3 Phase Voltage Monitor
WVM Series
Motor Protector

Description
The WVM Series provides protection against premature equipment (motor) failure caused by voltage faults on
the 3 Phase Line. The WVM’s microcontroller design provides reliable protection even if regenerated voltages
are present. It combines dependable fault sensing with a 10 fault memory and a 6 LED status display. Part
instrument, part control, the WVM protects your equipment when you’re not there and displays what happened
when you return. The WVM is fully adjustable and includes time delays to prevent nuisance tripping and
improve system operation. Time delays include a 0.25 to 30 s adjustable trip delay, an adjustable 0.25 to 64
m (in 3 ranges) restart delay, plus a unique 3 to 15 s true random start delay. The random start delay prevents
voltage sags caused by simultaneous restarting of numerous motor loads after a power outage.
Operation
ANSI Device #27/47/59
The output relay is energized when all conditions
are acceptable and the WVM is reset. A restart
and/or random start delay may occur before the
output relay is energized.
Field Adjustment: Select the line voltage listed
on the motor’s name plate. This automatically sets
the over and under voltage trip points. Consult the
equipment’s manufacturer specifications for the
correct trip delay, unbalance percentage, and restart/
reset operation and restart delay. Make connection
to all three line phases as shown in the connection
diagram. Apply power. If the relay fails to energize,
view the LEDs for the cause, and correct the problem.
If the phase sequence is incorrect, swap any two
wires. No further adjustment should be required to
achieve maximum equipment protection.
Read Memory: Fault(s) stored in the memory
are indicated when the yellow LED is flashing. To
read memory, rotate selector from Manual to Read
Memory. The last fault will be displayed. Repeat this
operation to read the second to the last fault. Repeat
until up to 10 faults are noted.
Memory Reset: To clear the memory of all
faults stored, rotate selector to Clear Memory
for 5 seconds. The yellow LED will turn off.
Memory Overload: The 11th fault causes the
first to be removed from memory. Only the 10
most recent faults are retained.
Random Start Delay: A new 3 to 15 s random start
delay is selected by the microcontroller when a fault
is corrected and when the operating voltage (L1, L2,
L3) is applied to the WVM. A random start delay does
not occur when the reset is manual.
Automatic Restart: Upon fault correction, the output
will re-energize after a random start delay.
Automatic Restart Upon Fault Trip: When a fault is
sensed for the full trip delay, the output de- energizes
and a restart delay is initiated. This delay locks out
the output for the delay period. Should the fault be
corrected by the end of the restart delay, the output
will re-energize after a random start delay. A restart
delay will also occur when operating voltage (L1, L2,
L3) is applied to the WVM.
Manual Reset: After a fault condition is corrected,
the WVM can be manually reset. There are two
methods; a customer supplied remote switch, or the
onboard selector switch.

Remote Reset: Reset (Restart) is accomplished
by a momentary contact closure across terminals 1
& 2. The output will immediately energize. Remote
switch requirements are ≥ 10 mA at 20 V DC and the
reset terminals are not isolated from line voltage. A
resistance of ≤ 20KΩ across terminals 1 & 2 will
cause immediate automatic restart.
Automatic Restart Upon Fault Correction:
(P/N includes an R)
When a fault is sensed for the full trip delay, the output
relay de-energizes. Upon correction of the fault, a
restart delay begins. At the end of this delay, the
output will re-energize after a random start delay. If
a fault occurs during restart timing, the restart time
delay will be reset to zero, and the output will not
energize until the restart delay is completed.
-60 Option: Add the suffix -60 to any automatic
restart part number to remove the Random Start
Delay feature. See example P/N‘s below.

Description
ANSI Device #27/47/59
Preliminary Data Sheet - Available 2nd Quarter 2007
The DLMU Series is a universal voltage, 3 Phase Voltage Monitor. It continuously measures the voltage of each
of the three phases with microcontroller accuracy and compares the value to preset trip points. It separately
senses Phase Reversal, Over, Under and Unbalanced voltages including Phase Loss and over or under frequency.
Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are
present. The unit trips within 200 ms when phase loss is detected. Adjustable time delays are included to prevent
nuisance tripping and short cycling of sensitive equipment. The 10A isolated DPDT output relay contacts trip
when a phase voltage exceeds the trip limits for the trip delay. Nominal line voltage, voltage unbalance, and
time delays are knob adjustable. The phase loss set point and the acceptable frequency range are fixed. Both
Delta and Wye systems can be monitored; no connection to neutral is required.
Operation
Upon application of line voltage, the output is deenergized and the restart delay begins. If all the three
phase voltages are within the acceptable range, the
Protects Against: Phase output energizes at the end of the restart delay. The
Loss, Phase Reversal, Over, Under and Unbalanced microcontroller circuitry automatically senses the vol
Voltages, Over/Under tage range, and selects the correct operating frequency
(50 or 60hz). The over and under voltage trip points
Frequency
are set at +/- 10% of the adjusted line voltage. When
35 mm DIN Rail or Surface the measured value of any phase voltage exceeds the
Mounting
acceptable range limits (lower or upper) the trip delay

