Special function buttons
The simple programming of the B4 VS melters means that the special function
buttons are only used for the standby function.
This manual function allows you to alternate between operating mode and
standby mode. Using the standby function during periods of melter inactivity
helps save energy and allows the heated components to return quickly to their
set point temperature when you return to operating mode.
When the standby function is activated, the set point temperature for all
the heated components drops to a certain value based on the programmed
parameter (see ‘Programming the melter parameters’). For example, if
the tank set point temperature is 160°C and the standby function is set to
30 (30%), when the standby function button is pressed, the tank set point
temperature will drop to 112°C (70% of 160°C).
The three systems for activating the standby function in the B4 VS melters
have the following priority protocols:
1° Manual standby function button.
2° Standby function external signal.
3° Standby function activation/deactivation program.
Therefore, if the function is activated using any of the three systems, it can
always be deactivated using the manual button. However, if the function is
activated using the manual button it cannot be deactivated by either of the
other two systems. The weekly programming cannot deactivate the function if
it has been activated via any of the other two systems.
The following criteria is suggested for using the standby function:
- If the period of inactivity is less than 1 hour, leave the melter to heat as
normal.
- If the period of inactivity is more than 1 hour but less than 2 hours, use
the standby function.
- If the period of inactivity is more than 2 hours, turn off the equipment.
