CAN- Bus- Systems

The CAN-Bus is a type of network, which
is used mainly in the automotive engineering
It combines different control units, called
nodes, to exchange informations.
The nodes are installed in the near of the
sensors and actors.
The BADER air conditioning systems are
built according to this principle.

Control panels

Depending on type and construction the
units are used to serve the climate controller  (see control devices )
or for autonomous climate control in vehicles
 e.g. driver cabines or minibusses.

Control units

The devices can be used in different modes.
- "stand alone", all values are preseted, no
   handling required
- in combination with a control panel,
  the communications works by RS232
- or with external switches and potentiometres,
   e.g. a control console.

Thermostats

The BADER thermostats are used for
carrying out simple control functions,
e.g. the climatisation of refrigerated trucks or containers.
There are different control functions:
two-level controller, three-level controller, four-level controller.

Automotive relays

The BADER relays are devided in the following
functions:
1. time relays with different time responses,  like
    impuls extension, switch- off delay, 
    switch- on delay
2. voltage control relays, for monitoring
    the on board voltage  for switched loads
3. Starter safeguard lock relays, for locking
    the start operation during running machines

Voltage converter

The voltage converter are used for converting
the 24 V on board voltage to 230 VAC voltage
They vary in different power types
The outputs are protected against overload and shortcut.

Sensors

The BADER temperature sensors have different
constructions depending of the application
- indoor temperature, roof channel
  temperature,
  convector temperature, blow out temperature.
- outdoor temperature, motor temperature,
  evaporator temperature.
