i.  SAFETY  WARNING! — PLEASE READ CAREFULLY
This product should be installed and serviced by a qualified technician, electrician or electrical
maintenance person familiar with its operation and the hazards involved.  Proper installation, which
includes wiring, mounting in proper enclosure, fusing or other overcurrent protection and grounding,
can reduce the chance of electric shocks, fires or explosion in this product or products used with this
product, such as electric 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.  If
information is required on this product, contact our factory.  It is the responsibility of the equipment
manufacturer and individual installer to supply this safety warning to the ultimate user of this product.
(SW effective 11/92)
This control contains electronic Start/Stop and Inhibit circuits that can be used to start and stop
the control.  However, these circuits are never to be used as safety disconnects since they are not
fail-safe.  Use only the AC line for this purpose.
The input circuits of this control (potentiometer, start/stop, Inhibit) are not isolated from AC line.
Be sure to follow all instructions carefully.  Fire and/or electrocution can result due to improper
use of this product.
This product complies with all CE directives pertinent at the time of manufacture.
Contact factory for detailed installation instructions and Declaration of
Conformity.  Installation of a CE approved RFI filter (KBRF-200A, KB P/N 9945A or
equivalent) is required.  Additional shielded motor cable and/or AC line cables may be
required along with a signal isolator (SI-4X, KB P/N 8801 or equivalent).
I.
GENERAL INFORMATION.
The KBRG-213D is a full-wave regenerative control, capable of operating a DC motor
(Permanent Magnet or Shunt) in a bidirectional mode.  It provides 4-quadrant operation which
allows forward and reverse torque in both speed directions.  The drive provides dynamic
response, which closely approximates the performance of servo-type drives.  Ratings and
specifications are presented in tables 1 and 3.  Be sure the drive is used within these ratings
and specifications.  (Note: Regenerative drives normally produce more motor heating
than standard unidirectional SCR speed controls, especially under low speed operation.
This should be taken into consideration when specifying motor rating.)
WARNING!  Be sure to follow all instructions carefully.  Fire or electrocution
can result due to improper use of this product.  Read Safety Warning.

II.
OPERATION.
The KBRG will vary the motor speed as a function of the signal voltage on input terminals “S2"
(signal) and “RB1” (common).  The input voltage can be derived from the wiper of the main
speed potentiometer or from an isolated analog input (voltage following mode).  Since the
KBRG is a 4-quadrant regenerative drive, the motor speed will follow both a positive and
negative signal voltage and drive the motor in both the forward direction and reverse direction.
In addition , it will apply both forward and reverse torque in order to stabilize motor speed.
