Safety Warnings
• This symbol denotes an important safety tip or warning.
Please read these instructions carefully before performing
any of the procedures contained in this manual.
•
DO NOT INSTALL, REMOVE, OR REWIRE THIS
EQUIPMENT WITH POWER APPLIED. Have a qualified
electrical technician install, adjust and service this equipment.
Follow the National Electrical Code and all other applicable
electrical and safety codes, including the provisions of the
Occupational Safety and Health Act (OSHA), when installing
equipment.
•
Reduce the chance of an electrical fire, shock, or explosion by
proper grounding, over-current protection, thermal protection,
and enclosure. Follow sound maintenance procedures.
It is possible for a drive to run at full speed as a result of
a component failure. Minarik strongly recommends the
installation of a master switch in the main power input to
stop the drive in an emergency.
Circuit potentials are at 115 VAC or 230 VAC above
earth ground. Avoid direct contact with the printed circuit
board or with circuit elements to prevent the risk of serious
injury or fatality. Use a non-metallic screwdriver for
adjusting the calibration trimpots. Use approved personal
protective equipment and insulated tools if working on this
drive with power applied.

Installation
Chassis drives
Mounting
Warning
Do not install, rewire, or remove this control with power
applied. Doing so may cause fire or serious injury. Make
sure you have read and understood the Safety Warnings
before attempting installation.
The chassis must be earth grounded. Use a star washer
beneath the head of at least one of the mounting screws to
penetrate the anodized chassis surface and to reach bare
metal.
• Drive components are sensitive to electrostatic fields. Avoid
contact with the circuit board directly. Hold the drive by the
chassis only.
• Mount the drive with its board in either a horizontal or vertical
plane. Six 0.19 inch (5 mm) wide slots in the chassis accept #8
pan head screws. Fasten either the large base or the narrow
flange of the chassis to the subplate.
8
Wiring
Warning
Do not install, remove, or rewire this equipment with
power applied. Failure to heed this warning may result in
fire, explosion, or serious injury.
Circuit potentials are at 115 or 230 VAC above ground. To
prevent the risk of injury or fatality, avoid direct contact with
the printed circuit board or with circuit elements.
Do not disconnect any of the motor leads from the drive
unless power is removed or the drive is disabled. Opening
any one motor lead may destroy the drive.
• Use 18-24 AWG wire for speed adjust potentiometer wiring.
Use 14–16 AWG wire for AC line (L1, L2) and motor (A1 and
A2) wiring.
9
Shielding guidelines
Warning
Under no circumstances should power and logic leads be
bundled together. Induced voltage can cause unpredictable
behavior in any electronic device, including motor controls.
As a general rule, Minarik recommends shielding of all
conductors.
If it is not practical to shield power conductors, Minarik
recommends shielding all logic-level leads. If shielding is not
practical, the user should twist all logic leads with themselves to
minimize induced noise.
It may be necessary to earth ground the shielded cable. If noise is
produced by devices other than the drive, ground the shield at the
drive end. If noise is generated by a device on the drive, ground
the shield at the end away from the drive. Do not ground both
ends of the shield.
If the drive continues to pick up noise after grounding the shield,
it may be necessary to add AC line filtering devices, or to mount
the drive in a less noisy environment.
10
Speed adjust potentiometer
Warning
Be sure that the potentiometer tabs do not make contact with
the potentiometer enclosure. Grounding the input will cause
damage to the drive.
On chassis drives, install the circular insulating disk between
the panel and the 10K ohm speed adjust potentiometer. Mount the
speed adjust potentiometer through a 0.38 inch (10 mm) hole with
the hardware provided (Figure 5). Twist the speed adjust
potentiometer wire to avoid picking up unwanted electrical noise.
If potentiometer leads are longer than 18 inch (457 mm), use
shielded cable.
All cased controls come with the speed adjust potentiometer
installed.

Line fusing
Minarik drives require an external fuse for protection. Use fast
acting fuses rated for 250 VAC or higher, and approximately
150% of the maximum armature current. Fuse only the hot leg

AC line voltage is 115 VAC. Fuse both L1 and L2 when the AC
line voltage is 230 VAC. Fuse blocks are included on cased
drives only. Table 1 lists the recommended line fuse sizes.

