DESCRIPTION
The Model 850 Two Hand Control Module is designed to be
used with two palm or pushbutton switches, which must be
closed within 0.5 seconds of each other to operate machinery.
As long as both switches are pressed, the relay will remain
energized in the continuous mode.
For applications requiring a pulse to initiate operations, the
Model 850 can be set to produce a pulse output by connecting
a resistor to pins 4 and 7. The resistor value in ohms should be
100,000 times the desired time in seconds (R=100,000 x T).
The internal relay de-energizes on completion of the pulse,
even if both switches are depressed. The relay de-energizes
immediately,if either hand switch is released, in standard or
pulsed mode.
The compact size of the Two-Hand Control Module allows
installation into an existing control panel. It can be used with
any type of machinery requiring safe, two-handed operation
such as presses, punches, cutters, etc. The standard nominal
supply voltages are 120VAC, 240VAC, 24VAC, 24VDC.
Other voltage versions may be available by special request.

DESCRIPTION
The Model 295 Capacitor Trip Device is used to trip
circuit breakers by using the stored energy in a capacitor.
The capacitor is kept at full charge during normal operation
by a half-wave silicon rectifier which draws its energy from
the power line.
When completely discharged, the Model 295 draws
approximately 10 amps from the line in the first half cycle,
3 amps the second half cycle and 1 amp from the third.
Continuous current required to keep the capacitor charged
is less than 5 milliamps.
The capacitor holds sufficient charge to trip the breaker for
at least 12 seconds after the charging voltage is removed.
However, on most fault conditions, some voltage is still
present, so the Model 295 is designed so that 65% of
normal voltage gives sufficient charge to trip the breaker.
A low-energy lamp, connected in parallel with the storage
capacitor, gives a visual indication when the voltage
charge is 85 volts or more on the 120V version and 170
volts or more on the 240V version.

DESCRIPTION
The Model 410 Auto-Charged Capacitor Trip Device is
a high speed capacitor-type circuit breaker tripping unit. It
differs from the conventional capacitor trip device in that it
has a self-contained standby power source, which is
capable of maintaining full operating voltage for several
days.
This device is primarily for use with circuit breakers which
require some form of AC power for their closing operation;
i.e., circuit breakers having either a stored energy closing
mechanism with an AC-operated release coil, or an AC
solenoid-operated closing mechanism. There are no field
adjustments required.
The Model 410 has a cover-actuated safety switch, which
discharges the capacitor and disconnects the primary
source when the cover is removed.
The Model 410 can be tripped manually, or by means of a
voltage-sensing or phase loss monitor. Versions are
available for 120 vac or 240 vac operations.

MODEL 410
Auto-Charged
Capacitor Trip Device

PRE-INSTALLATION CHECK
The energy storage capacitor used in the Model 410 is a
special high grade, low leakage, industrial type electrolytic
capacitor. One trait of any electrolytic capacitor is the
tendency to change characteristics when left de-energized
for extended periods.
Although these units have been completely tested at the
factory, they may be stored for a considerable length of
time. To insure proper performance, it is highly recom-
mended that this unit be energized from the power source
for a minimum two hours just before putting it into
operation. This will insure that the unit will operate at
maximum efficiency.
CHECK THE BATTERY. If the battery has run down, it is
best to replace it, or to re-charge it EXTERNALLY, before
installation.
INSTALLATION
Before putting the Model 410 into service, it should be
examined carefully to make certain that the unit has not
been damaged during shipment.
Verify that the supply voltage is of the proper value and
frequency (see Specifications table).
Mount the Model 410 in the desired location.
Connect the operating power source and output tripping
circuit (refer to Typical Application example).
CAUTION
The Model 410 uses a half-wave rectifier circuit to
charge the energy storage capacitor from the source.
With this type of circuit, it is important that no load be
placed across the energized capacitor (pins 1 & 3).
Should this occur, no charge can be built up across
the capacitor; the rectifier and current limiting resistor
will then be subjected to prolonged, excessive current
resulting in their DESTRUCTION.
Under normal operating conditions, the capacitor is protected
from damage since it’s source is applied from either the
battery and it’s associated circuitry, or from the circuit breaker,
thus keeping all loads from the capacitor. There is ample time
during a circuit breaker closing operation for the capacitor to
charge since it requires only 3 cycles for the unit to reach 90%
(applies to 240vac only) of full charge.
During testing of the unit, with it’s associated circuit
breaker, care should be exercised not to have the tripping
circuit completed while applying AC voltage to a
discharged unit.
OPERATION AND MAINTENANCE
The operation of the Model 410 is completely automatic, requiring
only an occasional check to determine if the unit is functioning
properly. A front panel neon light and rocker switch are supplied
for this purpose. If the voltage across the capacitor is above the
minimum required to operate the breaker, the light will glow when
the test button is pressed. This indicates the readiness of the unit
to trip the breaker,but it does not indicate the status of the
external power source, or the internal battery circuit.
FIELD SERVICE AND ADJUSTMENT
The Model 410 has been completely checked and adjusted at
the factory. It is advisable not to disturb these adjustments. If
for any reason the unit fails to operate properly, it should be
returned to the factory for repair, or re-calibration.
REPAIRS
The Model 410 Auto-Charged Capacitor Trip Device is not
field repairable. Should this unit require repairs, call Time
Mark Corporation at 800-862-2875 (8 a.m. to 5 p.m. CST) for
instructions on returning it to the factory for service.
WARRANTY
The Model 410 Auto-Charged Capacitor Trip Device is war-
ranted to be free from defects in materials and workmanship
for one year. Should this device fail to operate, we will repair
or replace it for one year from the date of purchase. For com-
plete warranty details, see the Terms and Conditions of Sales
page in the front section of the Time Mark catalog.

