MELTER OPERATION
Check the level of adhesive in the lower tank.
The tank of the machine’s roller applicator has a level sensor.
The sensor signal will manage the level of adhesive, providing a low level
signal.
The level sensor signal is established in the LOGO controller with a delay time
of 0.5 seconds.
For its electrical connection and selection of parameters, consult chapter ‘3.
Installation’ of this manual.
Activation/deactivation signal for the premelter grid.
The activation of the heating of the premelter grid has two operating modes:
1. Rotary switch (2) in AUTOMATIC. The grid will only be activated if the
level sensor of the roller tank does not detect adhesive. If a level is
detected, the grid will stop heating up.
2. Rotary switch (2) in MANUAL. The grid is always active.
Opening and closing of the adhesive discharge valve.
So that the discharge valve can open, the melter must be in Temperature OK
(both in automatic and manual mode). The activation of this valve has two
operating modes:
1. Rotary switch (2) in AUTOMATIC. The discharge valve will only open
if the level sensor of the roller does not detect adhesive. If a level is
detected, the discharge valve will close.
2. Rotary switch (2) in MANUAL. The discharge valve is always open.
Warnings and alarms.
1. Warnings:
They are shown on the LOGO controller screen, activate the screen’s
amber backlighting and the ‘reset’ button LED (and the tower light if it
is installed).
1.1. Lid open:
It occurs when the ‘closed lid’ sensor is deactivated and the piston is
stopped, except when the piston is up and the upper magnetic sensor
of the cylinder is activated. The warning disappears when the ‘closed
lid’ sensor is activated. Prevent any movement of the piston while the
warning is active.
