When an instruction of a proper position exists, please follow Set mark the instruction. Usually it is used between scales 4-7 (6-7 for full wave system and 4-5 for half wave system).
- Page 26 (10) Power supply OFF ①Please turn off the power after confirming that the driving has stopped. When LED is turned off, "LV" is displayed once. This is not abnormal though. Moreover, it is likely to take more than five seconds for LED to go out. ②The electric charge remains in the internal circuit although LED goes out.

When the protection function operates, it is short-circuited between terminals C2-EM. The reset work is necessary when stopping due to the protection function. Please reset it after investigating the cause that made the protection function to operate and executing the countermeasure (Refer to the next page for reset).
