PUSH BUTTONS
7 user buttons are provided on the front to allow control and setting up of the system plus there is
an internal PCB button. These buttons are also numbered and shown in brackets e.g. button 3 is
(3).
Button 1 is the Accept/Mute and UP button. When in engineer’s mode, it is used to increment
parameters which are being modified. Also, it allows the displayed sensor to be moved onto the
next active sensor.
Button 2 is the “ - ” button. Used when decrementing items in engineer’s menu, also to escape from
the engineers menu system when not in any specific menu.
Button 3 is the SELECT button. It is used to enter and exit many of the engineer’s menus. Also
when first pressed, it prompts the entry of an engineer’s password. When correct, the engineer’s
menu is displayed in which sub-menus can be selected by pressing the
SELECT (3) button again.
Button 4 is the “ + ” button. Pressing this allows the display to hold the automatic sequence of
sensors being displayed for 999 seconds.
When in engineer’s mode, it is used to increment parameters which are being modified.
Button 5 is the DOWN button. Used when decrementing items in the engineer’s menu.
Button 6 is the DIM button. It is used for dimming the LED’s and LCD backlight and will toggle
between full brightness and the dim level previously set in the engineer’s menu. DIM can be used at
any time except when doing an LED test whereby automatic dimming occurs to reduce current.
Button 7 is the panel RESET and is used to clear faults or alarms. It is generally active and will act
regardless of entry of passwords.
Processor reset button and a flash programming jumper are situated directly on the PCB and
are not accessible from the front panel.
This button when pressed will restart the processor as if just powered up and should only be used in
the event of a system crash. The jumper removed for normal operation.
