The FUNCTION, MAINTENANCE and SETUP options all require a password, which is set by the commissioning
engineer. This manual does not provide servicing instructions and the options accessed from these windows are
therefore not shown on the menu map in figure 8-4. Only trained service engineers should be authorized with a
password.
In any case FUNCTION, MAINTENANCE and SETUP options can be read but it is not possible to change them
without the password.
• Option Selection Mode
If a window from which options can be selected is displayed, a pair of indicator arrows appear at the extremities of the
line.
The UP/DOWN push buttons move these up and down the screen over the options. When the arrows point at a chosen
option, press ENTER to display the next window. Press ESCAPE to return the previous window to the screen.
Alarm/Warning messages
The Alarm and Warning messages are shown on the three upper lines of the display. The ALARM indicator (red) and
audible warning accompany all Alarm messages.
There is a default selection for every message and corresponding mode of red indicator ( OFF, ON, FLASHING ) and
buzzer sound ( OFF, ON, INTERMITTENT, SINGLE SOUND ).
The default mode can be changed according to particular needs of the plant, a PC and communication program are
needed .
The Alarm and Warning messages are detailed in Chapter 10 - Display Panel Interpretation of this manual.
