Threshold Clamping and Undervoltage Detection: To prevent the input circuit from entering an indeterminate state if the wetting voltage is accidentally lost or drops significantly, the system implements two important protection mechanisms:
Threshold Clamping: Even if the wetting voltage drops to zero, the input threshold is clamped to 13% of the nominal rated voltage. Wannan yana tabbatar da cewa duk abubuwan da aka shigar ana tilasta su nuna 'KASHE' a yayin da aka sami asarar wutar lantarki, wanda shine ƙira mara inganci.
Undervoltage Detection: If the wetting voltage drops below 40% of its nominal value, the I/O pack detects this condition and reports an 'Excitation Voltage not valid' diagnostic alarm to the control system, alerting maintenance personnel to check the power supply.
