IP68
According to AUMA definition, enclosure protection IP68 meets the following requirements:
●
Depth of water: maximum 8 m head of water
●
Duration of continuous immersion in water: Max. 96 hours
●
Up to 10 operations during continuous immersion
●
Modulating duty is not possible during continuous immersion
Enclosure protection according
to EN 60529
Pollution degree 4 (when closed) according to IEC 61800-5-1
Pollution degree
2 g, from 10 to 200 Hz
Resistant to vibration during start-up or for failures of the plant. However, a fatigue strength
may not be derived from this.
Vibration resistance according
to IEC 60068-2-6
Environmental categories D, G, EMC2
GL approval
Suitable for use in areas with high salinity, almost permanent con-
densation, and high pollution.
KS:
Standard:
Corrosion protection
Suitable for use in areas with extremely high salinity, permanent
condensation, and high pollution.
KX:
Option:
Standard: Two-component iron-mica combination
Finish coating
AUMA silver-grey (similar to RAL 7037)
Standard:
Colour
Available colours on request
Option:
20,000 operating cycles OPEN - CLOSE - OPEN
An operating cycle is based on an operation from CLOSED to OPEN and
back to CLOSED
Open-close duty:
Lifetime
5 million modulating steps
The lifetime depends on the load and the number of starts. A high starting
frequency will rarely improve the modulating accuracy. To reach the longest
possible maintenance and fault-free operating time, the number of starts
per hour chosen should be as low as permissible for the process.
Modulating duty:
