MELTER OPERATION
• Should the 24 Vdc power supply to the control card be lost, on
recovering the power supply the control card will remain turned off
until pumping permission input is activated. If on recovering the
power supply the pumping permission input is activated, it will turn on
directly.
• If the power supply is available and pumping permission has not been
received and the control card be turned off it must be turned on with
the control card ON-OFF button.
Pumping safety measures
To prevent the equipment from starting up unexpectedly, the control panel
features by default a safety option that prevents pumping from commencing
until enabled by pressing the ON-OFF button on the control card. This function
may be disabled in the ‘User configuration menu’.
For the pumping control to allow the pump to operate, the pumping ON-OFF
button must be pressed, leaving it enabled (the red LED on the pumping ON-OFF
button will turn off). When enabled, the control card will allow pumping as soon as
all the required conditions are recovered, including pumping permission.
When pumping safety is enabled:
• In the event of loss of 24 Vdc power supply or the control panel is turned
off with the control card ON-OFF button, the control will start up with
pumping disabled (red ON-OFF button LED is illuminated) on recovering
the power supply or turning the control card on, and prevent pump
operation even if the pumping permission input is closed again, until the
pumping ON-OFF button is pressed and the red LED turns off.
• Whenever the pumping permission input is deactivated, the control
disables pumping (red ON-OFF button LED is illuminated) and prevents
the operation of the pump even if the pumping permission input is
closed again, until the pumping ON-OFF button is pressed and the red
LED turns off.
• Whenever an error occurs, the control disables pumping (red ON-OFF
button LED is illuminated) and prevents the operation of the pump until
the error is reset, the pumping ON-OFF button is pressed again and the
red LED turns off.
When pumping safety is disabled:
• In the event of loss of 24 Vdc power supply or the control is turned off
with the control card ON-OFF button, on recovering the power supply or
turning on the control card the control maintains the enabled status of the
pumping ON-OFF button (if this was at the position ON, the unit will start
up in ON and if it was at the position OFF it will start up in OFF).
• Whenever pumping permission input is deactivated, the pumping
control stops the pumping operation, but does not disable it (red ON-
OFF button LED turned off) and will allow pumping operation as soon
as the pumping permission input is closed again.
• Whenever an error occurs, the pumping control stops the pumping
operation, but does not disable it (red ON-OFF button LED turned off)
and will allow pumping operation.
