DESCRIPTI0 N
The Statotrol
II drive is a lligh performance
full wave
DC drive.
The regulating
function
is provided
by a custom integrated
circuit.
The electronic
eomponents are protected
by a rugged NEMA 4 enclosure,
The motor is either a shunt wound or permanent
magnet field DC motor specially
designed for use with a
full wave phase controlled
SCR power supply.
As soon as the equipment
is received,
it should be
unpacked and examined for any damage sustained
in
transit.
If damage is evident, a damage claim should
be filedimmediately with the transportation
company,
and the local General Electric
Co. Sales Office should
be promptly
notified.
If the equipment
is not to be used as soon as it is unpacked,
it should be stored in a clean,
dry place and
protected
against accidental
damage.
Avoid storage
in a location where construction
work is in progress.
IN STA LLATIO N
INSTALL
Standard
features
of the Statotrol
II drive include
speed control, protective
current limit, undervoltage
protection,
and potentiometer
adjustments
for positive
and negative IR compensation,
maximum speed, mtnimum speed,
and torque taper.
Optional features
include dynamic braking, controlled torque plug reverslng, adjustable
torque control,
adjustable
linear timed
acceleration
and deceleration,
tach feedback, instrument follower,
tach follower,
speed indication,
regenerative
braking, and a variety of special functions,
CONTROL
STATION
AND OPTIONS
Either a local control station or a remote control
station adapter unit must be attached to the main cornponent board before operation is possible.
Refer to
Figure 2 for the mounting location and orientation
of
the control station.
If the reversing
option is to be
used, it should be plugged in before the control station is mounted.
When installing the control station,
use care to avoid bending any of the electrical
connection pins.
Be sure that each pin starts into its
receptacle
properly.
Tighten the four mounting screws
snugly to assure proper positioning
of the control
station.
Specific instructions
for the installation,
adjustment,
and operation of the various options are on instruction sheets packed with the options.
CONTROLLER
INSTALLATION
The Controller
must be wall mounted in a location
which will allow free flow of cooling air over the fins
on the beat sink. Maximum ambient temperature
around the controller
must not exceed 40°C (104°F).
Figure 3 gives mounting dimensions
and outline dimensions.
It is reeommendedthattwo
or more inches
of clearance
be provided all around the controller
to
assure adequate air flow through the beat sink fins of
units rated 3/4 tip or more.
Air flow over the units
rated less than 3/4 HP is also necessary
but less air
flow is required to cool the lower horsepower
units.
Conduit entering

Statotrol
II Motor
Control
the controller
enclosure
must be
and the controller
cover must be
to maintain
the NEMA 4/12 rating
INSTALLATION
The motor must be firmly mounted and properly
aligned to prevent vibration.
Excessive
vibration
causes rapid wear and objectionable
audio noise.
Heat dissipated
by the motor will raise the ambient
temperature
around the motor if the motor is installed in an enclosed
space.
Since a lower ambient
temperaturewill
extend the motor life, it is always
desirable
to mount the motor in a well ventilated location.
The motor should never be used where the
ambient temperature
exceeds 40 ° C (104 °F) unless
an oversized
motor has been specially
selected.

REMOTE CONTROL STATION WIRING
REMOTE ACCESSORY WIRING
When a remote control station is to be installed,
it
must be connected to a 3SRC2000 or 3SRC2001 series
adapter unit which plugs into the StatotrolH
controller
main component board.
The connections for the forward, reverse,
off, start, jog, run, and stop buttons
are Class II control circuits as defined in Article 725
of the National Electric Code (1971).
A seven point terminal
strip,
2TB, is provided
for
connection
of leads from remote accessories.
This
terminal
strip is not to be used unless one of the optional remote accessory
adapter units has been installed in the Statotrol controller.
(See Figure 2.)
Remote accessory
functions include tachometer
feedback, tachometer follower, instrument follower, and
speed indication.
Any combination
of these functions
can be used simultaneously
with the exception of the
tachometer
follower and the instrument
follower which
are mutually exclusive.
Conductors connected to the speed adjustment potentiometer,
the torque adjustment potentiometer,
and the auto-manual switch are Class II circuits if
the control is connected to 115 volt power.
If the
input voltage is 230 volts, conductors for these circults should be installed in accordance
with the Class
I control and signal circuit requirements
of Article
725 of the National Electric Code. Wherever local
codes are more restrictive,
the local codes take
precedence over the National Electric Code.
Figure
5 shows the various
remote control station
connection
schemes which can be used.
