Adjusting The Vibration Intensity - OLI MVE J Serie Handbuch

MVE
C
THE ELECTRICAL CONNECTION MUST BE CARRIED OUT BY QUALIFIED PERSONNEL ONLY AND
WITH THE POWER OFF.
Ensure the voltage and frequency match the values on the identification plate of the motovibrator.
All the motovibrators must be connected to a suitable external overload protection, except for the motors of the MICRO MVE series, as even
if there is an event that causes a block of the rotor, the motor temperature does not exceed the value envisaged in
regulation EN 60034-1 par. 8.10.1 Tab. 7 When a pair of motovibrators is installed, each of them must be provided with its own external
overload protection, which in turn must be interlocked together to prevent the operation of just one motovibrator if the other one
accidentally stops. Always use delayed tripping circuit breakers to prevent them from being triggered upon start-up, when a large amount
of absorbed current can reach high levels (especially if the temperatures are low).
Overload protection NOT GREATER than 10% compared to the values on the data plate or the warranty will become null and void!
All the electrical components that the installer will insert in the electric motovibrator (e.g. overload protections, sensors) must be
compliant:
- For the ATEX IECEX II 2D certification: with ATEX directive 2014/34/EU, II 2D or a higher one
- For the north America certification: Art. 500 NEC, Art. C22.1 CEC
For the equipotential connection of the motovibrator, earth the machine by using the designated terminal on the casing (Fig.7).
NOTE: Ensure the terminal board cover gasket is positioned correctly, as an incorrect positioning might alter the IP protection rating

2.5 - ADJUSTING THE VIBRATION INTENSITY

!
This operation must only be carried out by qualified personnel and with the power off.
- Remove the side covers by undoing the screws and washers.
- Unscrew the clamping screw of the movable exposed conductive part (for Size 10 and MICRO MVE unscrew the clamping nut on the
shaft).
- Bring the eccentric exposed conductive parts to the desired value as shown in the TAB section, pages from TAB.183 to TAB.186
- The exposed conductive parts must be imperatively set in the same direction on the two ends (see Fig.1).
- Once the exposed conductive parts are brought to the desired value, tighten the clamping screw (clamping nut for Size 10 and MICRO)
by using a torque wrench.
CAUTION: Make sure no-one can touch or be hit by the rotating exposed conductive parts.
- If it is necessary to reverse the direction of rotation, use the terminal board connections after powering off the motovibrator.
- After performing the operation on both sides, refit the covers with the same screws and washers, making sure that the (OR) gaskets
are correctly positioned in their housings.
- For the tightening torques, see the TAB section page from TAB.188 to TAB.189.
