ISO 2858 conformance
The Models 3185 and 3186 conform to the ISO 2858 Standard where applicable. The ISO standard allows
for 125 mm flanges, which are nominal 5 in. flanges. Because ANSI standards no longer permit 5 in.
flanges, they are not used on models 3185 and 3186.
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
