MELTER OPERATION
4-13
MA-5168-ENG
ADHESIVE MELTER CANTHO
1.2. Block finished or chamber without adhesive:
It occurs when the piston arrives at the lowest position (the lower
magnetic sensor is activated). This warning stops the pushing
movement of the piston and prevents it from pushing until the warning
disappears. The warning disappears when the rotary switch (1) for
moving the piston is placed in the ‘up’ position and the piston goes up
until the upper magnetic sensor is activated.
The finished block can also be detected visually through the dent of the
rod that is built into the piston. When this reaches the lid level, the
block is finished. This visualisation is just indicative and you should
wait for the warning signal before loading a new block.
1.3. Cylinder position fault:
This occurs when the pneumatic cylinder’s magnetic sensors are active
at the same time. The warning disappears when at least one of the
magnetic sensors is deactivated. Prevent any movement of the piston
while the warning is active.
1.4. Piston does not go up:
It is shown if the piston switch is in the ‘up’ position and the upper
magnetic sensor is not activated in 30 seconds. The warning will
disconnect the cylinder electrovalve. The warning disappears when
the upper magnetic sensor is activated. To raise the piston (with the
warning still activated), the piston switch (1) must be returned to ‘0’
and turned to the ‘up’ position.
2. Alarms:
They are shown on the LOGO controller screen, it activates the red
backlighting of the screen and it also activates the intermittent LED of
the ‘reset’ button (and the tower light if it is installed).
2.1. Lid open:
This occurs when the ‘closed lid’ sensor is deactivated and the piston is in
movement. This alarm stops the piston movement. It is reset when the
‘closed lid’ sensor is activated, pressing ‘reset’. By resetting the alarm,
the piston will move according to the status of the switch (1).
2.2. Block finished or chamber without adhesive:
If the warning for ‘block finished or chamber without adhesive’ is active
for a longer time than the time programmed between 0 and 60 minutes
(T. ALARM on the main controller (LOGO) screen, the alarm will be
produced). This alarm is reset by raising the piston to the upper
position (placing the piston movement switch (1) in ‘up’ position and
when the upper magnetic sensor is activated, pressing ‘reset’.
2.3. Machine disconnected:
This occurs when the Cantho melter is disconnected from the electrical
control panel. The alarm deactivates all of the LOGO controller outputs.
To reset the alarm, reconnect the machine to the electrical panel and
press ‘reset’. From that moment, the machine will act according to how
the rotary control switches are positioned and the status of the roller
tank level sensor.
