Azbil Corporation No. SS2-MTG300-0300 - 3 - Lightning protection 12 kV, 1000 A Equipped with the lightning arrester in the power source and external output terminals. Power failure An EEPROM retains data record of totalized value when pulse output is used (retention period approximately 10 years). Power supply 15.6 to 42 V DC (without communication) 21.05 to 42 V DC (with communication) Current capacity: 24mA min Size Wafer style 25, 40, 50, 65, 80, 100 mm (1, 1., 2, 2., 3, 4 inches) Flange style 2.5, 5, 10, 15, 25, 40, 50, 65, 80, 100, 150, 200 mm (0.1, 0.2, 3/8, 1/2, 1, 1., 2, 2., 3, 4, 6, 8 inches) Flange rating ANSI150, ANSI300, DIN PN10, DIN PN16, DIN PN25, JIS10K, JIS20K, JIS30K Reference flange standard JIS; JIS B2210 (1984) ANSI; ANSI B16.5 (1988) Ambient temperature limits -20 to 60°C (-4 to 140°F) Ambient humidity limits 10 to 90% RH Vibration effect Integral style: 4.9m/s2(0.5G) max. “Electrode status output mode” table” Output/Display Parameter selection in the “Electrode status output mode” OFF ZERO HOLD Analog 4-20mA output Output values as the meter measures. Analog output is fixed to 0% (4mA). Analog output is held at its last good value. Pulse output Output values as the meter measures. Pulse output is fixed to 0 (does not generate pulses). Pulse output is held at its present state. Display Display the value as it measures. Flashes the message 0% and “Empty or scale on electrode” alternately (when % flow rate is specified for the main display). Flashes the message 0.000 RATE and “Empty or scale on electrode” alternately (when actual flow rate is specified for the main display). Flashes the message XXXXXXXX (totalized value at setup) and "Empty or scale on electrode" alternately (when totalized value is specified for the main display). Flashes the values at its last good values and a message of “Empty or scale on electrode” alternately. Electrode status diagnostic Detect empty pipe condition or scale on electrode by monitoring flow rate signal. Once the flow rate signal fluctuates over a certain threshold, the device judges that the detector is empty or scale on electrode. The Electrode status diagnostic function makes the analog output and pulse output to the values as selected in the below “Electrode status output mode” table. The display alternately shows the output values selected and “EMPTY OR SCALE ON ELECTRODE”. There are five threshold levels to meet an environment where the device is installed. Set an appropriate threshold level from below. SENSITIVITY HIGH SENSITIVITY MID SENSITIVITY LOW SENSITIVITY LL SENSITIVITY LLL Default setting: OFF Operating condition: The following conditions must be met when using the electrode status diagnostic function. . Diameter: 10mm or larger . Electric conductivity of fluid: 30 ..S/cm or greater . Grounding: Grounding resistance must be less than 100.. . The noise level must be over the set threshold when the pipe is empty. . The noise level must be under the set threshold when the process fluid flows in the detector. 4 12
