Use Of S4 And S5 Switch; Use Of Cv Jumper - gefran SM32 Manuel D'instruction

3.5. Use of S4 and S5 switch

The S4 and S5 dip switches are used to select the AC mains frequency.
AC Mains frequency
50 Hz (Default)
60 Hz

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.
