7.6.1.10 Shunt Overvoltage Threshold (SOVL) Register (Address = Ch) [reset = 7FFFh]

If negative values are entered in this register, then a shunt voltage measurement of 0 V will trip this alarm. When

using negative values for the shunt under and overvoltage thresholds be aware that the over voltage threshold

must be set to the larger (that is, less negative) of the two values. The SOVL register is shown in Table 7-14.
