22 January 2019 Page 21 of 205
The whole measuring and control technology of the bioreactor is
integrated in the console of the basic unit. One operating unit with
touchscreen software can be used to control up to six bioreactors
(culture vessels) see also chapter „Operating Unit“. This means,
one basic unit serves as the master unit and can control up to five
more basic units, referred to as satellite units.
3.1.1 Main Switch
The main switch, a green rocker switch, is situated on top of the
console. It is labelled with POWER and it is illuminated as soon as
it is switched on.
3.1.2 Pumps
Corrective reagent and feed solutions are added via four peristaltic
pumps. The pumps are driven by stepper motors.
The drive shafts of the pumps are situated on the upper front side
of the console on the basic unit. Direction of rotation is clockwise
by default. Rocker switches for manual operation of the pumps are
provided above the drive shafts. They are labelled as follows (from
left to right):

Acid

Base

AF (Antifoam)

Feed
When the basic unit is switched on, pumps can be manually oper-
ated via the rocker switches:

Push and hold the rocker switch to the left:
The pump drive shaft turns counter clockwise

Push and hold the rocker switch to the right:
