Section 1 

 

General Information 

 

Introduction 

This manual provides general information and operating 

instructions for Dynamatic air cooled, adjustable speed 

drives, consisting of a magnetic clutch and a flange 

mounted, AC motor. This manual generally covers all 

model numbers beginning with the letters DCD, followed 

by a hyphen and a number between 132 and 225, and 

ending with a hyphen followed by a number between 4041 

and 4181. Section 2 of this manual provides detailed 

information regarding the various models covered. 

 

All drives covered by this manual require a separately 

mounted Dynamatic® electronic controller to provide the 

necessary DC coil excitation and closed loop speed or 

torque control (see the controller manual for details). 

 

The information, drawings and data  included in this 

manual are generally applicable to the products covered 

but  may not include every detail pertaining to specific 

equipment provided for an individual customer order. 

Certified drawings and other information provided for 

specific items of equipment shall take precedence over 

this manual when the two differ in content. 

 

The instructions given are arranged in the order they 

would normally be used. They begin with general 

information and proceed from receiving, handling and 

storage, through installation, operation, start-up and 

maintenance to modifications. 

 

Technical Assistance 

While every effort has been made to provide a complete 

and accurate instruction manual, there is no substitute for 

trained, qualified personnel to handle unusual situations. 

It is best to request assistance through the 

DSI/Dynamatic® Service Repair Department, 1-800/548- 

2169. 

 

Safety 

Electrical rotating equipment and associated controls can 

be dangerous. Therefore, it is essential that only trained 

personnel be allowed to work with this equipment, under 

competent supervision. The danger is increased when the 

equipment is not handled, installed, maintained or used 

properly. 

 

Read appropriate sections of this manual before 

beginning work. Become especially familiar with all safety 

instructions and procedures. Heed any hazard labels on 

the equipment and be sure to instruct others in their 

meaning and importance. The various types of  labels 

used to alert personnel of hazards and their degree of 

hazard potential are as follows: 

DANGER: 

Used to call attention to an immediate hazard, 

where failure to follow instructions could be fatal. 

 

WARNING: 

Identifies hazards having possibilities for 

injury to personnel. 

 

CAUTION: 

Used to warn of potential hazards and unsafe 

practices. 

 

INSTRUCTION NOTE: 

Used where there is a need for 

special instruction relating to safety, proper operation or 

maintenance. 

 

Hazard Label Examples 

See Figure 1-1 for examples of the hazard labels that may 

appear on this equipment. Study them carefully; they are 

put on the unit for safety.  Acquaint maintenance and 

operating personnel with their appearance and content. 

 

Training 

Training programs are an essential part of safe and 

correct operation. Training provides the knowledge 

necessary to obtain top performance from your 

equipment. DSI/Dynamatic® recognizes this fact and 

conducts training schools to educate your plant personnel 

in safe maintenance and operating procedures. Special 

training schools structured around your specific 

equipment can be arranged. 

 

Receiving and Damage Claims 

This equipment is assembled and tested prior to shipment 

to make sure it functions property. After testing, the unit is 

carefully packed for shipment, using approved packaging 

methods. The carrier, in accepting the shipment, agrees 

that the packing is proper and assumes the responsibility 

for safe delivery. 

 

Although every precaution is taken to assure that your 

equipment arrives in good condition, a careful inspection 

should be made on delivery. Check all items against the 

packing list to be sure the shipment is complete; then 

carefully  inspect for damage. Any evidence of rough 

handling may be an indication of hidden damage. 

 

NOTE: 

Shipping damages are not covered by the 

warranty; the carrier assumes responsibility for safe 

delivery. If you note damage or missing items, 

immediately 

file a claim with the carrier. At the same 

time, notify the DSI/Dynamatic® customer service 

department. To expedite this service, refer to your 

equipment by purchase order, model, PRO and serial 

number.
