Switch-on conditions / additions to clearing malfunctions
Remark
Switch-on conditions have been determined for the PowerCEMS100 analysis system which
serve to ensure safety and function monitoring of certain analysis components. These are
realized by using signal status queries.
Depending on the version of the analysis system, status signal queries run either via:
●
A signal series connection
or
●
I/O interface modules of the BCU
Queried status parameters to fulfill the switch-on conditions
●
Gas sampling probe (option) - temperature setpoint value monitoring.
– Setpoint value monitoring through integrated low temperature alarm contact.
●
Heated sample gas line (option) - heating function monitoring
– Monitoring via temperature controller.
●
NO
x
converter (option) - function monitoring
– Query of setpoint value operating temperature.
●
Sample gas cooler - function monitoring
– Query of setpoint value operating temperature.
●
Level sensor in condensate collection container - filling level monitor
– Query of maximum filling level. In case of maximum filling level, the switch-on
condition is not enabled.
●
Gas analyzers - failure monitoring, monitoring / query of self-diagnostic functions
– For internal monitoring parameters such as:
> Temperature
> Flow rate
> Humidity
appropriate messages are sent via CAN bus to the BCU.
●
Sample gas pump - monitoring the pump function
– Monitoring the pump function is controlled via the gas analyzer.
Note
▸
Configured switch-on conditions may not be deactivated or ignored.
▸
Deactivation or failure to observe the switch-on conditions leads to serious
damage on the analysis system.
▸
Refer to the Technical System Documentation for information on the system-
specific switch-on conditions.
▸
A status signal is enabled confirming fulfillment of the switch-on conditions
when setpoint values are maintained.
