4B P300 Series, Руководство по эксплуатации

Страница: 12 / 16

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 P300 is within the
minimum distance specified.
3. Start up machine.
4. If monitoring for speed see A, for proximity monitoring see B -
A. If the P300 is being used to monitor speed, 4B’s
Speed Master™ calibration and testing device
can be used to insure the P300 shuts down the machine at the correct percentage of slip. Shut
down will depend on your specific monitoring setup. 4B recommends an instant shutdown on any
belts slipping 20% or more of normal speed.
B. If the P300 is being used as a proximity switch, be sure that the target is not within range of the
sensor prior to testing. Use a metal putty knife or a small piece of metal and place it between the
sensing face of the P300 and the target. This will cause the sensor to energize the output, and
both the green and red LEDs will go on. Removing the putty knife will de-energize the output
signal and both LEDs will go off.

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.
