Page 16: Switch Parameters ("List" Type)
User manual - METER SWE-N55L 7.2.2. Switch parameters (“LIST” type) Switch parameters can be described as a sets of values (a lists) out of which only one of the options available on the list can be selected for the given parameter. Options of switching parameter are selected using keys. - Page 17 User manual - METER SWE-N55L “SEt2” - second threshold of the relay (range -999 ÷ 9999). Negative values can be input by selecting a “-” sign on first digit ( to change value use [^] and [v] buttons). This threshold is accessible when “ modE” parameter is set to “in” or “out” value.
