MELTER OPERATION
3. Use the up-down arrow under the display to go past the selection for
the last day of the week (7).
The message ‘ON/OFF’ will appear on the display, depending on the
current status.
4. Press the button with the clock symbol once again.
The status will alternate each time you press the button.
5. Pressing either the up or the down arrow for element selection will exit
this program and return to the tank temperature display
Special function buttons
The simplicity of programming ‘B4’ series melters/applicators reduces the
use of the special function buttons to only the standby function.
This manual function allows you to alternate between the operational mode
and the standby mode. Using the standby function during periods of melter/
applicator 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/applicator 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 ‘B4’
melters/applicators 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.
