IMPORTANT NOTICEThis installation guide provides basic guidelines for Rosemount® 751 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 751 reference manual (document number 00809-0100-4378) for more instruction. This manual is also available electronically on www.rosemount.com.

WARNINGExplosions 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. Please review the approvals section of the Rosemount 751 reference manual for any restrictions associated with a safe installation.

• 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.

Rosemount 751

STEP 1: INSTALLATION

AssemblyThe Rosemount 751 Field Signal Indicator is comprised of the componentsshown in Figure 1. The housing may contain an analog or LCD meter. Bothmeters are independent of component parts and are completelyinterchangeable. Both meters plug into the terminal screws on the housing, asshown in Figure 1.The meter subassembly contains the components shown in Figure 2.Figure 1. Rosemount 751 Exploded View

Rosemount 751Wiring DiagramsUse the following wiring diagrams to wire the Rosemount 751 Field Signal Indicator, in series or in parallel, with Rosemount transmitters. Use shielded cable for best results in electrically noisy environments.It is recommended that the 751 indicator be wired in a series configuration when the 4-20 mA transmitter does not contain a test terminal. The 751 is designed so the analog or LCD meter can be removed from the housing without impacting the integrity of the 4-20 mA loop. Removal of the entire 751 device from the series configuration will disrupt the loop.Figure 3. Rosemount 751 Series Wiring Diagrams

It is recommended that the 751 indicator be wired in a parallel configuration when the 4-20 mA transmitter includes a test terminal. Utilization of the test terminal is required in a parallel configuration. Connecting the 751 indicator across the positive and negative terminals of the 4-20 mA transmitter could impact the loop.A parallel configuration will allow the removal of the 751 indicator without affecting the integrity of the 4-20 mA loop. Additionally, spare 751 indicators can be added without disrupting the loop.Figure 4. Rosemount 751 Parallel Wiring Diagrams

STEP 2: CONFIGURATION

LCD Meter ConfigurationThe 20-segment bar graph is factory calibrated and represents 4–20 mA directly, but the end points of the LCD meter are user-definable. The meter requires a current between 4 and 20 mA in order to be scaled, but the actual value of the current is not significant.

Remove the Cover

1. Unscrew and remove the transparent housing cover from the LCD meter body.

Position the Decimal Point and Select the Meter Function2. Press the left and right configuration buttons simultaneously and release them

immediately.3. To move the decimal point to the desired location, press the left configuration button.

Note that the decimal point wraps around.4. To scroll through the mode options, press the right configuration button repeatedly until

the meter displays the desired mode (See Table 2-1).

NOTEThe LCD meter time-out is approximately 16 seconds. If you do not press the configuration buttons within 16 seconds, the indicator will revert to reading the current signal.

Store the Information5. Press both configuration buttons simultaneously for two seconds. Note that the meter

displays “- -” for approximately 7.5 seconds while the information is being stored.

Set the Display Equivalent to a 4 mA Signal6. Press the left configuration button for two seconds.7. To decrease the display numbers, press the left configuration button. To increase the

numbers, press the right configuration button. Set the numbers between –999 and 1000.8. To store the information, simultaneously press both configuration buttons for two

seconds.

WARNINGExplosions can result in death or serious injury. Do not remove the instrument cover in explosive environments when the circuit is alive.

Table 1. LCD Meter Mode OptionsOptions Relationship between Input Signal and Digital Display

L in LinearLinF Linear with five-second filterSrt Square rootSrtF Square root with five-second filterSquare root function only relates to the digital display. The bar graph output remainslinear with the current signal.Square root responseThe digital display will be proportional to the square root of the input current where 4 mA = 0 and 20 mA = 1.0, scaled per the calibration procedure. The transition point from linear to square root is at 25 percent of full scale flow.Filter response operates upon “present input” and “input received in the previous fivesecond interval” in the following manner:

Display = (0.75 previous input) + (0.25 present input)This relationship is maintained provided that the previous reading minus the presentreading is less than 25 percent of full scale.

Set the Display Equivalent to a 20 mA Signal9. Press the right configuration button for two seconds.10.To decrease the display numbers, press the left configuration button. To increase the

numbers, press the right configuration button. Set the numbers between –999 and 9999. The sum of the 4 mA point and the span must not exceed 9999.

11. To store the information, simultaneously press both configuration buttons for two seconds. The LCD meter is now configured.

Replace the Cover12.Make sure the rubber gasket is seated properly, and thread the transparent housing

cover onto the LCD meter body.
