To change the force:
Disconnect power and remove the end cover.1)
Remove the cap screw that holds the outer2)
eccentric to the inner eccentric and turn the
outer eccentric so that the numbered hole
aligns with the threaded hole in the
inner eccentric (see below).
Apply Loctite 242 (or3)
equivalent). Replace the

Replace end cover. End4)
cover bolts have a locking
patch and do not need Loctite.
NOTE: Remove cap screw &

output. Align the arrow on the shaft to the
desired setting. The higher the number, the
greater the force.
Settings 1 - 3 are continuous duty rated
Settings 4 - 6 are intermittent duty rated only
NOTE: You must set both ends of the vibrator to the same setting.
4. Tighten eccentric bolts and reinstall end covers.
For vibrators mounted in tandem (side to side, not end-to-end) to produce linear motion
on tables & feeders:
To produce linear motion you must make sure vibrators rotate opposite from one another. Force
output labels should be opposite to one another when viewed from the same side (one increases
clockwise, the other counter-clockwise as in picture above). Follow instructions as above, & be sure
you set both vibrators & both ends to the same setting. Consult VIBCO for more details.
LEFT RIGHT
MY MATERIAL STILL ISN’T MOVING!
1. Did you put your vibrator in the right location? Did you mount your vibrator properly?
2. Do you have the right vibrator for the job? Does it provide enough force? Is it the right
frequency? Is it set to the maximum force? See eccentric setting info to left. Still not
sure? Call VIBCO Technical Support at 800-633-0032.
THE VIBRATOR WON’T START!
1. Check for blown fuses in vibrator. Replace with time-delayed 250V type.
NOTE: For SCR Models 50, 60, 100, 200, 300 & 400 fuse is located INSIDE control
box. For SCR Models 500 & 1000, fuse is located on lid of control box in holder marked
FUSE.
2. Check power supply to unit. Are you getting the proper voltage? NOTE: Remember that
SCR units are built with a 90VDC motor powered by 115VAC power, converted at
the speed control box.
3. Check eld continuity, if “open” eld winding is burned or has a short, replace eld. If
unsure how to check continuity, call VIBCO or consult a licensed electrician.
4. Check control potentiometer. If shorted, replace.
5. Check vibrator brushes for wear. Each unit has two brushes. Refer to full detail manual
at www.vibco.com for correct brush lengths. Replace if worn below minimum length.
VIBRATOR STOPS RUNNING!
1. Check for blown fuses in vibrator. Replace with time-delayed 250V type.
NOTE: For SCR Models 50, 60, 100, 200, 300 & 400 fuse is located INSIDE control
box. For SCR Models 500 & 1000, fuse is located on lid of control box in holder marked
FUSE.
2. Check power supply to unit.
3. Check vibrator brushes for wear. Each unit has two brushes. Refer to full detail
manual at www.vibco.com for correct brush lengths. Replace if worn below minimum
length.
4. Are you running the vibrator in a wet or washdown environment? Consult VIBCO about
washdown rated models.
5. Are you running the vibrator in a high temperature environment? Consult VIBCO about
high temp rated models. Refer to full detail instructions for proper mounting in high
temp applications.
6. Are you running the vibrator continuously? All VIBCO heavy duty models are rated for
continuous duty but only at certain eccentric settings. See diagrams to left for proper
output force settings for continuous duty.
NOTE: For best performance and vibrator life cycle, it is best to run them intermittently.
Consult VIBCO for available timers.
7. Are you repeatedly stopping and starting the vibrator? This can overload the vibrator.
Use the following guidelines for proper timing of starts and stops:
DUTY CYCLE
All SCR Models are rated for CONTINUOUS DUTY at frequency settings between 950 -
2500 vibrations per minute (VPM) -- which is approx. 25 to 60 on speed control dial.
For frequencies below 950 or above 2500 VPM, rating is INTERMITTENT DUTY. Use
50% duty cycle where maximum run time = 30 minutes in any one hour period.
NOTE: Duty cycle can be increased by adding additional ventilation. Consult VIBCO
for details.
