Emerson Rosemount 6888C, Instruction Manual

Page: 34 / 88

NOTICE
A. Except for JP5, JP7, and JP8 on IO board, jumper and switch settings are factory set and are
shown for reference only.
B. IO board: 4-20 mA/HART loop power settings
• JP5
— Pins 1-2: internal power Rosemount 6888 Xi to Rosemount 6888 transmitter
— Pins 2-5: external power Rosemount 6888 Xi to Rosemount 6888 transmitter (requires
2,500 resistor across J4, PR+ to PR-)
• JP7/JP8
— Pins 1-2: internal power to DCS
— Pins 2-3: external power Rosemount 6888 Xi to DCS
NOTICE
I/O board - Channel 2 is a duplicate of Channel 1.
4.7 Connecting the Transmitter probe with
integral autocal to FOUNDATION Fieldbus
™
communications
This probe contains gas-switching solenoids so that the Rosemount 6888 Xi Electronics,
Field Communicator, or AMS can control the introduction of calibration gases. Calibrations
can be initiated via a calibration recommended diagnostic, time since last calibration,
manually via external dry contact, HART communications, or from the Rosemount 6888 Xi
local operator interface keypad. The integral autocal feature can only be implemented
when the probe is used with a Rosemount 6888 Xi.
1. Remove the two covers from the transmitter.
2. Connect the line (L1 wire) to the L1 terminal, the neutral (L2) wire to the L2/N terminal,
and the ground wire to the ground lug.
The Rosemount 6888C accepts line voltage at 120/240 Vac ±10%, 50/60 Hz. No setup
is required.
3. Connect the FOUNDATION Fieldbus wires from the Rosemount 6888 side housing to
the FF segment.
Note that the Rosemount 6888 probe is not rated as intrinsically safe and will render
any IS or FISCO segment it is wired to as non-IS. Use a shielded twisted wire pair. Do not
allow bare shield wires to contact the circuit boards.
4. Terminate the shield at both the probe and the Rosemount 6888 Xi Advanced
Electronics.
NOTICE
The FOUNDATION Fieldbus signal represents the O
2
value and also powers the probe-
mounted electronics.
