Pressure Determination
Pressure at the inlet flange of a VacIon pump is proportional to the
current drawn by the pump.
To determine the pressure of the inlet flange of the VacIon pump,
determine the pump current displayed on the front panel or read the
recorder output (especially for current lower than 1 mA), and find
the corresponding pressure value from the current vs pressure curve
of the relevant VacIon pump.
Power Failure
In the event of a power failure (momentary or long period) the
controller is switched off. When power is restored, the controller will
automatically restart.
Remote Control Mode Operation
It is possible to remotely switch onb and off the high voltage using a
permanent contact connected to pins 3 and 7 of J001 accessory
connector with the mains power ON/OFF switch to ON.
