Application:
Two-Hand Control Monitoring
The stamping machine shown in this application presents a hazard to
the operator should he come in contact with the moving parts during
operation. A safeguarding solution must be put in place that guarantees
the operator will remain a safe distance away from the machine while it
is in use.
Description
A two-hand control safeguarding system will prevent the
operator from approaching the machine while a hazard is present. The
machine cycle will begin only when the operator touches both
Self-Checking Touch Buttons (STBs) within half a second of each other
and will continue operation only as long as both hand controls are
actuated, thereby assuring that the operator will remain at the control
station while the machine is in use.
The diverse-redundant, self-checking design of the STBs will detect an
internal safety-critical circuit fault and prevent machine operation.
The AT-FM-10K self-checking two-hand control module provides further
assurance of machine safety. Combining the Self-Checking Touch Buttons
with a two-hand control module achieves maximum safety level EN 574
(type IIIC) two-hand control system.
NOTE: This safety solution only protects the machine operator. Other
safety devices need to be in place to protect other workers in the area.
Ergonomic and robust solution for two-hand control actuation and
safeguarding when interfaced with DUO-TOUCH SG Two-Hand Control Modules.
Accessories include floor and free-mounting stand, EZ-LIGHT indicators
and optional mounting brackets.
