Motor Mounted Speed Control Bison's new 90V PMDC speed control was designed for applications that require a convenient location Designed to be easily field mounted on Bison PMDC motors, the speed control is mounted within an aluminum extrusion for superior heat dissipation. A simple knob provides a convenient on-off switch. Three adjustable potentiometers provide settings for minimum RPM, maximum RPM, and current limit. A pre-wired three foot long cord with plug Simple Mounting and Assembly Allows the drive to start working for you in the field Easy Operation Speed is controlled with a simple on/off potentiometer in conjunction with current limit, min. speed, and max. speed settings Durable aluminum housing with steel cover plates disperses heat more efficiently Includes Power Cord with Plug Three foot power cord is included with a NEMA 5-15P More Consistent Speed Under All Loads SCR circuitry provides much more consistent speed throughout the motor's rated torque Gear & Engineering Corp.

ption B: CALIBRATION MINIMUM RPM (MIN RPM) The MIN RPM setting determines the motor speed when the speed adjust potentiometer is turned full counterclockwise (CCW). AMP LIMIT (AMP LIM) The AMP LIM setting determines the maximum torque for accelerating and driving the motor. The factory setting is 2.5A. To Calibrate: 1. Set the MIN RPM trimpot to full CCW. 2. Turn the speed adjust potentiometer full CCW. 3. Adjust the MIN RPM trimpot until the desired minimum motor speed is reached. To Calibrate: 1. With power disconnected, connect a DC ammeter in series with the armature. 2. Set AMP LIM potentiometer...
