Microwave Pulse Switch - Presence & Absence DetectionMANUALRev 1.0MountingSpecific ApplicationsFigure E - Mounted as Block Chute Switch1. When mounting to monitor in a flowing product suchas coal, ore or wood chips, position the microwave pathout of the direct flow stream. If at all possible, go behindthe flow stream or well in front of the flow stream.This will prevent any possibility of unwanted trips due toabnormal product flow from the conveying system. SeeFigure E.2. When mounting to monitor for absence/presenceor plugged chute conditions, the MPS & MPR must bemounted opposite each other observing correct elevationand orientation. The system should be mounted in sucha way so that as product backs up, the beam will bebroken. Refer to Figure E for an example.Receiving Unit(MPR)PRODUCT FLOW3. When mounting to monitor flow/no flow and pluggedchute conditions, one MDS and one MPS/MPR unitsmust be used. The MPS and MPR provide the pluggedchute detection and are mounted opposite each otherin the same manner as the standard plugged chutedetection arrangement. The MDS however, is mounteddirectly above the MPR unit.4. When using the system as a proximity switch, themounting arrangement is application dependent andmust ensure proper operation even under worst caseconditions.Please consult your representative or the factory forspecific mounting arrangements.5. Mounting of the Microwave Pulse system on slopedvessel walls can be accomplished using the MicrowaveAdjustable Mount. This system allows the microwavesto be mounted to a sloped surface and then adjustedhorizontally for optimum performance and operation.The adjustable mount has an integral 4” weldment withUHMW polyethylene or PTFE (teflon) window options.Also included with the bracket is a vibration isolationkit (shock mounts) to help protect the electronics fromdamage. Each side wall of the vessel must not exceed30 degrees from the vertical centerline. To mount theadjustable bracket, simply weld the 4” weldment directlyto the vessel, install the window, mount the microwaveand adjust horizontally.See Figure G (page 11).Figure F: Flow/No FlowSultan 234 SeriesPRODUCTFLOWSending Unit(MPS)MDS Flow / No FlowSwitch15Microwave Series
