I. INTRODUCTION
Thank you or purchasing the SIMG Bipolar Signal Isolator (P/N 8832). KB
Electronics, Inc. is committed to providing total customer satis action by pro-
ducing quality products that are easy to install and operate. The SIMG is
manu actured with sur ace mount components incorporating advanced cir-
cuitry and technology.
The SIMG provides input isolation and is used to isolate, ampli y, and condi-
tion DC voltage signals rom any external source (power supplies, motors,
tachometer generators, transducers, and potentiometers). The isolated out-
put voltage o the SIMG provides input signals to the KBMG-212D (here-
ina ter re erred to as KBMG) Regenerative Drive (P/N 8831). In also pro-
vides isolation or motor direction switching and an isolated power supply or
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 rom AC line and motor wiring.
The SIMG is actory calibrated to accept a signal input voltage o -10V to
+10V DC. OFFSET and MAX trimpots are provided in order to recalibrate the
SIMG or speci ic applications.

F. iring the SIMG to the KBMG
See igure 8 on page 10.
The SIMG is powered rom the KBMG with a connector that is installed rom the
SIMG CON2 to the KBMG F+ and F- terminals. The yellow wire connects to the
KBMG F+ terminal and the brown wire connects to the KBMG F- terminal. When the
ield connector is properly installed the wires should cross over each other. See ig-
ure 9. I the connector is wired incorrectly, the SIMG PWR LED will not illuminate
and the control will not operate. Note: It is recommended that these wires be twist-
ed at least three (3) times to help reduce noise.

III. Connections to the SIMG
Safety arning! Do not use F D-STOP-REV contacts as a safety discon-
nect 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.
A. Voltage Following – Uses a
voltage source to vary motor
speed. See igure 10. Connect
the voltage source to TB1 ter-
minals SIG and COM. When a
0V DC signal is applied, the
control will operate at the mini-
mum 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).
Applying a positive (+) signal to SIG terminal, with respect to COM terminal, will oper-
ate the motor in the orward direction.

B. Signal Following from
Armature Voltage – Uses
motor armature voltage as a
signal input. I the signal input
voltage applied to the SIMG is
derived rom a motor armature
voltage output, it is necessary
to install a 1/4W resistor in
series with the signal lead into
the SIMG. For a 90V DC
motor, install a 150K resistor.
or a 180V DC motor, install a
330K resistor.
C. Unidirectional Potentiometer
Operation (Forward) – Uses a
potentiometer to vary motor speed.
See igure 11A on page 13.
Connect the 5K potentiometer to
TB1 terminals marked “SIG” (wiper
o potentiometer), “+15V” (high side
o potentiometer), and “COM” (low
side o potentiometer). Use the
potentiometer to vary motor speed.
I the motor is not running in the
desired direction, either reconnect
the high side o the potentiometer to TB1 terminal marked “-15V” or reverse the
motor leads.

D. Unidirectional Potentiometer Operation (Reverse) – Uses a potentiometer to vary
motor speed. See igure 11B on page 13. Connect the 5K potentiometer to TB1 ter-
minals marked “SIG” (wiper o potentiometer), “-15V” (high side o potentiometer),
and “COM” (low side o potentiometer). Use the potentiometer to vary motor speed
and the switching device to select motor direction. I the motor is not running in the
desired direction, either reconnect the high side o the potentiometer to TB1 terminal
marked “+15V” or reverse the motor leads.
E. Bidirectional Potentiometer Operation – Uses a potentiometer to vary motor
speed and direction. See igure 11C on page 13. Connect the 5K potentiometer to
TB1 terminals marked “SIG” (wiper o potentiometer), “+15V” (high side o poten-
tiometer), and “-15V” (low side o potentiometer). Use the potentiometer to vary
motor speed and direction.
When the potentiometer is in the center position, the control output can be set to
zero, using the OFFSET trimpot. Rotating the trimpot clockwise will cause the motor
to rotate in the orward direction. Rotating the potentiometer counterclockwise will
cause the motor to rotate in the reverse direction.
F. Unidirectional Potentiometer with Reversing Contacts – Uses a potentiometer to
vary motor speed. See igure 11D on page 13. Connect the 5K potentiometer to TB1
terminals marked “SIG” (wiper o potentiometer), “+15V” (high side o potentiometer),
and “COM” (low side o potentiometer). Use the potentiometer to vary motor speed
and the switching device to select motor direction. When the potentiometer is set to
0% ( ully counterclockwise), the motor will operate at the minimum set speed (set by
the OFFSET trimpot on the SIMG). When the potentiometer is set to 100% ( ully
clockwise) the motor will operate at ull speed (set by the MAX trimpot on the SIMG).

G. Enable Switch Connection
Safety arning! Do
not use Enable or
Start/Stop contacts as a sa ety
disconnect since they are not
ail-sa e. Use only the AC line
or this purpose. See igure 13.
I a Start/Stop unction is
required, remove SIMG Enable
jumper J1 and wire a switch to
EN and COM terminals o
SIMG TB1. When the switch is
opened, the control will stop.
When the switch is closed, the
control will operate.
H. Tachometer Generator Connection
See igure 8 on page 10. To wire a 7V or 50V per 1000RPM tachometer generator
to the SIMG, connect the positive (+) side o the tachometer generator to terminal
“T2” and the negative (-) side o the tachometer generator to terminal “T1“ o the
SIMG. Note: I the positive (+) and negative (-) tachometer generator connections
are not connected as described above, the motor will run at ull speed only.
I. Motor Field Connection
I a shunt wound motor is used, the motor ield wires connect to F+ and F- terminals
on the SIMG. To access these terminals, cut out the ield tab o the SIMG inger-sa e
cover at three (3) places as shown in igure 14 on page 17.
