8. Industry Issues
 Voltage
 Low Voltage
 A long reduction in voltage, for example, the heavy
usage of air conditioning during summer could lead
to low voltage or brownouts and cause
 Equipment shutdowns
 Reduced motor torque, increased stalling
 Overheating of motors (insulation breakdown)
 Tripping of protective devices
 High Voltage
 Electronic and electrical devices are designed to
operate at a certain maximum supply voltage
 Considerable damage can be caused by voltage that
is higher than that for which the devices are rated

9. Industry Issues
• Phase Loss / Phase Reversal
• Can occur from lightening, down power lines, blown
fuse, wiring error or contactor failure
• This causes motor windings to over heat and
prevents the motor from operating at its rated horse
power

10. Industry Issues
Voltage Imbalance • Voltage Unbalance
• Voltage unbalance - a voltage unbalance
between the three phases. Possible causes,
• Lines are lost
• A tin can transformer is replaced by another
model
• A contactor becomes worn
A power outage, caused by
high winds, affected 150,000
• A new load is added to one phase of a facility’s
customers in eight counties power system
north and east of Houston. A
spokesman with Entergy Texas
said 16 transmission lines were
• A slight voltage unbalance causes a significant
lost, which caused a voltage temperature increase and causes premature
unbalance and led to the
emergency shutdown of a failure
power plant in Willis, about 45
miles north of Houston.

33. Key Features - Benefits
1. REAL-TIME 3 LINES VOLTGAGE AND CURRENT
• This is a real time screen to read if one line is out of balance.
2. REAL-TIME 3 CURRENT LEVELS
• Currents on lines 1, 2 & 3 with average between the three lines
displayed.
3. REAL-TIME 3 VOLTGAGE LEVELS
• Incoming voltage levels on Lines 1-2, 2-3 and 3-1 with average
between the three lines displayed.
4.CURRENT & VOLTGAGE UNBALANCE
• Indicates the unbalance percentage of the current the motor is running
at and the incoming line voltage.
5. RESTART DELAY TIMERS
• This display shows the time left to reset, if the 777 has tripped on a fault
6. GROUND FAULT CURRENT AMPS
• Displays the amount of ground fault, in amps. This helps guard
against ground faults that could lead to premature motor failure
overtime.

34. Key Features - Benefits
7. ACCUMLATIVE HOURS AND ENERGY
• This displays the accumulative hours of operation (when the motor is
running) and the energy used in KW hours. This screen feature helps
one to schedule maintenance for the motor and/or driven equipment.
8. # OF FAULTS AND # OF TRIPS
• This display feature shows the number of actual starts the motor has
had and the number of times the unit tripped on a current fault.
9. VOLTAGE, CURRENT, POWER FACTOR
• This screen shows the average of the voltage and current and power
factor.
10.POWER CONSUMTION
• The actual power consumption is displayed as well as the KVARS.
11. PENDING FAULT
• This screen will ‘pop up’ and display at anytime when a pending fault
problem may be occurring. The unit displays multiple fault indications
such as Voltage and Current unbalance, etc. and captures relevant
data like date and time.

35. Key Features - Benefits
12. FAULT 2
• This shows the Current Unbalance when a fault occurs along with the
day and time the fault occurred.
13. FAULT 2 was a CURRENT UNBALANCE
• This display indicates the current levels at the time of the fault. If we
did the math, we would see that the unbalance was at 23%. We had
our CUB set at 10% and #RF at 0. We determined that we had a faulty
contactor, thus we stopped a current single phase from burning up the
motor.
14. FAULT 2
• This screen shows that at the time of the fault, we had .09A of ground
fault current, which will happen when you have a current unbalance.
15. FAULT 2
• This screen shows that the voltages at the time of the fault were
balanced, so the fault was on the load side of the contactor.
16. FAULT 2
• This screen displays the voltage unbalance (0%) and the average
voltage for the unit.
17. FAULT 2
• This screen displays the current unbalance (0%) and the average
current for the unit.

