Bell & Gossett P2000642B i-ALERT Condition Monitor - Manual (Page 12)

i-ALERT ™ Condition Monitor routine operation
Measurement interval
This table shows the measurement intervals for the condition monitor during normal
operation and when the monitor is in alarm mode.
Mode Measurement interval
Normal operating mode Five minutes
Alarm mode Two minutes
When the condition monitor measures a reading beyond the specified temperature and
vibration limits, the appropriate red LED flashes. After the process or pump condition that
causes the alarm is corrected, the condition monitor returns to normal mode after one
normal-level measurement.
Alarm mode
When the condition monitor is in alarm mode, you should investigate the cause of the
condition and make necessary corrections in a timely manner.
Magnetic device considerations
Be careful when you use magnetic devices in close proximity of the condition monitor,
such as magnetic vibration-monitoring probes or dial indicators. These magnetic devices
can accidentally activate or deactivate the condition monitor resulting in improper alarm
levels or loss of monitoring.
Deactivate the i-ALERT ™ Condition Monitor
NOTICE: Always deactivate the condition monitor when the pump is going to be shut
down for an extended period of time. Failure to do so will result in reduced battery life.
1. Touch and hold a small magnet to the condition monitor over the ITT logo until the red
LEDs blink three times.
This should take 10-15 seconds if the condition monitor is in normal operating mode
and approximately five seconds if the condition monitor is in alarm mode.
2. Remove the magnet.
If the deactivation is successful, solid red LEDs will be displayed.
Reset the i-ALERT ™ Condition Monitor
NOTICE: Always reset the condition monitor when the pump is started after maintenance,
system change, or down-time. Failure to do so may result in false baseline levels that could
cause the condition monitor to alert in error.
Touch a magnet to the condition monitor over the ITT logo to turn the power on.
The condition monitor begins to establish a new baseline vibration level.
