3 Section Introduction -. General This page provides instructions for operation and maintenance of Duff-Norton 305 and 605 Series electromechanical actuators. To ensure efficient, long and satisfactory use of this unit, read and understand the information herein, and follow the instructions closely. -. Industrial Use Only The actuators described and illustrated in this manual are intended for industrial use only and should not be used to lift, support or otherwise transport people unless you have a written statement from Duff-Norton which authorizes the specific actuator unit, as used in your application, as suitable for moving people. -3. Factory Preparation Each actuator is carefully assembled and tested at the factory to ensure that the electrical and mechanical components will function properly and that the actuator will lift its rated load. The motor current draw is checked to make certain that it is within Duff-Norton standards. Every effort has been made to deliver this unit to you in its factory approved state. You should, however, carefully inspect the actuator for damage that may have occurred during transit. -. Friction Disc Clutch The friction disc clutch is set so that the actuator will lift its rated load, or a lighter load if so specified, but will slip should the actuator be run into a jamming position at the end of its travel. Thus, under overloads, or jamming conditions, the clutch will slip while the motor continues to run. If necessary, the clutch can be set to slip at a lighter 305 Series Applied Load (lbs) With 5 V. 60 HZ AC Speed (in/min) 605 Series Applied Load (lbs) Standard Optional High Speed Standard Amps Optional High Speed N/A N/A load by connecting an ammeter in the line at the motor, loading the actuator, and, while operating, loosening the clutch hex nut slightly until ammeter reads the required current draw. (See table below.) Clutch is not effective at loads of 50 pounds or less. -5. Warranty and Warranty Repair Subject to the conditions stated herein, Duff-Norton will repair or replace, without charge, any parts proven to Duff-Norton s satisfaction to have been defective in material and workmanship. Claims must be made within one year after date of shipment. Duff-Norton will not repair or replace any parts that become inoperative because of improper maintenance, eccentric loading, overloading, chemical or abrasive action, excessive heat, or other abuse. Equipment and accessories not of Duff-Norton s manufacture are warranted only to the extent that they are warranted by the manufacturer, and only if the claimed defect arose during normal use, applications and service. Equipment which has been altered or modified by anyone without Duff-Norton s authorization is not warranted by Duff-Norton. EXCEPT AS STATED HEREIN, DUFF-NORTON MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OR MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. If you have any questions concerning warranty repair, please contact Duff-Norton. Authorization for return must be received from Duff- Norton before returning any equipment for inspection or warranty repair. 305 Series Applied Load (lbs) 605 Series Applied Load (lbs) With V. DC Speed (in/min) Standard Optional High Speed Standard Amps Optional High Speed N/A N/A Duty Cycle Chart 305 Series 605 Series # Duty Cycle (inches per hour) Applied Applied AC DC Load (lbs) Load (lbs) N/A N/A NOTE Some actuator external surface temperatures may reach 30 during use at or near maximum duty cycle. All ratings are nominal and are based on actuator being broken-in for approximately 500 inches of travel.

4 Figure -. Dimensions and Specificaions Section II Installation Note: Dimensions are subject to change without notice. -. To install the actuator, simply support and secure it with a single pin through one clevis end, secure it to its load with a second clevis pin, and then use the appropriate wiring diagram (AC or DC, Figure - or -) to connect the actuator to your power source. -. Avoid using a low voltage supply for the actuator, all wiring, switches, and other electrical components must be of sufficient capacity to carry the required current. -3. The translating tube is not keyed, and must be restrained from rotating. -. The axes of the clevis pins should be parallel so that the actuator can pivot without binding. A few drops of oil should be applied to the clevis pins on installation and periodically thereafter. -5. External wires for customer hookup are color coded as to direction of travel (see wiring diagrams below) CAUTION To protect the actuator and prevent damage from overtravel, it is recoommended that travel limiting switches be incorporated in the installation.

5 3-. A.C. This motor is an intermittent duty type motor having a five minute rating. Since the motor draws almost the same amperage at no load as at full rated load, it only takes 5 minutes of continuous running, regardless of how light the load may be, before the thermal overload relay cuts out. It then takes about 0 minutes before the motor cools sufficiently for the thermal relay to close. Make sure that the duty cycle to which the actuator is subjected is not too severe for the motor. The rear end bell of the motor has a rubber grommet, which when removed, -. Lubrication Duff-Norton recommends the use of the following lubricant in conjunction with proper maintenance procedures of this unit: Mobil XHP6 or XHP6. -. Required Tools A bearing puller and press, soft jaw table clamp and common hand tools are required for proper disassembly and assembly. -3. General Procedures Duff-Norton recommends following these procedures during disassembly and assembly:. Tag critical parts to facilitate reassembly.. Mark mating surfaces to ensure proper meshing. 3. Clean and lubricate parts as required.. All seals must be replaced at time of rebuild. 5. All screws, washers and other small common parts must be replaced if mutilated in any way. -.
