2.
The pressure controller
DR 2
is found on the multi-functional block. It is set to a
jamming pressure of 1,5 - 2 bar, readable at its manometer.
The pressure preset results in the
minimum
strap tension, feed and sealing speeds.
Selection
directly
via consumer valves,
Y3
,
Y4
to
Y6
.
Main functions:
Precise movement pulse counting
Slow partial feed of strap
Slow return of strap during movement of head
“Head on packing item“

3.
The pressure controller
DR 3
is found on the multi-functional block. It is used to
set all speeds and strap tensions between minimum and maximum.
Selection via speed valve
Y1
on the multi-functional block and the relevant consumer
valve
Y6
.
The main function is the setting of the strap tension.
Pressure is set at the pressure control valve with valve
Y1
being activated and read on
its pressure gauge. The blow-off noise of the secondary ventilation can be heard on the
small pressure control valve
DR 2
, as long as
Y1
is selected. This is no problem.
The speed valve
Y1
can be activated in manual mode (emergency actuation) or
switched on via the control system.
Note!
Check the flow pressure at the tapping point. Flow pressure
exceeding 6 bar results in increased wear at the compressed air
motors. Pressure being too low results in reduced output.
