WellTell-X Host Communication Wiring

NOTE: If the unit came preconfigured from the factory, ignore the

following wiring instructions.

Wiring of the WellTell-X host to a parent device (XFC/XRC) is fairly

simple. In the example (see Figure 6), an XFC-195 board is used as the

parent meter. If the application involves something other than the XFC-

195, please check the meter pinouts before proceeding.

Additionally, the following example uses COM 2 of the XFC. COM 1 is

often defaulted for communication with a remote device (radio, modem,

etc.). Wiring is simplified by the use of pre-wired cable that is designed

specifically for the WellTell-X device.

Step 4

Configuring COM 2 for the LevelMaster Application

After completing the electrical wiring for the WellTell-X to COM 2 on the

flow computer, the user needs to configure the COM 2 communication

port.

NOTE: In Figure 6, COM 2 (XA2) must have an RS-485 module inserted.

Figure 7 walks the user through the steps (A and B) to configure COM 2

for the LevelMaster application.