DESCRIPTION
The Model 412 Automatic Reverse Controller is a
current sensor designed to detect jamming of sewage
grinders, and to initiate the reversing of the grinder.
This controller allows the selection of up to 5 forward/
reverse cycles, and provides for an alarm output if the
number of cycles is exceeded.
The current loop inputs are designed for direct
connection of 10 amps at 240VAC, or 5 amps at
480VAC (up to 2 hp motors). For higher currents, a
current transformer (CT) must be used (CT
secondaries are connected to the 5 amp terminals,
regardless of voltage).
A push-button is used to simulate an over-current
condition and to test the relay contacts and alarm. A
current level adjustment is used to optimize the trip
point setting. LED indicators show the running direction
of the motor and the alarm condition.
OPERATION
When operating the Model 412 in the forward mode, an
over-current condition of a half second will cause the
START contact to open for 3 seconds. The FWD/REV
contact switches to REV and the START contact re-
closes. One half second later the START contact opens
and the FWD/REV contact switches to FWD. Three
seconds later the START contact will close.
If the over-current condition persists, this sequence
repeats for the number of cycles selected. After the last
cycle, the START contact opens and the ALARM
contact closes. The controller is locked out and must be
reset by removing and re-applying the operating
voltage.

Figure 1. RESISTIVE LOAD
With a purely resistive load, the current and voltage
waveforms are occurring simultaneously.
MODEL 421 Over/Under Motor Load Monitor
READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.
KEEP THIS DATA SHEET FOR FUTURE REFERENCE.
APPLICATION GUIDE
Figure 2. INDUCTIVE LOAD
With an inductive load, the current waveform lags the
voltage waveform by 60°.
The current, as measured with an ammeter, may only
vary a slight amount as the motor changes from a fully
loaded condition to a completely unloaded condition.
This makes it difficult to detect an unloaded condition by
simply monitoring current alone.
To obtain an accurate picture of real power
consumption of any inductive device, such as a motor,
the formula V x A x Cosø = W is used.
The Cosø is a multiplication factor derived from the
number of degrees of lag between the current and
voltage waveforms.
This is called the “power factor” (or “PF”). The power
factor is the natural cosine of the degrees of lag:
GENERAL
This application guide is written for equipment
designers, maintenance personnel, electrical
contractors, etc.
It is intended to aid in the installation of the Model 421
Motor Load Monitor into motor protection systems.
The notes and diagrams deal with methods of protecting
motors in the event of an underload condition or an
overload condition.
THEORY
The need for a system to detect an underload condition
other than by the simple monitoring of current becomes
clear when examining the following waveforms.
In a purely resistive circuit, as in Figure 1, the current
(amps) is directly proportional to the power (watts) being
consumed. To find the power, multiply the voltage
across the load times the current through the load. The
result is in watts (V x A = W).
In Figure 2, When the load is not resistive, but inductive
as it is with a motor, the formula is no longer correct.
The inaccuracy occurs because the current and the
voltage waveforms are not in phase.
The current waveform lags the voltage waveform by as
much as 90 degrees in a completely unloaded
condition, or as little as 5 or 10 degrees in a fully loaded
condition.

