DC voltage monitoring

Threshold voltage for detection/non-detection of power error

DC voltage is monitored in the PWS and a power supply failure can be outputted for the

Automatic supervision function. The user should set the failure level of the PWS. See

Automatic supervision function

Table 4.5-5 shows the threshold voltages for detection/non-detection of the power error at the

level high and low. This also shows how to set them with a shunt connector.
