Page 3: Description
This, together with the low voltage drop introduced by each input in the 4/20mA loop, simplifies application and documentation. The BA329 is powered by a BEKA power isolator located in a safe area, or in Zone 2 if mounted within an enclosure providing IP54 protection. - Page 4 When a BA329 Indicator is operating, the function of each touch button is shown by the colour of the buttons backlight. Green The touch button controls how the adjacent input is displayed. For screen layouts where the display(s) are not adjacent to the touch buttons, the buttons are in the same vertical order as the displays.
