Toshiba GR200 Series Instruction Manual page 1078

As the threshold voltage is expressed with Table 5.4-5, the user should set High or Low to
match to the voltage value to input to binary inputs. Table 5.4-6 shows the recommended
settings.
This matter means that the user should also set a threshold voltage at the power supply unit
to determine the degree of the power failure (see
module
).
