This section is one section of a complete service

manual. Before starting any procedure, read all

warnings and instructions that are located in the

Service Guidelines chapter.

REPAIR/PROGRAMMING

Repairs

There are no internally serviceable components in the motor speed controllers. If a controller is faulty then it must

be replaced.

Note: Opening or disassembling a controller will void the comptroller warranty.

Programming

Taylor-Dunn does not support field modifications to the controller parameters.

Complete vehicle parameters are available by e-mail and can be uploaded to the controller using a laptop or PC

with the 1314 application and cable. Refer to the Tools section for part numbers.

If you have a special application that may require modified parameters, contact your local authorized Taylor-Dunn

distributor to submit a request to the factory. Note: There may be a fee to created a custom parameter set.
Instructions for obtaining parameter sets and how to upload to the controller are included with the application.

HARDWARE TORQUE

If hardware is not listed here, refer to standard torque
