Setup
4.6.1 Adjustable threshold for undervoltage alarms US1 By means of a parameterization, the threshold for undervoltage can be set to another value than the default value. For this, there is a specific selection parameter for US and UA which can be used to set the threshold to a value between 17.5 V and 20 V in increments of 0.5 V. This parameter is only available for "Device" but not for "Shared". The hysteresis to delete the alarm remains on 0.5 V. An improvement of the measuring accuracy of the existing circuit is not required. With the "old" GSDML (see PN certificate), the default threshold of the module is maintained.
