Protection Circuitry
Protection Features
When output power of 20W or more in CLAMP mode or 45W or more in UNCLAMP mode is
detected, the unit will stop operating for safety. (see "7 – 1 Error code"03")
If the handpiece is pulled out of the connector during operation, it will stop.
To prevent the handpiece from forgetting to turn it off, the handpiece will stop automatically if it is still
unused when it is on. (see "7 – 1 Error code"13") (Time to stop can be changed by user settings. It
can also be disabled. see "6 – 2 Setting the forced stop time when not in use")
If the main power switch is turned on while stepping on the foot switch, it will be disabled for safety reasons.
Release the foot switch because the indicator on the operation panel blinks and a notification sounds. The drive
prohibit state is lifted and the unit can be used normally.
The handpiece temperature rise is predicted from the output power and if the tool is found to be generating
excessive heat, the handpiece heat protection function is activated, the display on the control panel flashes and
an audible alarm sounds.
After that, it automatically suppresses the output and keeps the temperature from rising, allowing for continuous
use. When the temperature drops, the indicator on the control panel blinks and the notification sound is
automatically cancelled.
(You can also disable it through user settings. 6 – 6 Setting the handpiece heat protection function")
