    Description

    Label Use this field to change the default label and assign a descriptive name to this digital output.
    Control Mode External, Demand, Alarm, Energy

    This field displays how the digital output functions.

    • External: the digital output is controlled remotely either through software or by a PLC using commands sent through communications.

    • Demand: the digital output is associated with one of the demand systems. The meter sends a pulse to the digital output port at the end of every demand interval.

    • Alarm: the digital input is associated with the alarm system. The meter sends a pulse to the digital output port when the alarm is triggered.

    • Energy: The digital output is associated with energy pulsing. When this mode is selected, you can select the energy parameter and the set the pulse rate (pulses/kW).

    Behavior Mode Normal, Timed, Coil Hold
    • Normal: this mode applies when control mode is set to External or Alarm. In the event of trigger for External mode, the digital output remains in the ON state until an OFF command is sent by the computer or PLC. In the event of trigger for Alarm mode, the digital output remains in the ON state until the drop out point is crossed.

    • Timed: the digital output remains ON for the period defined by the On Time setup register.

    • Coil Hold: this mode applies when control mode is set to External or Alarm. For a unary alarm that is associated with a digital output, you must set Behavior Mode to Coil Hold. The output turns on when the “energize” command is received and turns off when the “coil hold release” command is received. In the event of a control power loss, the output remembers and returns to the state it was in when control power was lost.

    On Time (s) 0 to 9999 This setting defines the pulse width (ON time) in seconds.
    NOTE: In energy mode, the digital output pulse ON time is fixed for 20 ms.
    Select Dmd System Power, Current Applies when Control Mode is set to Demand Sync. Select the demand system to monitor.
    Select Alarms All available alarms Applies when Control Mode is set to Alarm. Select one or more alarms to monitor.
    Associations This field displays additional information if the digital output is already associated with another meter function.
