H. D. in. Further, since a red alignment marker has been provided, setting can be done while confirming the detection point projected on the work-piece. Wide sensing area Conforming to EMC Directive (-CPS only) ong sensing range type Since the view field is " mm ". in at a sensing distance of mm. in, the hot melt glue can be detected even if its position of application varies slightly. Sensing range mm (. in) Incorporated with red marker View field " mm ". in approx. Sensitive and reliable detection The spot type reliably detects a hot melt drop of mm. in diameter at C F, or more, and the long sensing range type reliably detects a hot melt drop of mm. in diameter (equivalent to mm.. in) at C F or more. ong sensing range mm. in ong sensing range type A long sensing range of mm. in max. is possible. Hot melt glue can be reliably detected not only on small pharmaceutical or confectionary boxes, but also on large cardboard boxes. Suitable for high speed production line As the response time is ms or less, the series reliably detects hot melt adhesives even where product boxes flow extremely fast. However, for the long sensing range type, this is valid ( for a sensing distance of mm. in or less. ) Short beads of hot melt glue with operation indicator ong sensing range type Since the operation indicator lights up when hot melt glue is detected, position alignment of the sensor head is easy.

Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous parts of machinery. It is a normal object detection sensor.

Verify that the supply voltage variation is within the rating. If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal is connected to an actual ground. In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. The sensor head cable cannot be extended. Others Since the series employs a differential method for sensing, if the length of the box or its traveling speed is different from that at the time of teaching, proper sensing may not be possible. Make sure to teach under the actual sensing conditions. If the sensor is used in an environment of marked temperature changes, perform the teaching periodically for stable detection. Do not use the series during the warm-up time ( sec. approx.) after the power supply is switched on. Further, do not touch any key during the warm-up time, as this may erase the sensitivity settings stored in the controller. In case the power supply is switched off in a mode other than the mode, take care that operation commences in the channel selection mode when the power supply is switched on again. Avoid dust, dirt, and steam. Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. Wipe the lens of the sensor head clean with a cloth damped with ethanol if hot melt glue, dirt, etc, sticks to it. Make sure to detect the hot melt glue with the sensing object moving. Stationary hot melt glue cannot be detected. The time duration for detecting hot melt glue should be sec. or less. If this time duration exceeds sec., OUT automatically turns. Take care that, in this case, it may take approx. sec. max., after being brought to the no-detection state, for the sensor to return to the stable sensing condition. Do not place any heat source such as an incandescent lamp around the sensor head or the hot melt glue application area. It may cause a malfunction. If some thermal reflector (glossy object, etc.) exists near the hot melt glue application area, the Hot melt applicator Heat source Controller reflected heat may cause an error. In this case, install a heat shield, etc., to make sure that the reflected heat does not reach the sensor head. Make sure that sunlight, or light from an incandescent lamp or fluorescent lamp does not enter the sensor head directly.

Press the key for sec. or more. After that, the key enables you to select the,, and. modes in rotation. Select, the sensitivity level set-up mode. Adjust the sensitivity level with UP and DOWN keys. After teaching, the sensitivity level is set to evel, i.e., the center of well-glued and non-glued levels. As the sensitivity level is increased, it becomes more difficult to detect a hot melt glue of less quantity. mif decreasing the sensitivity level, there are instances when the level cannot be decreased beyond a certain point. Press the key for sec. or more to return to the mode. Presence / absence detection function ength evaluation function () Presence / absence detection function This function examines the presence of even a small quantity of hot melt glue during the external synchronization signal input period and if it is detected, the result is OK. Otherwise the result is and OUT is turned (-CS: ) ( sec. approx.). <Time chart> Applied hot melt glue -CS -CS synchronization input -CPS synchronization input OUT Box T No Box Box T Hot melt glue T T NO hot melt glue High ow High ow ength evaluation function This function examines the length of hot melt bead applied on every box. It measures if the time duration of detecting hot melt glue is longer or shorter than the criterion predetermined with well-glued articles. If the result is, OUT is turned (-CS: ) for sec. approx. As the evaluation is done by feeding the synchronization signal of the moving boxes into the controller, the series can adapt to a change in line speed. <Time chart> Minimum GOOD Maximum If the allowable range is set at Hot melt bead length -CS -CS synchronization input -CPS synchronization input OUT -CS OUT -CS -CPS OUT T T GOOD T T T T T T T GOOD High ow High ow Th sec., Th sec., Tj ms, Th sec. approx. T, the time duration of the external synchronization input pulse, is sec. max. Further, the upper limit of the hot melt glue detection time T is sec. and the time taken for stable operation of the length evaluation function is ms max. T, the time duration between two synchronization input pulses (box passage signal), should be ms or more. OUT is output when the external synchronization input rises to High level. (In case of -CPS, the external synchronization input operation is reversed.) If the next external synchronization signal is input while OUT is being output, in case of -CS, OUT becomes and, in case of -CS or -CPS, OUT becomes at that instant.

PRECAUTIS FOR PROPER USE Step Operation Refer to Sensitivity setting on p. and teach the series. If teaching has already been done, carry out the operations from procedure. If a different channel is being set, select the channel by referring to Sensitivity setting on p.. While teaching, non-glued articles must be taught before well-glued articles. While teaching the series, make sure to input the external synchronization signal (box passage signal). In case OUT is used, input the external synchronization signal (box passage signal) even at the time of teaching. Press the key for sec. or more. After that, the key enables you to select the,, and modes in rotation. Select, the length evaluation mode. Press the UP key and the DOWN key to set the length evaluation level for presence / absence detection function and length evaluation function. Normally, it is set to presence / absence detection function. (evel ) In case of using presence / absence detection function Set to evel (presence / absence detection level). In case of using length evaluation function Set to evel to (length evaluation level). The allowable range of the bead length (detection time duration) is set as a ( ) percentage relative to the reference bead length of well-glued articles. The level indicators represent % each. evel indicator The allowable range for length evaluation can be adjusted from % to % % results in an operation which is the same as presence / absence defection function. (e.g.) In the right figure, the allowable range is set at %. If the reference bead duration of well-glued articles is. sec.;. sec. (. sec. %) h GOOD h. sec.

Since it extends the output duration of OUT by a fixed time interval, it is convenient to detect short hot melt beads on a quick production line or to send the signal to a device having a slow response time.
