Dimmers have been driven to full, bypassing all control.	Restore normal power.
