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 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 potentiometer circuit (P1, P2, P3) of this control is 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 9945C 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).
Special Instruction for Cycle on Demand Applications
The camshaft of the Index drive should be in the middle of its dwell position. This is the position
in which the motor should receive its signal to start. Connect the normally closed side of the cycling
limit switch (LS1) to the control's TB3 terminals STOP (4) and RTN (3). Note: See fig. 14, p. 15
for information regarding the correct dwell position and cycling cam lobe positions.
I. GENERAL INFORMATION.
The KBPI INDEXER controls are packaged in a NEMA 4X enclosure which is ruggedly
constructed of die cast aluminum. The controls are designed specifically for cycling and
indexing applications. A variety of models provide different features and input voltage ratings
(see table 1, p. 3). The controls provide the user with isolated logic functions: STOP, JOG
and RUN. Other functions, such as cycle on demand, can easily be obtained. An important
feature of the control is jumper J1 which is used for DC current selection. It automatically
presets the IR Compensation and Current Limit for safe operation on various motors.
Standard features include built-in armature fusing and an LED indicator array for "power on,"
"stop" and "overload." Part Number 8501 also contain logic input for "Reverse Run" and
"Reverse Jog." The controls contain trimpots that can be used to readjust Minimum and
Maximum speed, Current Limit and IR Compensation. The front panel contains a built-in 5K
ohm speed potentiometer and a Run, Jog/Stop switch. (See table 3, p. 7 for selectable jumper
information.)
