Engineering

Conduct the electrical connections in accordance with local regulations on electrical

installations as well as the section Connection diagrams [➙ 26].

NOTE

Using a safety limiter

Failure to comply with applicable regulations for cable insulation may result in the

suspension of the safety limiter function.

●

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.

●

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].

Smart Infrastructure

Compliance with all applicable regulations for cable insulation must be ensured by the

plant operator.

WARNING

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.
