FineTek EDX2 Operation Manual

EDX2 SPEED MONITOR (SCREW-ON TYPE) Operation Manual
INTRODUCTION
The application of speed monitors requires sensors to have particularly high stability. The
product is widely used in conveyance systems in industries such as electric power,
metallurgy, coal, light, and food, to detect misalignment of transportation belts or irregular (too
fast or slow) speed of various rotating machines.
Metal housing encapsulates the sensor, which is the best choice for such applications.
Applications such as machine tools or metal processing, idling etc. will expose the sensor to
impact, wear, or contact with harmful liquids.

INSTALLATION
(1) The surface of the sensing shaft must be made of metal. (Figure 1)
(2) The sensing area size needs to be 30 * 30mm. (Figure 1)
(3) The EDX speed monitor's front probe must be £10mm (max) from the sensing
shaft. (Figure 2)
(4) Adjust the distance based on the material of the sensed. (Iron: 1.0, stainless
steel: 0.7)
(5) Supply voltage of 10~36 Vdc.
(6) The default value of the speed monitor, set at the factory, is 250±5 RPM.
(7) After the product is powered on for 15 seconds, the green light will activate
according to the contact form and speed setting
(8) The speed monitor uses the sensing rod to measure up to 500 RPM (MAX).
(9) Rotate the potentiometer counterclockwise for 1 turn to reduce the action point
by 10RPM. Rotate clockwise for 1 turn to increase the action point by 10RPM.
Example: The potentiometer (Figure 3) is adjusted by 1 to 2 turns
counterclockwise as required. The low-speed alarm setting (switch point) is about
240~230 RPM. It is activated when the rotation speed is below this setting.