 Displays current and voltages
 Displays fault condition
 Remote reset of MotorSaver/PumpSaver
 Standard communication port
 Displays run hours on each motor

38. 777-KW/HP Competitive Advantages
 Under-Power Tripping – Being able to trip on under-power instead of
under-current means a more accurate and faster trip – meaning better
protection to the motor. This is particularly advantageous to pumps
where their running dry can cause pump damage. Most of our
competition trips on under-current only, or does not offer under-current
tripping at all.
 Advanced Motor Protection Affordably – This unit provides motor
protection from the primary causes of damage due to electrical issues.
These include voltage, phase, current and ground fault monitoring. In
addition it provides a display for monitoring voltage & current and
communications to monitoring systems. Most of our competition offering
these protection features are at MUCH higher price points (often 3 to 5
times our price or more).
 Multiple Communication Options – When the user wants to monitor their
motors/pumps via SCADA or other software, this unit provides multiple
protocols to make integration easy. These include Modbus RTU,
Profibus, DeviceNet, and Ethernet Modbus TCP. Most of our competition
offers no communications or perhaps only 1 or 2 of these options.
 Networking: Up to 99 units can be networked together and 16 units can
be on a sub-network via one remote monitor.

 This microcontroller-based
voltage and phase-sensing
device constantly monitors
the 3-phase voltages to
detect harmful power line
conditions.

45. 460 & 201A-AU Advantages
 Universal Voltage – Being able to set our unit to work on voltages from
190-480V means that the user only needs to worry about 1 unit type for
replacement purposes on both 230V and 460/480V applications, the local
distributor only needs to keep 1 on the shelf, the service techs only need
to have 1 unit type on their truck, etc. Most of our competition requires
two separate units for these different voltage ranges.
 Diagnostic LED – instead of just telling the user that the unit has tripped,
we help the user determine the cause of trip so that they can solve the
problem. Most of our competition only tells you that the unit has tripped,
but not why.
 More User Adjustability – Different applications and installation sites can
have unique issues. Being able to adjust the trip delay, restart delay and
trip set point for the voltage unbalance means the end user can set these
for that location’s unique needs. Most of our competition has fixed set
points for these things.
 No line-side fuses required – Our units are UL approved without the
requirement for line-side fuses to protect our unit. Most of our
competition require these fuses, which adds further cost to the project.

 Loss of any phase (single-phasing) on the load
or line side
 Low and high voltage
 Voltage unbalance (adjustable)
 Phase reversal
455 list price is $223.17

48. 455 Advantages
 Contactor Failure Protection – By having a second set of voltage
inputs to monitor the three legs of voltage between the contactor
and the motor, the 455 is able to sense and trip on unbalanced
voltage being caused by wearing contacts on the contactor. This
unbalanced voltage over time will cause damage to the motor,
and as the contacts continue to wear they can eventually fail and
cause a single phase condition, which will quickly burn up
motors. Most of our competition does not offer this protection
feature.
 Fault History Memory – This unit keeps a history of the past 20
fault causes, including voltage and unbalance at the time of trip.
By using our Informer-MS service technicians can easily
determine why the unit has been tripping, and solve the problem.
This is particularly valuable for motors/pumps that are in remote
locations where there is no personnel on-site to see the unit’s
LED to determine trip cause. Most of our competition does not
have this fault history capability.

16MA1A0 PC-100-LLC-GM
Series 16M as opposed a different word (like
16MB1A0 PC-100-LLC-GM
equivalent to) because we don’t replace every
unit in their 16M series. This is primarily 16MC1A0 PC-100-LLC-GM
because we only offer an adjustable 4.7K- 16MD1A0 PC-100-LLC-GM
100K sensitivity range and two voltage ranges 16ME1A0 PC-100-LLC-GM
(95-120 and 190-240), and we avoided the 16MA2A0 PC-200-LLC-GM
time delay options other than a fixed 2 second 16MB2A0 PC-200-LLC-GM
debounce trip delay time. 16MC2A0 PC-200-LLC-GM
16MD2A0 PC-200-LLC-GM
We cross to their 120v and 230v products, and we have the 16ME2A0 PC-200-LLC-GM
sensitivity range from 4.7k to 100k, so we support the A-E and K-P 16MK1A0 PC-100-LLC-GM
versions. They sell their controls with a fixed probe sensitivity.
16ML1A0 PC-100-LLC-GM
A=4.7k, B=10k, C=26k…E=100k for what we would call pump-
16MM1A0 PC-100-LLC-GM
down operation, and K=4.7k, L=10k…etc. for pump-up operation.
16MN1A0 PC-100-LLC-GM
Our LLC products allow pump-up or pump-down to be selected
16MP1A0 PC-100-LLC-GM
using the pot, as well as the sensitivity setting.
16MK2A0 PC-200-LLC-GM
Essentially this means that our 2 units can 16ML2A0 PC-200-LLC-GM
16MM2A0 PC-200-LLC-GM
replace 20 of theirs due to our unit's adjustability. 16MN2A0 PC-200-LLC-GM

