  • Page 21 47DV ■ FUNCTIONS, TERMINOLOGY • Alarm action basics Alarm trip operates in relation to the display value. Alarm indicators, except for P indicator, do not turn on until all parameters (display value, deadband, ON delay time elapsed) of the setpoint become true. Display color is switched accordingly.
  • Page 22 47DV • Dedband (Hysteresis) Once a high trip alarm is ON, the alarm stays ON until the data becomes lower than the deadband value from the setpoint. Once a low trip alarm is ON, the alarm stays ON until the data becomes higher than the deadband value from the setpoint.

  • Page 29 47DV • Low-end cutout Input signal below the preset cutout value is forcibly cut to 0. Typically used to avoid negative reading. Set for the three low- est digits of the scaled range (disregarding the decimal point). • Automatic return time to Measuring Mode The display goes back automatically to Measuring Mode if the front buttons are left untouched for the specified time period while it is in one of the setting modes (except the loop test output mode).
  • Page 30 47DV • BCD output DATA signal is established in approx. 30 milliseconds upon detecting the falling pulse edge of REQ signal (REQ, MAX_REQ, MIN_REQ) and DAV turns on. Read in the data while the DAV is ON. RUN signal turns off in case of errors other than the scaling error. DATA and DAV signals turn off while RUN signal is OFF. The last measured value is held when HOLD signal turns on. All BCD signals turn off when RESET signal turns on. Data is in the negative range when POL signal is ON, in the positive range with OFF. OVER signal turns on in case of the scaling error. While in the loop test output mode, the analog/alarm outputs are provided according to the display reading, even when REQ signals are turned on.
