Warning!Before installing the SIMG onto the KBMG, the AC power must be disconnected. The following Installation and Wiring instructions are to be used as a supplement to the SIMG Installation and Operating Instructions Manual (Part No. Refer to the SIMG Installation and Operating Instructions Manual for specific and external signal following connections. Tools required for installation: small flat blade screwdriver and long nose pliers. [. . . ] Note: This figure is also supplied as a separate drawing. ! Warning!Make sure all power is disconnected from the KBMG before proceeding. A. Removing the KBMG Finger-Safe Cover If a finger-safe cover is not installed on the KBMG, proceed to section IIC (Modifying the KBMG Finger-Safe cover). If a finger-safe cover is installed on the KBMG, remove the two (2) socket head 5-40 X 5/16" screws located at the rear of the KBMG using the supplied 3/32" hex key. Also, remove the two (2) 6-32 X 1-3/4" screws located on either side of terminal block TB1. See figure 4 on page 8. 6 FIGURE 3 ­ KBMG/SIMG ASSEMBLY DIAGRAM B. Removing Terminal Block TB1 from the KBMG Remove terminal block TB1 from SIMG Finger-Safe Cover the KBMG by rocking it back and forth or using a screwdriver to gently pry it off. The removed terminal block (4 places) TB1 will not be used and may be discarded. C. Modifying the KBMG Finger6-32 x 1-3/4" Screws Safe Cover (2 places) Once the KBMG finger-safe cover is removed, it has to be modified to accommodate the SIMG. Cut out the finger-safe cover panel Cable at seven (7) places as Assembly shown in figure 6 on page Note: 9. (Note: Some fingerYellow to F+ safe covers may already Brown to Fhave the panel removed. ) To access the field termi5-40 x 5/16" nals (F+ and F- on the Screws KBMG) cut out the field (2 places) tab of the KBMG fingersafe cover at three (3) places as shown in figure 7 on page 9. SIMG KBMG Finger-Safe Cover KBMG 7 D. Installing the KBMG FingerSafe Cover Once the KBMG finger-safe cover has been modified, it can be installed onto the KBMG. Note: It is recommended that these wires be twisted at least three (3) times to help reduce noise. FIGURE 9 ­ INSTALLING FIELD CONNECTOR 11 III. Connections to the SIMG 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: SIMG Enable jumper J1 must be installed, or a connection must be made between EN and COM terminals of SIMG TB1 in order for the KBMG to operate.

Voltage Following ­ Uses a voltage source to vary motor speed. Connect the voltage source to TB1 terminals SIG and COM. When a 0V DC signal is applied, the control will operate at the minimum set speed (set by the OFFSET trimpot on the SIMG). When a 10V DC signal is applied, the motor will operate at the maximum set speed (set by the MAX trimpot on the SIMG).

[. . . ] Motor Field Connection If a shunt wound motor is used, the motor field wires connect to F+ and F- terminals on the SIMG. To access these terminals, cut out the field tab of the SIMG finger-safe cover at three (3) places as shown in figure 14 on page 17. 16 TB1 FIGURE 14 ­ REMOVING THE SIMG FINGER-SAFE COVER FIELD TAB SIMG Finger-Safe Cover Cut Out Tab (3 Places) to Access Field Terminals. (For Shunt Wound Motors Only. ) 17 IV. CALIBRATION PROCEDURE (See Safety Warning, on page 1) The SIMG is factory calibrated, but readjustments to the OFFSET and MAX trimpots can be made to customize for a particular signal input requirement.
