4.2.3 - STARTING UNIT AND SELECTING AN OPERATING
TYPE
The unit can be started in local mode, or unit operating
type can be changed at any time using the Start/Stop
button. In the example that follows, the unit is stopped
(LOFF) and the user wants to start the unit in local mode.
4.3 - MENUS
4.3.1 - SELECTING A MENU
The MENU button authorises you to select a menu from
the 10 main menus that are available. Each time you
press this button one of the 10 LEDs lights up in turn
alongside each of the icons representing a main menu.
The active menu is the one against which the LED is lit. If
a menu is empty then its LED is not lit. To scroll quickly
through the menus, hold the MENU button down.
4.3.2 - SELECTING A MENU ITEM
The up and down Arrow buttons let you scroll through
the menu items. Menu item numbers are displayed in
the two-digit display. The item number increases or
decreases every time you press the up or down Arrow
button. The menu items that are not in use or
incompatible with the configuration are not displayed.
The value or status associated with the active item is
displayed in the four-digit display. To scroll quickly
through the items, hold the up or down Arrow button
down.
4.3.3 - MODIFYING THE VALUE OF A PARAMETER/
ACCESS TO A SUBMENU
Press the Enter button for more than 2 seconds to enter
the modification mode or to select a sub-menu. This lets
you correct the value of an item or select a sub-menu
with the aid of the up and down Arrow buttons (if you are
authorised to overwrite the item concerned). When
modification mode is activated, the LED for the main
menu to which the item belongs as well as the 2-digit
display flash in the menu block. Once the required value
is obtained, press the Enter button again to validate the
change or to access the sub-menu. The LED for the menu
to which the item and the 2-digit display belong then
stops flashing, indicating that modification mode no
longer applies.
In modification mode, the value to be modified increases
or decreases in steps of 0.1 every time you press the
Arrow buttons. Holding one of these buttons down
increases the rate of increase or decrease.
NOTE: The access to a sub-menu may require entering a
password. This is automatically requested. See section
4.3.11.2.
The following example shows how to modify the value of
item 1 in the Setpoint menu.
4.3.4 - EXPAND DISPLAY
Pressing the Enter button causes a 23 character text
expansion to be scrolled across the four-digit display.
All user menus provide an expansion of the current
displayed parameters. If the expansion is complete the
four-digit display reverts to item value. This function can
be inhibited through the User Configuration menu.
