INTRODUCTION
• Installation of hot-melt melters according to the security regulations
currently in force and the instructions provided in this manual (ancho-
ring, electrical connection, hydraulic connection, etc).
• Use of hot-melt melters in non-explosive, non-chemically aggressive
environments.
• Use of hot-melt melters following the safety instructions indicated in
this manual, as well as on the labels accompanying the equipment,
using adequate means of protection during each mode of operation.
Limited use
The Macro 200 hot-melt melters must be used for their intended uses and
never in the following conditions:
• Use with reactive polyurethane- or polyamide-based adhesives or any
other material that might cause safety or health risks when heated.
• Use of hot-melt melters in environments where cleaning is necessary
using water jets.
• Use of hot-melt melters to heat or melt food products.
• Use or operation without adequate safety protection.
Modes of operation
The Macro 200 hot-melt 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.
