Controls Interface
The Next key and Previous key allow the operator to scroll up and down
through the display items listed under the report menus. When the last item
of a report is displayed and the Next key is pressed, the display will wrap
around to the header of the report. When the first item of a report is
displayed and the Previous key is pressed, the display will wrap around to the
last item.
Select Settings Group
The first three keys on the second row – Operator Settings, Service Settings
and Service Tests – allow the operator to adjust various setpoints and perform
various tests. Certain items in these groups are password protected. Refer to
the Password section for additional information.
When a setpoint key is pressed, a header will be displayed. The setpoint
headers identify the available items and setpoint functions.
The Next and Previous keys function in the same manner as that described in
Selected Report Group, above.
Setpoint values are incremented by pressing the plus key and decre-
mented by pressing the Minus key. Once a setpoint is changed, the Enter
key must be pressed to save the new setpoint. If the Cancel key is pressed,
the setpoint value on the display will be ignored and the original setpoint will
remain.
