User manual KB ELECTRONICS KBMD-240D

[. . . ] Tools required for installation: small flat blade screwdriver, long nose pliers, cutters. To install the SIMG, be sure the Top Panel of the KBMD-240D 2-Piece Finger-Safe Cover (FSC) is not installed. All trimpots and jumpers, on the KBMD-240D, must be set before installing the SIMG. 1 Preparing the KBMD-240D Prior to Installing the SIMG - See Figure 1. [. . . ] However, speed range may be reduced and motor derating may be required. 10 D. J4 ­ Analog Input Voltage ­ Jumper J4 is set to the "15V" position for potentiometer operation. If the control is to be operated from an isolated 0 ­ ±10VDC signal (see sec. 22. ), set J4 to the "10V" position. J5 ­ Control Mode (Speed or Torque). FIG. 3 ­ JUMPER J4 SETTING Potentiometer Operation Signal Following FIG. Speed (SPD) Mode ­ (Note: Factory setting of J5 is Speed Mode Torque Mode Speed mode. ) In the speed control mode (J5 set to SPD), the KBMD-240D-212D will provide variable speed control. The motor speed will be in direct proportion to the input signal. Both forward and reverse torque are used to stabilize motor speed. Torque (TRQ) Mode ­ In the torque control mode (J5 set to TRQ), the KBMD-240D-212D will vary the maximum motor torque as a function of the voltage input to terminals "SIG" (signal) and "COM" (common). This voltage can be derived from the wiper of the main potentiometer or from an isolated analog input (signal voltage following). 8 ­ AC LINE CONNECTION Code requirements and other local codes that apply. A "normal blo" 20 amp fuse or circuit breaker should be used on each AC line conductor that is not at ground potential (do not fuse neutral or grounded conductors). 24 for fuse information. ) Wire control in accordance with connection diagrams (see figures 8, 9, 10A, 10B, 11 and 14 on pages 16, 17, 19 and 22). A separate AC line switch or contactor must be wired as a disconnect switch so that contacts open each ungrounded conductor of the control. See table 6 for terminal block wiring information. AC Line ­ Connect AC Line to terminals L1 and L2. (Be sure jumpers J1A and J1B are set to match the AC line voltage used. ) (See table 5, p. Ground ­ Be sure to ground (earth) control via green screw located on chassis. Motor Armature ­ Connect motor armature to terminals M1 (+) and M2 (­). (Be sure jumper J3 is set to match motor voltage. ) (See table 5, p. Field ­ For Shunt Wound motors only. [. . . ] Adjusting the CL above 150% of motor rating can cause overheating and demagnetization of some PM motors. IR Compensation (IR Comp) ­ The IR Comp is used to stabilize motor speed under varying loads. Readjust the IR Comp trimpot as follows: i. Initially set trimpot to factory position (approximately 10 o'clock). [. . . ]
