Ground Master® Monitor
dpvlink 16954

Know whether your equipment is properly grounded at all times

Proper grounding is crucial for safe and uninterrupted operation of equipment. In critical environments broken ground connection may result in personnel exposure to dangerous voltage, equipment lockup or malfunction and damage to sensitive components.

Ground Master offers continuous monitoring of proper ground connection of up to 8 tools (and up to 16 tools in tandem with another Ground Master). Status indication, Ground Master shows which ground connection is being monitored,which one is OK and which one has failed. Enabling switches for each ground connection allow for accurate and safe indication. With safety in mind, every ground connection has individual easily-replaceable fuse to prevent dangerous voltages from miswiring propagating to other equipment.

In addition to ground connection, Ground Master offers monitoring of EMI on each ground, assisting in diagnostics of lockups and malfunction.

Ground Master provides intelligent information to a facility monitoring system with detailed status on each ground connection. Ground Master RT provides relay closure and logic signal to the tool so that it can be shut down in case of ground failure.

Application example: monitoring of assembly tool
Many assembly tools consist of several parts which are not always grounded. Their ground connection may also be broken during maintenance, modifications and even in normal use. Ground Master® can monitor ground connection of every single part of the entire tool to assure its compliance with the standards and uninterrupted operation of the tool. Ground Master® RT can provide relay closure or logic level signal to the tool to stop in case of ground failure.

Ordering information
Ground Master comes with:

  • four spare fuses
  • grounding hardware
  • universal power adapter
  • user manual

Key advantages

  • ANSI/ESDA S.20.20 compliant
    Ground Master measures ground impedance in accordance with requirements of ANSI/ESDA S.20.20 standard
  • Adjustable alarm threshold
    The alarm threshold can be easily adjusted at any time in a range of 1 to 20 Ohms
  • Safety
    Each ground connection is protected by individual fuses to protect equipment in case of miswiring of neutral, power and ground
  • EMI
    Ground Master monitors EMI on each ground and indicates EMI status
  • Output to Data Aquisition or Facility Monitoring System
    Ground Master monitors provide intelligent output to a data acquisition or facility monitoring system. Power can be supplied via the same cable from FMS as well
  • Output to the Tool
    Ground Master RT provides relay closure and logic signal to the tool to shut it down when any of the grounds fail
