Oxymitter 4000

Instruction Manual

IB-106-340 Rev. 2.4 April, 2001

5-3 HART COMMUNICATOR PC CONNECTIONS

There is an option to interface the HART Com- municator with a personal computer. Load the designated AMS software into the PC. Then link the HART Communicator to the PC using the interface PC adapter that connects to the serial port (on the communicator rear panel).

Refer to the proper HART Communicator docu- mentation in regard to the PC interface option.

5-4 OFF-LINE AND ON-LINE OPERATIONS

The HART Communicator can be operated both off-line and on-line.

a.Off-line operations are those in which the communicator is not connected to the Oxy- mitter 4000. Off-line operations can include interfacing the HART Communicator with a PC (refer to applicable HART documenta- tion regarding HART/PC applications.

b.In the on-line mode, the communicator is connected to the 4-20 mA analog output sig- nal line. The communicator is connected in parallel to the Oxymitter 4000 or in parallel to the 250 ohm load resistor.

NOTE

If the HART Communicator is turned on while connected to the 4-20 mA

analog output signal line, an undefined status indication appears while the communicator warms up. Wait until the warmup period ends to continue.

c. The opening menu displayed on the LCD is different for on-line and off-line operations. When powering up a disconnected (off-line) communicator, the LCD will display the Main Menu. When powering up a connected (on-line) communicator, the LCD will display the On-line Menu. Refer to the HART Communicator manual for detailed menu information.

5-5 LOGIC I/O CONIFGURATIONS

 

The Oxymitter 4000 logic I/O output can be

 

configured for ten different modes through

 

HART/AMS. The factory default condition is

 

Mode 5. A list of possible configurations appear

 

in Table 5-1.

5

The Unit Alarm configuration available for Modes 1, 3, 5, and 7 refers to the diagnostic alarm faults in Table 7-1.