The control
wires should go through the conduit openings at the
top of the Statotrol II enclosure,
To avoid electrical noise pickup, it is necessary
to
keep the torque potentiometer,
speed potentiometer,
and auto-manual
switch wires separate
from all other
wires.
Do not run these wires through conduits with
power conductors or relay coil wiring,
If these leads are run in shielded cable, the cable
shield should be connected to circuit 2 at the controller
only. The cable shield must be insulated and must
not come into contact with plant ground at any point,
MOTOR THERMOSTAT
CONNECTIONS
When a motor thermostat
is used, it should be connected in series with the "off' switch.
Refer to
Figure 5 for connection
diagrams
of remote control
stations
with motor thermostats.
Local control stations (those which are inside the controller
enclosure)
have a jumper across two terminals
on the foil side
of the control station component
board.
Remove the
jumper and connect the thermostat
leads across these
two terminals.
Use insulated lugs on the thermostat
leads,
Figure 6 shows the wiring connections for remote
accessories.
The wiring shown should be considered
as Class I signal wiring (National Electric
Code, 1971,
Article 725), except that the speed indicator wiring
may be considered
Class II if the AC input power to
the control is l15V, and the instrument signal wiring
may be considered
Class II if the instrument
output
is limited as specified
in the referenced
code article.
The tachometer
feedback function is installed
by
coupling a 20 volt per 1000 RPM PY59JY DC tachometer to the motor and connecting the tachometer
leads to terminal strip 2TB as shown in figure 6.
The polarity of the signal and the direction
of rotation do not affect this connection.
The recommended
PY59JY tachometer
has only two terminals.
(The
identification numbers on the tachometer terminals
do not correspond
to the controller
terminal numbers.)
One of the optional remote accessory
adapter units,
3SFB1000 or 3SFBll00,
must be installed in the
Statotrol II controller (refer to Figure 2) to complete
the circuit,
The adapter units are factory connected
for use with motors rated 1725 RPM to 1800 RPM.
When used with a 2500RPMmotor,
jumper 7J on the
adapter unit must be opened by stopping it out with
wire cutters.
Refer to the instruction
sheet which
is packed with the remote accessory adapter unit
for complete instructions
on installation
and adjustment, including use of motors with higher speed and
tachometers
with higher output voltage.
The tachometer
follower signal is obtained from a 20
volt per 1000 RPM PY59JY DC tachometer
by connecting the tachometer
leads to points 97 and 2 on terminal
strip 2 TB as shownin Figure 6. The positive side of

WIRING CHECK
Any connection error in the power wiring can damage the control as soon as power is applied.
Any
short to building ground in the signal wiring can
cause damage as soon as power is applied, unless
the Statotrol II drive is connected to a line power
Isolation transformer.
If the controller
is connected to any instruments
or equipment which may
be grounded, a line isolation transformer
must be
used.
In no case should the circuit be grounded at
more than one point. If the drive is to be operated
as an instrument follower, verify that the correct
protechve shunt resistor
is properly installed.
(Refer to Figure 6. ) It is advisable to recheck all wiring before power is applied.
Make certain that all
screw terminals are tight. If an ohmmeter is available, the simple resistance
checks shown in Table
3 should be performed
to verify that the power wirlng is correct.

Always disconnect
anything other than adjusting
the controller
cover is
to avoid touching conAC power before doing
potentiometers,
INITIAL OPERATION AND ADJUSTMENT
When the control has been mounted and connected,
and the prepower
checks and adjustments
are eomplete, apply power to the control,
turn the speed control knob to zero, and press the "Start" button on the
control station.
Slowly turn the speed control knob
until the motor starts
to turn.
Check the direction
of motor rotation to be sure it is correct.
If [he
motor turns the wrong way, disconnect
power from
the control and reverse the motor armature
leads,
The control is now ready for normal operation.
Some
applications
may require special settings for maximum speed,
minimum speed, IR compensation,
and
torque taper.
Potentiometers
for adjusting these functions are in a line along one edge of the main eomportent board inside the controller.
Remove the
Statotrol
II cover and use a small screwdriver
to
adjust [he potentiometers
as described
in the following
instructions.
WARNING
i
AC power line voltage is exposed when
the protective cover is removed.
Use
extreme
care to avoid touching any exposed conductors
inside the controller,
Internal adjustments should be made by
qualified electricians,
and not by machine
operators,
MINIMUM SPEED ADJUSTMENT (4P)
The minimum speed adjustment is factory set so that
the motor will start to run when the speed control
knob is turned just slightly off zero.
