MPW-1 is freely programmable device which by: light indicators on front panel, LCD display and set of relay outputs monitors the status of auxilliary voltage switchgear. For controlled voltage and current values the alarm threshold values of both types: up alarm or down alarm can be set. voltages and currents are presented in their primary values. The device controls also the position of each breaker by using isolated binary inputs. All the measured values and breakers statues are constantly sent to the supervision system. . There is also set of logical nodes to which any pair of contacts can be assigned. Example of assigned signals are: 400/230V AC switchgear: ATS blocked, ATS operation, unsuccesfull ATS, lack of voltage on TR1, lack of voltage on section 1, lack of voltage on TR1, lack of voltage on section 2 220 V DC switchgear: U<Un, U>Un, Battery AL1, Battery AL2, earthing module failure, earth fault, Rectifier 1 Alarm, Rectifier 2 Alarm 230V AC switchgear: U<Un, U>Un, Invertor operation on battery, Invertor Alarm 24 V DC switchgear: U<Un, U>Un, Rectifier 1 Alarm, Rectifier 2 Alarm All signals can be grouped as ALARM or Failure signals. 7 inch touch screen allows to monitor the operation of the auxilliary switchgears, preview of inputs and outputs, change the language, preview of real time, preview the event recorder data, preview the analog values.
