After Installing Vibrator
IMPORTANT
Read entire section before beginning work.
Checking shaft
rotation
1. Remove cap screws and washers, and remove vibrator end cap.
CAUTION
!
DO NOT run vibrator with eccentric weights removed.
Running vibrator with eccentric weights removed will damage
bearings.
WARNING
!
When checking shaft rotation with end cap removed, keep
hands away from swinging weights. Weights can crush fingers.
2. Start vibrator for one second, then stop.
3. Observe direction of motor rotation. If motor is not rotating in correct
direction, lock out/tag out energy source and reverse rotation. To reverse
rotation of three-phase vibrator, reverse any two of the three power supply
wires. To reverse rotation of single-phase vibrator, see Figure 5, diagram
1A or 1E.
4. Replace end cap, taking care not to pinch o-ring.
Adjusting
eccentric weights
NOTE
All MOTOMAGNETIC

Electric Vibrators have one set of
eccentric weights on each end of shaft. Eccentric weights are
set at 50% at factory (model CD18-3850 is set at 70%, and
models CD36-11000 and CD36-20000 are set at 100%). See
Figure 10.
The percentage increments on the weight adjustment disks are
percentages of the total force pounds listed on the nameplate.
For example, if the nameplate shows 8340 lb, setting the
weights to 50% would produce 4170 pounds of force.
IMPORTANT
For the most efficient operation, vibrator eccentric weights
should be adjusted to the lowest force setting required to move
the material. This will increase vibrator life and reduce energy
costs.