Example: TRUE POWER CONSUMED BY AN AC
MOTOR
For this example we will use a 3-horsepower, 230 volt,
single phase motor.
Condition 1 represents the motor being used at near full
load, while Condition 2 represents a drop in motor load.
Comparing the results of this example, the motor
current decreased only 10% with a drop of 61% in the
motor load (input power). A drop in motor power
cannot be accurately measured by only monitoring the
current and voltage.
By monitoring the phase relationship and applying the
resultant power factor,an accurate and selective
method of sensing changes in true power consumption
can be obtained.
The Model 421 Monitor is based on the above principal
of detecting the actual power used, and is more
sensitive than simple current monitors.
ADDITIONAL FEATURES
As described previously, the Model 421 would fulfill the
basic requirements in most motor protection control
systems. However, there are situations which would
require the motor to restart automatically after a preset
time.
The Model 421 has an adjustable restart timer for
such applications. This timer has a range of 0.1 to 4
hours. If the restart timer is not needed, turn it off with
DIP switch 2.
If restart timing is needed for an underload condition
only, the overload restart can be turned off with DIP
switch 1.
Resetting the Model 421 is accomplished by cycling the
power off and back on, pressing the RESET button, or
by using the restart timer (DIP switch 2).
Some applications require a trip delay period before
shutting down the motor. The Model 421 has a built-in
trip delay timer. The timing range is from 0.3 to 180
seconds. The trip delay timer can be turned off with
DIP switch 4.
Refer to the chart under INSTALLATION (pg 4) for all DIP
switch settings.
Example: (V x A x Cosø = Watts)
Condition 1
230 volts x 10 amps x 0.985 pf = 2265.5 watts
Condition 2
230 volts x 9 amps x 0.423 pf = 875.6 watts
A 4-20 mA output is provided for monitoring power
consumption. A 4 mA output is equal to 0 watts and a
20 mA output is equal to 600 watts at 120 V or 1200
watts at 240 V.
This signal can be sent to a strip chart recorder, a
process controller, computer, etc.
INPUT CURRENT REQUIREMENTS
The CT input of the Model 421 is the isolated winding of
a small current transformer within the unit. Ideally, the
current range needed should be between 2 and 3.5
amps for a fully loaded motor.
Polarity of the wires connected to the CT terminals is
critical to achieve the correct phase relationship
between the current and voltage waveforms as
described earlier.
This is simple to determine after the installation is
complete (refer to the ADJUSTMENT PROCEDURE, pg
5).
If the full load motor current is 3.5 amps or less, and
the motor is a single-phase type, connect one leg of the
motor current directly into the Model 421.

3-PHASE INSTALLATION
The basic Model 421 Controller is designed for use with
single-phase motors. However, it can easily be used in
3-phase applications by installing the current cancelling
transformer, Model 276C. The Model 276C (figure 6)
monitors two of the three phases, and cancels the effect
of the current signal in the third phase, which would
otherwise cause a phase shift error in the Model 421.
Figure 6. MODEL 276C
IMPORTANT NOTE:
In 3-phase applications, the current inputs must
come from the same phases providing the voltage
inputs. The applications schematics shown on the
last page describe the interconnections.
INSTALLATION
Mount the Model 421 in the control panel or in a suitable
enclosure. Connect the voltage and current inputs to
the appropriate terminals on the Model 421 Monitor.
If the 4-20mA output is used, connect it across a 300Ω
resistive load. Set the four MODE switches on the
Model 421 according to the chart below. During the
initial setup you may wish to disable all time delays.
After the system is completely installed, a simple test
and adjustment will insure that the polarity and
threshold are correct.

ADJUSTMENT
Connect a temporary jumper across the NO contacts on
the Model 421 (this keeps the motor running as the
Model 421 trips off and resets).
With the correct voltage applied to the system, the
motor should start and run continuously. Make sure the
motor is running under it’s normally loaded condition.
With a clamp-type ammeter, measure the current in one
of the wires connected to the CT terminals on the Model
421. A reading between 2 and 3.5 amps should be
measured for best results. This current level can be
changed by exchanging the CT with a different ratio.
Turn the UNDER adjustment through it’s entire range
and find the spot where the UNDERLOAD LED just
illuminates.
Turn the UNDER adjustment until the LED just goes
out. If the UNDERLOAD LED is lit all the time, reverse
the two wires connected to the CT terminals and re-
adjust.
Repeat this procedure for the OVER adjustment. If the
OVERLOAD indicator LED stays on all the time, the
current input may be incorrect. Check the CTs for
proper sizing.
Set the SECONDS adjustment for the appropriate TRIP
delay, and HOURS adjustment for the appropriate
RESTART delay, as required for the application.
Remove the jumper from the NO contacts; the motor
should continue to run. The adjustment is now
complete.

