This document is supplied with Signal Isolator SIMG only.

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. A40269). Refer to the SIMG Installation and Operating Instructions Manual for specific and external signal following connections. See Figures 1 - 4, on page 2.

Tools required for installation: small flat blade screwdriver and long nose pliers.

Notes: 1. To install the SIMG, be sure the Top Panel of the KBMG 2-Piece Finger-Safe Cover (FSC) is not installed. 2. All trimpots and jumpers, on the KBMG, must be set before installing the SIMG.

1Preparing the KBMG Prior to Installing the SIMG - See Figure 1.

1.1Insert the flat blade screwdriver between the KBMG PC Board and Terminal Block TB1 and gently pry it off. Discard the Terminal Block.

Note: When prying off Terminal Block TB1, care should be taken to not scratch circuit traces that are on the PC Board surface.

1.2Using a flat blade (or Phillips) screwdriver, remove the screw from the KBMG FSC. Retain this screw for use in Section 2.3, below.

1.3Using long nose pliers, remove and discard the Terminal Boots that are factory installed on Terminals "F-" and "F+" on the KBMG.

2Installing the SIMG onto the KBMG - See Figure 2.

2.1Align and gently push the Terminal Block on the SIMG onto the Terminal Block Header on the KBMG.

2.2Align the (3) Holes on the SIMG with the (3) Snap Posts on the KBMG FSC. Gently press the SIMG Board onto the (3) Snap Posts. Apply pressure at each Snap Post.

2.3Install the Screw, that was removed in Section 1.2, above, and gently tighten it to secure the SIMG onto the KBMG FSC. Do not overtighten.

3Wiring the SIMG After Installed onto the KBMG - See Figures 3 and 4.

Note: On older SIMG models, the Brown and Yellow Wires had to be crisscrossed. On this SIMG model, the Brown and Yellow Wires are not crisscrossed. See Figures 2 and 3.

3.1Carefully insert the Brown and Yellow Wires through the Retainer Clip on the KBMG FSC.

3.2Connect the Brown Wire (larger terminal) to Terminal "F-" on the KBMG.

3.3Connect the Yellow Wire (smaller terminal) to Terminal "F+" on the KBMG.

4Installing the SIMG Finger-Safe Cover - See Figure 2.

Align the (4) Snap Tabs on the SIMG FSC with the (4) slots on the KBMG FSC. The Cable Shroud must be positioned over the Brown and Yellow Wires. Apply pressure to snap the cover into position.

Note: Be sure that the Brown and Yellow Wires are centered in the Retaining Clip so the wires are not damaged by the Cable Shroud.

The SIMG installation is now complete.

I.INTRODUCTION

Thank you for purchasing the SIMG Bipolar Signal Isolator (P/N 8832). KB Electronics, Inc. is committed to providing total customer satisfaction by producing quality products that are easy to install and operate. The SIMG is manufactured with surface mount components incorporating advanced circuitry and technology.

The SIMG provides input isolation and is used to isolate, amplify, and condition DC voltage signals from any external source (power supplies, motors, tachometer generators, transducers, and potentiometers). The isolated output voltage of the SIMG provides input signals to the KBMG-212D (hereinafter referred to as KBMG) Regenerative Drive (P/N 8831). In also provides isolation for motor direction switching and an isolated power supply for transducer or potentiometer operation. The PWR LED provides indication that power is applied.

All input connections (+15, -15, SIG, COM, and EN) are made via a barrier terminal block and are isolated from AC line and motor wiring.

The SIMG is factory calibrated to accept a signal input voltage of -10V to +10V DC. OFFSET and MAX trimpots are provided in order to recalibrate the SIMG for specific applications.
