Operating amperage should not exceed the value listed on the vibrator label. If
it does, it is most likely due to faulty mounting. Check your mounting welds, and
re-tighten bolts if necessary. See TROUBLESHOOTING for more info.

All US Models are single phase, 50/60 Hz. Standard 115 volt
units can simply be plugged into a grounded circuit. 230 volt
units are shipped without a plug and require hardware and/or
plug to connect to your circuitry. Always
consult professional electricians with
any questions or concerns for
electrical installations.

To change the force:
Disconnect power and remove both end covers.1)
Remove the cap screw that holds the outer eccentric to the inner eccentric2)
and turn the outer eccentric so that the numbered hole aligns with the
threaded hole in the inner eccentric. NOTE: You must set both ends of
the vibrator to the same setting.
Apply Loctite 242 (or equivalent). Replace the cap screw.3)
Replace both end covers. End cover bolts have a locking patch and do not4)

NOTE: If you INCREASE force of vibrator, you MUST take a new

specied limits.
NOTE: Only run intermittently (maximum running time of 30 min in any one hour
period. (See DUTY CYCLE section in Trouble Shooting section right).
VIBRATOR WON’T EVEN START?
1. Check power supply to unit. Are you getting the proper voltage? Has the thermal overload protection tripped?
2. 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.
3. Check eld & armature continuity. If either is burned or has a short, replace. If unsure how to check continuity, call
VIBCO or consult a licensed electrician.
DID THE VIBRATOR STOP RUNNING?
1. Check power supply to unit.
2. FOR Model US-900 & 1600 ONLY -- Has the thermal overload protection tripped? If overload protection has tripped,
wait a minimum of two (2) minutes then reset by switching rmly off and then on again.
3. Is there an unusual sound (banging) coming from the vibrator? This usually means that the vibrator has loosened or
the mounting is cracked.
Check the vibrator mounting bolts for tightness.
Check the mounting structure. New installations may be too weak. Reinforce mount area immediately by adding
stiffeners like angle iron or channel iron.
In existing installations look for cracks in mounting angle iron or plates. Also look for fatigued or cracked welds.
Repair and reinforce immediately.
Check vibrator and bracket connection to the form or mold. If clamps are loose or wedge is not properly inserted, it
may cause vibrator to run hot and cause internal damage. Brackets may need to be adjusted or replaced.
4. 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.
5. Are you running the vibrator continuously? All VIBCO high frequency electric models are rated for intermittent duty
only.
NOTE: Consult VIBCO for available timers to help run vibrators at proper intervals.
6. 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 US Models are rated for INTERMITTENT DUTY only.
Use 50% duty cycle where maximum run time = 30 minutes in any one hour period.
For run times of 10 seconds or less, use 1:7 ratio for run time vs. off time. (example: 5 seconds on to 35 seconds off).
For run times longer than 10 seconds, any cycle is acceptable.
NOTE: Duty cycle can be increased by adding additional ventilation. Consult VIBCO for details.
