Ambient temperature
SAI:
– 25 °C to + 80 °C
SARI:
– 25 °C to + 60 °C
under DBE conditions for a short time up to 172 °C
Vibration resistance
after OBE (Operating Basis Earthquake):
2 – 35 Hz, acceleration 3 g
after SSE (Safe Shutdown Earthquake):
2 – 32 Hz, acceleration 4,5 g
Lifetime according to IEEE 382
SAI:
2,000 operating cycles (OPEN - CLOSE - OPEN) according to IEEE 382 - 1978)
SARI
3)
:
at least 100,000 operations according to IEEE 283 - 1978
1) Based on 20 °C ambient temperature and at an average load with running torque according to Technical data SAI/SARI
2) Not part of the qualification according to IEEE 382
3) 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 operation time, the number of starts per hour chosen should be as low as permissible for the process
