Other Relevant Documentation or Manuals
• When using dual trip power monitors, select high and low trip points designed to protect
your specific system within the recommended pump operating region that is defined by
ITT. This method creates boundaries for a safe pump operating envelope.
• Set the nuisance trip feature for each power trip. Set the nuisance trip device to an interval
that allows the system to experience momentary fluctuations in power draw. Set it during
an appropriate time-frame that prevents the pump from experiencing excessive heat or
dangerous operating conditions.
• Set the delay timer for start-up conditions that allow the system to come to normal
operating power within a time-frame that maximizes protection of your pump.
• For variable speed operation, consult ITT or the power monitor manufacturer for
appropriate auxiliary devices that are designed for operating at multiple speeds or
fluctuating frequencies.
• Select an electrical enclosure that is suitable for the operating environment, or install the
unit in an appropriate electrical panel.
• Do not activate the manual override of the power monitor until a thorough examination of
the source of the problem is defined and corrected.
• Investigate and select power monitor features that are most suitable for your particular
application and plant safety.
