If text/data refers only to specific devices, this will be clearly indicated in the text and one of the above designations used. - Page 6 − When cleaning, ensure that no liquid gets into the device or connections. Residual risks The scope of supply and performance of the MP85A process controller covers only a small area of measurement technology. In addition, equipment plan- ners, installers and operators should plan, implement and respond to the safety engineering considerations of measurement technology in such a way as to minimize remaining dangers.

MP85A process controller 6.6 Measurement programs (parameter sets) A total of 31 measurement programs can be activated from the MP85A process controller’s internal (flash) memory for 31 different workpieces. A measurement program comprises a workpiece-specific parameter set consisting of the settings of the amplifier for the sensor technology, measure- ment acquisition and storage, function assignments of the digital inputs/ outputs and the evaluation methods. - Page 59 If the parameter sets from the internal Flash-EPROM are used, the system parameters are identical for all 31 Flash parameter sets and only present once in the MP85A process controller. If parameter sets from the MMC/PC card or from PC are used, the system parameters are a component of the respective parameter set and can therefore be different.
