Introduction

General MARTIN

and manufactured to ensure the best performance and reliability in severeduty applications. The vibrator motor has a recommended operational ambient temperature and mounting surface temperature range of -22 to 104° F (-30 to 40° C). If operating the motor in environments beyond these temperatures, call Martin Engineering, as the vibrator may require rating reduction, more frequent lubrication, or lubrication substitution.

The explosion-proof MOTOMAGNETIC® Electric Vibrators (CDX models) have been tested and approved by Underwriters Laboratories Incorporated (UL) and the Canadian Standards Association (CSA) for use in Class I, Groups C and D, and Class II, Groups E, F , and G hazardous locations. CDX V ibrators have been approved by KEMA for Gas Group IIB and have the flame-proof rating of EEx d IIB T4. CDX vibrators are rated for a maximum ambient temperature of 104°F (40°C).

This manual provides instructions for installation onto steel bins and hoppers only. For installation onto other structures, call Martin Engineering or a representative.

The vibrators in this manual may be referred to by their model numbers or part numbers. T able V in the “P art Numbers” section provides model numbers and part numbers together with frame size. The following letter designations are used throughout this manual:

Before Installing Vibrator

The delivery service is responsible for damage occurring in transit. Martin Engineering CANNOT enter claims for damages. Contact your transportation agent for more information.

1. Inspect shipping container/pallet for damage. Report damage to deliv ery service immediately and fill out delivery service’s claim form. Keep any damaged goods subject to examination.

2. Remove vibrator from shipping container/pallet.

3. If anything is missing contact Martin Engineering or a representative.

Turn off and lock out/tag out all energy sources to conveyor/ loading systems to mounting structure.

4. Before installing vibrator, turn off and lock out/tag out all ener gy sources to conveyor/loading systems to mounting structure according to ANSI standards (see “References”).

IMPORTANT

WARNING

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.

Installing Vibrator

Installation

IMPORTANT

Read entire section before beginning work. This manual provides instructions for installations onto steel bins and hoppers only . For other in stallations, call Martin Engineering or a representative.

CAUTION

If installation instructions are not followed, structure and vibrator can be damaged. Abusing or handling vibrator carelessly will accelerate wear and shorten bearing life.

Mounting vibrator onto structure

1. See Figure 1. Locate vibrator in lower 1/4 to 1 /3 of structure slope length. If second vibrator is required, mount 180° from first vibrator and halfway up slope.

Figure 1. Locating Vibrator on Hoppers

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. c. Weld mounting plate onto structure.

Martin Engineering M3286-8/01 4 MOTOMAGNETIC

Electric Vibrators

3. If using MARTIN W -Beam Mount (or equi valent) or T-beam to mount

vibrator onto structure (see Figure 2), do the following: a. Locate beam so that vibrator can be positioned as shown in Figure 1. b. Extend beam at least 3/4 the length of sloped wall. Cut off end(s) of

beam if necessary to fit on structure.

c. Skip-weld beam in place: W eld 3 in. (76 mm), then skip 2 in. (51 mm).

Repeat for entire perimeter of beam. Do not weld last 1 in. (25 mm) of either end of beam or any corner.

d. Install vibrator onto W-beam mount or ECF bracket.

4. If installing vibrator onto hopper with female wedge mount already in place, use MARTIN vibrator.

Never weld structure with vibrator mounted and wired. Welding may cause damage to motor windings and bearings.

Locking Wedge (Figure 2) or equivalent to mount

CAUTION

T- be am

Use only new Grade 5 bolts and lock nuts to install vibrator. Old fasteners can break and cause damage to vibrator or structure.

Do not use split lock washers to install vibrator onto mount. Damage to vibrator could result.

Tighten mounting bolts in sequence shown in Figure 3. If not tightened in order, vibrator casting could be damaged.

5. Before installing vibrator onto mount, apply thread sealing compound to all bolts.

6. Install vibrator onto mount with new lock nuts, compression washers, and bolts according to T able I. Tighten bolts in order gi ven in Figure 3 to avoid damaging vibrator casting. (Contact fastener manufacturer for specific information regarding bolt torque.)

WARNING

If vibrator is mounted more than 6 in. (152 mm) above ground, install cable securing vibrator to structure. Without cable, vibrator could fall and cause injury.

8. Secure vibrator to structure by installing MARTIN® BBAC Cable Kit,

P/N 32271, or equiv alent as follows (cable is included with Mount Kit for Electric V ib r ators, P/N 32 401 -XX):

a. Weld D-ring (A, Figure 4) onto structure wall (B) above vibrator.

CAUTION

Before running cord to vibrator , mak e sure cord voltage rating equals or exceeds the voltage at which you will be operating the vibrator. It must have a minimum temperature rating of 221°F (105°C) and a minimum diameter as shown in Table IV. If wire is not proper diameter, cord grip will not tighten properly and vibrator could be damaged by moisture or material getting inside wiring compartment. If cord is damaged, it could short power supply or short to ground causing damage to vibrator.

2. See Table IV. Make sure wire diameter is within the range for your

vibrator’s frame size and cord grip.
