Manual Extract Single Faults On Outputs
General
Faults related to ON/OFF outputs are detected by comparing the desired output state with the actual output state (during feedback). This implies that if an output is intended to be OFF it is not possible to detect shorts to ground. If, on the other hand, the output is intended to be ON, open circuit faults or shorts to battery plus cannot be detected.
This limits the controller’s ability to permanently detect faults on these outputs. The built-in output self test monitor overcomes this problem but requires vehicle standstill to operate.
The TCT16 cannot distinguish between open load or forced to plus conditions. An open circuit condition on these outputs is therefore interpreted as a “forced to plus” condition.
If any ON/OFF output is shorted to ground, the fault is shown on the display but no further action is taken. The background for this is that a short on an output always results in switching the load off. This either forces Neutral or a shift to a higher range.
