Meriam 4150X ATEX I.S. Certified HART Communicator - Manual (Page 13)

9
1 Lockout: Indicates Enable / Disable status of Master Lockout feature.
2 PV Prompt: In addition to the primary variable, multivariable HART devices have secondary,
tertiary, and sometimes more variables. When PV Prompt on the Lockout screen is
“Disabled” and a Save command is issued by the 4150 / 4150X, the handheld saves only the
primary variable. When PV Prompt is “Enabled” and a Save command is issued, the
handheld saves the HART parameter information for all variables present. The factory
default for PV Prompt on the Lockout screen is “Disabled”.
3 View Details: This option takes the user to the Lockout Details screen listing all 4150 / 4150X
parameters that can be protected by lockout (see above right). Individual functions can be locked or,
if preferred, the lockout can be set to deny unauthorized access to all parameters. Press the number of
the desired menu item to toggle between Enabled and Disabled. Once satisfied with the setting, press
the Back soft key to return to the Lockouts screen.
To enable the lockout options selected, be sure the display reads “1 Lockout: Enabled”. If it does not, press
the Chng soft key to toggle from “Disabled” to “Enabled”. A prompt will appear to “Enter Code: 0 0 0”.
Lockout Code
At this point the user will be prompted to enter a 3-digit lockout code. This code will be required to gain
access and change any menu item previously locked out. The number keys of the unit will not work here.
Use the Increment, Decrement and Next Soft Keys to input a lockout code value. Alternatively you may use
the green keys for Increment and Decrement functions. When you are satisfied with the
lockout code value, press Store. IMPORTANT: After the code is entered, the user must cycle the power to
activate the lockout!
BE SURE TO SAVE THIS CODE IN A SAFE PLACE IN THE EVENT YOU FORGET THE
NUMBER. ACCESS TO LOCKED-OUT FEATURES WILL BE DENIED WITHOUT THE PROPER CODE.
Note: the 4150 / 4150X is shipped with a factory lockout code of 3 2 1. The user must enter this code the
first time Lockout is used.
Disable Lockout
When you wish to use a function or edit a value that is protected by the lockout code, enter the three digit
Lockout code when prompted and press Save. You will now be able to use the function or edit the setting as
normal. Entering an incorrect code will display the message “Incorrect Code” and allow you to try again.
Changing the Lockout Code
To change the lockout code, disable the lockout function for all the parameters selected, shut the unit off, and
follow the procedures outlined above.
