PART III - PROGRAMMING
Basic Programming
Tools Required:
Programming Flowchart (see Flowchart 1, page 21)
Programming of the One Series is accomplished using the two buttons on the faceplate (labeled
2
and
g
see Figure 12). Stepping
down through the main menu using the left
2
button, you can access the various commands of the One Series software menu. The right
button is then used to move into the command submenu for setting up or modifying the parameters.
NOTE:
The flowchart on page 21 shows the enitre programming commands menu structure. Before removing the enclosure cover,
please read the instructions on page 5. The One Series programming menu is a single direction lop, with submenus embedded within,
so there is no way to back up in the program. If you need to make a correction to a prior Main Menu step, you will need to continue
forward, exit, then re-enter the program to step through to the appropriate feature. If you are in a Submenu, you will need to continue
to the beginning of the menu item and re-enter the Submenu to make the correction.
Entering the Programming Mode
NOTE:
While in the Programming Mode, the One Series will remove itself from service (go offline). All outputs are set to the fail safe
state and the One Series ignores process variable input from the process sensor. The IAW
®
Output signal will open. The switch output
failsafe state will be based on the programmed operating mode of the switch. For example, the failsafe state for “Open on” modes is
open. The control system will interpret these signals as a detected fault and a process upset (set point reached) simultaneously.
It is
essential to alert the control system operators before entering the Programming Mode.
Use the Flowchart on page 21 as a guide through the various commands in the Programming Mode.
• Press and release both buttons
2g
simultaneously and then press the right button
g
to enter the password.
• Enter the 4-digit password. The factory defualt password is “0000”.
• The left
2
button increments the blinking digit.
• The right
g
button sets the digit and moves to the next.
• Once a valid password is entered, “OK” will appear on the display.
• Press and release the right
g
button.
• CLR MAX/MIN (or MAN RSET if Latch is set) will appear on the display.
This is the first command prompt in the Programming Mode.
NOTE:
The One Series will automatically exit the Programming Mode and resume monitoring the process (go back online) if two minutes
elapse without a button being pressed. The One Series recalls all previously saved parameters from memory and any program changes
that were made will be discarded. This two-minute timeout feature prevents the One Series from being left offline accidentally.
Exiting the Programming Mode
When any of the programming commands are displayed, it is possible to escape and exit the Programming Mode by pressing the left
2
and right
g
button simultaneously. Doing this redirects the program to the Save Changes menu location, which is only possible at
menu actions indicated by an asterisk (*) on the Programming Flowchart, found on page 21.
NOTE:
It is also possible to exit the Programming Mode by repeatedly pressing the left
2
button from any programming command until
the Save Changes menu location is reached.
Saving Programming Changes
When changes have been made to the programming settings, a choice is provided to Save or Discard the changes. At any prompt:
• Press both left
2
and right
g
buttons to display SAVE CHNG menu.
To Save changes, press the right
g
button. NO (the default) will be displayed.
• Press the left
2
button to toggle and display YES.
• Then press both left
2
and right
g
buttons to confirm, save the changes and return to the Process Display mode.
The One Series will resume process monitoring (go back online) using the new programming parameters.
To Discard changes, press the right
g
button. NO will be displayed.
• Press both left
2
and right
g
buttons to confirm, discard changes and return to the Process Display mode.
The One Series will resume monitoring the process (go back online) recalling all previously saved parameters from memory.
