Quick Start Guide
NOTICE
Installation of the ferrite clamp over the 4-20 mA out wires is
required for the compliance with the European EMC directive.
4. Terminate the shield of the 4-20 mA signal wires at the designated
ground terminal of the Rosemount 6888 Xi. Do not allow bare shield
wires to contact the circuit boards. Insulate the shield wires prior to
termination.
5. Connect the signal wires from the Rosemount SPS or Rosemount
IMPS (if used) to the applicable terminals of J3.
Refer to the
reference manual for wiring details.
6. Reinstall the I/O board in the card rack of the Rosemount 6888 Xi.
7. If your system is configured or two channel operation, repeat
through
8. Remove the probe's connector from the power supply board located
on the left side of the card rack inside the Rosemount 6888Xi.
9. Connect the line, or L1, wire to the L1 terminal and the neutral, or L2,
wire to the N terminal.
10. Reinstall the power supply connector in the power supply board.
1.2.3 Wire transmitter probe with integral autocal and HART
communications
You can initiate calibration 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. You can only implement the integral autocal feature when using the
probe with the Rosemount 6888 Xi.
Procedure
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 6888A accepts line voltage at 120/240 Vac ±10%,
50/60 Hz. No setup is required.
3. Connect the 4-20 mA signal wires form the Rosemount 6888 Xi to
the connections in the side chamber of the transmitter.
Do not connect the signal wires to the terminals in the main chamber
where the AC input wires are connected. Use a shielded twisted wire
pair. Do not allow bare shield wires to contact the circuit boards.
