USP ALPHA-H Operating Instructions Manual

Description
Unique Safety Products ALPHA is an Interlock Blocking
device designed to provide additional safeguarding to
prevent operators being trapped inside a safeguarded
space in machine guarding applications where whole body
access is required. The ALPHA works in conjunction with
existing interlocking to prevent the unexpected reset or
restart of the safety-related circuit. It works by forcing the
removal of a personnel or safety key before the guard can
be fully opened and preventing the guard from fully closing
until the key is returned. Thus, while the key is with the
operator inside the area, the interlock is blocked from
allowing the machine to be reset or restarted. Additional
padlock points allow for each individual entering the area to
apply their own means of control to the device.
As a purely mechanical component complete with an
integrated mounting plate it is easily retrofitted or added to
an existing system, regardless of interlock type, without the
need for wiring or programming.
