See back cover TABLE OF CONTENTS Section i. [. . . ] Jumper J4 must be in "7V" position for 7 Volt per 1000 RPM tach-generators or "50V" position for 50 Volt per 1000 RPM tach-generators. Note: When using a tach-generator, the IR trimpot should be set fully counterclockwise. IV. SETTING SELECTABLE JUMPERS The KBPW-240D has customer selectable jumpers which must be set before the control can be used. See Figure 1, on page 4 for location of jumpers. Motor Voltage Selection (J1) ­ Jumper J1 is factory set to "90V" position for 90 Volt SCR rated motors (or 130 Volt PWM rated motors). For 180 Volt SCR rated motors (or 220 Volt PWM rated motors), set jumper J1 to "180V" position. Note: If jumper J1 is set to "T" position, a tach-generator must be wired to TB3. If a tach-generator is not used, jumper J1 must be in either "90V" or "180V" position. If jumper J1 is in "T" position and a tach-generator is not used, the motor will accelerate to full speed and the main speed potentiometer will not control speed. Motor Current Selection (J2) ­ Jumper J2 is factory set to "7. 5A" position for 7. 5 Amp motors. For motors of lower amperage, set Jumper J2 to the corresponding position for the motor being used. Note: For low (L) motor current settings (0. 8A, 0. 5A, 0. 4A, 0. 3A, and 0. 2A), it is necessary to remove resistor R35. Cut the leads at the locations shown in Figure 16.

Timed and Non-Timed Current Limit Selection (J3) ­ Jumper J3 is factory set to "TCL" position for timed current limiting operation. For non-timed current limiting operation, set jumper J3 to "NTCL" position. TCL (Timed Current Limit) ­ When Jumper J3 is in the "TCL" position, the control will go into "STOP" after it is in overload for a predetermined amount of time (set by the TCL trimpot). FIGURE 17 ­ CURRENT LIMIT MODE SELECTION J3 Set for TCL Mode (Timed Current Limit) (Factory Setting) J3 Set for NTCL Mode (Non-Timed Current Limit) J3 TCL NTCL J3 TCL NTCL Resetting the Control After TCL ­ To reset the control after it has gone into TCL, momentarily set the Start/Stop switch to "START" position or disconnect and reconnect the AC line. If an On/Off AC Line Switch is installed, set it to "OFF" position and then back to "ON" position. If the Start switch is jumpered (START and COM terminals connected), the control must be restarted by disconnecting and reconnecting the AC line. NTCL (Non-Timed Current Limit) ­ When jumper J3 is set to "NTCL" position, the control will not go into "STOP" after it is in overload. Note: TCL trimpot will have no affect when jumper J3 is in "NTCL" position. [. . . ] Mounts on the enclosure cover and is supplied with a switch seal to maintain watertight integrity. Run-Stop-Jog Switch (P/N 9340) ­ Selects speed setting from either main potentiometer or JOG trimpot. Mounts on the enclosure cover and is supplied with a switch seal to maintain watertight integrity. Signal Isolator KBSI-240D (P/N 9431) ­ Provides isolation from non-isolated signal sources. [. . . ]
