Ground Monitors
3M Ground Master Equipment Ground Monitors are designed to provide
continuous monitoring of proper ground connections of up to eight tools
and up to 16 tools in tandem with another Ground Master monitor. The
monitor shows which individual ground connection is being monitored
and its status. Ground Master also monitors EMI on each ground, to
assist in diagnostics of lockups and malfunctions.
Each ground connection has its own easily replaceable fuse to prevent
dangerous voltages from incorrect wiring propagating to other equipment.
Ground Master provides intelligent information to a facility monitoring
system with detailed status on each ground connection. 3M Ground
Master RT provides relay closure and a logic signal to the tool so that
it can be shut down in case of ground failure. Contact 3M for the best
model for your applications.
