TROUBLESHOOTING GUIDE
FAULT REMEDY
Set LED is Orange Calibration not accepted, need to recalibrate sensor (see page 9).
Set LED is Red
Follow procedure “RECALIBRATION FOR A DIFFERENT SETTING”. If the
set LED remains red, contact 4B.
Input LED does
not Illuminate
Check that you have a supply of the correct value across the brown and blue
wires. Slide a screwdriver blade across the face of the sensor, the input LED
should flicker. If not, contact 4B.
If the input LED does flicker, move the front face of the sensor closer to the
target and check the target size as specified under “INSTALLATION”.
Input LED Stays
on Permanently
Either increase the gap between the target and the shaft, or between the
target and the sensor face.
WARNING
If the system does not immediately shutdown as expected or alarm as required, then remove the
machine from service until the problem has been diagnosed and corrected.
TESTING AND COMMISSIONING
1. Check that the unit is correctly installed (see standard wiring diagram).
2. Check that the distance between the target, stud or bolt head and sensing face of M800 Elite is within
the minimum distance specified.
3. Start up machine, and wait for start-up delay to complete (set LED will be solid green).
4. 4B’s Speed Master™ calibration and testing device can be used to accurately test the alarm and
shutdown features of the M800 Elite. A metal putty knife or a small piece of metal can be used to
simulate a stop motion situation by placing the metal between the sensing face of the M800 Elite and
the target. After the initial start up delay, the machine should shutdown.
SPEED MASTER™
The Speed Master™ 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
Speed Master™ operates in two modes. Input mode
is used to measure the pulse rate at normal speed. Output
mode will allow the user to input pulses to the sensor 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 Speed Master™
and set to “output” mode.
