SIMPLIFIED INSTALLATION INSTRUCTIONS IMPORTANT – Read these simplified installation instructions before proceeding. These instructions are to be used as a reference only and are not intended to replace the detailed instructions provided herein. You must read the Safety Warning, on page 6, before proceeding. Note: A Plug-In Horsepower Resistor® and AC Line and Armature Fuses, supplied separately, must be installed in order for this product to operate. See Section 9, on page 21. Plug-In Horsepower Resistor® 1.1 AC Line Connection – Wire the AC line to Terminals “L1” (Line Fuse) and “L2”, as...

1.5 AC line Fusing – It is required that an AC line fuse (supplied separately) be installed in the AC Line Fuse Holder, as shown in Figure 1, on page 10. Select the correct AC Line Fuse, as described in Section 8, on pages 20 and 21. Fuse each conductor that is not at ground potential. 1.6 Armature Fusing – It is required that an Armature Fuse (supplied separately) be installed in the Armature Fuse Holder, as shown in Figure 1, on page 10. Select the correct Armature Fuse as described in Section 8, on pages 20 and 21. 1.7 Plug-In Horsepower Resistor® – Install the correct Plug-In Horsepower...

INTRODUCTION Thank you for purchasing the KBMM™ “Standard of the Industry” full-wave variable speed DC motor control, now with SMT construction. The control offers the user the ultimate in reliability and performance at an affordable price. The controls contain a unique patented super-fast Direct-Fed™ current limit circuit that protects the SCR power bridge against direct shorts 1. The reliability of the control is further enhanced with the use of high-surge, 25 Amp SCRs, and AC line and armature fusing 2, 3. The control is designed with KB’s exclusive Plug-In Horsepower Resistor® 3, which...

Auto-Inhibit® – Allows the control to be rapidly switched “on” and “off” using the AC line. Inhibit and Enable – Allows the control to be turned “on” and “off” using electronic switching. Trimpots – Minimum Speed (MIN), Maximum Speed (MAX), IR Compensation (IR), Current Limit (CL), Acceleration (ACCEL), and Deceleration (DECEL). Jumpers – AC Line Input Voltage Selection (J1 (Model KBMM-225D only)), Motor Voltage and DC Tach-Generator Selection (J2). Protection Features – MOV transient protection. Short Circuit protected (at motor only). Diagnostic LEDs – Power On (PWR ON) and Current Limit...
