DATA PAGE
This key when pressed enables the operator to select a page of MPC2000+ Displayable Data. For convenience the
data are grouped into logical pages. Each time the key titles as follows:
Measured Data
Calculated Data
Logical Inputs - Contacts Status
Statistical Data
Fault Data
Pressing the DATA PAGE key again after the Fault Data title has been displayed will result in the
display returning to the Measured Data title and so on.
LINE DOWN
After the desired Settings or Data page has been selected using the SET PAGE or DATA PAGE keys, pressing the
LINE DOWN key enables the operator to scroll forward or down the particular page. The display will move down
one item at a time unless the button is held for over half a second in which case the scroll speed will increase.
LINE UP
After the desired Settings or Data page to be viewed has been selected using the SET PAGE or DATA PAGE key ,
pressing the LINE BACK key enables the operator to scroll backwards or up the particular page of Settings or Data.
The display will move back one item at a time unless the button is held for over half a second in which case the scroll
speed will increase.
VALUE UP
After a particular setting parameter has been displayed using the above SET PAGE and LINE DOWN/LINE BACK
keys, pressing this key enable the operator to increase the value of the parameter displayed. The value will be
increased by one increment every time the key is pressed unless the key is held down for half a second in which case
the rate of change will increase.
The key will only increase the value of the parameter within the allowable range of the setting parameter.
If the Authorise input is open and the key is pressed the flash message ' Unauthorised Access' will be displayed and
the setting parameter will not be changed.
VALUE DOWN
After a particular setting parameter has been displayed using the above SET PAGE and LINE DOWN/LINE BACK
keys, pressing this key enables the operator to decrease the value of the parameter displayed. The value will be
decreased by one increment every time the key is pressed unless the key is held down for half a second in which case
the rate of change will increase.
The key will only decrease the value of the parameter within the allowable range of the setting parameter.
If the Authorise input is open and the key is pressed the flash message ' Unauthorised Access' will be displayed and
the setting parameter will not be changed.
STORE
This key is used to store a setting parameter to the non-volatile EEPROM memory after a change has been made using
the above mentioned keys. After the key has been pressed the flash message ' DATA SAVED OK' will be displayed.
If for any reason the change has not been correctly stored the message ' WRONG PARAMETER SAVED' will be
displayed.
If the STORE key is pressed whilst the display shows a Data parameter then the parameter currently being displayed
will be set as the default display which the MPC2000+ will always revert to if no key is pressed for 5 minutes and
provided a flash or constant message is not being displayed.
If the value of a parameter is changed but not stored and the display is scrolled to another page the parameter value
will be returned to the value stored in the EEPROM memory.