Heat sinking
Model MM23002D requires an additional heat sink, Minarik part
number 223-0159, when the continuous armature current is above
5 ADC. All other chassis drives have sufficient heat sinking in
their basic configurations. Use a thermally conductive heat sink
compound (such as Dow Corning® 340 Heat Sink Compound)
between the drive chassis and heat sink surface for optimum heat
transfer.
Connections
Warning
Do not connect this equipment with power applied.
Failure to heed this directive may result in fire or serious
injury.
For chassis drives, Minarik strongly recommends the
installation of a master power switch in the voltage input line
as shown in Figure 6 (page 15). The switch contacts should
be rated at a minimum of 200% of motor nameplate current
and 250 volts.
13
Power, fuse and motor connections
Connect the power input leads, an external line fuse and a DC
motor to the drive’s printed circuit board (PCB) as shown in
Figure 6, page 15.
Motor
Connect a motor to PCB terminals A1 and A2. Ensure that the
motor voltage rating is consistent with the drive’s output
voltage.
Power input
Connect the AC line power leads to terminals L1 and L2, or to a
double-pole, single-throw master power switch as shown in
Figure 6, page 15 (recommended).
Line fuse
Wire an external line fuse between the stop switch (if installed)
and the L1 terminal on the PCB. An additional line fuse should
be installed on L2 if the input voltage is 230VAC. The line
fuse(s) should be rated at 250 volts and 150 - 200% of maximum
motor nameplate current. Refer to the Table 1 on page 11 for fuse
ratings.
14
Master power switch
If you use a chassis (uncased) drive, Minarik strongly
recommends the installation of a master power switch in the
voltage input line, as shown in Figure 6. The switch
contacts should be rated at a minimum of 200% of motor
nameplate current and 250 volts.

Instead of using an external speed or torque adjust potentiometer,
the drive may be wired to follow an analog input voltage signal
that is isolated (Figure 7). The analog input voltage range is 0 2.5 VDC.
Connect the signal input (+) to S2. Connect the signal
common (-) to S1. Make no connection to S3. A potentiometer
can be used to scale the analog input voltage. An interface device
such as Minarik model PCM4, may be used to scale and isolate an
analog input voltage.

Cased drives
Mounting (NEMA 1 enclosures)
NEMA 1 cased drives come with 0.88 inch (22 mm) conduit
holes at the bottom of the case. The units may be vertically wall
mounted or horizontally bench mounted using the three keyholes
on the back of the case (see Figure 2, page 4).
1. For access to the keyholes and the terminal strip, remove the
two screws from the front of the case by turning them
counterclockwise. Grasp the front cover and lift it straight out.
2. Install the mounting screws in the three keyholes.
3. Install conduit hardware through the conduit holes at the
bottom of the case. Connect external wiring to the terminal
block. Refer to Figure 8 on page 21.
4. Reinstall the front cover. Avoid pinching any wires between the
front cover and the case.
5. Replace the two screws to the front cover. Turn the screws
clockwise to tighten.
6. Set the POWER switch to the OFF position before applying the
AC line voltage.
18
Mounting (NEMA 12 / 4 / 4X enclosures)
NEMA 12 / 4 / 4X cased drives come with two 0.88 inch (22
mm) conduit knockout holes at the bottom of the case. The units
may be vertically wall mounted using the four 0.19 inch (5 mm)
slotted holes on the attached heat sink (see Figure 3, page 5). For
motor loads less than 5 ADC, the drive may be bench mounted
horizontally, or operated without mounting.
1. Install the mounting screws.
2. For access to the terminal strip, turn the slotted screw on the
front cover counterclockwise until it is free from the case. The
right side of the cover is hinged to the case. Pull the slotted
screw to open the case.
3. Carefully remove the conduit knockouts by tapping them into
the case and twisting them off with pliers.
4. Install conduit hardware through the 0.88 inch (22 mm)
conduit holes. Connect external wiring to the terminal block.
5. Grasp the slotted screw and tilt the front cover back into place.
Avoid pinching any wires between the front cover and the case.
6. Turn the slotted screw clockwise until tight to secure the front
cover.
7. Set the POWER switch to the OFF position before applying the
AC line voltage.
19
Heat sinking
Models MM23102 and MM23202 require additional heat
sinking when the continuous armature current is above 5 ADC.
Use Minarik part number 223-0174. All other cased drives
have sufficient heat sinking in their basic configurations. Use a
thermally conductive heat sink compound (such as Dow
Corning® 340 Heat Sink Compound) between the back of the
drive case and heat sink surface for optimum heat transfer.
Line fusing
15-amp line fuses are preinstalled on models MM23102,
MM23202 and MM23402 and 3-amp line fuses are preinstalled
on models MM23112, MM23212, and MM23412.
If the horsepower rating of the motor being used is less than the
maximum horsepower rating of the drive, the line fuse may have
to be replaced with a lower rated one. Refer to the
“Recommended Line Fuse Sizes”, Table 1 on page 11 to install a
lower rated fuse.
20
All drives
• Protect the drive from dirt, moisture, and accidental contact.
Provide sufficient room for access to the terminal block and
calibration trimpots.
• Mount the drive away from other heat sources. Operate the
drive within the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of
the drive.

