}
In this logic, the user inputs of the
meter are internally pulled up to +5 V
with 22 K resistance. The input is active
when it is pulled low (<0 .9 V).
3.3 USER INPUT WIRING
Before connecting the wires, the User Input Logic Jumper should be verified for proper position. If not using User
Inputs, then skip this section. Only the appropriate User Input terminal has to be wired.
Sourcing Logic
Terminal 8-10: + VDC thru external switching device
Terminal 7: -VDC thru external switching device
In this logic, the user inputs of the meter are
internally pulled down to 0 V with 22 K
resistance. The input is active when a voltage
greater than 3.6 VDC is applied.
Connect external switching device between
appropriate User Input terminal and User Comm.
Sourcing Logic
Terminals 9-11:
+ VDC through external switching device
Terminal 8:
-VDC through external switching device
In this logic, the user inputs of the meter are
internally pulled down with 22 K resistance.
The input is active when a voltage greater
than 3.6 VDC is applied.
