Monitoring technique Phase monitor BD 9080 varimeter According to IEC 255, EN 60 255, VDE 0435 part 303 Monitoring of - Under- and overvoltage - Asymmetry - Phase failure - Phase sequence Release time adjustable between 0,1 ... 5 s One LED in each case for - Auxiliary voltage A1/A2 - Overvoltage U max. - Undervoltage U min. - Asymmetry / Phase sequence / Power failure - Contact position Closed circuit operation Available open circuit operation 2 changeover contacts Function diagram Width 45 mm Approvals and marking Applications For mounting three-phase networks for undervoltage, overvoltage, phase sequence, asymmetry, power failure. Indication 1. LED A1 / A2: on when operating voltage present 2. LED U : on in event of overvoltage max 3. LED U : on in event of undervoltage min 4. LED : on in event of: - asymmetry - incorrect phase sequence - power failure 5. LED: on when output relay activated Notes Measurement procedures: arithmetical mean value measurement over several half-waves of rectified phase voltages L1/L2 and L2/L3. Reference phase is L3. Networks with or without neutral can be monitored. The auxiliary voltage to be applied to A1/A2 can also be taken from the three- phase network which is to be monitored. This reduces to 0,8 - 1,1 U the H permitted range of voltage of the network to be monitored.
