Lockouts
The MFT HART Communicator can be programmed to lock out all
adjustable functions or only certain functions that a supervisor may wish
to control. These are Enabled or Disabled individually on the Lockout
Details screen shown at right. To access, select the Lockouts option,
and finally the View Details option. “Disable” on this screen means the
particular menu function will not be locked out and “Enabled” means the
particular menu function will be locked out once the Master Lockout is
Enabled. Move the cursor to the desired line and use the Chng soft key
to change the status of each line.
All - all MFT functions listed on Lockout Details screen
Zero - zeroing of installed sensor modules and integral volts / current
(see the “Zero” section of this manual for details)
Recal - Rcal feature of MFT (see the “Rcal” section of this manual for
details)
Settings - clock, timers, battery type, PC comm mode
Units - changing units of measure for sensor modules and integral volts / current meter
DOFs - the ability to install new DOFs (MFT 4010 only)
Configs - the ability to edit saved configurations in Offline mode (MFT 4010 only)
Firmware - the ability to install new firmware
PV Prompt - the ability to lock out the PV Prompt (see the “Saving Configurations for Multivariable HART
Devices PV Prompt” section of this manual for more details) (MFT 4010 only)
Master Lockout
Once the Lockout Detail status (Disable or Enabled) is correct, select the
Back soft key to arrive at the Current Settings screen shown at right. To
activate the lockout features previously selected on the Lockout Details
screen, move the cursor to the Lockout option line and press the Chng
soft key. If there is an active Lockout code, then the display will prompt
the user to enter the code. Use the Inc, Dec, Next, and Store soft keys to
enter and store a 3-digit code. If no Lockout code is active, then using the
Chng soft key to change the status to Enable will cause the unit to request
a 3-digit lockout code of the user’s choosing. Once the code is stored and
power is cycled, all Lockout Details selected are locked out from use.
PV Prompt
PV Prompt option on this display allows the user to “Disable” the PV Prompt question for multivariable
HART devices or to “Enable” the display of this question and its capabilities. The question reads:
“Multivariable device, allow PV changes? Yes / No”
See the “Saving Configurations for Multivariable HART Devices” section of this manual for more details.
Unlocking the MFT
To perform any changes to the MFT’s settings when lockout is engaged the user will be prompted to input
the lockout code prior to allowing any changes. Use the Increment, Decrement and Next Soft Keys to input
a lockout code value. When you are satisfied with the lockout code value, press Store to unlock the MFT.
Changing the Lockout Code
To change the lockout code, disable the Master Lockout option on the Current Settings screen. You will be
prompted for the old code before any change is made. Press the Chng soft key until Enable is displayed
again and then press the Chng one more time. The unit will prompt for entry of a new 3-digit code. Press
Store soft key and cycle power to complete.
Important note: All MFT units are shipped with the PV Prompt locked out with a lockout code of 3-2-
1. See the “Saving Configurations for Multivariable HART Devices” section of this manual for more
information on PV Prompt
