Resetting Latched Indicators and Output Relays
All the indicators and output relays can be given a latching
function in the configuration.
There are several ways to reset latched indicators and relays:
•
From the alarm list, move back to the initial display by pushing
the CANCEL key for approx. 3 s. Then reset the latched
indicators and output relays by pushing the ENTER key.
•
Acknowledge each event in the alarm list one by one by pushing
the ENTER key equivalent times. Then, in the initial display,
reset the latched indicators and output relays by pushing the
ENTER key.
The latched indicators and relays can also be reset via a remote
communication bus or via a digital input configured for that
purpose.
Adjusting Display Contrast
The readability of the LCD varies with the brightness and the
temperature of the environment. The contrast of the display can
be adjusted via the PC user interface, and SetPointPS software.
Local Panel Operations The front panel can be used to control objects, change the local/
remote status, read the measured values, set parameters, and to
configure relay functions. Some parameters, however, can only be
set by means of a PC connected to one of the local communication
ports. Some parameters are factory-set.
Navigating in Menus
All the menu functions are based on the main menu/submenu structure:
1.
Use the arrow keys UP and DOWN to move up and down in the
main menu.
2.
To move to a submenu, repeatedly push the RIGHT key until the
required submenu is shown. Correspondingly, push the LEFT
key to return to the main menu.
3.
Push the ENTER key to confirm the selected submenu. If there
are more than six items in the selected submenu, a black line
appears to the right side of the display (Figure 2.6). It is then
possible to scroll down in the submenu.
4.
Push the CANCEL key to cancel a selection.
