*Operating principle of temperature monitoring
- Temperature limiter - monitoring of one temperature level
- When the threshold is reached, the motor switches off. When the motor has cooled down, the motor can restart automatically.
- Automatic restart depends on local necessities (e.g. explosive atmosphere, local regulations, etc.) It can be necessary to switch off the motor with a reactivation lock. Obey the local necessities.
- Temperature control - monitoring of two temperature levels
- When the lower threshold is reached, the motor switches off. When the motor has cooled down, the motor restarts automatically.
- When the higher threshold is reached, the motor switches off with a reactivation lock. Automatic restart is not permitted.
