4.3 USER INPUT WIRING
If User Input 1 and/or 2 are wired for quadrature or directional counting, an additional switching device should not be
connected to that User Input terminal. User Input terminal does not need to be wired in order to remain in inactive state.
Sourcing Logic (USrACt HI)
When the USrACt parameter is programmed
to HI, the user inputs of the meter are
internally pulled down to 0 V with 20 KW
resistance. The input is active when a
voltage greater than 2.2 VDC is applied.

Sinking Logic (USrACt LO)
When the USrACt parameter is programmed
to LO, the user inputs of the meter are
internally pulled up to +3.3 V with 20 KW
resistance. The input is active when it is
pulled low (<1.1 V).

DISPLAY LINE 1
Line 1 is the large, 6-digit top line display. Counter values, rate values and the
maximum (Hi) and minimum (Lo) rate capture values can be shown on Line 1.
The 3-digit Units mnemonic characters can be used to indicate which Line 1
display value is shown. Standard or custom mnemonics are available for the
Line 1 values. See Line 1 parameters in the Display Parameters programming
section for configuration details.
DISPLAY LINE 2
Line 2 is the smaller, 9-digit bottom line display. Counter values, rate values,
rate capture values, setpoint values and parameter List A/B status can all be
shown on the Line 2 display. The display loops described below are used to
view, reset and modify the selected display values, based on the Line 2 Value
Access setting programmed for each available value. See Line 2 parameters in
the Display Parameters programming section for configuration details.
