1.15.14.2 Zero Test

P1386 (KRICmin) 

In the zero test mode the integral is monitored when all input signals are completely switched off. An error is assumed if the integrator gradient of the "zero test pulse" exceeds a calibrated threshold. The corresponding KRICmin fault is set as soon as a calibrated number of consecutive fault assumptions is exceeded. The fault path is cleared when the same number of consecutive Zero test measurements are performed without detecting a fault.