To change this
setting, first turn the speed control knob to zero and
then rotate the minimum speed potentiometer
until
the motor runs at the desired minimum speed,
The minimum speed adjustment is also used to match
proper motor speed to specific signal levels when the
reference
signal comes from a signal generating
instrument.
This function is explained on the instruc-
with the remote
GEK_6370
accessory
adapter
Adjusting [he minimum speed changes the maximum
speed also, so the minimum speed should be set before
the maximum speed potentiometer
is adjusted.
MAXIMUM
SPEED
ADJUSTMENT
(3P)
i-_-_'_i_
......
- _
Do not change the factory setting of the maximum speed potentiometer
if tachometer
feedback is to be used.
If the maximum
speed potentiometer
is inadvertently
disturbed,
it should be returned
to approximately 80% of its possible
CW rotation.
The maximum
speed adjustment
does not
limit motor speed when the control is in
the "automatic"
mode of operation
(tachometer follower and instrument
follower
applications).
The maximum
speed adjustment
is factory set to a
speed slightly higher than rated motor speed.
To
change the maximum
speed, first turn the speed control knob to its highest speed setting.
Then adjust the
maximum speed potentiometer
until the motor runs at
the highest speed needed for the particular
application.
The Statotrol II drive may not meet its performance
specifications
when the motor is run above its rated
speed.
It is, therefore,
recommended
that the maximum speed be set for rated motor speed or less.
IR COMPENSATION
ADJUSTMENT
(6P)
Conventional IR compensation
boosts
the
motor speed at high load.
The Statotrol
II IR cornpensation
circuit provides
this feature
and can also
be adjusted to provide "droop" for applications
which
require motor speed to drop off linearly as load is
added.
The IR compensation adjustment is factory set
so that for a given speed setting,
the full load speed is
different
from the no load speed by about ±1% of rated
motor speed.
This setting is adequate for most applications.
When necessary,
the IR compensation
can
be adjusted by the followingprocedure.
Start the drive and set the speed control knob to the
speed at which regulation is most critical in your particular application.
Adjust the motor load to minimum
and then measure the motor speed precisely with a
hand tachometer
or a strobe light.
The speed of integral hp motors may be conveniently read by removing the dust cap on the commutator-end
motor bearing
and using a hand tachometer.
On fractional hp motors,
motor speed can be read with a strobe light at any convenient point where the rotating shaft can be seen.
Now adjust the motor load to maximum (not exceeding
100 percent rated torque) and again read motor speed.
STATOTROL II DC
ll _ DRIVE
T1
If the "maximum-load"
speed is less than the "Minimum-load"
speed, turn the IR compensation
potentiometer
clockwise
(CW) until they are equal.
There
is no need to wait for the motor to warm up since the
Statotrol II iR compensation
works equally well at any
motor temperature.
Some loads may "hunt" if the IR
compensation
is set too high.
Turning the IR compensation potentiometer
CCW should eliminate
this
hunting,
TORQUE TAPER ADJUSTMENT (5P)
_...........
_t_T'_-!_%
CAuTmON__
The torqqe taper adjustment
is factory
set full CCWo The torque taper adjustment must be kept full CCW when a control station with a manual torque control
knob is used.
In applications
requiring
a fixed program
of torque
control,
the torque taper adjustment
may be turned
clockwise to increase
the output torque which the
motor will deliver at low speeds.
OPTION ADJUSTMENT
The optional features
should not be adjusted
until
after any necessary
adjustments
of the maximum
speed, minimum speed, IR compensation,
and
torque taper have been completed.
Detailed inetructions
are on the instruction

TROUBLESHOOTING AND REPAIR
I WARNING
.Bearings
In general,
opening Statotrol
motors for bearing
maintenance
will create more problems
than it will
prevent.
However
if for some reason it is felt that
bearing maintenance
is necessary,
the bearings
should be relubricated
or replaced
after 5 years of
normal
service or 2 years of severe
duty.
Line voltage is exposed when the controller
cover is removed.
Use extreme care to avoid touching exposed
conductors°
Always disconnect
the AC
power before doing anything other than
adjusting
potentiometers.
The control
station stop button does not remove
power from the control or the motor
field.
Brushes
Brushes should be inspected after every 1000 hours
of operation.
Replacement
brushes
should be installed before old brushes
wear down to 3/8 of an
inch in length. Replacement brushes must be preshaped to approximately
conform to the curved cornmutator
surface.
