General description i-ALERT™ Condition Monitor
Description
The i-ALERT Condition Monitor is a compact, battery-operated monitoring device that continuously
measures the vibration and temperature of the pump power end. The condition monitor uses blinking red
LEDs to alert the pump operator when the pump exceeds pre-set vibration and temperature limits. This
allows the pump operator to make changes to the process or the pump before a catastrophic failure
occurs. The condition monitor is also equipped with a single green LED to indicate when it is operational
and has sufficient battery life.
Alarm mode
The condition monitor enters alarm mode when either vibration or temperature limits are exceeded over
two consecutive readings within a ten minute period. Alarm mode is indicated with two red flashing LEDs
within two second intervals.
Temperature and vibration limits
Variable Limit
Temperature 195°F (91°C)
Vibration 100% increase over the baseline level
Battery life
The i-ALERT Condition Monitor battery is not replaceable. You must replace the entire unit once
the battery runs out of power.
The battery life is not covered as part of the standard five-year pump warranty.
This table shows the average condition monitor battery life under normal and alarm-mode operating
conditions.
Condition monitor operational state Battery life
Normal operating and environmental conditions Three to five years
Alarm mode One year

Preinstallation
Precautions
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is properly certified.
• You must earth (ground) all electrical equipment. This applies to the pump equipment, the driver, and
any monitoring equipment. Test the earth (ground) lead to verify that it is connected correctly.
NOTICE: Supervision by an authorized ITT representative is recommended to ensure proper installation.
Failure to do so may result in equipment damage or decreased performance.
Pump location guidelines
WARNING:
Assembled units and their components are heavy. Failure to properly lift and support this equipment can
result in serious physical injury and/or equipment damage. Lift equipment only at the specifically identified
lifting points. Lifting devices such as eyebolts, slings, and spreaders must be rated, selected, and used for
the entire load being lifted.
Installation
Guideline Explanation/comment
Keep the pump as close to the liquid source as
practically possible.
Make sure that the space around the pump is
sufficient.
If you require lifting equipment such as a hoist or
tackle, make sure that there is enough space above
the pump.
Protect the unit from weather and water damage
due to rain, flooding, and freezing temperatures.
Do not install and operate the equipment in
closed systems unless the system is constructed
with properly-sized safety devices and control
devices.
Take into consideration the occurrence of
unwanted noise and vibration.
This minimizes the friction loss and keeps the suction
piping as short as possible.
This facilitates ventilation, inspection, maintenance,
and service.
This makes it easier to properly use the lifting
equipment and safely remove and relocate the
components to a safe location.
This is applicable if nothing else is specified.
Acceptable devices:
• Pressure relief valves
• Compression tanks
• Pressure controls
• Temperature controls
• Flow controls
If the system does not include these devices, consult
the engineer or architect in charge before you operate
the pump.
The best pump location for noise and vibration
absorption is on a concrete floor with subsoil
underneath.
If the pump location is overhead, undertake
special precautions to reduce possible noise
transmission.
