KBPC-240D (Part Nos. 9338 and 9342) Installation and Operation Manual Supplement
This supplement is for Model KBPC-240D Installation and Operation Manual (Part No. A40400) 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).
This drive has been converted to Surface Mount Technology (SMT). All trimpots have been moved and aligned at the top of the PC board.
A Run Relay has been added, which can be used to turn equipment "on" or "off" as a function of drive status (Off, Stop, Run). The General
Performance Specifications, Electrical Ratings, Mechanical Specifications, and Connection Diagrams have not changed. The Parts List (Table
11, on pages 17 and 18) and Schematic (Figure 16, on page 19) in the manual no longer apply to this drive and should not be used. See
Figure 1 for the location of the Run Relay Output Contacts, Trimpots, and Jumpers (replaces Figure 1, on page 3, in the manual). See Figure
1 for the Run Relay Output Contacts ratings. See Table 1 for the drive operating conditions and Run Relay Output Contacts status.

  • Page 26: Mechanical Specifications

    INTRODUCTION The KBSI-240D Signal Isolator is used to isolate, amplify and condition DC voltage and current signals from any source (motors, tachs and transducers) which will drive most variable speed motor controls with a voltage following input. The maximum output voltage of the isolator is 10 volts, which is a linear function of the input signal.
