LED product safety precautions

Safety features

This product is equipped with the following safety features, based on JIS C6802 “Safety of laser products.”

■Remote interlock

UV irradiation can be stopped by opening the INPUT terminal “INTERLOCK (11)” on the rear of the controller. It is shorted with a shorting bar as a factory default.

■Control by a key switch

The controller unit of this product is started via a key switch. Ensure that the key is removed while this product is not in use.

■LED radiation emission warning

Turning ON the key switch enables the irradiation of LED UV light, which turns on the irradiation warning indicator on the front panel of the controller. If the LED connection cable is longer than 2 m, or if the controller unit is installed in an invisible part of the equipment, another warning indicator needs to be provided in a visible location around the LED head.

(OUTPUT terminals “+5V” (23) and “COM” (24) on the r ear of the controller output signals when the key switch is turned ON.)

Stays on during irradiation

The emitting channels are indicated by a red light, either still or flashing.

■Emergency reset

If an error occurs, eliminate the cause and then hold down “SET” for more than one second to clear the error.
