NOTE: VR25-H, VR30-M and VR30-H have one status relay, used to signal pump operation or malfunction.
All other models have two relays. See table following for functionality.
The communications module has a built in web server which allows you to access your pump directly from an existing
Ethernet network. Direct connection to a computer is also possible with a crossover cable.
The web server uses HTML pages to set/view:
• Regulation mode settings
• Regulation parameters (power, RPM, head, ow, eciency)
• Relay settings
• External control inputs
• Current and previews error
• Pump statistics (power consumption, run time and other).
