Optical Protection Overview
The Sentinel Plus Press Brake Guarding System comes as standard with the LZS-005-R
Block Laser transmitter and receiver pair. The transmitter and receiver are mounted on the
upper beam of the press brake, allowing the operator to remain close to the work-piece as
the tools close at high speed. Hands and fingers are protected by a block of laser light that
monitors the zone around the punch. If an obstruction is detected the closing movement is
stopped. The punch cannot make contact with the obstruction.
The Sentinel Plus Press Brake Guarding System continuously monitors the critical speeds
and stopping distance of the moving member of the machine. If the safe speed is exceeded
and/or the stopping distance (overrun) is exceeded, the system will issue a stop command
to the machine. There is no need for a separate speed or stopping distance (overrun)
monitor.
Note:
The User Interface Panel displays the status of the machine, and any action
that is required by the operator. In the following sections the operator
messages are shown in the following format:
