Interlock System - DAINIPPON SCREEN PLATE RITE 4300 User Manual

6. Interlock System

The PT-R is equipped with an interlock system to protect the operator. When any of
the doors is opened, the interlock switch placed at the door activates and cuts off the
laser light.
With the exception of times when maintenance personnel are
performing maintenance procedures, do not disengage the
interlocks. Operating the PT-R with the interlocks disengaged may
result in serious personal injury.
If any of the doors are opened during exposure, the interlocks will
activate and automatically stop the rotation of the rollers, main
drum, and feed section, as well as the movement of the transfer
unit. However, approximately 4 seconds is required for the main
drum to come to a complete stop. Do not under any circumstance
touch the main drum until it has come to a complete stop.
