These instructions must be read thoroughly before installation or operation.

WARNING:

To insure that drive is not unexpectedly started,

turn off and lock out or tag power source before proceeding.

Failure to observe these precautions could result in bodily

injury.

DESCRIPTION

FLEXIDYNE dry fluid couplings are a unique concept to provide

soft start and momentary overload protection for all types

of driven equipment. Standard NEMA-B motors with RPM

base speeds of 1750, 1160 or 860 are commonly used with a

FLEXIDYNE, yet other available power sources may be used with

the FLEXIDYNE.

The dry "fluid" in the FLEXIDYNE is heat treated steel shot. A

measured amount, referred to as flow charge, is added into a

housing which has been keyed to the motor shaft. When the

motor is started, centrifugal force throws the flow charge to the

perimeter of the housing, packs it between the housing and the

rotor which in turn transmits power to the load.

After the starting period of slippage between housing and rotor

the two become locked together and achieve full load speed,

operating without slip and with 100% efficiency.

Consequently, the motor accelerates instantly to base speed,

while the load starts gradually and smoothly.

WARNING: Because of the possible danger to persons(s) or

property from accidents which may result from the improper

use of products, it is important that correct procedures be

followed: Products must be used in accordance with the

engineering information specified in the catalog. Proper

installation,

maintenance

must be observed. The instructions in the instruction

manuals must be followed. Inspections should be made

as necessary to assure safe operation under prevailing

conditions. Proper guards and other suitable safety devices

or procedures as may be desirable or as may be specified in

safety codes should be provided, and are neither provided

by Dodge nor are the responsibility of Dodge. This unit and

its associated equipment must be installed, adjusted and

maintained by qualified personnel who are familiar with the

construction and operation of all equipment in the system

and the potential hazards involved. When risk to persons

or property may be involved, a holding device must be an

integral part of the driven equipment beyond the speed

reducer output shaft.

INSTALLATION

Install sheave on driven hub using screws and lockwashers

furnished. Torque screws to 580 inch-pounds. Do not use

sheaves with set screws that exert pressure on the driven hub;

they may distort the driven hub and damage the needle bearing.

Slide the FLEXIDYNE Drive on the motor shaft with collar as

close to motor as possible. Tighten key set screw securely

against motor shaft key. Tighten shaft set screw against motor

shaft. Note that drive hub must be installed on the motor shaft (or

on other installations it must be the first part of the FLEXIDYNE to

receive power from the power source) to permit proper operation

of the FLEXIDYNE Drive.

The flow charge recommended in Table 1 is the amount

per cavity required. To assure a more even initial

distribution of flow charge, remove filler plugs and pour ½

of recommended amount in both cavities. Replace filler

plugs being careful to clear threads of any flow charge.

Manually rotate the FLEXIDYNE housing several turns.

Remove filler plugs and pour in remaining amount of flow

charge. Clear threads as before, replace filler plugs and

torque to 200 in.-lbs. on sizes 11D & 11DL; 700 in.-lbs on

size 15D.

Attach AC ammeter (conventional clamp-on or equivalent)

to one line of the AC motor. Set range to cover 200% of

motor nameplate current.

Note maximum allowable acceleration time for FLEXIDYNE

as stated in Tables 1 and 2. Note: Table 2 lists starting time

capacity for starting cycles occurring more than once every

2 hours.

Push start button. Observe motor current during load

acceleration and number of seconds required to reach full

speed.

Increase amount of flow charge if:

A. Acceleration time reaches maximum allowable before

load is up to speed. Turn off power immediately if this

time is reached.

B. Acceleration amperage is below motor nameplate

Decrease amount of flow charge if:

A. Acceleration time is less than 1½ seconds.

B. Acceleration amperage is above 200% of motor

nameplate.

CAUTION:
