Fig. 3: SCC 950 hand terminals
To distinguish between the two hand terminals, the rotary knob
(Fig. 3/

) is marked 1 or 2.
Hand terminal 1 controls process 1 and hand terminal 2 con-
trols process 2.
Function
The hand terminals are used to set the process parameters of the
two processes with which the SCC 950 vacuum pump system
controls the pressure.
Settings can be made on the hand terminal's touchscreen (
2
) or
with the rotary knob (
5
).
Hand terminal 1 can be removed from the bracket on the vacuum
pump system (see Chapter 5.1.1, page 13) and the vacuum pump
system can be operated wirelessly. This provides a convenient
way to operate the vacuum pump system when it is in a cabinet or
under a closed fume hood.
Hand terminal 2 can also be used for wireless operation of the
vacuum pump system. It is packed loosely along with the other
components and can, if required, be placed on the enclosed charg-
ing station.
If a hand terminal is in the bracket on the vacuum pump system
when it is switched on or on the charging station and this is con-
nected to the mains supply via the supplied power supply unit, the
hand terminal batteries are charged automatically. The batteries
will charge even if the hand terminal is switched off. Alternatively,
the batteries can be charged through the hand terminal's power
supply (see mains socket (
4
) on the hand terminal). This eliminates
the need for the vacuum pump system to be positioned where it is
accessible for the user.