are set to their correct position. If the switches are
improperly set to a lower voltage position, the motor will not
run at full voltage and may cause damage to the transformer.
If the switches are improperly set to a higher voltage
position, the motor will overspeed, which may cause motor
damage.

voltage, derate the nameplate motor speed and torque by at
least 30%. Contact the factory for details.
25
Warning
TORQUE and MAX SPD trimpots must be recalibrated
everytime the drive is switched between SPEED and
TORQUE mode.
Speed Mode
In Speed Mode, the external potentiometer adjusts the speed
(voltage) of the motor. The on-board Torque trimpot sets the
maximum torque available. The drive comes factory calibrated for
speed mode.
To run the drive in Speed Mode, jumper pins 2 & 3 and pins 4 &
5 on J503. See Figure 10 and Figure 11 on page 26.
Torque Mode
In Torque Mode, the external potentiometer adjusts the torque
(current) of the motor. The on-board MAX SPD trimpot sets the
maximum torque limit. The on-board TORQUE trimpot sets the
maximum speed to the motor.
To run the drive in Torque Mode, jumper pins 1 & 2 and pins 3 &
4 on J503. See Figure 10 and 11 on page 26.

BRAKE position. To coast the motor to a stop, set the POWER
switch to the OFF position.
29
Starting and Stopping Methods
Warning
Minarik strongly recommends the installation of an
emergency stop switch. The switch contacts should be rated
at a minimum of 125 volts and 200% of maximum motor
current.
For frequent starts and stops, short the inhibit terminals,
decelerate to a minimum speed, or apply a dynamic brake to
the motor. Do not use any of these methods for emergency
stopping. They may not stop a drive that is malfunctioning.
Removing AC line power (both L1 and L2) is the only
acceptable method for emergency stopping.
Frequent starting and stopping can produce high torque. This
may cause damage to motors, especially gearmotors that are
not properly sized for the application.
Line starting and line stopping
Line starting and line stopping (applying and removing AC line
voltage) is recommended for infrequent starting and stopping of a
drive only. When AC line voltage is applied to the drive, the
motor accelerates to the speed set by the speed adjust
potentiometer. When AC line voltage is removed, the motor
coasts to a stop.
30
Inhibit terminals
Open or short the INHIBIT terminals to coast the motor to
minimum or zero speed (see Figure 12 for INHIBIT terminal
location). Reopen the INHIBIT terminals to accelerate the motor
to set speed. The drive will exhibit different responses to shorting
these terminals, depending on the way they are shorted (see
Figure 13, page 31). The INHIBIT function is the same for Speed
or Torque Mode.
Minarik Corporation offers two accessory plug harnesses for
connecting to the INHIBIT terminals: part number 201-0024
[inhibit plug with 18 inch (46 cm) leads]; and part number
201-0079 [inhibit plug with 36 inch (91 cm) leads].
S
Twist inhibit wires and separate them from other power-carrying
wires or sources of electrical noise. Use shielded cable if the
inhibit wires are longer than 18 inches (46 cm). If shielded cable
is used, ground only one end of the shield to earth ground. Do not
ground both ends of the shield. See Shielding Guidelines, page 9.

Decelerating to minimum speed
The switch shown in Figure 14 may be used to decelerate a
motor to a minimum speed. Closing the switch between S1 and
S2 decelerates the motor from set speed to a minimum speed
determined by the MIN SPD trimpot setting. If the MIN SPD
trimpot is set full CCW, the motor decelerates to zero speed when
the switch between S1 and S2 is closed. The DECEL trimpot
setting determines the rate at which the drive decelerates. By
opening the switch, the motor accelerates to set speed at a rate
determined by the ACCEL trimpot setting.

