Transducer Power:
Alert/Danger alarm levels (adjustable from 0 to 100% of full scale).
Alarm delay times are user-programmable per options.
LCD bargraph, dual scale with outside scales marked per monitor full scale range. Bargraph
resolution is 1.6% of full scale. Center scale marked for probe Gap voltage.
Green LEDs annunciate transducer OK condition, red LEDs annunciate Danger, Alert, and
Bypass conditions.
Front panel switches (3) for reading Alert and Danger setpoint levels, and for reading probe
Gap voltage.
Switches on circuit board for setpoint adjustment, Danger Bypass, Monitor Bypass, and
calibration functions.
External remote controls: Reset, inhibit, and setpoint and calibration adjust (t and t).
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.
