2 Transmitter JUMO CANtrans
2.2.1 Operation
(1) The analog signal from the pressure cell or the temperature sensor is dig-
itized.
(2) The pressure or temperature signal is digitally calibrated at the factory.
(3) The temperature signal is linearized.
(4) Undesirable signal fluctuations can be suppressed through the (adjust-
able) filter constant.
(5) The sensor monitoring facility continuously checks the correct perfor-
mance of the sensor signal and triggers high-priority emergency tele-
grams in the event of an error.
(6) The measurement can be scaled to any dimensional unit (or in % of
range).
(7) Fine calibration features an autozeroing function (with pressure sensors
only) and a freely adjustable shift of the characteristic (offset).
(8) The measurements are output with a freely selectable decimal place.
(9) Range monitoring features freely selectable upper and lower limits. The
result is output as a status byte together with the measurement value in
the PDO telegram.
(10) The drag pointer function stores the minimum and maximum pressure
measurements.
(11) Date and name of the last servicing action can be stored.
(12) An emergency telegram is triggered in the event of a sensor fault.
(13) The PDO telegram contains the 32-bit measurement and the 8-bit status.
The measurement that is output can be controlled by means of different
trigger conditions.
(14) Parameters can be set through SDO telegrams, and measurements and
status can be requested.
(15) The heartbeat signal or Node Guarding
1
can be used to additionally mon-
itor the transmitter functions.
(16) Measurement transmission can additionally be controlled by using the
Sync command.
(17) The NMT telegrams serve to control the operating status of the transmit-
ter.
(18) The CAN node ID and CAN baud rate is set via LSS or SDO, according to
choice.
1 Node Guarding is only available for transmitters with sensor.
