Function
The hand terminal is used to set process parameters with which
the vacuum pump system SC 950 will control pressure.
Settings can be made on the hand terminal's touchscreen ( 2 ) and
with the rotary knob ( 5 ).
To operate the vacuum pump system remotely, remove the hand
terminal from the holder (see chapter 5.1.1, page 13) on the
vacuum pump system. This provides a convenient way to operate
the vacuum pump system when it is in a cabinet or under a closed
fume hood.
Whenever the hand terminal is located in the holder while the
vacuum pump system is turned on, the batteries in the hand
terminal will charge automatically. This happens even when hand
terminal is switched off. Alternatively, the batteries can be charged
through the hand terminal's power supply (see DC input (
4 )). As a
result, it is not necessary to place the vacuum pump system where
it is easily accessible for the user.
The power supply also makes it possible to supply the hand termi-
nal with electrical power directly from a mains connection.
An acoustic alarm sounds on the hand terminal when the battery
charge levels are low.
