Description of the TV 902 Navigator
A thermistor sensor is mounted near the upper bearing to prevent
the pump from overheating. If the thermistor reading exceeds 60 °C
the pump fails and stops with Error Code = 1 (WIN 206). If the
thermistor reading is below 0 °C, the pump fails and stops with Error
Code = 0 (WIN 206). See Window Meanings pag. 79-80, for details.
The pump is balanced after assembly with a resid-ual vibration
amplitude less than 0.01 μm.
The pump can operate in any position and can be supported on the
high vacuum flange. The connection of the forevacuum on the side of
the pump is a KF 25 flange.
