EMERSON Rosemount 752 Remote Indicator

Safety messages

This guide provides basic guidelines for Rosemount 752 Remote Indicator. It does not provide instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-proof, Flameproof, or intrinsically safe (I.S.) installations. Refer to the Rosemount 752 Reference Manual for more instruction. This manual is also available electronically on Emerson.com/Rosemount.

WARNING

Explosions could result in death or serious injury.
Installation of this indicator in an explosive environment must be in accordance with the appropriate local, national, and international standards, codes, and practices. Review the Product Certifications section for any restrictions associated with a safe installation.

• Before connecting a communicator in an explosive atmosphere, ensure the instruments in the segment are installed in accordance with intrinsically safe or non-incendive field wiring practices.
• In an explosion-proof/flameproof installation, do not remove the indicator cover when power is applied to the unit.

Electrical shock can result in death or serious injury.

• Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock.

Conduit/cables entries

• Unless marked, the conduit/cable entries in the housing use a ½–14 NPT thread form. Entries marked “M20” are M20 × 1.5 thread form. On devices with multiple conduit entries, all entries will have the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.
• When installing in a hazardous location, use only appropriately listed or Ex certified plugs, glands, or adapters in cable/conduit entries.

Wiring connection

Wiring for FOUNDATION™ Fieldbus protocol

1. Remove the housing cover on terminal compartment side.
   Note
   Do not remove the cover in explosive atmospheres when the circuit is live. Signal wiring supplies all power to the indicator.

2. Connect the power leads to the terminals marked “FIELDBUS WIRING” as shown in Figure 1-1.
   Note
   The power terminals are not polarity sensitive.

3. Plug and seal unused conduit connections on the indicator housing to avoid moisture accumulation in the terminal side.

   • If you do not seal unused connections, mount the indicator with the electrical housing positioned downward for drainage.
   • Install wiring with a drip loop.
   • Arrange the drip loop so the bottom is lower than the conduit connections and the indicator housing.

Note
Do not apply high voltage (e.g. ac line voltage) to the indicator terminals. Abnormally high voltage can damage the unit. Indicator terminals are rated to 32 Vdc.

Fieldbus Terminal Block

Electrical considerations
Proper electrical installation is necessary to prevent errors due to improper grounding and electrical noise. Shielded, twisted pair cable should be used for best results in electrically noisy environments. Cable type A is recommended by FOUNDATION™ Fieldbus protocol.

Power supply
The indicator requires between 9 and 32 Vdc (9 and 15 Vdc for FISCO) to operate and provide complete functionality. The dc power supply should provide power with less than two percent ripple.

Power conditioner
A Fieldbus segment requires a power conditioner to isolate the power supply, filter, and decouple the segment from other segments attached to the same power supply.

Grounding
Signal wiring of the Fieldbus segment cannot be grounded. Grounding out one of the signal wires will shut down the entire FOUNDATION™ Fieldbus segment.

Shield wire ground
To protect the Fieldbus segment from noise, grounding techniques for shield wire usually require a single grounding point for shield wire to avoid creating a ground loop. The ground point is typically at the power supply.

FOUNDATION Fieldbus Indicator Field Wiring

Intrinsically safe installations may allow fewer devices per I.S. barrier due to current limitations.

• A. Power supply
• B. Integrated power conditioner and filter
• C. 6234 ft. (1900 m) max (depending upon cable characteristics)
• D. Terminators
• E. Fieldbus segment
• F. Trunk(1)
• G. FOUNDATION™ Fieldbus configuration tool
• H. Spur
• I. Signal wiring
• J. Fieldbus devices on segment

1. The power supply, filter, first terminator, and configuration tool are typically located in the control room.

Surges/transients
The indicator will withstand electrical transients of the energy level usually encountered in static discharges or induced switching transients. However, high-energy transients, such as those induced in wiring from nearby lightning strikes, can damage the indicator.

Optional transient protection terminal block
The transient protection terminal block can be ordered as an installed option (option code T1 in the indicator model number) or as a spare part. The spare part number is 03151-4131-0002. The lightning bolt symbol shown identifies it as a transient protection terminal block.

Note
The Fieldbus physical layer specification requires indicator communication during extreme operating conditions of 250 Vrms common mode signal. The transient terminal block was designed to limit common mode voltages to 90 V and cannot be used in these extreme operating conditions.

Grounding the indicator case

Always ground the indicator case in accordance with national and local electrical codes. The most effective indicator case grounding method is a direct connection to earth ground with minimal impedance. Methods for grounding the indicator case include:

Internal ground connection
The internal ground connection screw is inside the terminal side of the electronics housing. The screw is identified by a ground symbol ( ), and is standard on the Rosemount 752 Remote Indicators.

External ground assembly
Ground screw is located at the bottom of the mounting bracket.

Note
Grounding the indicator case using the threaded conduit connection may not provide a sufficient ground. The transient protection terminal block (option code T1) will not provide transient protection unless the indicator case is properly grounded. Use the above guidelines to ground the indicator case. Do not run transient protection ground wire with signal wiring; the ground wire may carry excessive current if a lightning strike occurs.

Configure the transducer block

The LCD display transducer block can be configured to sequence eight different process variables. If a function block is scheduled in the Rosemount 752 that links a process variable from another device on the segment, that process variable can be displayed on the LCD display. To configure the Rosemount 752 Fieldbus Indicator use any FOUNDATION™ Fieldbus configuration tool to modify the configuration parameters for each value that is to be displayed.

Configuration parameters

Note
Some host systems may ask for the device’s capability level during commissioning. If prompted, the correct value to enter for the Rosemount 752 is 1.

DISPLAY_PARAM_SEL
The DISPLAY_PARAM_SEL parameter specifies how many process variables willbe displayed. Select up to eight display parameters.

BLKTAG#
Enter the Block Tag of the function block that contains the parameter to be displayed. The default function block tags from the factory are:

• PID_1200_XXXX
• ISEL_1300_XXXX
• CHAR_1400_XXXX
• ARITH_1500_XXXX
• INTEG_1600_XXXX

Note
XXXX represents the last four digits of the device ID.

BLKTYPE#
Enter the Block Type of the function block that contains the parameter to be displayed. (e.g. ISEL PID, etc.)

PARAMINDEX#
Choose the parameter to be displayed.

CUSTOMTAG#
The CUSTOMTAG# is an optional user-specified tag identifier that can be configured to be displayed with the parameter in place of the block tag. Enter a tag of up to five characters.

UNITSTYPE#
The UNITSTYPE# parameter is generally selected via a drop-down menu with three options: AUTO, CUSTOM, or NONE. Select CUSTOM and be sure to configure the CUSTOMUNITS# parameter. Select NONE if the parameter is to be displayed without associated units.

CUSTOMUNITS#
Specify custom units to be displayed with the parameter. Enter up to six characters. To display Custom Units the UNITSTYPE# must be set to CUSTOM.

Note
_# represents the specified parameter number.
