Advanced soft starting, motor protection and application control with expandable Smart Card capability.
Like its predecessor, the AuCom EMX4 Soft Starter sets new standards for soft start technology. The AuCom EMX4 is not only smaller, more powerful and packed with new control and protection features, it also introduces the game-changing Smart Card capability. Fitting a Smart Card to the AuCom EMX4 transforms it from super smart motor controller to complete system controller. This is truly a starter for the future.
The AuCom EMX4 includes starter, motor and system protection functions, complete with alarms to alert you to any potential issues. In the event that the worst does happen, Power Through and Emergency Run functions give you the power to choose to keep running.

The EMX4i can be used in a six wire configuration, sometimes referred to as inside delta, but there are constraints.
The current rating when connected in inside delta is equal to the 3 wire ratings times 1.5. There are some that will suggest root 3, which would be correct for the continuous current, but the ratings are primarily determined by the start current, not the continuous run current. During start, the conduction angles are much lower than in 3 wire connection, so a higher current for a shorter time is more heat for same average current.
Because the soft starter phases are in series with the motor windings, it is imperatie that a contactor is used to isolate the windings from the supply.
The AuCom EMX4 is an advanced motor soft starter designed for controlled motor starting and stopping, motor and system protection, communications and application-specific control. Its expandable Smart Card capability allows additional functions to be added for selected industries and control requirements.
The EMX4 is suited to demanding fixed-speed motor applications where advanced control, protection or system integration is required. Typical duties include pumps, conveyors, irrigation systems and other industrial motor-driven equipment.
The EMX4 combines advanced soft-start control with motor and system protection, communications, flexible I/O and Smart Card expansion. For applications that do not require continuous speed control, the soft starter provides controlled starting and stopping without the continuous conversion losses associated with a VFD.
The EMX4 Pump Card is an optional smart card for the EMX4 soft starter that adds additional IO and logic to enable the EMX4 to provide an enhanced suite of pump control functionality.
Auto Start/Stop : The pump is run automatically depending on changes in pressure, well/pond depth or based on preprogrammed timing schedules.
System Protection : The pump is protected against abnormal operation and premature failure due to pressure, flow and dry run errors.
Integrated Control : The pump card combines pump performance monitoring, protection and automation into the EMX4 soft starter control system.
A Smart Card is an expansion option that adds application-specific or industry-specific functionality to the EMX4. This can allow the soft starter to perform additional control and monitoring tasks and may simplify system design and integration.
Yes. The EMX4 includes motor, starter and system protection functions together with alarms and operational features designed to help manage abnormal conditions.
Communication options shown for the EMX4 include DeviceNet, Modbus, Profibus, ProfiNET and Ethernet, allowing integration into common industrial automation networks.
