Monitor Component Temperatures
You can check the actual temperature of each heated component—the
reservoir and each hose and gun—using the automatic scan mode or by
manually selecting and checking each component.
By default, the melter remains in the automatic scan mode except when:
S The melter is placed into the setup mode
S The setpoint temperature of all hoses and guns i s set to zero degrees
S A fault occurs
To check component temperatures using the automatic scan mode
1. When the ready LED is on, observe the LEDs on the component keys.
2. When the LED on the key that represents the desired component
group (reservoir, hose, or gun) turns on, observe the left display until it
indicates the position number of the specific component you want to
check.
3. When the position number of the desired component appears in the
left display, observe the right display to determine the component's
actual temperature.
NOTE: On PURBlue 4 melters, 1 is the pump temperature and 2 is the
melt plate temperature when the reservoir LED is on.
