Appendix A
FailSafe Mode
FailSafe High mode (FSH) is the factory default, and it links menus 07 and 17, and 08 and
18, to enable analog 2-state and digital fault signalling.

Either FailSafe High or FailSafe
Low can be selected at menu 1E.
In FailSafe High mode (FSH):
• Highest current (20 mA), closed solid-state switch in safe condition when probe
is uncovered.
• Low Signal current (3.6 mA), solid-state switch open when fault/error occurs.
In FailSafe Low mode (FSL):
• Lowest current (4 mA), open solid-state in safe conditions when probe is
uncovered.
• High Signal current (22mA)/ solid-state closed when fault/error occurs.
1. Set the rotary switch to E.
2. Press and hold the RED (+) button for FailSafe High.
or: Press and hold the BLUE (–) button for FailSafe Low.
or: Press and hold both buttons simultaneously to reset to Free Programming
Mode.

FailSafe Mode at menu 1E provides a shortcut, by contrast with Free Programming
Mode where all menu items are completely independent. You can make the same
selections in FPM, but you need to set each menu item individually.
