Event logging:

• The VMX-synergy™ data logger records all events, allowing for fast, reliable fault analysis and resolution.
• Recording various activities such as start, stop, top of ramp, faults, application parameters (time, overload level, currents, frequency), and device information.
• Event logs can be obtained by using a USB port or VMX-synergy™ commissioning software.

Soft stopping:

• Water hammers can be eliminated with Soft Stop Control.
• When you activate the stop signal, your pump motor's output torque gradually decreases.
• Check valves are now softly shut, and other parts of the fluid system are spared the force and potentially catastrophic effects of a water hammer.
