[. . . ] INSTALLATION AND OPERATING INSTRUCTIONS MODEL KBPC-240D KB Part No. 9342 (White Case) NEMA 4X, IP-65 SCR Speed and Torque Control Designed For DC Motors Rated 1/50 ­ 1 HP @ 90VDC, 1/25 ­ 2 HP @ 180VDC TM This control will not operate without installing the correct armature fuse ­ supplied separately. Note: Product illustration is shown with optional ForwardBrake-Reverse and Run-Jog options. TM See Page 2 See Safety Warning on Page 2 The information contained in this manual is intended to be accurate. However, the manufacturer retains the right to make changes in design which may not be included herein. TM A COMPLETE LINE OF MOTOR DRIVES © 1998 KB Electronics, Inc. TABLE OF CONTENTS Section Page i. KBPC-240D Simplified Operating Instructions . [. . . ] (Be sure jumper J3 is set to closely match motor voltage. Do not wire switches or relays in series with the armature. Armature switching can cause catastrophic failure of motor and/or control. Do not bundle AC and motor wires with other wires (e. g. , potentiometer, analog input, ForwardBrake-Reverse, etc. ). 8 ­ CONNECTION DIAGRAM TABLE 8 ­ RELATIONSHIP of AC LINE INPUT AND MOTOR VOLTAGE with J2 and J3 JUMPER POSITION AC INPUT VOLTAGE 115 230 230 J2A, J2B POSITION 115 230 230 J4 POSITION 90 180 90* MOTOR VOLTAGE 90 180 90* *A 90VDC motor can be used with a 230VAC line. However, speed range may be reduced and motor derating may be required. Field ­ For Shunt Wound Motors Only. Do not use terminals F1 and F2 for any other purpose than to power the field on a shunt wound motor. Connect motor shunt field to terminals F1 and F2 for 90VDC motors with 100VDC fields and 180VDC motors with 200VDC fields. For motors with half voltage fields, 90VDC motors with 50VDC fields and 180VDC motors with 100VDC fields, connect field to terminals F1 and L1. See table 9 for summary of Field Connections. See figures 9A and 9B for field wiring diagrams. CAUTION ­ Shunt-Wound motors may be damaged if field remains powered without motor rotating for an extended period of time.

Ground ­ Be sure to ground (earth) the control by connecting a ground wire to the Green Ground Screw located to the right of the terminal block. 10 ­ TACH-GENERATOR CONNECTION DIAGRAM E. DC Tach-generator Input ­ If tachgenerator feedback is required, an analog tach signal must be connected to the terminal block TB3. (Note: For tachgenerator feedback Jumper J3 must be set to the "T" position, jumper J6 must be set for the proper tach voltage, and the IR COMP must be set to minimum (ccw) position. ) (See section II F, p. 9. ) Connect the tachgenerator so that when the motor rotates the positive tach voltage lead is connected to T+ and the negative tach lead is connected to T­ (See figure 10). 11 Note: If the tach voltage is connected backwards, the control will drive the motor at full speed only. Note: If the Forward-Brake-Reverse switch is used, provision must be made to reverse the polarity of the tach-generator leads when the control is switched to "Reverse. " Warning!To avoid erratic operation do not bundle AC Line and motor wires with potentiometer, voltage following, enable, inhibit or other signal wiring. Use shielded cables on all signal wiring over 12" (30 cm) ­ Do not ground shield. [. . . ] The installation is made simple with the use of quick-connect terminals. Note: Signal Isolator (P/N 9431) cannot be installed with Foward-Brake-Reverse Switch. Signal Isolator (Model KBSI-240D, P/N 9431) ­ Signal isolation is required when a remote nonisolated analog signal is to be used. Provision is made to install Model KBSI240D on 4 bosses inside the front cover. [. . . ]
