Indicators (Beacons):
Red LED’s annunciations:
•
A1: Lit when alarm 1 is in alarm state
•
A2: Lit when alarm 2 is in alarm state
•
A3: Lit when alarm 3 is in alarm state
•
REM: Lit when device is controlled by serial link
•
0-25-50-75-100-%: These six LEDs are always on to improve the bar graph
indication.
•
Kg/cm
2
, PSI, Bar, MPa: Engineering unit for the pressure input. These four
beacons are located within the display window, between the numeric digits and the
alarm beacons.
Green LED’s annunciations:
•
PEAK: Lit when lower display shows the peak value
•
TEMP: Lit when lower display shows the temperature input value
2.4 Primary Input
Primary Input:
Selectable between strain gage and linear by software configuration.