Dynamic braking
Warning
Wait for the motor to completely stop before switching it
back to RUN. This will prevent high armature currents
from damaging the motor or drive.
Dynamic braking may be used to rapidly stop a motor
(Figure 15, page 34). The RUN/BRAKE switch must be sized
appropriately for braking current. For the dynamic brake resistor,
use a high power wirewound resistor.
Dynamic brake resistor value
Sizing the dynamic brake resistor depends on load inertia, motor
voltage, and braking time. Use a lower ohm-value, higher-wattage
dynamic brake resistor to stop a motor more rapidly.
For motors rated 1/17 horsepower and lower, a brake resistor is
not necessary since the armature resistance is high enough to stop
the motor without demagnetization. Replace the dynamic brake
with 12 gauge wire. See below equations to determine
approximate size of dynamic brake resistor.

Calibration
Warning
Dangerous voltages exist on the drive when it is powered.
When possible, disconnect the voltage input from the drive
before adjusting the trimpots. If the trimpots must be
adjusted with power applied, use insulated tools and the
appropriate personal protection equipment. BE ALERT.
High voltages can cause serious or fatal injury.
MM23002 series drives have six user adjustable trimpots:
MIN SPD, MAX SPD, ACCEL, DECEL, TORQUE, and IR
COMP. Each drive is factory calibrated to its maximum current
rating. Readjust the calibration trimpot settings to accommodate
lower current rated motors.
All trimpot settings increase with clockwise (CW) rotation, and
decrease with counterclockwise (CCW) rotation. Use a nonmetallic screwdriver for calibration. Each trimpot is identified
on the printed circuit board.

MIN SPD
The MIN SPD setting determines the motor speed when the speed
adjust potentiometer is turned full CCW. It is factory set to zero
speed.
Use the following procedure to set MIN SPD:
1. Set the speed adjust potentiometer full CCW.
2. Adjust the MIN SPD trimpot until the motor has stopped (for
zero speed setting), or is running at the desired minimum
speed.
MAX SPD
The MAX SPD setting determines the motor speed when the
speed adjust potentiometer is turned full CW. It is factory set for
maximum rated voltage.
Use the following procedure to set MAX SPD:
1. Set the speed adjust potentiometer full CW.
2. Adjust the MAX SPD trimpot until the motor is running at the
desired maximum speed.
38
TORQUE
Warning
TORQUE should be set to 150% of motor nameplate current
rating. Continuous operation beyond this rating may damage
the motor. If you intend to operate beyond the rating,
contact your Minarik representative for assistance.
The TORQUE setting determines the maximum torque for
accelerating and driving the motor. To calibrate TORQUE refer
to the recommended TORQUE settings in Figure 17 on page 43,
or use the following procedure:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the TORQUE trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer to maximum speed
(full CW).
4. Carefully lock the motor armature. Be sure that the motor is
firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the TORQUE trimpot CW slowly until the
armature current is 150% of motor rated armature current.
7. Turn the speed adjust potentiometer CCW until the motor
stops.
8. Remove line power.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is
no longer needed.
39
IR COMP
The IR COMP trimpot setting determines the degree to which
motor speed is held constant as the motor load changes.
Use the following procedure to recalibrate the IR COMP setting:
1. Turn the IR COMP trimpot full CCW.
2. Set the speed adjust potentiometer until the motor runs at
midspeed without load (for example, 900 RPM for an 1800
RPM motor) A hand held tachometer may be used to measure
motor speed.
3. Load the motor armature to its full load armature current
rating. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP
trimpot until the motor runs at the speed measured in step 2.
If the motor does not maintain set speed as the load changes,
gradually rotate the IR COMP trimpot CW. If the motor
oscillates (overcompensation), the IR COMP trimpot may be
set too high (CW). Turn the IR COMP trimpot CCW to
stabilize the motor speed.
5. Unload the motor.
See Figure 17 (page 43) for recommended IR COMP settings.
40
ACCEL
The ACCEL setting determines the time the motor takes
to ramp to a higher speed. See Specifications on page 1 for
approximate acceleration times. ACCEL is factory set for the
fastest acceleration time (full CCW).
Use the following procedure to set the acceleration time:
1. Set the speed adjust potentiometer full CCW. The motor should run
at minimum speed (as set by the MIN SPD trimpot, page 37).
2. Turn the speed adjust potentiometer full CW and measure the
time it takes the motor to go from minimum to maximum
speed.
3. If the time measured in step 2 is not the desired acceleration
time, turn the ACCEL trimpot CW for a slower acceleration
time, or CCW for a faster acceleration time. Repeat steps 1
through 3 until the acceleration time is correct.
41
DECEL
The DECEL setting determines the time the motor takes to ramp
to a lower speed. See Specifications on page 1 for approximate
deceleration times. DECEL is factory set for the fastest
deceleration time (full CCW).
Use the following procedure to set the deceleration time:
1. Set the speed adjust potentiometer full CW. The motor should
run at maximum speed (as set by MAX SPD trimpot, page 37).
2. Turn the speed adjust potentiometer full CCW and measure the
time it takes the motor to go from maximum to minimum
speed.
3. If the time measured in step 2 is not the desired deceleration
time, turn the DECEL trimpot CW for a slower deceleration
time, or CCW for a faster deceleration time. Repeat steps 1
through 3 until the deceleration time is correct.
42
Torque Mode Calibration
Warning
TORQUE and MAX SPD trimpots must be recalibrated
every time the drive is switched between Speed and Torque
modes.
1. Disconnect power from the drive and connect a DC voltmeter
across the armature.
2. Set the MAX SPD and TORQUE trimpots to the 12 o’clock
position.
3. Set the external potentiometer to full CW.
4. Apply line power.
5. Adjust the TORQUE trimpot so the motor is running at the
motor’s maximum rated input voltage (nameplate rating).
6. Remove line power and the DC voltmeter. Be sure the motor
is firmly mounted. Connect a DC ammeter in series with the
armature. Carefully lock the motor armature.
7. Apply line power.
8. With the external potentiometer set to full CW, slowly adjust
the MAX SPD trimpot until the motor draws 100% of the
motor’s rated armature current (nameplate rating).
9. Remove the line power, stall from motor and ammeter.

