MELTER OPERATION MA-5052-ENG MACRO SERIES MELTER MANUAL
and the standby mode. Using the standby function during periods of melter
inactivity helps save energy and allows the heated elements to return quickly
to their set point temperatures once you return to the operational mode.
When the standby function is activated, the set point temperature for all
the heated components is lowered to a certain value, according to the
programmed parameter (see ‘Programming melter equipment parameters’).
For example, if the tank set point temperature is 160 °C and the standby
temperature is programmed as 30 (30%), when you press the standby function
button, the tank set point temperature will drop to 112 °C (70% of 160 °C).
The three means for activating the standby function available with Macro
melters have the following priority protocols:
1. Manual standby function button.
2. Standby function external signal.
3. Standby function activation/deactivation programming.
Therefore, if the function is activated by any of the three means, it may always
be deactivated using the manual button. On the other hand, if it was activated
using the manual button, it may not be deactivated by either of the other two
means. The weekly programming may not deactivate a standby function that
has been activated by either of other two means.
The following criteria are suggested for standby function use:
- If the period of inactivity is less than 2 hours, allow the melter
applicator equipment to heat as normal.
- If the period of inactivity is more than 2 hours and less than 4 hours,
use the standby function.
- If the period of inactivity is over 4 hours, use one of the following two
options: turn off the equipment if you do not plan on using it for the
rest of the day or keep the standby function on if you plan on using the
equipment during that same day.
Pumping control
Starting up the pump control card
The pump control card (hereingafter also control card), features an ON-OFF
button that allows us to turn off the displays and LEDs (leaving on only the 24
Vdc power supply LED)
The control card will turn off automatically depending on the status of
pumping permission input:
• Whenever the pumping permission input is deactivated, the interface
will be turned off and the control will be inoperative, unless turned on
with the control card ON-OFF button.