Accessories
Restart Delay Options:
L= Lockout or minimum OFF time. The restart
delay begins when the output trips. The unit cannot
be re-energized until the restart delay is complete.
This provides a minimum off time or lockout time
to allow equipment sensitive to short cycling, time
to reset. If the fault is corrected after the restart
delay is complete the output energizes immediately.
The restart delay also occurs when line voltage is
applied/reapplied.
R= Restart Delay on fault correction. The restart
delay begins when line voltage is reapplied or
when a voltage fault is corrected. This option is
normally selected when staggered restarting of
multiple motors on a power system is required.
N= No Restart Delay. 0.6 second initialization
delay on application of line voltage applies.
Restart Notes:
All restart options remain reset when the following
conditions are detected:
1.) Phase Loss (phase unbalance greater than 25%)
2.) Average Line Voltage less than 120VAC
3.) Phase Reversal
The restart delay begins when the condition is
corrected.
LED Operation
The LED flashes green during the restart delay, then
glows green when the output energizes. It flashes
red during the trip delay then glows red when the
output de-energizes. It flashes red/green if phase
reversal is sensed If a fault is sensed during the
restart delay, the LED will glow red during that
portion or the full restart delay.

Description
The HLMU Series is a universal voltage, encapsulated, 3 Phase Voltage Monitor. It continuously measures the
voltage of each of the three phases with microcontroller accuracy and compares the value to preset trip points.
It separately senses Phase Reversal, Over, Under and Unbalanced voltages including Phase Loss and over or
under frequency. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. The unit trips within 200 ms when phase loss is detected. Adjustable time delays are
included to prevent nuisance tripping and short cycling of sensitive equipment. The 10A isolated DPDT output
relay contacts trip when a phase voltage exceeds the trip limits for the trip delay. Nominal line voltage, voltage
unbalance, and time delays are knob adjustable. The phase loss set point and the acceptable frequency range
are fixed. Both Delta and Wye systems can be monitored; no connection to neutral is required.
Restart Delay Options:
ANSI Device #27/47/59
L= Lockout or minimum OFF time. The restart
delay begins when the output trips. The unit cannot
be re-energized until the restart delay is complete.
This provides a minimum off time or lockout time to
allow equipment sensitive to short cycling, time to
reset. If the fault is corrected after the restart delay
is complete, the output energizes immediately.
The restart delay also occurs when line voltage is
applied/reapplied.
R= Restart Delay on fault correction. The restart
delay begins when line voltage is reapplied or
when a voltage fault is corrected. This option is
normally selected when staggered restarting of
multiple motors on a power system is required.
N= No Restart Delay. 0.6 second initialization
delay on application of line voltage applies.
Restart Notes:
All restart options remain reset when the following
conditions are detected:
1.) Phase Loss (phase unbalance greater than 25%)
2.) Average Line Voltage less than 120VAC
3.) Phase Reversal
The restart delay begins when the condition is
corrected.
Operation
Upon application of line voltage, the output is deenergized and the restart delay begins. If all the three
phase voltages are within the acceptable range, the
output energizes at the end of the restart delay. The

Connection
Upon application of power, a 0.6 s random start delay
begins and the PLMU measures the voltage levels
and line frequency and selects the voltage range. The
output relay is energized and the LED glows green when
all voltages are acceptable and the phase sequence
is correct. LED flashes green during trip delay,
glows red when output de-energizes. Undervoltage,
overvoltage, and voltage unbalance must be sensed
for continuous trip delay before the relay de-energizes.
Re-energization is automatic upon fault correction.
The output relay will not energize if a fault condition is
sensed as three phase input voltage is applied. Line
voltage is selected with the knob, setting the over and
under voltage trip points. Voltage range is automatically
selected by the microcontroller.

IEEE C62.41-1991 Level B
Upon application of line voltage, the restart delay
begins. The output is de-energized during restart delay.
Under normal conditions, the output energizes after the
restart delay. Undervoltage, overvoltage, and voltage
unbalance must be sensed for the complete trip delay
period before the output de-energizes. The restart
delay begins as soon as the output de-energizes. If
the restart delay is completed when a fault is corrected,
the output energizes immediately. The output will
not energize if a fault is sensed as the input voltage
is applied. If the voltage selector is set between two
voltage marks (e.g. between 220 and 230 V), the LED
will flash red rapidly. The TVW provides fault protection
at the lower of the two line voltages (e.g. 220 V).
Reset: Reset is automatic upon correction of a fault.
LED Operation
The LED flashes green during the restart delay, then
glows green when the output energizes. It flashes
red during the trip delay then glows red when the
output de-energizes. It flashes red/green if phase
reversal is sensed. If the voltage selector knob is
between settings, it rapidly flashes red.

