AEZ 801 / 802
Sensor link checking on TSX AEZ 802
At a Glance
Fault bit
This checking is available in the range 4-20 mA. In this range the fault is detected by the TSX AEZ 802 module when the intensity in the loop becomes less than 3.2 mA.
The sensor link fault is signaled by a status word bit for explicit exchange which can be used by the system.
Sensor link fault bit:
Bit name
%MWx.i.2:X0
Meaning (for Xj = 1)
Sensor link fault on channel i of module x
Note: The channels of a TSX AEZ 802 module which have not been hardwired should preferably be set between 0-20 mA. If this is not the case, a "sensor link" fault will be signaled by the module.
