Reset to factory settings
In case of unknown settings or use in a new application, it is recommended to reset the
FTR16 to its factory settings beforehand.
Factory settings:
• Process windows: 50 %
• Switching delay off
Perform factory reset
Operating magnet on "Auto Span" → green LED flashes quickly
Continue to stop operating magnet (min. 20 s):
→ after 10 s, red LED flashes slowly (warning of resetting)
→ after 20 s red LED flashes quickly
Remove operating magnet → parameter 7.4.2 to 7.4.4 reset to factory setting

Function test
• Function test only possible with parameterization mode deactivated (→ 20)!
• If the operating magnet is held ≥ 30 s against the marking, the red LED flashes and the
device automatically returns to the current switching state.
Perform function test
Operating magnet on "Auto Span", "Process Window" or "Switch Delay" (min. 2 s)
→ all LEDs light up briefly
→ current switching state is inverted
→ function test is performed
Remove operating magnet → change to normal operation