RUN / JOG switch
Using a RUN / JOG switch is recommended in applications
where quick stopping is not needed and frequent jogging is
required. Use a single pole, two position switch for the
RUN / JOG switch, and a single pole, normally closed,
momentary operated pushbutton for the JOG pushbutton.
In the first wiring option, connect the RUN / JOG switch and
JOG pushbutton to the inhibit plug as shown in Figure 21. The
motor coasts to a stop when the RUN / JOG switch is set to JOG.
Press the JOG pushbutton to jog the motor. Return the
RUN / JOG switch to RUN for normal operation.

Leader-follower application
In a leader-follower application, use a PCM4 to monitor the speed
of the leader motor (Figure 23). The PCM4 isolates the leader
motor from the follower drive, and outputs a voltage proportional
to the leader motor armature voltage. The follower drive uses this
voltage reference to set the speed of the follower motor. An
optional ratio potentiometer may be used to scale the PCM4
output voltage.

Single speed potentiometer control of
multiple drives
Multiple drives can be controlled with a single speed adjust
potentiometer using a PCM4 at the input of each drive to provide
isolation (Figure 24). Optional ratio potentiometers can be used to

Reversing
A dynamic brake may be used when reversing the motor direction
(Figure 25). Use a three pole, three position switch rated for at
least the maximum DC armature voltage and maximum braking
current. Wait for the motor to stop completely before switching it
to either the forward or reverse direction. See the Dynamic
braking section, page 33, for recommended dynamic brake
resistor sizes

Reversing with a DIGI-LOK® controller
A DIGI-LOK® controller, model DLC600, can be used in a
reversing application. The DIGI-LOK® must be inhibited while
braking. Without the inhibit feature, the DIGI-LOK® will
continue to regulate. This will cause overshoot when the DIGILOK® is switched back to the drive.
Figure 26 shows the connection of the reversing circuit to a
MM23002 series drive and DLC600. Note: Only one DLC option
(Optical Encoder or Magnetic Pickup) may be used at a time.

