Temperature adjustment
“AL” is calculated by the PLC, which automatically subtracts 10°C from every value set for SP1.
Example: Operating temperature SP1 = 200°C, therefore AL = 190°C.
IMPORTANT NOTE: The set point for operation (SP1) must be set according to the characteristics
of the glue used.
Otherwise, there is the risk of breakage to the mechanical and/or electrical components of the glue
spreading roller.
We suggest starting with edging operations 5 minutes after the glue pot has reached the required
temperature of 200°C.
When temperature SP1 has been reached and with the feed chain halted, after 10 minutes the ma-
chine moves into STANDBY, and the PLC adjusts the temperature to SP2.
