(SW effective 11/92) This control contains electronic start/stop 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. [. . . ] Attach the red wire from the SIVF to the KBVF terminal marked "J3". Attach the orange wire from the SIVF to the KBVF terminal marked "P2". 2. 3. 4 FIGURE 2 ­ SIVF CONNECTION DIAGRAM 5 FIGURE 3 ­ SIVF MOUNTING DIAGRAM (Shown Mounted to Model KBVF-24D) 6 FIGURE 4A ­ SIVF MECHANICAL SPECIFICATIONS (Inches / mm) (Shown Mounted to 1/2HP KBVF ­ With Optional Finger-Safe Cover) 7 FIGURE 4B ­ SIVF MECHANICAL SPECIFICATIONS (inches / mm) (Shown Mounted to 1HP Model KBVF) 8 B. MOUNTING THE SIVF ONTO THE KBVF See figure 3, SIVF Mounting Diagram. See figures 4A and 4B, SIVF Mechanical Specifications, on pages 7 and 8. The SIVF is installed onto the KBVF using (2) two 6-32 X 1/2" screws provided. Note: The screws are a combination head type which allow the use of a readily available #1 or #2 phillips or slotted head screwdriver. Note: Before installing the SIVF be sure the wiring to the KBVF has been completed. See section II, Installation Instructions, on page 3 1. Align the SIVF mounting holes with the tapped holes on the KBVF heat sink and insert the screws through the SIVF mounting holes. Using a screwdriver, fasten both screws until the SIVF is secured to the KBVF (8 in-lbs max). Do not over tighten screws or damage may result to SIVF cover.

CONNECTIONS TO THE SIVF Safety Warning!Do not use FWD-STOP-REV contacts as a safety disconnect since they are not fail-safe. Use only the AC line for this purpose. 9 Note: A connection must be made between FWD and COM or REV and COM in order for control to operate. Jumper shown installed in FWD direction. See Table 2, Terminal Block Wiring Information, on page 9. Note: The MIN and MAX trimpots on the KBVF are non-operational after the SIVF is installed. Signal Following In this mode, a signal source is used to vary motor speed. Voltage Following ­ Uses a voltage source to vary motor speed. Figure 5 ­ Voltage Following Connection (Jumper J1 in "VOLT" Position) Set J1 to "VOLT" position and connect the voltage source to TB1 terminals SIG (+) and COM (-). See figure 5, Voltage Following Connection. Be sure the positive (+) signal is connected to "SIG" terminal and the negative (-) is connected to the "COM" terminal. When a 0V DC signal is applied, the motor will operate at the minimum set speed (set by the MIN trimpot on the SIVF). [. . . ] Before installing the finger-safe cover onto the KBVF, connect orange wire, red wire and 3-pin connector to KBVF. Install SIVF onto KBVF before installing the finger-safe cover (see section II, on page 4). Install the finger safe cover onto the KBVF using the four (4) retaining clips. 15 FIGURE 11 ­ FINGER-SAFE COVER 16 ­ NOTES ­ 17 V.
