-
3.3 Ω ÷ 13 kΩ – quiescent mode (detection);
-
over 30 kΩ – fault mode (line break).
Lines are supplied with 18 V measuring voltage. An active mode of a monitoring line is triggered by
loading it with 1 kΩ characteristic resistance. In the quiescent mode, each monitoring line should be
loaded with a 10 kΩ end-of-line resistor connected to the end of this line.
Each of the 11 inputs may be programmed to perform the fK functions defined in Table 9.2.
