M800 Speed Switch
Inductive Speed Switch Sensor
M8001V10C, M8002V10C, M8001V10A

The M800 Elite Speed Switch is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the M800 Elite works in the harshest of conditions.

An inductive sensing device located in the nose of the M800 Elite enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. During installation the M800 Elite is set to the normal machine shaft RPM by calibrating with the magnet provided. The internal microprocessor sets the alarm and shutdown relays.

SpeedMaster™

4b Speedmaster - Testeur de contrôleur de rotation
SpeedMaster™

The SpeedMaster™ with Pulse Pilot is the only device that accurately tests the calibration of a speed switch, and allows testing of the 10% alarm and 20% shutdown features of the sensor while installed on the machine shaft.

The SpeedMaster™ operates in two modes. Input mode is used to measure the pulse rate at normal speed. Output mode will allow the user to simulate belt underspeed for testing purposes.

The Pulse Pilot fits between the gap between the sensor and the target. The Pulse Pilot will have no effect on the operation of the speed switch until it is connected to the SpeedMaster™ and set to Output mode.

Whirligig®

4B Whirligig shaft sensor mount
Whirligig®

The Whirligig® is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300, and M800 speed switch sensors.

The sensor bolts to the Whirligig base plate and the complete assembly either bolts to the machines shaft through a M12 tapped hole, or is connected magnetically using 4B’s patented Mag-Con™ adaptor. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft. With the Whirligig, installation of speed sensors is now simple, safe and reliable.

X400 Elite Alarmswitch

X400 Elite
X400 Elite Alarmswitch

The X400 Elite is a microprocessor controlled low cost alarm indicator panel for use with level indicators, hazard controls and limit switch sensors. The X400 accepts signals from different sources in up to 8 zones, and is able to cause alarm and shutdown of the machine when an alarm condition has been detected. Alarm and status LEDs on the lid of the X400 provide quick location of alarm conditions. Alarm muting can be performed at the panel or by an optional remote push button to silence external alarms. If the system is muted, it will automatically reactivate when a new alarm is triggered. Testing can also be activated at the panel, providing full system verification.

PRODUCT DETAILS

What voltage is needed for the M800 Elite?  
  The M800 Elite is universal voltage 24 - 240 VAC/VDC.  

How do you calibrated the M800 Elite?  
  The M800 Elite is calibrated with a magnetic using the calibration point on the front of the sensor, please refer to the operation manual for details.  
     
When will the M800 Elite alarm and/or shut down the machine it is monitoring?  
  The M800 Elite will provide an alarm at 10% underspeed and can provide an automatic shutdown at 20%.  

Are the relays always open or closed?  
  The 10% relay is open when running and the 20% relay is closed when running.  

Why is the M800 Elite not working when mounting to the Whirligig?  
  There are two sets of holes in the base plate of the Whirligig, be sure to use the top holes to mount the M800 Elite flush to the Whirligig guard and target.
