MA-5068-ENG MACRO 200 INSTRUCTIONS MANUAL
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)
• Output disabled_ disabled input signal for each hose-applicator output
via a non-voltage contact. With a closed contact, the output remains
activated (output on); with an open contact, it is deactivated (output off).
• Motor start up_ for each pump installed, the motor start up may be
controlled by closing an external non-voltage contact.
• Motor speed set point_ for each pump installed, the rotational speed of
the motor (and therefore, the pump) may be controlled by means of a 0
to 10V DC external signal.
• Failures output in pump control card_ output from a non-voltage
contact that communicates normally to a warning light beacon the
failure from the pump control card.
