Page 4: Introduction
The EnviroStart is a high specification digital Soft-Start, Motor Energy Control available in models suitable for motors up to 15A. In addition to the provision of a soft-start, the EnviroStart MEC incorporates state of the art Motor Energy Control technology to substantially reduce the electricity consumption of synchronous electric induction motors whilst they are operating at less than their full load capacity. -
Page 5: Correct Envirostart Selection
EnviroStart is expected to operate outside the normal specifications and you are uncertain as to the selection of a unit please contact EMS (European) or your local Distributor, we will always be happy to assist to ensure your application is correctly supported. -

2. The power should be disconnected before installation and only put back on once installation is complete. 3. The only motors for which the Single Phase EnviroStart is suitable are 110v AND 220V AC single-phase induction motors. (Also known as “Cage” or “Squirrel Cage” motors). EnviroStart cannot be used on DC motors, Switched Reluctance motors or any form of Three Phase motor. -

4. INSTALLATION 4.1 GENERAL PROCEDURES The majority of 4A and 10A Single Phase EnviroStart units will be shipped pre-wired with five core cable suitable for the current rating of the unit. If this is the case then ignore the following section as it is not relevant to your installation. (Refer to the wiring diagram at the end of this Installation and Commissioning Guide for details of the cable connections). -

Earth 4.2 SETTING UP All EnviroStart DIP Switches are polled continuously and it should be possible to make changes whilst the unit is running to change between operational modes. It is however good practice to make changes whilst the unit is switched off to ensure that the software is not “hung”... -

4.3.5 REFRIGERATION APPLICATION SETTING In all cases where EnviroStart is fitted to refrigeration compressors, a minimum period of two minutes should elapse between stopping and starting the compressor motor. This is to allow the system to shed its backpressure. In many systems such as those manufactured by... -

If you experience problems with the unit re-starting in such conditions then use the inbuilt timer feature of EnviroStart by switching DIP 6 into the “ON” position. This will cause the unit to always wait two minutes before a restart is allowed ensuring backstop pressures are equalized within the compressor circuit. - Page 16 Single Phase Motor Energy Control - Page 16 of 20...
