The 4B WDA sensor is designed to detect moving ferrous (magnetic) material passing within its sensing range, and is used in conjunction with a speed relay, PLC or with 4B’s Watchdog™ Elite and A400 Elite control units. The sensor will not detect non-ferrous material such as plastic, rubber, stainless steel or aluminium. -

INSTALLATION - CONVEYORS SCREW CONVEYOR - For speed monitoring on a screw conveyor, the sensor will need to detect a ferrous steel flight (target). If the housing is mild steel, cut a 4 inch or larger diameter hole in the housing and weld a 300 series stainless steel plate over the hole. - Page 14 OPTION 1: SENSOR DETECTING TARGET ON PADDLE - Under normal running conditions, the target bolt passes through the sensor’s field and a pulse is sent to the speed relay. If the chain becomes slack, the target bolt will drop below the field and the pulses will stop, causing the relay contact to change state.

NOTE The sensor depth can be adjusted by loosening the adjustment bolt on the mounting bracket, sliding the sensor to the required depth and retightening the bolt. Final sensitivity adjustments should be made using the potentiometer sensing range adjustment screw. WARNING Ensure that no ferrous steel, such as the machine’s frame is within the target sensing field. - Page 16 SPEED RELAY WIRING DIAGRAM (SIMPLIFIED) - The diagram below is a simplified wiring diagram for connecting the WDA sensor to a 4B Rotech Speed Relay (Model SR2V5-1). See speed relay and other applicable instructions for complete set-up and installation information.

3. Start up machine, the green LED shows the state of the pulsed output and flashes once for each target detected. The LED should be off when no target is detected, if not, reduce the sensitivity 4. If the sensor is not performing as expected, contact 4B. WARNING If the system does not alarm as required, then remove the machine from service until the problem has been diagnosed and corrected. -
