This product should be installed and serviced by a qualified technician, electrician, or electrical main-

tenance person familiar with its operation and the hazards involved. Proper installation, which includes

wiring, mounting in proper enclosure, fusing or other over current protection, and grounding can reduce the

chance of electrical shocks, fires, or explosion in this product or products used with this product, such as elec-

tric motors, switches, coils, solenoids, and/or relays. Eye protection must be worn and insulated adjustment tools

must be used when working with control under power. This product is constructed of materials (plastics, metals,

carbon, silicon, etc.) which may be a potential hazard. Proper shielding, grounding, and filtering of this product

can reduce the emission of radio frequency interference (RFI) which may adversely affect sensitive electronic

equipment. It is the responsibility of the equipment manufacturer and individual installer to supply this Safety

Warning to the ultimate end user of this product. (SW effective 11/1992). Be sure to follow all instructions care-

fully. Fire and/or electrocution can result due to improper use of this product.

Definition of Safety Warning Symbols:

Electrical Hazard Warning Symbol – Failure to observe this warning could result in electrical shock

or electrocution.

Operational Hazard Warning Symbol – Failure to observe this warning could result in serious injury

or death.

2 SAFETY WARNING – Please read carefully.

This product complies with all CE directives pertinent at the time of manufacture. Contact the Sales

Department for Declaration of Conformity. Installation of a CE approved RFI filter is required (see

Section 14.12, on page 30). Additional shielded cable and/or AC line cables may be required along with a sig-

nal isolator (SI-6 (Part No. 9444)).

3 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 shorts1. The reliability of the control is further enhanced with the use of high-surge, 25

Amp SCRs, and AC line and armature fusing2, 3. The control is designed with KB’s exclusive Plug-In Horsepower

Resistor® 3, which eliminates the need for recalibrating IR Comp and Current Limit when the control is used on

various horsepower motors. In addition, the rating of the control can be extended to 1.5 HP for controls with 90

Volt DC output and 3 HP for controls with 180 Volt DC output, by the use of KB’s Auxiliary Heat Sink4. Models

KBMM-225 and KBMM-225D also allow operation of 90 Volt DC motors when used on 208/230 Volt AC line

input 5.

The versatility of the control is confirmed by its extensive list of standard features, such as: selectable armature

and tach feedback and adjustment trimpots for minimum speed, maximum speed, current limit, IR compensation,

and linear acceleration and deceleration. The control includes Auto-Inhibit®, which eliminates surging during rapid

AC line switching; pulse transformer triggering, which provides cogless operation at low speed; and superior noise

rejection circuitry, which eliminates false starts and blown SCRs. Enable (normally closed) and Inhibit (normally

open) functions provide electronic switching of control output.

The output voltage of the control is a linear function of the Main Speed Potentiometer rotation. In addition, the

control can be used in a voltage following mode by supplying an isolated analog input signal to Terminals “P2” (+)

and “P1” (-) 6. The control is compact in size (only 4.30” X 3.64” X 1.25”) and easily replaces all competitive speed

controls. The control is supplied with a 5 k ΩMain Speed Potentiometer and QD terminals. All models are UL

Listed (USA and Canada) and CE Approved.

Notes: 1. Short circuit protected at motor only. 2. KB Limited Warranty applies. See page 32. 3. Fuses and

Plug-In Horsepower Resistor® supplied separately. See Sections 8 and 9, on pages 20 - 22. 4. Part No. 9861.

See Section 14.1, on page 30. 5. Step-Down operation. 6. If an isolated signal input is not available, or if using a

4 - 20 mA DC signal input, install the optional plug-on SI-6 Signal Isolator (Part No. 9444).

3.1 Standard Features

1 Plug-In Horsepower Resistor® – Eliminates the need to calibrate the control for IR Compensation

and Current Limit when used on various horsepower motors.

2 Auto-Inhibit® – Allows the control to be rapidly switched “on” and “off” using the AC line.

3 Inhibit and Enable – Allows the control to be turned “on” and “off” using electronic switching.

4 Trimpots – Minimum Speed (MIN), Maximum Speed (MAX), IR Compensation (IR), Current Limit (CL),

Acceleration (ACCEL), and Deceleration (DECEL).

5 Jumpers – AC Line Input Voltage Selection (J1 (Model KBMM-225D only)), Motor Voltage and DC

Tach-Generator Selection (J2).

6 Protection Features – MOV transient protection. Short Circuit protected (at motor only).

7 Diagnostic LEDs – Power On (PWR ON) and Current Limit (CL).

8Model KBMM-125 operates on 115 Volt AC line input with 90 Volt DC motors.

9Model KBMM-225 operates on 230 Volt AC line input with 180 Volt DC motors or 90 Volt DC motors

(step-down). - Jumper Selectable.

10 Model KBMM-225D can operate on 115 Volt AC line input with 90 Volt DC motors and 230 Volt AC

line input with 180 Volt DC motors or 90 Volt DC motors (step-down). - Jumper selectable.

11 Armature or DC Tach-Generator feedback.

Notes: 1. Step-down operation: motor may have reduced brush life. Consult motor manufacturer. 2. Performance is for SCR rated permanent magnet motors

only. Lower performance can be expected with other motor types. Factory setting is for 3% load regulation. To obtain superior regulation, see Section 11.6, on

page 27.