DESCRIPTION
The Model 640 Power Factor Regulator is a monitoring and
control factor correction system. It was designed to help
obtain an improved power factor, with a minimum of added
capacitors. This device uses a unique phase-angle sensing
circuit to monitor the power factor of a 3-phase power line.
The Model 640 automatically responds to changing power
factor by closing or opening the internal relays, which add or
subtract capacitor banks on the line. Although intended for
115VAC 60Hz systems, other voltage or frequency models
may be available.
OPERATION
The Model 640 has a LOW POWER FACTOR control,
adjustable between 0.50 and 0.95. If the power factor drops
below this setting, the unit will begin adding capacitor stages
each 40 seconds, until the high PF setting is reached. The
HIGH POWER FACTOR control is adjustable between 0.80
and 1.00 and should always be set higher than the low setting.
The Model 640 will drop out one stage of capacitors every 40
seconds if the power factor becomes capacitive (or leading too
much capacitance). This continues until the power factor is
again inductive (lagging).
A manual mode allows capacitance to be removed or added at
the push of a button. If the operating voltage is lost or the
input current is too low, all relays will drop out.
Indicator lights on the face of the Model 640 show if the power
factor is inductive or capacitive. Output lights show relay
status. An output is provided to drive a 1 mA DC meter.
Center scale on the meter will indicate a power factor of 1.0; a
left deflection will indicate a capacitive power factor, while a
right deflection will indicate aninductive power factor. Use of
an external meter is optional.

POWER FACTOR DEFINED
The Power Factor, or PF, is stated as a decimal number
between 0 and 1, and is the cosine of the angle between the
voltage and current wave forms. In AC circuits, power (in
watts) is defined as voltage xcurrent xpower factor. From
this, you can see that with a power factor of 0 there can be no
power, regardless of how large the voltage or current may be.
A normal inductive motor will have a power factor between
0.30 and 0.90, depending on how the motor is loaded.
OPERATING THRESHOLDS
A current threshold adjustment is used to set the point where
the Model 640 will disconnect all of the capacitors. This
current threshold is adjustable between 0.25 and 1.00 amp,
from the current transformer. This threshold sets the point
below which the unit is inoperative. A power loss to the Model
640 will also cause all capacitors to be disconnected.
MANUAL OPERATION
The Model 640 can be operated manually. Capacitor stages
can be added or subtracted with a push button on the front of
the unit.
OPTIONAL DISPLAY METER
A meter signal is provided from the Model 640 for a DC meter
with a 0-1 milliamp movement. The meter calibration will be:
0.1 ma = 0.50 power factor (capacitive)
0.5 ma = 1.00 power factor
0.9 ma = 0.50 power factor (inductive)
The meter output is nonlinear, i.e. 1.00 PF = 0.5 ma DC;
0.5 PF = 0.90 ma DC. Refer to Chart 1. for details.
HOW TO SELECT CAPACITORS
Power factor correcting capacitors and capacitor banks are
normally rated in KVARS. There are three basic steps to
properly size the capacitors to a given application:
Determine present load, measured in KW
Determine present power factor
Determine desired power factor
Using Chart 2. on page 4, locate the original (present) power
factor in the vertical left-hand margin. Locate the desired
(corrected) power factor across the top of the chart.
The correction factor (a three place decimal number) is
denoted at the intersection of the row and column of these two
figures.
The correction factor is next multiplied by the present KW
load. The result is the required capacitor size, stated in KVAR.
Correcting to a power factor of 0.95 is generally considered
optimum; correcting to a leading, or capacitive, condition
should not be attempted.
When the total KVAR requirement is determined, it can be
divided among the six stages of the Model 640, to provide six-
step power factor correction. When installing capacitors,
consult the manufacturer’s literature for fusing and
contactor requirements.
In addition to the capacitors and contactors, a properly sized
current transformer with a minimum burden rating of 2 VA and
a 5 amp secondary is required. You will also need a power
transformer with a 115 VAC secondary at 50 VA minimum.
Proper phasing of CT and the PT is essential. If correction
stages work in reverse, disconnect power and reverse the CT
secondary leads.
TROUBLESHOOTING
Should this regulator fail to operate properly, check that all
voltages are present and of the correct level. Check to see if
all wiring is correct. If problems persist, contact the
manufacturerat 800-862-2875; Monday thru Friday, 8 a.m. to
5 p.m. CST.
