Before Installation
!
WARNING
If equipment will be installed in an enclosed area, gas level or
dust content must be tested before using a cutting torch or
welding. Using a cutting torch or welding in an area with gas
or dust may cause an explosion.
5. If using a cutting torch or welding, test atmosphere for gas level or dust
content.
6. Mounting surface must be strong and flat, 0.01 in. (0.25 mm) across
vibrator feet. (This will minimize internal stress to vibrator casting when
tightening mount bolts. W elding in the area of the mounting surface could
affect its flatness.)
7. Make sure mounting surface is free of paint and debris, and foot of
vibrator is clean.

!
CAUTION
Never weld structure with vibrator mounted and wired.
Welding may cause damage to motor windings and bearings.
IMPORTANT
The object of rotary vibration on bins, hoppers, and chutes is
to transmit vibration through the wall into the product
contained inside. If structure is not made rigid, vibrator may
draw high amperage and move material less efficiently.
Make sure structure is fr ee of paint before mounting vibrator.
2. If using customer-supplied mounting plate to mount vibrator onto
structure, do the following:
a. Make sure plate is at least the size of vibrator base.
b. Locate plate so that vibrator can be positioned as shown in Figure 1.

3. If overload trips during operation, fix problem before resetting.
!
CAUTION
For equipment using two vibrators, the two motors must be
electrically interlocked. If using a single contactor , each motor
must be provided with separate overload protection. The
motor control circuit must be arranged so that if one motor
becomes de-energized, the other motor will automatically and
immediately become de-energized. Failure to properly
interlock motors could result in severe damage to equipment
if one vibrator fails.

After Installing Vibrator
IMPORTANT
Read entire section before beginning work.
Checking shaft
rotation
After Installation
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. W eights 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 reve rse rotation. To reverse
rotation of three-phase vibrator, re verse any two of the three po wer 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.
NOTE
Adjusting
eccentric weights
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 incr ements on the weight adjustment disks ar e
percentages of the total f orce 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 r equired to move
the material. This will increase vibrator life and reduce energy
costs.

Damage to vibrator can result.
Do not operate vibrator motor at frequency higher than specified on
nameplate. Throughout frequency range, verify that each line current does not
exceed current rating on nameplate. If reading is higher than nameplate,
consult inverter manual. If necessary, adjust inverter, reduce eccentric weight
setting, stiffen vibrator mount location, or move vibrator to more rigid
location. After making adjustment, check line current again to ensure line
current does not exceed nameplate rating.

Maintenance
IMPORTANT
Read entire section befor e beginni ng work. Allow vibrator to
cool to ambient temperature before working on it.
NOTE
All vibrators are lubricated at the factory.
!
CAUTION
Use only prescribed grease in vibrator. If a different grea se is
used, vibrator can be damaged and warranty will be void.
Use only prescribed amount of grease to lubricate vibrator.
Too much grease will cause bearings to overheat and result in
premature bearing failure.
Maintenance
Lubricating
vibrator
1. See Table V for lubrication schedule and amount of grease required for
your vibrator . Unless specified otherwise, lubricate the vibrator after each
2000 hours of operation.
!
CAUTION
For 3600 rpm machines operating continuously or for long
periods of time, reduce lubrication time and amount as sho wn
in step 2. Failure to do so could run bearings dry and destroy
unit.
2. If motor housing temperatures exceed 194° F (90° C), cut lubrication time
and amount in half for every 18° F (10° C) increment that meets or
exceeds 194° F (90° C). For example, if CD9-1410 motor housing
temperature is 204° F (96° C), use 4.5 grams of grease per bearing e v ery
1000 hours. (Maximum bearing temperature allowed is 248° F [120° C].)
For motor housing temperatures above 212° F (100° C), consult Martin
Engineering or a representative.
NOTE
Kluber grease may be purchased from Martin Engineering by
calling 800-544-2947 or from Kluber Lubrication by calling
603-434-7704.
3. For CD9, CD12, and CD18 model vibrators, lubricate frame size 35
and larger vibrators with Kluber Isoflex NB U 8EP grease only . For CD36 model vibrators, lubricate with Kluber Isoflex NBU15 grease only.
Lubricate as follows:
a. Clean vibrator case around grease fitting with clean shop towel.
b. Insert grease gun into grease fitting. Add grease.
*Unless otherwise noted, lubricate every 2000 hours.
**Lubricate every 1000 hours.
†Lubricate every 750 hours.
††Lubricate every 100 hours.

eccentric weights, and each pipe plug in flange. Insert grease fitting.
Add grease. Remove grease fitting, and replace pipe plugs, eccentric
weights, and weight covers, taking care not to pinch o-rings.
b. For frame size 60 and 70 CDX models, remove pipe plug in each
Do not attempt to repair vibrator motor or replace bearings
yourself. If you attempt to do so during the warranty period,
the warranty may be void.
If vibrator motor needs repair or if bearings need to be replaced, call Martin
Engineering at 800-544-2947 for instructions.
At least quarterly, inspect vibrator, cable and connections as follows:
!
WARNING
Before inspecting vibrator, turn off and lock out/tag out
energy source to vibrator.
1. Turn off and lock out/tag out energy source to vibrator according to ANSI
standards (see “References”).
2. Inspect end caps for cracks and check cap screws for tightness.
3. Inspect cable for damage including cuts and abrasions. Replace if
damaged.
4. Inspect ground connection. Make sure ground connection to motor
enclosure does not exceed 0.1 ohm. Ensure screw on ground terminal is
tightened to proper torque (see Table II).
5. Make sure all nuts on connections on terminal block are tightened to
proper torque. Do not overtighten (see Table II).
