EPC- Your Encoder Solutions Partner Company History Encoder Products Company Inc. (EPC) is a leading designer and world-wide manufacturer of motion sensing devices. Founded in 1969 by William Watt, EPC began operations with a small line of custom encoders. Today, more than 40 years later, EPC’s popular Accu-CoderTM brand is the most complete line of incremental and absolute shaft encoders in the industry.

ENCODER BASICS Encoders provide motion control systems information on position, count, speed, and direction. As the encoder shaft rotates, output signals are produced, proportional to the distance (angle) of rotation. The signal may be in the form of a square wave (for an incremental encoder) or an absolute measure of position (for an absolute encoder).
ACCESSORIES Accessory items are often the difference between an installation that goes smoothly, and one that does not. EPC offers a range of accessories that are designed to not only make your life easier, but are manufactured to EPC’s high standards, ensuring years of trouble free service. In addition, they have been tested with the products they complement, so that you do not have to worry about proper form, fit, or function.
MOUNTING AND MECHANICAL INSTALLATION For over 40 years, our engineers have been designing encoders that are quick and easy to install. With a variety of mounting options available, your encoder should be a perfect match for your existing equipment. Accessories such as pivoting mounting brackets, measuring wheels, flexible couplings, etc., are available from EPC to ease installation. The first principle for every encoder installation is "Don't force it!".
Caution: Avoid damage to your Accu-CoderTM . The following actions may cause damage, and void product warranty. Do not shock or strike. Do not disassemble. Do not subject shaft to excessive axial or radial shaft stresses. Do not use a rigid coupling.

ELECTRICAL CONNECTION Proper wiring and grounding are essential for the longevity and proper operation of your Accu-CoderTM . In addition, electrical noise should be minimized to prevent improper counts and/or damage to the electronic components. Since an Accu-CoderTM can be used with a wide variety of input devices (PLC’s, counters, servo controllers, etc.), from many different manufacturers, it is important to determine proper wiring and connections before installation.
Radiated Electrical Noise • Noise can be generated by solenoids, relays, motors, starters, and similar devices. • Using shielded cables will dramatically reduce the effects of noise. Most Accu-CoderTM cables are double shielded (foil and braid) for optimum protection. • Ensure all equipment is properly grounded. (Motors, drives, shafts, etc.) • Connect encoder cable shield to ground at controller/counter end, leaving the end near the encoder unconnected.

TROUBLESHOOTING No Output/No Counts • If there is no mechanical movement, there will be no output. Therefore, verify that the Accu-CoderTM is rotating. • Check to make sure the proper supply voltage is present. It is best to do this at the Accu-CoderTM end, if possible. • Verify all wiring between the Accu-coderTM , the counter/controller, and the power supply. • Make sure that the proper signal type (OC, PU, LD, PP) is being used for the application.
