Configuring digital outputs using the display

You can use the display to configure the digital outputs.
NOTE: It is recommended you use ION Setup to configure the digital outputs, as setup parameters that require text entry can only be modified using software.
  1. Navigate to Maint > Setup.
  2. Enter the setup password (default is “0”), then press OK.
  3. Navigate to I/O > D Out.
  4. Move the cursor to point to the digital output you want to set up, then press Edit.
  5. Edit the parameters as required.
    1. Move the cursor to point to the parameter you want to modify, then press Edit
    2. Modify the parameter as required, then press OK.
    3. Move the cursor to point to the next parameter you want to modify, press Edit, make your changes, then press OK.
    NOTE: If Edit is not displayed, it means the parameter is either read-only or can only be modified through software.
  6. Press the up arrow to exit. Press Yes to save your changes.

    Digital output setup parameters available through the display

    Setting Option or range Description

    Label

    This can be modified only through software. Use this field to change the default label and assign a descriptive name to this digital output.

    Control Mode

    External, Demand Sync, 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 Sync: 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.
