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 1-
7. Only trained service engineers should be authorized with a
password. Refer to the Commissioning Manual for details.
In any case FUNCTION, MAINTENANCE and SETUP options can be
read but is not possible to change them without 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 (see
Communication Handbook).
The Alarm and Warning messages are detailed in Chapter 6
