Operations System Alarms Critical Alarms Continuous flashing both lights on either side of the control indicates a Critical Alarm . System will do a “Safe Shut Down,” and must be serviced before further use . When a critical alarm occurs, the system will automatically go to the selected “Fail Safe Response” mode. The system MUST be shut down and restarted for most critical alarms. Some functions may operate for a time after restart. See display on Control Unit to determine cause of alarm. If the alarm is caused by the Throttle Actuator hitting “Stop” - Wide Open Throttle (WOT) - the alarm will go away when the throttle is pulled back.
However, as with ALL Critical Alarms, the system must be serviced before further use. Non-Critical Alarms Intermittent flashing of both lights on either side the control (five seconds flash, normal for fifteen seconds, then repeating), indicates a Non-Critical Alarm . Acknowledge by a power up cycle. Continue to operate and have the system checked as soon as possible.
