NOTE
Using a safety limiter
Failure to comply with applicable regulations for cable insulation may result in the
suspension of the safety limiter function.
● Compliance with all applicable regulations for cable insulation must be ensured by the
plant operator.
WARNING
Risk of injury and fire from hot device
parts
For media below 0 °C, the stem heater ASZ6.6 keeps the valve stem ice-free. In this case,
the actuator bracket and the valve stem must not be insulated in order to ensure air
circulation.
Touching heated parts without safety measures leads to burns.
● For safety reasons, the steam heater is operated with AC 24 V / 30 W.
● Recommendation: For media above 140 °C, the valve must be insulated.
Observe admissible temperatures, see Use [➙ 2] and Technical data [➙ 19].
If an auxiliary switch is used, its switching point should be indicated on the plant schematic.
Every actuator must be driven by a dedicated controller, see Connection diagrams [➙ 26].