Description
Provides protection for motors and other sensitive loads. Continuously measures the voltage of each of
the three phases using a new microcomputer circuit design that senses under and over voltage, voltage
unbalance, phase loss, and phase reversal. Protection is provided even when regenerated voltages are
present. Includes a trip delay to prevent nuisance tripping and a restart delay to prevent short cycling after
a momentary power outage.

IEEE C62.41-1991 Level B
Upon application of line voltage, the restart delay
begins. The output relay is de-energized during restart
delay. Under normal conditions, the output energizes
after restart delay. Undervoltage, overvoltage, and
voltage unbalance must be sensed for continuous
trip delay period before the output is de-energized.
The output will not de-energize if a fault is corrected
during the trip delay. The restart delay begins as soon
as the output relay de-energizes. If the restart delay is
completed when the fault is corrected, the output relay
will energize immediately.
The output relay will not energize if a fault or phase
reversal is sensed as three phase input voltage is
applied.
Reset: Reset is automatic upon correction of a fault.
Connection
LED Operation
The LED flashes green during the restart delay, then
glows green when the output energizes. It flashes
red during the trip delay then glows red when the
output de-energizes. It flashes red/green if phase
reversal is sensed.

Description
The PLR Series provides a cost effective means of preventing 3 phase motor startup during adverse voltage
conditions. Proper A-B-C sequence must occur in order for the PLR’s output contacts to energize. In addition,
the relay will not energize when an undervoltage or phase loss condition is present. The PLR protects a motor
against undervoltage operation. The adjustment knob sets the undervoltage trip point.
Operation
US Patent No. 6541954
ANSI Device # 27/32
Protects Against: Phase
Loss (On Startup), Phase
Reversal, Undervoltage
Used Where Moderate Voltage Unbalance Protection is Not Required
Direct Replacement for Most Popular 3 Phase Monitors
8 Pin Octal Base Connection
SPDT Isolated 5 A Relay Contacts
AMSE A17.1 rule 210.6
NEMA MG1 14:30, 14:35
IEEE C62.41-1991 Level B
The output relay is energized and the LED glows when
all voltages are acceptable and the phase sequence
is correct. Undervoltage must be sensed for a
continuous dropout delay period before the relay deenergizes. Reset is automatic upon correction of the
fault condition. The output relay will not energize if a
fault condition is sensed as power is applied.
Connection
Field Adjustment: Turn the adjustment knob fully
counterclockwise and apply three-phase power.
The LED should be ON. Increase adjustment until
the LED goes OFF. Decrease adjustment until LED
glows again. If nuisance tripping occurs, decrease
the adjustment slightly.
NOTE: When properly adjusted and operating in
an average system, a voltage unbalance of 10% or
more is required for phase loss detection. When a
phase is lost while the motor is running, a voltage
will be induced into the open phase nearly equal in
magnitude to the normal phase-to-phase voltage.
This condition is known as regeneration. When
regenerated voltages are present, the voltage
unbalance during single phasing may not exceed
10% for some motors. The PLR Series may not
provide protection under this condition. For systems
that require superior phase loss protection, select
the PLMU Series.

Description
The HLV Series is a single phase undervoltage monitor designed to protect sensitive equipment from brownout
or undervoltage conditions. Time delays are included to prevent nuisance tripping and short cycling. The 30 A,
1 hp rated SPDT relay contacts allow direct control of motors, solenoids and valves. The output relay can be
ordered with isolated SPDT contact to allow monitoring of one voltage and switching a separate voltage. Two
undervoltage trip point ranges allow monitoring of 110 to 120 VAC or 208 to 240 VAC systems.

Upon application of input voltage the output relay remains de-energized. When the input voltage value is
above the pull-in voltage, the restart delay begins. At
the end of the restart delay, the output relay energizes. When the input voltage falls below the trip point,
the trip delay begins. If the input voltage remains
below the pull-in voltage for the entire trip delay the
relay de-energizes. If the input voltage returns to a
value above the pull-in voltage, during the trip delay,
the trip delay is reset and the relay remains energized.
If the input voltage falls below the trip point voltage
during the restart delay, the delay is reset and the
relay remains de-energized. Reset is automatic upon
correction of an undervoltage fault.
Reset: Removing input voltage resets the output
relay and the time delays.

KVM Series
Single Phase
Undervoltage Monitor
Description
The KVM Series is a single phase undervoltage monitor designed to protect sensitive equipment against
brownout undervoltage conditions. The compact design and encapsulated construction make the KVM an
excellent choice for OEM equipment.
Operation
Function
The output relay is energized and the LED glows
green when the input voltage is above the reset
voltage threshold. If the input voltage drops below the
undervoltage set point, the output relay and LED will
de-energize. The output relay will remain de-energized
as long as the input voltage is below the reset voltage.
Reset is automatic when the input voltage returns to a
normal range.
