Classification:
Category 3GD (Zone 2 for Gas and Zone 22 for Dust)
Thermal Classification:
Thermal classification of motor is 100 °C (T5) (100 °C = 212 °F) for maximum full-load operating
temperature at a maximum liquid temperature of 90 °C / 194 °F.
8.1.6 Immunity to Voltage Sags – Semi F47
Based on internally testing at Levitronix
®
the pump system PuraLev® 2000SU in its various configurations is able to
handle all the voltage sags defined in SEMI F47. Therefore the pump system full fills the requirements of the SEMI F47
standard. The nominal voltage range is 200 – 240 VAC ±10% for operation without performance reduction. Based on this
range the voltage sags specified in SEMI F47 have an influence on the maximum performance as following:
Specified voltage sag
Impact on the system
80% of Equipment Nominal
Voltage, duration 1000 ms
No impact on the system operation mode since supply voltage is above the
warning level. Slight power drop at high flow rate and speed is possible.
70% of Equipment Nominal
Voltage, duration 500 ms
No impact on the system operation mode since supply voltage is above the
warning level; slight power drop at high flow rate and speed is possible.
50% of Equipment Nominal
Voltage, duration 200 ms
The system reduces the speed to 4000 rpm for save operation since supply
voltage is below the warning level.
After the disappearing of the voltage drop, the system is returning to its full performance.
