Dalton -
process lock
Dalton – the intelligent process lock
Dalton is a locking unit that is intended for use in preventing
unnecessary process stoppages, i.e. it is not a safety lock. It can
be used either as a free-standing lock or integrated with Eden as
a safety sensor. In the unlocked state the door is held closed by a
ball catch and
in locked state the balls are mechanically blocked
so the lock tongue can not be pulled out
. If necessary, the holding
force of the ball catch can be adjusted. The device only allows to
lock when the ball latch is centred around the lock tongue, and
when Eva is with Adam (depending on version). When an input is
supplied with voltage, the ball catch is locked.
Dalton is easily connected with an M12 connector. The Tina
junction block can be used for distribution of both the safety and
locking functions. The Dalton status is indicated by LEDs and can
also be read by a PLC via the information output.
Dalton has a modular structure
The Dalton process lock has a modular structure and can
be combined in different ways depending on position,
installation and function. You choose the lock housing, lock
tongue and fixing plate yourself to create a complete Dalton.
Installation
Dalton offers many different installation possibilities as the lock
tongue may enter the ball catch from three directions
. In order
to ensure that Dalton works without any problems, the ball
catch
must be resting, i.e.
the balls
not pressed in by the lock tongue
when the door is
in
closed
position.
Dalton's brackets are therefore
made to ensure
easy adjustment of
the lock tongue and ball latch
positions.
Dalton is easy to install, adjust and
dismantle in the Quick-Guard fence
system's T-slots.
