Wire Fail Detection
If it is necessary to supervise the sensors/wires connected to the multi-inputs and
analog inputs, then it is possible to enable the wire break function for each input. If the
measured value on the input is outside the normal dynamic area of the input, it will be
detected as if the wire has made a short-circuit or a break. An alarm with a configurable
fail class will be activated.
Input
Wire Failure Area
Normal Range
Wire Failure Area
4-20 mA
< 3 mA
4-20 mA
> 21 mA
RMI Oil, type 1
< 1.0 ohm
-
> 195.0 ohm
RMI Oil, type 2
< 1.0 ohm
-
> 195.0 ohm
RMI Temp, type 1
< 4.0 ohm
-
> 488.0 ohm
RMI Temp, type 2
< 4.0 ohm
-
> 488.0 ohm
RMI Temp, type 3
< 0.6 ohm
-
> 97.0 ohm
RMI Fuel, type 1
< 0.6 ohm
-
> 97.0 ohm
RMI Fuel, type 2
< 1.0 ohm
-
> 195.0 ohm
RMI/VDO configurable
< lowest resistance
-
> highest resistance
Level switch
Only active if the switch is open
Principle
The illustration below shows that when the wire of the input breaks, the measured value
will drop to zero. Then the alarm will occur.
