electrical motor always off
2)

3)
AUTO:
- in LOCAL the electrical motor is always running
- in OFF the power of the electrical motor is switched off in 30 sec. It is switched on when the local selector is
moved to LOCAL or REMOTE
- in REMOTE the electrical motor switches off, if the variation of the position request signal is less than 0.5%
for 15 min. It is switched on if the position request signal changes or if the pressure switch contact opens
If the pressure switch is still open after 10 min. from the start of the motor pump, an alarm is generated
