Workstation monitor WS Aware

dpvlink 14088

WS Aware workstation monitor allows the permanent monitoring of two workstations. The measuring device equipped with a DSP (digital signal processor) monitors the flawless ground connection of users, tools and working surfaces. Furthermore, EMI events are registered and displayed. WS Aware monitors detect all grounding parameters of the working environment in accordance with the requirements of ANSI 6.1 and ANSI/ESDA S. 20. 20.

The WS Aware workplace monitor is available in two versions: with 2x Remote Terminal Standard CTA242 or with 2x Big Brother Remote Terminal CTA243

  • Permanent monitoring and logging of all detected events via a current data output by a Facility Monitoring System (FMS) or optionally via a digital MODBUS interface, for networking via Ethernet network
  • Monitoring of the impedance of two low-impedance (e.g. for tools, soldering irons, machines) and two high-impedance (e.g. table mats) grounding connections
  • Monitoring of EMI voltages occurring at the low-impedance grounding connections
  • Adjustable alarm limit values
  • visual indication of exceeding the set limit values by LEDs (OK green, alarm red, EMI voltage flashing yellow)
  • Additional acoustic alarm function (can be switched off)
  • Deactivation of unused inputs via DIP switch (corresponding indication by dark LED)
  • Two remote terminals for monitoring two double-wire wrist straps each (operator and visitor)
  • Permanent measurement of leakage resistance and body voltage
  • Terminals with Big Brother function: detection of a person at the workstation using a photo sensor and alarm triggering via the remote terminal in the absence of grounding

Properties:

  • "Big Brother" monitoring function detects users who are not correctly grounded
  • Extremely low voltage (25mV CA) for permanent monitoring of voltage and resistance of the twin conductor wrist straps 
  • Monitoring of grounding parameters according to ANSI 6.1 and ANSI/ESD S20.20
  • EMI monitoring of ground connections
  • RJ45 port for data transfer to the computer
