Melter equipment displays
Macro system series melters have two displays built into their control panel,
with three sets of 7 segments each for displaying the temperature values (set
point and real temperature), programmable parameters and alarms.
They are equipped with LED indicators to display the heating of each
component, as well as the pump activations and the main machine connection
signal.
They are also equipped with LEDs indicating equipment connection/
disconnection and standby function connection/disconnection:
LED display Component heating Component status
constantly lit constant low temperature
blinking slowly as need (according to PID parameters) temperature near set point
blinking rapidly programming or display change in set point values