The motor should be run near rated
speed for about 12 hours with no load to seat the new
brushes before the motor is returned to normal duty.
Failure
to seat the new brushes
may cause commutator damage and rapid wear.
Replacement
brushes
must be of the type recommended
by the motor manufacturero
Refer to the renewal parts section of this
book.
Mounting
The motor should be inspected periodically
to assure
that the mounting bolts are tight_ Loose mounting
bolts can cause vibration,
rapid wear, and misalignmento Proper
alignment
of motor couplings must be
maintained.
Ventilation
Do not allow an accumulation
of materials
to block
cooling air from flowing through open motors or
over totally enclosed
motors.
GEARBOX
Periodic
oil changes and bearing lubrication
are
necessary
to prolong the life of most gear boxes.
Refer to the instructions
provided with the unit for
recommended
maintenance
schedule and lubricants.
TACHOMETER
After 5 years of normal
service
or 2 years of severe
duty, the bearings
should be inspected.
If they appear to be loose or worn, they should be replaced,
Brush inspection and replacement
requirements
are
the same as for motors,
I
If a newly installed
drive will not run, it is most
likely that a terminal is loose
or a problem exists
with a connection
line voltage,
or an adjustment.
Line voltage must be within +10% of the nameplate
rating of the controller,
and the adjustments
must be
set as described in the "Initial Operation and Adjustmerits" section of this book.
If the drive operates
normally
for a while and then malfunctions,
the
problem
may be line voltage,
motor overload,
motor
failure,
a loose terminal;
an open fuse, or a cornponentfailure. In the followingdiscussions, each
step of troubleshooting
is based on the assumption
that all preceding
steps have been completed
and
nothing abnormal
has been found.

WARNING
!
Alwaysdisconnect the ACline voltage
from the control before replacing fuse.
Replace the fuse with one of the same type and amperage rating as the original fuse.
Next, connect an
AC voltmeter
across terminals
L1 and L2 on 1TB
and verify that the voltage is within ±10% of the nameplate rating of the control.
Next connect a DC voltmeter between terminals
F1 and F2 on 1TB and verify that the voltage is within ±10% of the field voltage
stated on the nameplate°
If the field voltage is 1/2 of
the rated value, one of the diodes in the field power
supply has probably failed.
These diodes are mounted
between 1TB and the fuse on the controller main

......
component
board°
If the field voltage is zero,
2 or
more diodes may have failed, or the fuse may be
open. If the field voltage is correct,
press the start
button, verify that the M relay (on the main component board) picks up, turn the speed control knob to
full speed, and read the DC voltage across
terminals
A1 and A2 on 1TB. If this voltage is about 10 or 20
volts the motor is stalled due to an overload or there
is an open in the motor leads, windings,
or brushes,
If this voltage is zero, turn the minimum
speed adjustment slowly from one extreme to the other.
If
the rooter now starts the problem is in the control
station and its plug-in contacts should be checked and
then the control station should be replaced°
If the
motor does not start,
the main component
board
along with the power semiconductor
package should
be replaced.
Motor
Runs At High Speed
And Cannot
Be Controlled
If the drive system is used as a tachometer
follower
or an instrument
follower,
try to operate
the control
in the manual mode.
If it works OK in manual
the
problem is probably in the tachometer
or instrument,
or the "Remote Accessory Adapter" option (see
Figure 2).
If the drive has tachometer feedback
remove the
remote accessory
adapter board (see Figure 2),
jumper between the two option connection receptacles 22 and 20 as indicated by the yellow line on
the main component board, and retest.
If the control has the "timed acceleration
and deceleration" option (see Figure 2), disconnect
the option.
Jumper between the two receptacles
7 and 10 as shown
on the main component board.
(An explanatory
note
on the main component board is exposed when the
option is removed.)
Reconnect the power and retest,
Disconnect
the AC power.
If the drive has a remote
control station,
disconnect
the wire from terminal
7
on the "Remote control station adapter"
(see Figure
2)
and tape the lug to prevent accidental short circuits,
If the ddrive has a local control station, look in the
control station and locate the wire (from the speed
control potentiometer)
which is plugged into either
point 7 or 7A (make a note of which it is) and pull
this wire loose.
Tape the loose end to prevent accidental short circuits.
Reconnect AC power and retest.
If the motor speed now responds
to the "minimum speed" adjustment,
there is a short circuit in
the control
station.
