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. 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). TABLE 2 TERMINAL BLOCK WIRING INFORMATION

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.

Note: A connection must be made between FWD and COM or REV and COM in order for control to operate. 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 (-). 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). When a 5V DC signal is applied, the motor will operate at the maximum set speed (set by the MAX trimpot on the SIVF). Set J1 to "CUR" position and connect the current source to TB1 terminals SIG (+) and COM (-). See figure 7, Current Following Connection, on page 11.

Be sure the positive (+) signal is connected to "SIG" terminal and the negative (-) is connected to the "COM" terminal.
Figure 6 Current Following Connection (Jumper J1 in "CUR" Position)
When a 4mA DC signal is applied, the motor will operate at the minimum set speed (set by the MIN trimpot on the SIVF). When a 20mA DC signal is applied, the motor will operate at the maximum set speed (set by the MAX trimpot on the SIVF) B. Potentiometer Operation Uses a potentiometer to vary motor speed. Set J1 to "VOLT" position and connect the 5K potentiometer to TB1 terminals marked "SIG" (wiper of Figure 7 Potentiometer Connection potentiometer), "+5" (high side of poten(Jumper J1 in "VOLT" Position) tiometer), and "COM" (low side of potentiometer). When the potentiometer is set to 0% (fully counterclockwise), 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.
