LIMITED WARRANTY

A.Warranty - LEESON Electric warrants that its products will be free from defects in material and workmanship for a period of one (1) year from the date of shipment thereof. Within the warranty period, LEESON will repair or replace such products that are returned to LEESON or to the nearest Branch Office, with shipping charges prepaid. At our option, all return shipments are F.O.B. LEESON or its Branch Office. This warranty shall not apply to any product that has been subject to misuse, negligence, or accident; or misapplied; or repaired by unauthorized persons; or improperly installed. LEESON is not responsible for removal, installation, or any other incidental expenses incurred in shipping the product to or from the repair point.

B.Disclaimer - The provisions of Paragraph A are LEESON’s sole obligation and exclude all other warranties of MERCHANTABILITY or use, express or implied. LEESON further disclaims any responsibility whatsoever to the customer or any other persons for injury to person or damage or loss of property of value caused by any product that has been subject to misuse, negligence, or accident, or misapplied or modified by unauthorized persons or improperly installed.

C.Limitations of Liability - In the event of any claim or breach of any of LEESON’s obligations, whether expressed or implied, and particularly of any claim of a breach of warranty claimed in Paragraph A, or of any other warranties, express, or implied, or claim of liability that might, despite Paragraph B, be decided against us by any lawful authority, LEESON shall under no circumstances be liable for any consequential damages, losses, or expense arising in connection with the use of, or inability to use, LEESON’s product for any purpose whatsoever. An adjustment made to the warranty does not void the warranty, nor does it imply an extension of the original one (1) year warranty period. Product serviced and/or parts replaced by a no-charge basis during the warranty period carry the unexpired portion of the original warranty only.

If for any reason any of the forgoing provisions shall be ineffective, LEESON’s liability for damages arising out of its manufacture or sale if equipment, or use thereof, whether such liability is based on warranty, contract, negligence, strict liability in tort, or otherwise, shall not in any event exceed the full purchase of such equipment.

Any action against LEESON based upon any liability or obligation arising hereunder or under any law applicable to the sale of equipment or the use thereof must be commenced within one year after the cause of such action arises.

Safety Warnings

SHOCK	AVOID	KEE	OID
HAZARD	HEAT	DR	ATION

•This symbol denotes an important safety tip or warning. Please read these instructions carefully before performing any of the procedures contained in this manual.

•DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a qualified electrical technician install, adjust and service this equipment. Follow the National Electrical Code and all other applicable electrical and safety codes, including the provisions of the Occupational Safety and Health Act (OSHA), when installing equipment.

•Reduce the chance of an electrical fire, shock, or explosion by proper grounding, over-current protection, thermal protection, and enclosure. Follow sound maintenance procedures.

Warning

It is possible for a drive to run at full speed as a result of a component failure. LEESON strongly recommends the installation of a master switch in the main power input to stop the drive in an emergency.

Circuit potentials are at 115 VAC or 230 VAC above earth ground. Avoid direct contact with the printed circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use a non-metallic screwdriver for adjusting the calibration trimpots. Use insulated tools if working on this drive with power applied.

Overview

The following is a quick-step guide to setting up the control. For more detailed installation information, read the Installation (page 4) and Calibration (page 10) sections of this user’s manual.

1.Mount the control using the 4 slotted holes on the heat sink. The slotted holes are 0.19 inches [5 mm] (see Figure 1).

2.Remove the plastic cover by unscrewing the 6 screws on the front cover and 5 screws on the bottom plate. NOTE: Do not remove the 3 screws securing the bottom plate to the heatsink.

3.Change the line fuse if necessary. If the horsepower rating of the motor being used is less than the maximum HP rating of the drive, the line fuse may have to be replace with a lower rated one.

3.Wire the control through the conduit holes, or optional aluminum hardware. NOTE: Do not connect the control while power is applied.

4.Assure that settings on voltage switches are correct (SW501 & SW502).

5.Apply power to the drive.

5.Calibrate the trimmer pots, if neccessary.

6.Re-install the plastic cover.

4	SPEEDMASTER™ OPERATION MANUAL

Installation

Mounting

174102, 174103 and 174107 drives may be vertically wall mounted using the four 0.19 inch (5 mm) slotted holes on the attached heat sink (see Figure 1, Page 2). For motor loads less than 5 ADC, the drive may be bench mounted horizontally, or operated without mounting.

Removing the Plastic Cover

Connections, calibration, and other settings must be made internally. After mounting, use the following procedure to remove the plastic cover and configure the control:

1.Remove the six (6) phillips screws on the front cover. NOTE: The two shorter screws (#6 - 32 x 2 ½) are for the two lower holes on the front of the cover (see Figure 2, page 6).

2.Remove the five (5) phillips screws on the bottom plate (see

Figure 2, page 6). NOTE: DO NOT remove the 3 screws securing the bottom plate to the heatsink.

Line fusing

Line fuses are preinstalled on all 174102, 174103 and 174107 drives. If the horsepower rating of the motor being used is less than the maximum horsepower rating of the drive, the line fuse may have to be replaced with a lower rated one. Refer to Table 1 for recommended line fuse sizes.

Connections

Warning

Do not connect this equipment with power applied.

Failure to heed this directive may result in fire or serious injury.

1.Install conduit hardware through the two 0.73” (18.5 mm) conduit holes or by using aluminum cord connectors attached to the line seal plate on the bottom of the case.

2.Connect external wiring to the terminal block as shown in

Figure 3, page 7.
