MA-5052-ENG MACRO SERIES MELTER MANUAL
The value displayed corresponds to the increase in real temperature
over the set point temperature permitted without activating the alarm
message.
4. Use the right arrow to advance to the next screen.
5. Exit the special menu using the left arrow and the tank temperatures
will once again be displayed.
All the special menu values will be saved.
Keeping a component on display
By default, the main display shows the tank temperatures. However, it is
possible to display indefinitely the temperatures of any component for analysis
or tracking.
1. Select the component you wish to see permanently with the left-right
arrow.
The corresponding LED will blink rapidly.
2. Hold the arrow button down for two seconds, selecting the desired
component.
3. The display will now remain on the selected component, without
changing.
4. Simple press any left-right arrow button again to restore the default
display (tank).
External I/O connections
The melter’s input and output signals (I/O) allow it to communicate with the
main machine simply and directly.
There are seven signals that may be used to communicate with the main
machine:
• Temperatures ok_an output from a non-voltage contact that
communicated to the main machine (or to a warning light beacon) that
all the system temperatures have reached 3° below their set point
value (and the delay time have finished) during start-up, or that their
real value is not 20°C below their set point value during operation.
• External Standby_control input from the standby mode, via a non-
voltage contact. The standby function is connected with a closed
contact; an open contact disconnects it.
• Low level_an output from a non-voltage contact that communicates to
the main machine (or to a warning light beacon) that the adhesive fluid
level in the tank has reached the minimum level established (optional)
