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 explosions 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 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.

I. OPERATION.

The APRM®-PC provides anti-plug instant reverse and solid state dynamic braking. It has been specifically designed for installation into the KBPC-240D speed control. The patented circuitry senses armature voltage and permits armature switching to take place only when current levels are near zero. This eliminates contact arcing normally associated with relay reversing circuits.

Braking is achieved via an electronic circuit utilizing an SCR and brake resistor. An LED indicates when the APRM® is in the brake mode. Operation is made via a SPDT switch with

Switch Position Switch Connection

Forward (FWD) S1, S2 + -

Brake (BRK) None (Center off)* 0 0

Reverse (REV) S2, S3 - +

*Note: If no connection is made to S1, S2 and S3, the APRM® is in the brake

mode which will rapidly stop the motor.

center off. The unit installs easily into the inside cover of the KBPC control. Wiring is made via quick-connect terminals.

II. SET UP.

Be sure the Jumpers J1 and J2 on the APRM® are both set to the proper AC line input voltage, 115 or 230VAC. Note: This should be the same setting as the Jumpers J2A and J2B are set for on the KBPC main board which should correspond to the correct AC line input voltage. Refer to the KBPC-240D Installation and Operating Instruction Manual for complete information.
