6.5.2 Fault Current
The following table shows the current output in the event of a fault, depending on the characteristic.
6.5.3 Start Value and End Value
Please note when entering Start value and End value :
• Both values are to be entered in the units, which were selected under Units (section 6.2).
• Values between 0 mA and 20 mA can be entered, or between the values of these limits converted
into the selected units, using the parameters Zero point and Conversion factor see section 6.3.2
The difference between End value and Start value must be at least 1 % of the End value
(preset automatically by the device).
