Safe Amplifier/PullSwitch Stations
The amplifier/pullswitch
stations consist of:
• Amplifier
module will give a pre-start warning and allow full speech
functionality along
the conveyor and to the surface.
• Remote isolation lockable switch. The isolation
can be confirmed via a voice message
repeatable by interrogation button or optional
visual indication.
• The amplifier can incorporate an interrogate button
to reinitiate the “stop messages” if
the conveyor has stopped. The pullswitch also
has reflective ‘eyes’ when in a lockout
position as a further indication of a locked out
belt.
• The amplifier/pullswitch station is usually positioned
along the conveyor walkside only
and alternated with pullswitch stations.
• A remote amplifier/pullswitch station telephone
keypad is available. This unit can be
positioned at the drivehead or at a strategic
position along the conveyor. A single pair
would then be taken from this unit, connected
into a surface “TARA” unit, and linked into
your PABX as a separate extension. This allows
direct telephone link onto your
conveyor.
