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-200, KB P/N 9945 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).
ii. KBPC-225 SIMPLIFIED OPERATING INSTRUCTIONS
IMPORTANT – You must read these simplified operating instructions before you proceed. 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 before proceeding.
1. Connections.
A. AC Line. Wire AC line voltage (230 VAC - 50/60 Hz) to terminals L1 and L2. Connect ground
wire (earth) to Green Screw on case.
B. Motor.
a. Permanent Magnet (PM) Type: Connect motor armature leads to terminals A1(+) and
A2( – ).
b. Shunt Wound Motors: Connect motor armature as above. Connect full voltage shunt field
wires (180 volt motors with 200 volt fields) to F1 and F2. Connect half voltage field wires
(180 volt motors with 100 volt fields) to F1 and L1.
2. Speed or Torque Mode – Jumper J1 is factory set for speed control operation ("SPD"). For
torque control, set J1 to "TRQ" position.
3. Trimpot Settings – All trimpots have been factory set in accordance with Fig. 1 and Table 2.
4. Diagnostic LEDs – After power is turned on, observe LEDs to verify proper control function.
5. Fusing – Install 25 amp - 250 VAC fuses in both the AC Line and armature leads. See Section
VI (p. 10, 11).
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.
