FLAT MOTOR DRIVEN ROLLER CONVEYOR STRAIGHT AND CURVE TECH HANDBOOKZERO-PRESSURE CONTROLS: SENSORZONE PHOTO-EYEPOWER WIRESENSORThe standard photo-eye sensor for zero-pressure flat motor conveyor is a Banner #DS18VP6LP. This is a polarizedretro-reflective photo-eye sensor with a DARK Operate PNP (sourcing) output. Each photo-eye sensor must bepositioned to work with its own dedicated reflector. Visually align red beam to center of reflector. When poweris supplied to the Universal Control Flat Motor ZPA Module and a product is positioned in front of the photo-eyesensor, an amber light will illuminate. When product is removed from the zone, the light turns off. The sameamber light will indicate proper photo-eye sensor alignment with the reflector. If the sensor and reflector are notaligned, the sensor light will turn on. If they are aligned properly, no light will be illuminated on the sensor.The position of the photo-eye sensor controls the position of the product as it stops in the zone. Typically, photoeyesensors are positioned in the last 3 to 6 inches of the zone. Product construction, product weight andconveyor speed will all have an impact on the required stopping distance. If product is not stopping in thedesired location, adjust the photo-eye position accordingly. Zone stops as the product passes the photo-eyes,small products may hang up if conveyor speed is slow or photo-eye is not adjusted close enough to end of zone.WIRING INSTRUCTIONS FOR MODEL #DS18VP6LP PHOTO-EYE SENSORBrown Wire: +24V DC, connect to the (+) sensor terminal on the ZPA moduleBlue Wire: DC Ground, connect to the (-) sensor terminal on the ZPA moduleBlack Wire: Dark Operate Signal, connect to the (in) sensor terminal on the ZPA moduleWhite Wire: Light Operate Signal, not used(10-30 VDC, overhead current < 20 ma exclusive of load, 100 ma maximum output)<strong>FMDR</strong> TECHNICAL HANDBOOK 2014.124
