6.Function sequence and error status after the receipt of the 'SRES' or 'STBY' commands

1.The test bench control computer is sending the control command SRES (Reset) to the system unit or any single analyzer.

All running functions or procedures will be canceled. An initializing will start, that is analogous to the switching on of the system unit or the analyzer: CPU and memory check, regulating or controlling of required temperatures, igniting of the flame in a FID an so on. The operation mode of the system or analyzer is "stand-by" during the initializing, even if the device is not ready and error free. That means, the status STBY will be reported to the read command ASTZ. The test bench control computer can only realize with the read command ASTF (error status), if the device is ready for measurements. The device will be ready to measure, if the essential functions of the current measuring instruction will be error free.

Example:

The status of the system unit or analyzer is SXYZ. The test bench control computer sends SRES:

Test bench control computer sends SRES Kn System or analyzer will response SRES x

The system unit or the analyzer will cancel the status SXYZ. It will run a CPU and memory check and it will control the temperatures. If the temperatures are out of the allowed setpoint range, the device will regulate it. The FID will control the flame and will try to ignite it, if necessary, and so on. The test bench control computer will read the operation mode and the error status:

Test bench control computer sends ASTZ Kn

System or analyzer will response ASTZ 0 SMAN STBY

or

Test bench control computer sends ASTZ Kn

System or analyzer will response ASTZ x SMAN STBY

Test bench control computer sends ASTF Kn

System or analyzer will response ASTF x n

The error status byte will be zero and the system or the analyzer will be ready to measure, if all temperatures are in the allowed setpoint range, if the FID flame is burning etc.

If these parameters are not correct, the error status byte will be different from zero. The test bench control computer will read the operation mode and the error status as long as the system or the analyzer will be ready to measure. The test bench control computer will control the maximum time for this reading.
