Line Monitoring производства Siemens

Line Monitoring

Solid-state line monitoring relays provide maximum protection for mobile machines, plants and hoisting equipment or for unstable networks. Network and voltage faults can thus be detected early and rectified before far greater damage ensues.

The line monitoring relays with IO-Link monitor phase sequence, phase failure (with or without N conductor monitoring), phase asymmetry and undervoltage and/or overvoltage.

Phase asymmetry is evaluated as the difference between the greatest and the smallest phase voltage relative to the greatest phase voltage. Undervoltage or overvoltage exist if the set limit values for at least one phase are overshot or undershot. The rms value of the voltage is measured.

The relays are used above all for mobile equipment, e. g. air conditioning compressors, refrigerating containers, building site compressors and cranes.

Function

Application

Phase sequence

  • Direction of rotation of the drive

Phase failure

  • A fuse has tripped
  • Failure of the control supply voltage
  • Broken cable

Phase asymmetry

  • Overheating of the motor due to asymmetrical voltage
  • Detection of asymmetrically loaded networks

Undervoltage

  • Increased current at a motor with corresponding overheating
  • Unintentional resetting of a device
  • Network collapse, particularly with battery power

Overvoltage

  • Protection of a plant against destruction due to overvoltage

  • Can be used in any network from 160 to 630 V AC worldwide thanks to wide voltage range
  • Variably adjustable to overshoot, undershoot or range monitoring
  • Freely configurable delay times and RESET response
  • Width 22.5 mm
  • Display and transmission of actual value and network fault type to controller
  • All versions with removable terminals
  • All versions with screw or spring-type terminals
