Watchdog™ Super Elite Monitoring System for Bucket Elevators or Belt Conveyors
The Watchdog Super Elite (WDC4) is easy to install and simple to set-up. The system processes signals from sensors for belt misalignment, belt speed & slip, continuous bearing temperature, pulley misalignment and plug conditions for bucket elevators or belt conveyors. When an alarm is detected it will sound an alarm and provide shutdown control of the elevator/conveyor and feeding system.
A 3.5” LCD screen displays the entire system status at a glance. Password protected controller settings can be set up either directly on the LCD screen, or by a PC application and transferred to the WDC4 via an SD card.
The Watchdog Super Elite can be connected directly to a PLC using the Modbus TCP/IP protocol, or integrated into HazardMon.com®. This secure cloud based solution provides live system status, graphs and historical data that is viewable on any web-enabled device (smart phone, tablet, desktop PC).
WDC4-AUXI-6AN - Provides the ability to connect 4 current loop inputs (4-20 mA) and 2 voltage inputs to the Watchdog control unit. Between 1 and 6 sensors can be installed with power and ground connections integrated into the expansion board.
The Whirligig is a fully guarded target for easy mounting of motion sensors like the P800 Proxswitch. The Whirligig is available with 1, 2, 4 or 8 pulse targets, and attaches to the machines shaft by a 1/2 in. tapped hole or magnetically using the
The SpeedMaster™ with Pulse Pilot is the only device that accurately tests the calibration of a speed switch, and allows testing of the alarm and shutdown features of the sensor while installed on the machine shaft.
The Touchswitch™ is an electromechanical limit-switch with no
moving parts, which detects tracking and misalignment
problems on bucket elevators and conveyors. Unlike a rub block that utilizes friction (heat) to activate, the Touchswitch is pressure sensitive (contact) for safer and more reliable monitoring.
Brass rub blocks process temperature information. When the belt from a bucket elevator or conveyor rubs against the brass block, heat is created from the friction which is then relayed to a temperature sensor generating an alarm.
The ADB series have been designed to allow the depth of the sensor to be adjustable. They screw directly into a bearing housing through the
existing grease zerk thread. Each sensor is fitted with a grease
zerk to allow lubrication of the bearing without the need for removal of the sensor.
The ADB Sensor Tester has been designed to test 4B adjustable depth bearing (ADB) temperature sensors in the field.
During planned maintenance or periodic testing, this diagnostic tool to verify the alarm and shutdown sequences of the control unit are functioning as expected.
Does 4B offer inspection, testing and commissioning services for your hazard monitoring systems?
Yes, the 4B Tech Team is available for on-site services. For more information, CLICK HERE.
Is the Watchdog Super Elite (WDC4) a direct replacement for the previous Watchdog Elite (WDC3)?
Yes, the WDC4 can do everything the WDC3 does and even more.
Can I upgrade my older Watchdog WDC3 to the new WDC4?
Yes, all WDC3NV46C models can be easily upgraded to the new WDC4. Previous Watchdog models (WDC3V46C,
WDC2V6C) can be upgraded with minimal hardware changes.
How much of a learning curve is there with the new WDC4 unit?
4B has designed the new WDC4 to be super user friendly with simple set-up and installation. If you are already familiar with the previous WDC3 model, you will be up an running with the WDC4 in no time.
The WDC4 has more sensor inputs than the WDC3, do I have to use all the inputs on the WDC4?
You can pick any combination of sensor inputs, the WDC4 is flexible based on your application.
Will the WDC4 communicate with my PLC or Hazardmon?
Yes, Modbus over Ethernet (TCP/IP) is built into the unit.
