INTRODUCTION
Description
Operating modes
The B4 NS melter can be used in the operating modes described below:
Operating mode_ The melter keeps the hot components at the
temperature indicated on the display, which has been preselected
as the desired value. The pump-motor unit remains activated while
it waits for a consumption request via the opening of one or two
application guns.
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.
Warning: It is recommended that the equipment is disconnected from the
mains if it is not to be used for a long period of time. This prevents the PUR
