Transducer Power:
Two channels LVDT input, 230K Ohm input impedance.
9V/inch (0.35V/mm) - 1 Inch LVDT
10V/inch (0.39V/mm) - 2 Inch LVDT
3.5V/inch (0.14V/mm) - 4 Inch LVDT
Full scale meter range selected per Option Table.
• 0.33% of full scale error typical at +77•F (+25°C).
t 1% of full scale error maximum at +77°F (+25•C).
Alert/Danger alarm levels (adjustable from 0 to 100% of full scale).
Alarm delay times
are user-programmable per options.
LCD bar graph, dual scale with outside scales marked per monitor full scale range. Bargraph
resolution is 1.6% of full scale.
Green LEDs annunciate transducer OK condition and monitor mode, red LEDs annunciate
DANGER alarm, ALERT alarm, and BYPASS conditions.
Front panel switches (3) for reading ALERT and DANGER setpoint levels, and MODE for
changing between direct and differential modes.
Switches on circuit board for setpoint adjustment, Danger Bypass, Channel Bypass, and
Calibration functions.
External remote controls: Reset, Inhibit, and SetPoint and Calibration Adjust (t and i).
Output proportional to selected full scale monitor range and protected against continuous short
circuit to ground:
+4 mA to +20 mA, +12 Vdc compliance.
+1 Vdc to +5 Vdc, 100 Ohm output impedance.
0 Vdc to -10 Vdc, 100 Ohm output impedance.
-24 Vdc or -18 Vdc per option selected in power supply. Output is short circuit protected.
Alarms and OK: R e l a y drives for ALERT, DANGER, and system OK
