The nominal torque of the motor must be equal or greater than the maximum setting of the torque switch.
Closing the valve: motor stops through torque switch. Limit switch on security.
Opening the valve: motor stops through limit switch. Torque switch on security.
Assembly of the motor
- Put the 4 bolts H
- Assembly the adaptor on the motor with the 4 CHC bolts
- Assembly the motor/adaptor on top of the operating stem of the valve.
- Tighten the bolts.
