Page 4: Introducing
Rev. A3, 10/08 • Introducing The DCR-WEB is a non-contact loop control system that is shipped ready to be put into service. It has been completely tested at the factory and is easily configured to any application. The sensor is fully programmable to meet the needs of all different kinds of loop control applications.

Page 7: Installation
Accurate readings require a clear sound path to the intended target. The path should be free from obstructions and as open as possible. Follow the guidelines mentioned in “Understanding Ultrasonics”. The DCR-WEB should be installed using the 4 screws through 4 holes in the bottom of the enclosure. Inputs •...

4 screws. This will expose the terminal strip and 2 X 8 character display. Step 3: Wires can be pulled into the DCR-WEB through the strain reliefs on the enclosure. The screw terminal can be wired using solid or stranded wire between 16 - 20 AWG.
Page 9: Programming
Rev. A3, 10/08 DCR-WEB • Programming The DCR-WEB has a two line by eight character alphanumeric display. Four momentary push-buttons located under the cover, are used to program the sensor. The cover prevents the buttons from being accidentally bumped. The different modes can be easily accessed using the mode buttons, M-UP and M-DN.
Page 10: Programming Modes
DCR-WEB Rev. A3, 10/08 • Programming Modes For ease of programming, the DCR-WEB modes are grouped into phases of an application setup. The phases are: Operation Filtering Outputs Calibration Utilities This order should be followed for setting up any application.

Page 12 Rev. A3, 10/08 Example: Ignoring Intermittent Noise The transceiver in the DCR-WEB is tuned to detect sound waves within a range. There are certain external sources of noise in that range that can affect the proper operation of the sensor, high pressure air escaping is the most common source.
Page 13: Outputs
DCR-WEB Outputs The DCR-WEB contains 2 relays which are capable of handling a 5 A load. These relays have programmable BEGIN and END points as well as TYPE of operation. The relays can also be jumpered NO (default) or NC. *see drawing on earlier page of this manual.

Page 16: Calibration
Calibration Analog The DCR-WEB has an Isolated 0-10 V output. To set up this feature, enter the two end points. If the level is beyond the bounds of the window created by the two end points the voltage level will stay at the voltage level of the point it is nearest to.
Page 17: Utilities
As air temperature changes, so does the speed of sound. This change can cause 0.18% drift in distance for every °C change. The TEMPCOMP Mode allows compensation in the readings for this change. The DCR-WEB contains an internal thermistor which measures temperature in °F. By turning temperature compensation on, the effects of temperature changes will be reduced.

Page 20: Maintenance
DCR-WEB Rev. A3, 10/08 • Maintenance The DCR-WEB sensor does not require maintenance. However, a periodic visual inspection of the system would be in order. The transducer should be kept as clean as possible for optimum performance. Dust buildup may be removed from the transducer with a cloth or by low pressure air.
