MODE Three pushbutton control of functions are available
in the Auto Mode - Start, Vent and Standby
The Start function activates the pumpdown
sequence which monitors chamber and foreline thermocouple inputs
to ensure correct crossover and to provide pump protection
The Vent function activates the vent
sequence which includes triggering the ion gauge and closing
the vent valve on reaching atmosphere
