New customer training centre in the factory
The course makes use of the centrepiece of the
new training centre – our practice Air Handling Unit
(
AHU).
The AHU supplies the training room and two small-
er side rooms. One of the side rooms is regulated by
a Belimo MP Bus VAV actuator. Temperature and CO
2
are measured in all rooms, in order to optimize the
efficiency of the unit which is driven by frequency
converters.
Some of the sensors are connected using EnOcean
radio technology so we can include this topic into
our trainings as well.
The AHU conditions the air using a built-in cooling
system, a heater and a rotary heat exchanger (see
image).
The whole Air Handling Unit is controlled by a
Saia® PCD3.M5560 which is installed in the local
control cabinet. A 15" Intel Atom S-Web Panel
equipped with an embedded Windows XP is inte-
grated for a comfortable visualization of the process
using the S-Web or Saia®Visi.Plus.
The consumed electrical energy is measured by
Saia® S-Bus energy counters and the heat consump-
tion is recorded using M-Bus heat meters.
Lighting control is realized via a Saia® PCDconnected
over KNX/EIB while the current meteorological data
is captured by the roof-mounted weather station
and read over Modbus.
At the end of the training the participants get
the possibility to program and finally do the
comissioning of this Air Handling Unit with PG5.
By doing so the participants are confronted with
most of the technologies they will encounter in
their future daily work.
The new training centre is part of the official training
program from 2012. The training schedule can be
