MA-5195-ESP PS20 NON STOP+ DRUM UNLOADER MANUAL
Activate the air supply to pass and turn the pressure regulator clockwise.
The ratio between the pneumatic pressure and the hydraulic pressure on the
circuit is 1 to 13 bar.
Warning: A 6 bar on the grid, the maximum pressure on the hydraulic circuit
reaches 80 bar. There is a risk of burns or particle projection. Use thermal
protective gear and goggles.
Hose and applicator connection
PS20 NS+ melters use standard Meler components. The entire range of Meler
hoses and applicators may be connected to this equipment.
Up to four hose-applicator outputs may be connected to PS20 NS+ system
melters, depending on the number of pumps installed.
Warning: When connecting hose-applicator outputs, verify that the connected
power is not above the maximum allowable power for each output.
The PS20 NS+ melting equipment is equipped with a hydraulic distributor for
each pump, with 2 possible outputs, depending on the connections that will
be used. Connect the hoses to the distributor according to the needs of the
installation and the ease of connection.
Caution:
• In order to identify each hose-applicator, electrically connect them to
the connector with the same number as the output they use.
• It is preferable to use couplings at a 45° or 90° angle to minimize the
space the hoses occupy. Using straight couplings usually results in
curves with very small radii that may damage the inside of the hose.
• Save the screw-on caps that are removed from the distributor in order
to connect a hose. They may be necessary in the future if a hose is
removed from its location.
• Perform the electrical hose and applicator connections with the equi-
pment turned off. Failing to do so may result in electrical defects in
theconnection and the appearance of alarm messages on the melter
display.
Parameter Programming
Once the melter/applicator and its components are installed, you will need to
program the operational parameters appropriate for the specific application
that will be performed.
Among the various parameters, it is necessary to program the set point
temperature values for each component connected and the value for
overheating warnings. There are two other parameters (weekly start-up and
shut-down programming and the standby temperature value) left to program
in advanced systems, although the factory default values are perfectly valid for
operational purposes.
Chapter “4. MELTER OPERATION” details the operating modes of the machine
and its configuration.
