40 mm Beam Pitch General Purpose Area Sensor. Failure monitoring

Transcription

1 OTHER SUNX PRODUCTS NA0 SERIES 0 mm Beam Pitch General Purpose Area Sensor Diagnosis Self-diagnosis Interference prevention Slim and intelligent Refer to p.9l for the light curtain. Slim body Failure monitoring Close mounting The NA0 saves space as the volume is reduced to / of a conventional model. Conventional model NA0 When one of the following errors occurs, the self-diagnosis output is generated and three color indicators reveal the failure condition. Reduction of incident light intensity The NA0 monitors the incident light intensity for reduction due to dust or dirt on the front faces, or beam misalignment. Two sets of sensors can be closely mounted by setting different emission frequencies to prevent mutual interference. Easy modification of length The modular construction enables modification of the number of beam channels. It makes a design change or maintenance on the site very simple. Failure of the output transistor Any failure of the output transistor is monitored. Robust aluminum enclosure The modules are protected by a robust aluminum enclosure conforming to IP5 protection.

Designation Description Large indicator for area sensor 098 SF-IND With the large indicators put on the sensors, the operation is easily observable from various directions. (Refer to p.0 for details) Note: Two SF-INDs are required if they are to be mounted on, both, the emitter and the receiver. Slit mask Large indicator for area sensor The slit mask restrains the amount of beam emitted or received and hence reduces the interference between neighboring sensors. It is also used in cases when the beam intensity is too strong penetrating through the sensing object. Replace the original front cover with the slit mask. The large indicator can be easily mounted on the sensor head at the top. It also can be mounted on an area sensor already being used. However, the sensing range reduces when the slit mask is used. Sensing range Slit on emitter side:. m Slit on receiver side: m Slit on both sides: 0.8 m

6 PRECAUTIONS FOR PROPER USE Never use this product as a sensing device for personnel protection. For sensing devices to be used as safety devices for press machines or for personnel protection, use products which meet standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country. If this product is used as a sensing device for personnel protection, death or serious body injury could result. For a product which meets safety standards, use the following products. Type : SF-AH series (p.0l), SF-EH series (p.8l) Type : SF-A series (p.l), SF-N series (p.l) Mounting Do not use the sensor without the front cover or the enclosure. IP protection cannot be maintained and a contact failure may occur between the modular units. When mounting the sensor, the tightening torque should be.9 Nm or less. Setting of frequency selection switch Turn the frequency selection switches with the enclosed screwdriver and select the appropriate frequencies (in power supply off condition). When using one set of sensor Setting of frequency selection switches When using two sets of sensors When two sets of sensors are closely mounted as shown in the illustration on the right, set the switches as follows. Set the switches of both the emitter and the receiver at. The sensor does not function normally at other settings. Sensing Area B Sensor B Operation of indicator NA0 Refer to p.5l for general precautions. Red : Sensing output operation indicator...lights up when the sensing output operation corresponds to Dark state.

Setting of frequency selection switches Sensor B Sensor A Sensor A Set the switches of both the emitter and the receiver of Sensor A at, and both switches of Sensor B at. The sensors do not function normally at other settings. Tighten the four fixing screws and insert the front cover by pulling the cover stopper back. Prepare the new protection enclosure and front cover that matches the required sensing height. Insert the units and connect the end cap. Connect the interference prevention wires (INTER LOCK) of Sensor A and Sensor B together. of Sensor A of Sensor B Connect both interference prevention wires (INTER LOCK) V 0 V Connect both the 0V wires in common. V wires need not be connected in common. Note: The overall wiring distance between Sensor A and Sensor B must be within 0 m. The interference prevention wire length and the 0 V wire length between the emitters must be within 0 m each, too. Other Do not use during the initial transient time (0.5 sec.) after the power supply is switched on. Notes: ) Be sure to turn the power off before linking units. If this is not done, the sensor may get damaged. Notes: ) The end unit, either -channel unit or -channel unit, must be connected at the top of the module linkage. Notes: ) Be sure to put the end cap on the top of the beam channel NA0- or NA0--H. Notes: ) The cover stopper and four fixing screws are attached with the protection enclosure. 0
