Desigo® Room Automation Fume Hood Cable Sash Sensor DXA.B130 und DXA.B200 A peripheral device to acquire the sash position of a laboratory fume hood for Siemens laboratory fume hood controllers.
Features ● ● ● Potentiometer measures the fume hood’s sash opening Wire hook to quickly attach to the sensing object Removable mounting bracket to accommodate various mounting options Use The cable sash sensors are compact, economical and water-resistant devices with flexible cables, spring-loaded spools and a potentiometer to detect and measure linear position. Functions The cable sensor measures a fume hood’s sash opening. The sensor unit consists of a cable with hook, roll, spring and potentiometer.
Notes Security CAUTION National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. Safety notes Use the cable sensor as described and follow the listed precautionary measures. ● Opening the sensor housing damages the sensor. ● Do not allow the cable to snap back to the sensor.
Cable guidance and attachment The cable is attached to the sensing object / fume hood sash with a hook. The cable can be damaged and/or may rip if the sensing string drags on the insertion hole or other objects. The cable must be laid in a protected area. The cable must be pulled straight from the sensor housing. Cable movement must be parallel to sash movement; angle deflection of max. 3 degrees. Mounting on the fume hood Note Do not mount the potentiometer inside the fume hood work bench.
Caution: Attach the sensor above the topmost position of the front slider, as otherwise deflection rollers are needed. Alternatively, mount the cable on the back of the fume hood. Attach the cable to the counterweights. Caution: Make sure there is sufficient space for service. Mounting for sensing paths longer than 2032 mm (80 in): The sensing unit must be extended e.g. by a second, deflected cable for sensing paths longer than 2032 mm (80 in).
