EDX2 SPEED MONITOR (SCREW-ON TYPE) Operation Manual
INTRODUCTION
Applications such as machine tools or metal processing, idling etc. will expose the sensor to
impact, wear, or contact with harmful liquids.
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.

(6) The default value of the speed monitor, set at the factory, is 250±5 RPM.
(2) The sensing area size needs to be 30 * 30mm. (Figure 1)
(8) The speed monitor uses the sensing rod to measure up to 500 RPM (MAX).
(7) After the product is powered on for 15 seconds, the green light will activate
according to the contact form and speed setting
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.
(1) The surface of the sensing shaft must be made of metal. (Figure 1)
(3) The EDX speed monitor’s front probe must be £10mm (max) from the sensing
shaft. (Figure 2)
(5) Supply voltage of 10~36 Vdc.
(4) Adjust the distance based on the material of the sensed. (Iron: 1.0, stainless
steel: 0.7)
(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 1: Conveying equipment low-speed alarm 100RPM
(1) Install EDX2 on the conveyance equipment.
(1) Install EDX2 on the conveyance equipment.
(4) Adjust the rotational speed of the equipment to a normal speed.
(3) Once the rotational speed of the equipment stabilizes, adjust the potentiometer behind the
EDX2. Turn it counterclockwise until the green light is off (assuming NC alarm mode). The
100RPM low-speed alarm is now set.
(3) Once the rotational speed of the equipment stabilizes, adjust the potentiometer in the back
of EDX2. Turn it clockwise until the green light turns on and then counterclockwise until
the green light is off (assuming NC alarm mode). The 300RPM low-speed alarm is now
set.
Example 2: Conveying equipment low-speed alarm 300RPM
(2) Turn on the power for EDX2 and adjust the rotation speed of the conveyance equipment
to 300RPM. After 15 seconds, the product will start up. The green light will only light up
after 15 seconds.
(2) Turn on the power for EDX2 and adjust the rotation speed of the conveyance equipment
to 100RPM. After 15 seconds, the product will start up. The green light will only light up
after 15 seconds.
(4) Adjust the rotational speed of the equipment to a normal speed.

Assume that the output contact type is PNP/NO, the product supplies voltage, the
conveyance equipment has a rotation speed of < 250RPM, the green light of the product is
on, and the alarm output is activated. After waiting 15 seconds, if the conveyance equipment
speed remains < 250RPM, the green light will go out without any action. If the rotation speed
of the conveyance equipment is > 275RPM, the green light will light up and the output will
act.
