Filter monitor box

The Filter Monitor Box allows remote filter monitoring. It evaluates the signals from a filter monitor, as well as from an ECO Drain condensate drain, and can pass messages to a central maintenance control system via two alarm contacts.

Group alarm (volt-free contact)

• Indication of (time-controlled) service interval for filter element change
• Indication of optimum time for filter element change computed by microprocessor- aided measurement value processing
• Maximum differential pressure exceeded (2 minute delay)
  

Safety alarm (volt-free contact only active in active safety mode)

• Maximum differential pressure exceeded (5 second delay)

The power supply for the filter monitor and ECO-Drain is provided by the Filter monitor box.
