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.

III. Connections to the SIMG

Safety Warning! Do not use FWD-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 figure 10. 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).

Applying a positive (+) signal to SIG terminal, with respect to COM terminal, will oper­ate the motor in the forward direction.

B. Signal Following from

Armature Voltage – Uses

motor armature voltage as a
signal input. If the signal input
voltage applied to the SIMG is
derived from 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.
for a 180V DC motor, install a
330K resistor.

C. Unidirectional Potentiometer

Operation (Forward) – Uses a

potentiometer to vary motor speed.
See figure 11A on page 13.
Connect the 5K potentiometer to
TB1 terminals marked “SIG” (wiper
of potentiometer), “+15V” (high side
of potentiometer), and “COM” (low
side of potentiometer). Use the
potentiometer to vary motor speed.
If the motor is not running in the
desired direction, either reconnect
the high side of 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 figure 11B on page 13. Connect the 5K potentiometer to TB1 ter­minals marked “SIG” (wiper of potentiometer), “-15V” (high side of potentiometer),
and “COM” (low side of potentiometer). Use the potentiometer to vary motor speed
and the switching device to select motor direction. If the motor is not running in the
desired direction, either reconnect the high side of 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 figure 11C on page 13. Connect the 5K potentiometer to
TB1 terminals marked “SIG” (wiper of potentiometer), “+15V” (high side of poten­tiometer), and “-15V” (low side of 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 forward 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 figure 11D on page 13. Connect the 5K potentiometer to TB1
terminals marked “SIG” (wiper of potentiometer), “+15V” (high side of potentiometer),
and “COM” (low side of potentiometer). Use the potentiometer to vary motor speed
and the switching device to select motor direction. When the potentiometer is set to
0% (fully 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% (fully
clockwise) the motor will operate at full speed (set by the MAX trimpot on the SIMG).

15

G. Enable Switch Connection

Safety Warning!

Do

not use Enable or
Start/Stop contacts as a safety
disconnect since they are not
fail-safe. Use only the AC line
for this purpose. See figure 13.

If a Start/Stop function is
required, remove SIMG Enable
jumper J1 and wire a switch to
EN and COM terminals of
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 figure 8 on page 10. To wire a 7V or 50V per 1000RPM tachometer generator
to the SIMG, connect the positive (+) side of the tachometer generator to terminal
“T2” and the negative (-) side of the tachometer generator to terminal “T1“ of the
SIMG.

Note: If the positive (+) and negative (-) tachometer generator connections

are not connected as described above, the motor will run at full speed only.

I. 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.
