MELTER OPERATION
MA-5052-ENG
MACRO SERIES MELTER MANUAL
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’.
LED indicators
Described below are the LED indicators on the pump control card to identify
the status of the equipment:
1. Control card ON/OFF LED:
when the external 24 Vdc power supply is
present, this LED will always be illuminated; with no power supply, it will be
turned off. This LED is green in colour.
2. Pumping ON/OFF LED:
when pumping is enabled, this LED will be turned off,
and will be illuminated when pumping is disabled. This LED is in colour.
3. Int and ext (ok) LEDs:
when the equipment is operating in Internal start-stop
(ok) mode, the ‘int’ LED will be illuminated and the ‘ext’ LED will be turned off.
When the equipment is operating in external start-stop (ok) mode, the ‘ext’ LED
will be illuminated. And the ‘int’ LED will be turned off. These can never be both
on or both off at the same time. These LEDs are green in colour.
4. Int and ext (ref) LEDs:
when the equipment is operating in internal
reference mode, the ‘int‘ LED will be illuminated and the ‘ext’ LED turned off.
When the equipment is operating in external reference mode, the ‘ext’ LED
will be illuminated and the ‘int’ LED will be turned off. These can never be
both on or both off at the same time. These LEDs are green in colour.
5. Ext on LED:
when the equipment is operating in external start-stop
(OK) mode, and the external permission contact is closed, this LED will be
illuminated; if the external contact is open, this LED is turned off. This LED is
green in colour.
