Additional to the Easy Engine® user information and Help File this addendum informs users about several user and performance issues of Easy Engine®.

NOTE: Any data communication failure or interruption during the monitoring of blocks will not affect the current run. If for whatever reason your computer with Easy Engine installed crashes, the connected PTC-200/221/225 DNA Engine will continue and finish the current run normally.

The user interface of Easy Engine® uses the Right Mouse button for showing the Context Menu. This way users will gain access to program operations. See figure I : The Easy Engine Context Menu.

Easy Engine® is designed and tested for reliable use with PTC-200/221/225 DNA Engine software version 3.0B or higher. For optimal performance of Easy Engine it is recommended that every PTC-200/221/225 software version lower than 3.0B is upgraded. Please contact your local MJ Research Distributor for upgrade possibilities. Using Easy Engine with PTC-200/225 DNA Engine software versions lower than 3.0B can give unpredictable data and results. Using software version 3.0A is a very special occasion and is therefore NOT recommended

Running a "GRADIENT" step on a block type other than a "96V" Alpha Unit can give unpredictable results. Therefore it is not recommended to start a protocol with a "GRADIENT" step on an Alpha Unit other than "96V".

In case of using Easy Engine in combination with a "Twin Tower" Alpha Unit, the Heated Lid temperature and the corresponding line in the monitoring graph indicates "-20°C". This value indicates that no Heated Lid is installed on this specific Alpha Unit.

To guarantee a continuous flow of data communication and processing of Easy Engine it is recommended that Easy Engine users should avoid lots of "Windows Multi Tasking" during monitoring blocks or servicing blocks. Multi-tasking means starting or working in other programs than Easy Engine.

It is not recommended to use a "Flat Block" Alpha Unit in "Calculated" control mode. It can give unpredictable results. If an Easy Engine user designs or edits a protocol for use with a "Flat Block" Alpha Unit it is recommended to use the "Block" Control Method.
