  • Page 28: Alarm Output

    Alarm1 and A2/EXT can be associated with alarm state and/or excitation control. Please refer to Alarm Output and Excitation Control for details. Alarm Output The logger will be in a state of alarm if ALL of the following conditions are met: 1.
  • Page 29 terminal and low-alarm state controls A1 terminal. High alarm and low alarm -> Alarm1 Both high and low alarm states control A1 terminal. Excitation control -> A2/EXT Excitation controls A2/EXT terminal. Excitation control -> A2/EXT and both alarms -> Excitation controls A2/EXT and both Alarm1 high and low alarm states control Alarm1 terminal.

  • Page 30: Excitation Output

    Alarm1 is used as switch of the power supply. Excitation Output Excitation output is used when you need to save the electric power of the device that provides the signal source to the data logger. When there is no local power available and a battery pack is used to power the transducer, excitation control greatly reduces power consumption.
