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.

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

1.1 Insert the flat blade screwdriver between theKBMG 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.

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

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

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

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

2.2 Align 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.

2.3 Install 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.

3 Wiring 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.

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

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

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

4 Installing 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. SAFETY WARNING! Please read carefully:

Be sure to follow all instructions carefully. Fire and/or electrocution can result due to
improper use of this product.

This product should be installed and serviced by a qualified technician, electrician, or
electrical maintenance person familiar with its operation and the hazard involved. Proper
installation, which includes wiring, mounting in proper enclosure, fusing or other over cur­rent 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 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 and enable 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.

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.
