12.10. Automatic switch-off and heating
DLoG MPC 6 models with DC voltage can optionally be equipped with either an
automatic shutdown module or an automatic shutdown and heating module.
If the heating option is implemented, the DLoG MPC 6 can be operated at temperatures
ranging from maximum -30 C to +50 C.
Modes of operation
If wired up accordingly, the DLoG MPC 6 conveniently switches off together with the
vehicle’s ignition. As disconnecting the power supply during operation can lead to data
loss, the operating system needs to be shut down normally using the appropriate
hardware and software installed on the system when the ignition is switched off.
The DLoG MPC 6 is connected to the vehicle with three supply cables . DC+ und DC- are
directly connected to the power supply of the vehicle, the connection is of course run
through fuses (see section
7.5.2 DC power pack ) Therefore make sure that the cables
are connected directly to the battery and not to high-interference supply lines (for
example, motor supply) or to supply lines already used by other consumers.
The supply voltage connected is then linked to the DLoG MPC 6’s ignition input via a
switch, for example, the key switch of the ignition (also with a fuse, see section
7.5.2
DC power pack ).
Heating is required if you want to operate the DLoG MPC 6 at ambient temperatures
below 0
°
C.
In the following two sections, the main functions of the automatic heating and shutdown
modules are described. For detailed information on the automatic shutdown and heating
modules – complete with pre-defined thresholds – refer to the program flowchart
diagrams (part 1 and 2) below.
Resources
The automatic switch-off/heating module requires the COM3 port for configuration. In
normal use the LPT1 port is used for communication.
