S-Vent
Wiring example for the Helix fan with external leads of the motor overheating protection and a magnetic starter is shown in Fig. 3.
The terminals TW1, TW2 are the leads of the normally closed contact of the motor overheating protection.
This contact must be serial connected to the power circuit of the magnetic starter coil that starts the motor.
In case of the motor overheating the contact is opened and breaks power supply to the starter coil. This way the motor is stopped.