54. Intrinsically Safe
Relays Overview

55. Intrinsically Safe (IS) Products
 IS products are considered an “intrinsically safe associated
apparatus.”
 Our products can be applied to the most hazardous
environments, but the electronics must be located in a
“nonhazardous” location.
 Essentially, we can run the IS wiring to the hazardous
locations, but the electronics must either be located in a
panel that is not in the hazardous area, or in an explosion
proof enclosure in the hazardous area.
 We supply control drawings with each product that add
clarity for an application.
Various Models and the list price ranges from $169 up to $670

62. ISS-105 Advantages
 Combine multiple products – This unit combines the functions of
an alternating relay (for 2, 3 or 4 pump systems), intrinsically safe
switches, and other associated relays. No other competitive
product offers all this functionality in 1 unit.
 Reduce panel size – By combining all these products into one,
less panel space is needed for components. A smaller panel size
means cost savings.
 Reduce production/wiring time – combining these components
means less things to wire up, which means less time spent per
panel. This means labor savings and quicker turn-around time on
panel production.
 IS products meet the 6th edition of UL913. Many products that
are being sold today only meet an earlier version of the standard.

64. Alternating Relays

65. Alternating Relays
Model ALT alternating relays are used to alternate between
two loads. The ALT is commonly used in duplex pumping
applications to balance the runtime of both pumps.
 Two LEDs indicate the energized load.
 Can be ordered with a switch to manually
 override the system.
 Three choices of input voltage provide the
 versatility needed to handle global applications.

68. Load Sensors

69. LSR-0
The Model LSR-0 is a self-powered load sensor
intended for use as a proof relay. It is used to verify
that current is flowing as intended. It has a
guaranteed 15A pull-in current and 2.5A drop-out
current. Proof relays are typically used to interlock
fans, compressors, motors, heating elements and
other devices. The LSR-0 is self-powered, that is, it
draws its power from the wire being monitored so it
does not require separate control power wiring.

70. LSR-24, -115 & -230
The Model LSR-XXX load sensors use current levels
to determine feed rates, tool wear, loss of prime on
pumps, mixer viscosity and all types of overload and
underload conditions. They may also be used to stage
pump motors, chillers and other machinery. These
devices combine a current transformer (CT) with Form
C (SPDT) relay contacts to switch alarm circuits,
contactors or any resistive or inductive load. One
simple screwdriver adjustment will calibrate the sensor
for all single-phase or 3-phase applications up to Switches loads based
100hp. on current level changes
associated with:
•Motor failure
•Belt loss
•Broken shaft
•Bearing failure
•Heating element failure
•Load loss on fans
or pumps

71. LSRU
The Model LSRU is a microcontroller-based family of load
sensors that employ three basic types of control logic:
Motor Control Logic
Combinations of functions including overcurrent and undercurrent
or either overcurrent or undercurrent with variable trip, restart or
extended restart delay settings.
Alarm Logic
The LSRU-AL simply indicates whether the current is between
the setpoints or outside of the setpoints.
Feed Control
The LSRU-FC is a load monitor intended to control feeder
mechanisms in a variety of applications. It stops the feeder when
the grinder, chipper, saw, auger, etc. nears overload.

72. LSRX & LSRX-C
The Model LSRX is an AC current sensor
designed to energize the output contact
whenever 4.5 Amps or greater is present. The
LSRX is used commonly as an AC current proof
relay to indicate if a motor is operating. It can
also be used to interlock fans, compressors
and motors; to indicate equipment status such
as feed rates, tool wear, loss of prime on pumps,
mixer viscosity and all types of current sensing
conditions or to stage pump motors, chillers, or Compact design saves precious panel
other machinery. space.
Relay contacts can switch
up to 480VA @ 240VAC, 5A
continuous. Unique LED indicator gives
clear visual status of relay state.
Fast-on terminals or optional
depluggable screw terminals ensure
quick, simple connections.
Requires no external power, power is
induced from the AC conductor.
