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 explosion 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 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. Use only the AC line for this purpose. 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. 1 FIGURE 1 ­ CONTROL LAYOUT 2 I. INTRODUCTION Thank you for purchasing the SIVF Signal Isolator (P/N 9474). KB Electronics, Inc. is committed to providing total customer satisfaction by producing high quality products that have been manufactured to the highest standards and techniques in the industry. The SIVF is engineered with state-of-the-art surface mount technology (SMT) incorporating advanced circuitry in a relatively small and user friendly package, making it convenient to operate and easy to install. The SIVF is used to isolate, amplify, and condition DC voltage and current signals from any source (power supplies, motors, tachometer generators, transducers, and potentiometers). The isolated output voltage of the SIVF provides input signals to all models of the KBVF Adjustable Frequency Drive (P/N 9957, 9958, 9959, 9977, 9978, and 9979). Signal input and motor direction control is performed by making connections to the on-board barrier terminal. All inputs (+5V, SIG, COM, FWD & REV) to the SIVF are isolated from the AC line and motor connections. The SIVF is factory calibrated to accept signal input voltage (0 ­ 5V DC), current (4 ­ 20mA DC), or a potentiometer (5K) via a jumper selection. MIN and MAX trimpots are provided in order to readjust the SIVF. This allows the use of 0 ­ 2.5 thru 25V DC input voltage signals for customizing specific applications. 3 TABLE 1 ­ GENERAL PERFORMANCE SPECIFICATIONS Voltage Following Operation Input Range (V DC) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 ­ 2.5 thru 25 Current Following Operation Input Range (mA DC) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 ­ 20 Potentiometer Operation (K) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Output Voltage at P2 (V DC) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 ­ 5 MIN Trimpot Range (with 0 Volts Input) (% Full Speed) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 ­ 40 MAX Trimpot Range (with 5 Volts Input) (% Full Speed) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 70 ­ 110 FWD and REV Input Switch Types . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Addendum I on page 15. II. INSTALLATION INSTRUCTIONS WARNING: HIGH VOLTAGE IS PRESENT WHILE LEDs ARE ILLUMINATED. Before wiring the SIVF to the KBVF, disconnect all power to the KBVF and wait until "PWR" and "ST" LEDs are no longer illuminated. A. Wiring the SIVF to the KBVF ­ (Note: Do not install the SIVF to the KBVF until wiring is completed.) 1. Remove the F-S-R jumper which is installed on CONN2 of the KBVF. Attach the 3-pin connector (with white, black, and red wires) from the SIVF to the KBVF connector marked "CONN2". 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. 2. 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. A. Signal Following In this mode, a signal source is used to vary motor speed. i. 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). When a 5V DC signal is applied, the motor will operate at the maximum set speed (set by the MAX trimpot on the SIVF). ii. Current Following ­ Uses a current source to vary motor speed. 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. 10 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). See figure 7 Potentiometer Connection. 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). When the potentiometer is set to 100% (full clockwise position) the motor will operate at full speed (set by the MAX trimpot on the SIVF). C. Unidirectional Operation To operate the control in forward, install a jumper between "FWD" and "COM" terminals of the SIVF To operate the control in reverse, install a jumper between "REV" and "COM" termi11 nals of the SIVF. See figure 8, Unidirectional Operation. Note: A SPDT switch or contact can be used as an enable to turn control on and off electronically. Figure 8 ­ Unidirectional Operation 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. D. Bidirectional Operation i.
