DIP Switches
The Hardware Lockout/Battery Backup DIP Switch
All units are equipped with a DIP switch for hardware lockout of the SEt
and Fcty prompt menus, and to enable battery backup of the Run parame-
ters. The location of the board and switch appear below. The switches are
clearly numbered, and are labeled on the outside of the board. When
Switch #1 is on, battery backup is enabled. When Switch #2 is on, the
menus under the SEt prompt (Input, Output, Global and Communications)
and Fcty prompt (Diagnostics and Calibration) cannot be viewed. When the
control leaves the factory switch #1 is off and switch #2 is off.
