INCORRECT
Figure 12. Setting Sets of Eccentric Weights to Mirror Images
Initial start up/

current
Martin Engineering M3910-04/19
Adjust both sets of eccentric weights to same setting number
(mirror images) or force output will be uneven.
7. Repeat steps 2 through 5 for second set of weights. Set both sets of
weights to same setting number so they are mirror images, as shown in
Figure 12.
1. Close power supply disconnect switch and allow motor(s) to operate for
10 to 20 minutes.
2. If vibrator makes unusual or excessive noise, make sure mounting bolts
are tight and mount welds are not damaged.
Vibrator may produce loud noise during operation when
mounted on structure. See OSHA 1910.95 for guidelines. If
required, wear ear protection to avoid impairment or loss of
hearing.
3. Check decibel level of vibrator noise during operation. See OSHA
1910.95 to determine whether noise exceeds safe limits. If required, wear
ear protection to avoid impairment or loss of hearing.
Do not allow motor current to exceed nameplate rating. If
vibrator is operated continuously with line current above
nameplate rating, vibrator can be damaged.
4. After a few hours of operation, check each line current. If reading is
higher than nameplate rating, reduce eccentric weight setting, stiffen
vibrator mount, or move vibrator to more rigid location. After making
adjustments, check line current again to ensure line current does not
exceed nameplate rating.
