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.
Strain Gage Input: From 340 to 5000K, 1-4mV/V. Excitation 10V ±7%. 5 wire
connection.
Input Signal: -25/125% of full scale (approximately –10 / 50mV).
Shunt Calibration: With or without shunt resistor (value programmable from 40.0 to
100.0%).
Zero Balance: ±25% of full scale (approximately ± 10mV).
Linear Input: Selectable between 0-5Vdc, 0-10Vdc, 0-20mA, 4-20mA.
Auxiliary Power supply: 24Vdc / 1.5W ± 2% power supply for two or four wire
transmitter.
Input Impedance:
<10K for linear current input
>165KK for linear voltage input
Input Protection: Open circuit detection for strain gage (on signal and excitation wires)
and 4-20mA inputs; it is not available for 0-5Vdc, 0-10Vdc and 0-20mA. Up or down scale
keyboard programmable.
Sampling Time: 50mS typical.
Display Update Time: Selectable: 50, 100, 250 or 400mS.
