3.6. Use of CV jumper

(See the ML signal function)
With "CV" jumper mounted (ON), the signal available on the terminal 36 will be
LOW with AC mains voltage lower than the undervoltage threshold (see figure 3).
It will be HIGH, with AC mains voltage higher than the undervoltage threshold.
With "CV" jumper open (OFF), the signal on the terminal 36 will indicate, with an
impulse of about 150ms, (low level signal) that the power supply voltage has had
a transition at a level lower than the undervoltage threshold.
