ii. 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 (KBSI-240D, KB P/N 9431 or equivalent).
I. GENERAL INFORMATION.
The KBPC Series Nema 4 X (IP-65) is a unidirectional SCR DC Motor Speed and Torque Control
designed for applications requiring watertight integrity, including washdown. Its housing is
ruggedly constructed of die cast aluminum, protected with an acrylic coating that provides
excellent corrosion resistance. All switches are sealed with rubber boots and the main speed
potentiometer contains a shaft seal.
The electronics for the KBPC is state-of-the-art and includes short circuit and transient protection
which provides the ultimate in reliability. Electronic overload protection prevents motor burnout
and demagnetization of PM motors. The control can be operated in either the Speed or Torque
mode via jumper selection. The current range, which is also jumper selectable, eliminates the
necessity for calibration of IR Compensation and Current Limit for most applications. The KBPC
also contains jumper selections for AC line voltage (230/115), DC armature voltage (180/90) and
feedback type (armature/Tach-generator).
Standard features include armature fusing*, electronic start/stop and an LED indicator array for
Power On, Stop and Overload (*fuse supplied separately).
Although the KBPC is factory set for most applications, a variety of trimpots allow adjustment of
the following parameters: Minimum and Maximum Speed, Acceleration, Deceleration, Current
Limit, IR Comp, and Timed Current Limit. Optional features offered are: On/Off AC Line Switch,
Forward-Brake-Reverse, Run-Stop-Jog, Input Signal Isolation, RFI Filtering, and Electronic Run-
Brake Module.
WARNING! Be sure to follow all instructions carefully. Fire or electrocution
can result due to improper use of this product. Read Safety Warning.
