Selecting A New Setting From A List Of Choices; Three Button Operation With No Display Installed; Zero Adjustment; Span Adjustment - Honeywell SMV800 SmartLine User Manual

9.2.6 Selecting a new setting from a list of choices

Use the procedure described below to select a new setting for parameters that present a list of
choices (e.g., PV Display, Pressure Units, etc.)

1. Press to begin the edit process.
2. Press the  or  buttons to scroll through the list of choices.

3. Press to make your selection. The new selection will be stored in the transmitter and
displayed on the lower line, right justified.

9.2.7 Three Button Operation with no Display Installed

When there is no Display installed, the buttons can be used to perform a Zero or Span adjustment of
the Transmitter (Not applicable for Modbus). Caution should be taken to ensure these adjustments are
only made when the correct input pressures are applied. This is not applicable for Modbus.

9.2.8 Zero Adjustment

This adjustment is the same as performing a Set LRV using the Display.
1. Connect a current meter or voltmeter as shown in Figure 19 to monitor the PV output of the
Transmitter.
2. Using an accurate pressure source, apply pressure equivalent to the Transmitter LRV.
3. Press the Down (
Verify that the output is now 4 mA.

9.2.9 Span Adjustment

This adjustment is the same as performing a Set URV using the Display.
1. Connect a current meter or voltmeter as shown in Figure 19 to monitor the PV output of the
Transmitter.
2. Using an accurate pressure source, apply pressure equivalent to the desired Upper Range
Value of the transmitter.
3. Press the Down (
4. Verify that the PV output is now 20 mA.
Use SmartLine Versatilis Modem and application to make adjustments to an SMV800
SmartLine Multivariable Transmitter for HART and DE models, and Honeywell Modbus
configuration tool for Modbus. Alternately, certain adjustments are possible through an
Experion Station or Universal Station, if the SMV800 is digitally integrated with either of
these stations.

9.3 Changing the Default Failsafe Direction

Note: Not applicable for Modbus.
Transmitters are shipped with a default failsafe direction of upscale. This means that the Transmitter
output will set the current output to upscale failsafe (maximum output) upon detection of a critical
status. You can change the direction from upscale failsafe to downscale failsafe (minimum output) by
moving the top jumper located in the Electronics module.
