Sensor monitor status
A message appears in the
event section of the start
screen as soon as the
sensor monitor is
(de)activated. This is always
displayed after switching on
to inform the user if the
sensor monitor is active.
The sensor monitor takes
into account only those
sensors whose “Alarm
event” parameter is set to
“1”. Changes to sensors for which the alarm event is not activated
do not interrupt monitoring!
If a change is detected to one of the monitored sensors and the
monitor is active, the sensor monitoring is halted. The time and
date and GPS data (if available) at the time of the event are stored.
The status display and status printout based on this information
enable precise determination of when and possibly where the seal
was broken. Information is also given about how the deactivation
was triggered. This can be caused by the change in status of a
sensor with activated alarm message (“-Sensor-”) or manually by
the user (“-Manual-”, menu 4.8.1).
An EMIS with a GPS function, if used, detects the current GPS
coordinates using the connected GPS receiver. This data is made
available to the other system units via the CAN bus. If no GPS data
is available, the EMIS supplies the last valid GPS data received.
The user is shown whether the GPS coordinates displayed are
those received at the time of the (de)activation or the most recent
valid data. A “-C-” indicates that GPS data was available at the
time of the (de)activation, while an “-L-” indicates that no GPS data
was received at the time and this is the most recent valid GPS
position.
A monitoring ID is specified in addition to the time, date and GPS
coordinates. This is a consecutive number which increases by one
every time the sensor monitor is activated. It is stored in the non-
volatile MultiFlow memory and can be set to 0 in a device reset via
parameter 4.4.
