E/One Sentry PreSTAT

E/One Sentry PreSTAT provides advance warning of pending service needs by monitoring major operating conditions. A Trouble indication is provided when these conditions fall outside of normal ranges, although the grinder pump station may continue to operate.


The E/One Sentry PreSTAT feature provides predictive status monitoring of:

  • AC input voltage — if input voltage falls below 88 percent or rises above 112 percent of normal line voltage, a Trouble indication is provided
  • Amperage — if amperage exceeds preset limits, a Trouble indication is provided
  • Pump run time — if the pump operates for extended periods (adjustable), a trouble indication is provided

PreSTAT offers a new standard of reliable and uninterrupted service through better asset management.
