Configuring relay outputs using the display

You can use the front panel to configure the relay outputs.
NOTE: It is recommended you use ION Setup to configure the relay 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 > Relay.
  4. Move the cursor to point to the relay output you want to set up, then press Edit.
  5. Move the cursor to point to the parameter you want to modify, then press Edit.
    NOTE: If Edit is not displayed, it means the parameter is either read-only or can only be modified through software.
  6. Modify the parameter as required, then press OK.
  7. Move the cursor to point to the next parameter you want to modify, press Edit, make your changes, then press OK.
  8. Press the up arrow to exit, then press Yes to save your changes.

    Relay output setup parameters available through the display

    Parameter Values Description

    Label

    Use this field to change the default label and assign a descriptive name to this relay output.

    Control Mode

    External, Alarm

    This field displays how the relay output functions.

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

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

    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 relay output remains in the closed state until an open command is sent by the computer or PLC. In the event of trigger for Alarm mode, the relay output remains in the closed state until the drop out point is crossed.

    • Timed: the relay 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 relay 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 65535

    This setting defines the pulse width (ON time) in seconds.

    Select Alarms

    All available alarms

    Applies when Control Mode is set to Alarm. Select one or more alarms to monitor.
