When connecting the 4150 / 4150X to a loop with a resistive load greater than 250 Ωs, the HART jacks may
be connected across the loop + and – or to the HART device communication terminals. Refer to the
following diagram for connecting across the loop + and -.

Initial Screens / Online Mode
Upon power up the 4150 / 4150X automatically detects if a field device is connected and attempts to
establish HART communications; this is the factory default “Auto” poll function. When a device with
address zero is found, the 4150 / 4150X provides feedback to the user and starts the initial HART display for
the connected device. See an example of Online Mode below.
