Modules that trigger an alarm

Trimble 4D Control Server features the following modules that may trigger an alarm:

Module	Possible alarm conditions
Central Controller	Hardware key disconnected Software update available
Accelerometer Manager	Data does not arrive for a least a specified period
Data Collector	Integrity check failed Target not found Time limit exceeded Compensator out of range Connection failed Connection lost Total station is locked
Data Logger	No data Sensor failure
Data Receiver	Integrity check failed Target not found

Device Manager	Multiple stations missing
Ephemeris Manager	Expected ultra rapid orbits missing
FTP Mirror	FTP job failed
GNSS Receiver	Backup connection lost Incoming connection lost No data from instrument Source of power supply changed Switched to backup connection Temperature exceeds threshold Tilt angle exceeds threshold Voltage exceeds threshold
Integrated Survey Engine	No temperature data available Point not computed
Integrity Monitor	Adjustment not computed Alert for displacement* Disarm alarm for all displacement* directions Warning for displacement* *Displacement directions are: easting, northing, h, 2D, 3D, slope distance
NMEA Receiver	Fix lost No data from NMEA Receiver
Post Processing Engine	No fixed solution for baseline
Router	Backup connection lost Incoming connection lost Outgoing connection lost Switched to backup connection
RTK Engine	RTK fix lost
RTX Engine	No RTX solution
Terrestrial Engine PP	Incomplete measurement Point not computed Target missing
Terrestrial Engine RT	No temperature data available Point not computed

Note – You can set up alarms for individual GNSS Receiver modules as well as for a failure of multiple receivers. In the latter case, you set up an alarm for the Device Manager module and define the minimum number of stations that have to fail before an alarm is triggered using the General Settings dialog of the Device Manager module.
