1. 3 7 Switching output 0 The switching output channel is off DOSIx Switching output items 1 26 For 26 measuring energy 128 The switching output channel is on DOSxL Warning lower limit value 0 9999 Output warning when measured value is less than this value DOSxH Warning upper limit value 0 9999 Output warning when measured value is higher than this value Note 1 refer to table 15 for energy address 2 when warning lower limit is 0 lower limit warning will be invalid when warning upper limit is 9999 upper limit warning will be invalid Figure 2 Switching output settings All setting data of switching output is standardized to 2 bytes SX according to a formula The value is range from 1 to 1999 absolute value details of the formula as shown in figure 4 The meter has 10 units Schmitt sections when calculating alarm output For example if the measurement value is less than warning lower limit at first then it must be higher than warning upper limit with10 units in order to end warning Likewise the measurement value must be less than warning upper limit 10 units in order to stop warning So warning upper limit should be higher than warning lower limit with 20 units The maximal warning lower _ limit is 9979 and the least warning upper limit is 0020 For example for 10kV 100V meter set the first switching output corresponding with UA warning when UA lt 8kV or UA gt 12kV We know DOSI1 DOSI1 1 and PT PT 100 accordin2.