If the motor still runs at top
speed only, replace the main component
board,
including the power semiconductor package,
Motor Runs Very Fast For Speed Setting,
Little Torque is Produced
But Very
Check the AC line voltage from L1 to L2 on 1TB.
Verify that this voltage is within _10% of the value
stated on the nameplate.
Check the DC voltage from
F1 to F2 on 1TB. If this voltage is less than 3/4 of
the value stated on the nameplate,
one or more of the
12
GEK-36370
field power supply diodes on the main component
board has failed.
These diodes are between 1TB
and the fuse on the main component board.
Motor Operates Normally At N0 Load , But Will Not
Deliver Adequate Torque To Drive A Load
If the motor has operated properly in the past and
suddenly develops this symptom, the main component
board and/or the power semiconductor
package should
be replaced.
If this problem is evident immediately
upon instailation, refer to the section of this book titled "Prepower
Checks and Adjustments",
and check the current
limit
setting of the control.
If it is wrong, disconnect the
AC power and correct
it. If it was set per the table,
then disconnect the AC power, connect a DC ammeter
in series with the motor axmaiure,
and run the motor
with the load connected.
If the observed
DC current
is more than the nameplate rating on the motor, either
the motor has failed or the motor is overloaded.
If
the observed DC current is less than the nameplate
rating of the motor, check the setting of the torque
control knob, if the drive has one, and then disconneet the ACpower and reset the current limit adjustment to the setting appropriate
to the next higher irapedance group of motors in Table 2 and retest.
Motor Hunts
Too much IR compensation may cause some motorload combinations
to hunt° Turn the IR compensation
adjustment
CCW until the hunting stops.
If adjustment
of the IR compensation
does not correct
the problem,
verify that the motor is not being run at
higher than rated speed.
Then refer to the section of
this book titled "Prepower
Checks and Adjustments",
and check the current limit setting of the control.
If
it was not set per Table 2, disconnect
the AC power
and correct it. If it was set per the table, then disconnect the AC power and change the current
limit
adjustment to the setting appropriate
to the next lower
impedance group of motors in Table 2, and retest_
Fuse Blowing
If the control is being used with 50 Hz power, verify
that resistor
i40R has been cut out of the circuit as
shown on Figure 7.
If the fuse blows within a few seconds after power is
applied,
there is probably a short circuit or a wiring
problem.
If the fuse blows after a few minutes or a
few hours of steady running, the motor is probably
overloaded.
To check for an overload condition,
measure
the DC current
in the motor armature.
This
current
should not exceed the rated armature
current
which is stamped on the motor nameplate.
The fuses have been selected to provide the maximum
possible
protection for the drive.
However,
if the
application requires the motor to start and stop or

The controller
switch does not remove
voltage from the motor field.
Always
disconnect
the AC power from the controller before attempting to service
motor,
The motor can be repaired
lust as a standard DC
motor by any competent motor repairman.
For replacement
parts or motor service,
take the motor
model number from the motor nameplate
and contact
the nearest serwce shop authorized by the motor
manufacturer.
Controller Repairs
Normal field repair should be limited to replacing
component boards,
fuses, options,
and the SCR power
14
module.
The complexity
of the test sequence
reqmred
to verify proper operation of a component board after
repair makes it highly advisable to return failed component boards to General Electric Company for repair
and retest by the trained personnel and automatic test
equipment at the factory.
When emergency
repairs
are required
in the field,
the following cautions should be observed.
Always
disconnect
AC power from the control before performing any work on any part of the circuit.
The controller switches do not remove voltage from the
circuitry.
When soldering components to a printed
c_rcuit
use the
amount
of solder.board,
Do always
not overheat
thesmallest
leads of possible
semi-conductor components such as SCR's, diodes, transistors,
and integrated circuits.
After soldering, inspect
carefully to be certain that solder has not bridged between foil paths or reduced the electrical
clearance
between
foil paths.
Solder
flux from
is conductive
so flux
accumulations
must be
cleaned
the component
board when soldering is complete.
Solder icicles and
component
leads must be trimmed
from the bottom of
the board to prevent short circuits to the heat sink.
Many components
on the board are very fragile
and
must be protected
from damage while the component
board is being handled.
To remove the component
board, first remove
the four
control station mounting
screws and remove
the control station.
Now remove the dynamic braking reslstor (DBR) and the reversing
option, if they are present. Next, remove two screws from the Transformer
(1T) mounting feet, two screws from the SCR
power module,
and two component board mounting