Certificate of Compliance
Minarik Corporation hereby certifies that its MM23000 series
drives have been approved to bear the “CE” mark provided the
conditions of approval have been met by the end user.
The MM23000 series has been tested to the following test
specifications:
EN55011:1991 (emissions), and
EN50082-1:1992 (immunity)
Compliance allows Minarik’s MM23000 series to bear the
CE mark.
The end user, as described herein, falls into one of two categories:
1. The Consumer will deploy a stand-alone unit as an
integral, yet external, portion of the machine being
operated.
2. The Original Equipment Manufacturer (OEM) will
implement the product as a component of the machine
being manufactured.
In addition to EMI/RFI safeguards inherent in the MM23000
series’ design, external filtering is required.
64
Line filters
Minarik requires the Corcom® line filters listed below.
Table 3. Corcom® Filters
Nameplate Current of
Motor Wired to the Drive
0 to 4 amps
4.1 to 13 amps
Corcom® Filter
Part Number
6VV1
20VV1
The line filters should be wired to the AC line within 0.25 meters
of the drive. The ground connection from the line filter must be
wired to solid earth ground (resistance less than 500 ohms); not
machine ground. This is very important!
If the end-user is using a CE-approved motor, the correct line
filter listed above is all that is necessary to meet the EMC
directives listed herein.
65
Armature filters
If the end-user is not using a CE-approved motor, a second filter
on the armature must be deployed. This filter will have the
Minarik part number CEXXMM, where XX is the motor current
rating listed on the nameplate. Minarik® Filters are listed below.
Table 4. Minarik® Filters
Nameplate Current of
Motor Wired to the Drive
0 to 4 amps
4.1 to 13 amps
Minarik® Filter
Part Number
CE4MM
CE20MM
The filters listed above must be wired to the DC output of the
drive, as close to the drive as possible.
66
The end user must use the filters listed in this section to comply
with CE. The OEM may choose to provide alternative filtering
that encompasses the Minarik drive and other electronics within
the same panel.
The OEM has this liberty because CE is a machinery directive.
Whether or not every component in the OEM’s machinery meets
CE, the OEM must still submit his machine for CE approval.
Thus, no component must necessarily meet CE within the
machine, as long as the OEM takes the necessary steps to
guarantee the machine does meet CE. By the same token, even if
every component in the OEM’s machine does meet CE, the
machine will not necessarily meet CE as a machine.
Using CE-approved wiring practices (such as proper shielding)
and the filters listed in this section help the drive meet EN55011
(1991 emissions standard) and EN50082-1 (1992 immunity
standard).
Unconditional Warranty
A. Warranty
Minarik Corporation (referred to as "the Corporation") warrants that its products will be free
from defects in workmanship and material for twelve (12) months or 3,000 hours,
whichever comes first, from date of manufacture thereof. Within this warranty period, the
Corporation will repair or replace, at its sole discretion, such products that are returned to
Minarik Corporation, 901 East Thompson Avenue, Glendale, CA 91201-2011 USA.
This warranty applies only to standard catalog products, and does not apply to specials.
Any returns for special controls will be evaluated on a case-by-case basis. The Corporation
is not responsible for removal, installation, or any other incidental expenses incurred in
shipping the product to and from the repair point.
B. Disclaimer
The provisions of Paragraph A are the Corporation's sole obligation and exclude all other
warranties of merchantability for use, express or implied. The Corporation further disclaims
any responsibility whatsoever to the customer or to any other person for injury to the
person or damage or loss of property of value caused by any product that has been subject
to misuse, negligence, or accident, or misapplied or modified by unauthorized persons or
improperly installed.
C. Limitations of Liability
In the event of any claim for breach of any of the Corporation's obligations, whether
express or implied, and particularly of any other claim or breech of warranty contained in
Paragraph A, or of any other warranties, express or implied, or claim of liability that might,
despite Paragraph B, be decided against the Corporation by lawful authority, the
Corporation shall under no circumstances be liable for any consequential damages, losses,
or expense arising in connection with the use of, or inability to use, the Corporation's
product for any purpose whatsoever.
An adjustment made under warranty does not void the warranty, nor does it imply an
extension of the original 12-month warranty period. Products serviced and/or parts
replaced on a no-charge basis during the warranty period carry the unexpired portion of the
original warranty only.
If for any reason any of the foregoing provisions shall be ineffective, the Corporation's
liability for damages arising out of its manufacture or sale of equipment, or use thereof,
whether such liability is based on warranty, contract, negligence, strict liability in tort, or
otherwise, shall not in any event exceed the full purchase price of such equipment.
Any action against the Corporation based upon any liability or obligation arising hereunder
or under any law applicable to the sale of equipment or the use thereof, must be
commenced within one year after the cause of such action arises.
