The display shows messages about the device typeand software version. After the initializing procedure the converter displays the process values in the working level.Operating of the device is arranged in 2 levels. The requested parameter can be called by the button . Selection withina parameters or entering data, use buttons and . Parameters are stored zero voltage safe in the EEPROM.The configuration level is called up by pressing the buttoncan be programmed.. Now all parameters defining the function of the converterAfter finishing the configuration or if longer than 120 seconds no button was pushed, the program returns to the workinglevel. Leaving the configuration level is possible at any time by pushing the button for 2 seconds.Installation note!Before the device can be used, it must be configurated for the intended use.- 7 -
