Troubleshooting; Faults; Fault Code Table - Cynosure Cynergy Operator's Manual

Faults

The user may encounter faults while operating the laser system. When a fault occurs a fault code
appears on the display followed by a brief text message. There are two types of faults: 1) errors,
or 2) warnings.
Errors faults are critical and will cause the laser to stop operating. These faults codes begin with
the prefix 'E' meaning error. Some of these errors require that you contact the Cynosure Service
Department.
Warnings are faults that indicate an improper laser state or operator error. These fault codes
begin with the prefix 'W' meaning warning. For example, an attempt to fire the laser without a
fiber present causes a warning fault to occur. The operator can usually correct these faults.
All faults codes and messages are listed in the following table, along with the probable cause and
corrective action if applicable.

Capacitor bank or HVPS wire shorted. No read back
voltage. Needs service.
Broken lamp or blown fuse. Needs service.
HVPS over-temperature.
Fuse fault at power up. Needs service.
Dump always on. Needs service. Dump shorted. Failed
dump TX. HVPS failed.
Dump not working. Needs service. Fiber connections
broken to cap bank. HVPS disconnected or failed.
