1 ≤ 220 Ω Short circuit
> 220 Ω to 8 kΩ Active [2]
> 8 kΩ to 10 kΩ Fault [3]
> 10 kΩ to 20 kΩ Standby
> 20 kΩ Open circuit

[1] Values between each state may vary, depending on tolerance.
[2] For EN 54- 13 compliance, the active impedance should be in the range of 220 Ω to 3.9 kΩ.
[3] High impedance fault.
[4] For the open circuit supervision of the fault warning output with the input, a 2010-FS EOL
board must be installed. See “Connecting the fault warning output” on page 17.
