MA-5066-ENG PS200 DRUM MELTER MANUAL
Limited use
PS200 drum melters must be used in the manner in which they are intended,
and never under the following conditions:
• Used with materials that may represent safety or health hazards when
heated.
• Use of melting equipment in environments which must be cleaned with
water jets.
• Use of melting equipment to heat or melt food products.
• Use or handling of melting equipment without adequate safety
protection.
Modes of operation
These melters may be used in all of the following modes:
Work mode_ The hot-melt melter keeps materials hot at the pre-
selected temperature indicated on the display. The pump is kept
activated, waiting for the consumption command when one or more
applicators are activated.
Internal control of pumping and speed _ Switches in the position
ok ‘int’ and ref ’int’. In this mode of operation, the user has full
control of pumping and the set speed of the pump rotation.
Control of internal pumping and external speed_ Switches in the
position ok ‘int’ and ref ’ext’. This mode of operation is performed
through internal pumping control and speed control by means of
an external 0-10 V signal sent from the main machine.
Control of external pumping and internal speed_ Switches
in the position ok ‘ext’ and ref ’int’. This mode of operation is
performed through external pumping control and manual speed
control.
Control of external pumping and speed_ Switches in the position
ok ‘ext’ and ref ’ext’. In this working mode, both pumping and
speed are controlled from the main machine. Speed is controlled
by means of an external 0-10 V signal sent from the main
machine.
Standby mode_ The hot-melt melter remains in a resting state, with
the materials kept at (programmable) temperature values below the
pre-selected value. The pump remains deactivated.
Alarm mode_ The hot-melt melter detects a malfunction and warns
the operator of this event. The pump remains deactivated.
Stop mode_ The hot-melt melter remains off, without heating the
materials and with the pump deactivated. The electrical and pneumatic
supply remains activated between the network and the system,
however.
