MELTER OPERATION
• 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.
To deactivate pump safety see the section ‘User configuration menu’,
paragraph 5.
Password security
If the option selected in the password security configuration is ‘1’, security
enabled, only the control card ON/OFF and pumping ON/OFF buttons will be
operational. While this security option is programmed, in order to avoid the
need to turn off and restart the machine to return to the ‘User configuration
menu’, on pressing any key (except the control card ON/OFF and pumping
ON/OFF buttons) a password will be required. When the password is entered
correctly, the control card can be left operational by setting it to ‘0’. When
using this method to access the control card security configuration options,
i.e., when the password has been entered, the buttons on the control card
are temporarily unprotected until one minute has elapsed during which no
buttons are pressed or until any key is pressed and the control panel resumes
its protected status.
Whenever you are requested to enter a security password, the message P00
will appear on the displays. With the up/down arrow keys, select the 3-digit
number that is your security password; as soon as the correct value for the
programmed password is selected, press the right arrow key, if the password
is correct, it will allow access to the selected field. The right arrow key will
validate the password, provided it is the correct one; if it not the correct
one, the message P00 will reappear on the screen and the process will
recommence.
By default, the password is set to ‘000’.
