Description
Recirculation hose
(recirculation connection)
25
D
1
: Tank 1 is equipped with a recirculation
connection (max. 4 hoses).
2
: Tank 2 is equipped with a recirculation
connection (max. 4 hoses).
3
: Tank 1 and 2 are each equipped with a
recirculation connection (max. 8 hoses).
Flow control
26
−
T
: This function allows the speed to be regulated to
an adjustable value as soon as the parent machine
stops.
B
: This function allows the material pressure to be
reduced through the pneumatic pressure control
valve when the motor stops.
Pressure build-up
26
−
N
: The mechanical safety valve with Reed switch
replaces the installed mechanical safety valve. One
pressure sensor per pump stream. Double-stream
pumps are equipped with two pressure sensors:
one for display and one for control. There is no
pressure control valve.
This feature allows the material pressure to be
regulated to an adjustable value as soon as the
parent machine stops or when the line speed signal
falls below an adjustable value.
Safety valve with display
26
−
O
: The mechanical safety valve with Reed switch
replaces the installed mechanical safety valve.
There is no pressure control valve.
If filters or application nozzles are blocked, the
material pressure increases. The safety valve
opens at 85 bar, and the material flows back into
the tank.
The Reed switch on the safety valve generates an
electrical signal that can be emitted as a fault or a
warning.
Pressure display
27
−
A
: One pressure sensor per pump stream after the
filter (double-stream pumps are equipped with two
pressure sensors).
G
: One pressure sensor per pump stream before
the filter (double-stream pumps are equipped with
two pressure sensors).
H
: One pressure sensor each per pump stream
before and after
the filter (double-stream pumps
are equipped with two pressure sensors).
The melter outlet pressure is displayed and
monitored. Alarms for underpressure and
overpressure are displayed.
