INSTALLATION AND OPERATION MANUAL SUPPLEMENT
KBPC-225 (PART NOS. 9391 & 9392)
This supplement is for Model KBPC-225D and is supplied with the KBPC-225 Installation and Operation Manual (Part No. A40350) until the
new manual is available. The manual must be read and understood before operating this drive. For further assistance, contact our Sales
Department at 954-346-4900 or Toll Free at 800-221-6570 (outside Florida).
DESCRIPTION OF PRODUCT UPDATES
● The drive accepts 115 and 208/230 Volt AC Line Input with the setting of both Jumpers J2A and J2B (115V, 230V)
● The drive can be used with 180 and 90 Volt DC motors with the setting of Jumper J3 (180V, 90V).
● A Run Relay has been added, with the output contacts at TB4, which can be used to turn equipment "on" or "off" as a function of drive status
(Off, Stop, Run).
● All trimpots have been moved and aligned at the top of the PC board.
● The drive has been converted to Surface Mount Technology (SMT).
See Figure 4, on other side, for location of Jumpers, Run Relay Output Contacts, and Trimpots (replaces Figure 1, on page 5, in the manual).
Notes: 1. The Schematic (Figure 12, on page 15) and Parts List (Table 4, on page 16) in the manual no longer apply to this drive and should
not be used. 2. The PC board references the motor terminals of Terminal Block TB1 as "A+" and "A-" (the manual references these terminals
as "A1" and "A2") and the field terminals of Terminal Block TB2 as "F+" and "F-" (the manual references these terminals as "F1" and "F2").
DUAL VOLTAGE INPUT SELECTION (JUMPERS J2A and J2B)
Provide selection of AC Line Input voltage (115V, 230V).
See Figure 1.
208/230 Volt AC Line Input: Set both Jumpers J2A and J2B to the "230V"
position (factory setting).
115 Volt AC Line Input: Set both Jumpers J2A and J2B to the "115V"
position.
MOTOR VOLTAGE SELECTION (JUMPER J3) OR
TACH-GENERATOR FEEDBACK SELECTION
(JUMPERS J3 AND J6)
Provides selection of motor voltage (180V, 90V) or tachgenerator feedback voltage (7V, 20/30V, 50V).
180 Volt DC Motors: Set Jumper J3 to the "180V" position
(factory setting).
See Figure 2.
90 Volt DC Motors: Set Jumper J3 to the "90V" position.
See Figure 2.
Step-Down Operation: Set Jumper J3 to the "90V" position
for 90 Volt DC Motors with 208/230Volt AC Line input (with
both Jumpers J2A and J2B set to the "230V" position).
See Figure 2.
Tach-Generator Feedback: With a tach-generator
connected to Terminal block TB3, set Jumper J3 to the "T"
position and set Jumper J6 to the corresponding tachgenerator voltage (factory set to "7V").
See Figure 3.
Note: If tach-generator feedback is not required, the position of Jumper J3 does not matter.

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
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.
3
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.
Standard features include electronic start/stop and an LED indicator array for Power On, Stop
and Overload.
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: Run-Stop-Jog,
and Input Signal Isolation.
