Configuring digital inputs using the display

You can use the display to configure the digital inputs.

NOTE: It is recommended you use ION Setup to configure the digital inputs, as setup parameters that require text entry can only be modified using ION Setup.

Navigate to Maint > Setup.
Enter the setup passcode (default is “0”), then press OK.
Navigate to I/O > D In.
Move the cursor to point to the digital input you want to set up, then press Edit.
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.
Modify the parameter as required, then press OK.
Move the cursor to point to the next parameter you want to modify, press Edit, make your changes, then press OK.

Press the up arrow to exit. Press Yes to save your changes.

Debounce Time (ms)	0 to 1000	Debounce is the time delay that compensates for mechanical contact bounce. Use this field to set how long (in milliseconds) the external signal must remain in a certain state to be considered a valid state change.

Normal: the digital input is either associated with a digital input alarm, or it is not associated with another meter function. The meter counts and records the number of incoming pulses normally. Demand Sync: the digital input is associated with one of the input sync demand functions. The meter uses the incoming pulse to synchronize its demand period with the external source. Input Metering: the digital input is associated with one of the input metering channels. The meter counts and records the number of incoming pulses and related consumption data associated with the pulses. Multi-Tariff: the digital input is associated with the multi-tariff function.
