• PSG gauges: They consist of one vacuum pressure sensor.
• PCG gauges with or without ATM: They consist of two vacuum pressure
sensors. The characteristic of this combi device is that only one vacuum
pressure sensor outputs an actual pressure value at one time. The other sensor
is in overrange condition which means that the pressure is higher than the
measurement range of the sensor or underrange condition which means that
the pressure is lower than the measurement of the sensor. The 'Combination
Gauge Active Value' outputs the pressure value form the active measuring
sensor.
For each sensor module a default mapping is configured. The mapping for each
sensor module has the same contents. For a compact cyclic data frame
duplicated mappings can be deactivated.
Or to meet other requirements the TxPDO’s 1A01, 1A03 or 1A05 and the RxPDO
1601 are designated for user mapping. These PDO’s do not have default values
and can be set up by the PDO configuration.
