Metrohm 838 Advanced Sample Processor, Appendix
In order to simplify the use of Remote commands, particularly when
several devices are linked together with Metrohm cables, predefined bi-
nary patterns are available as command parameters for the commands
CTL and SCN for standard conditions. These are:
Function
waits for "ready" condition of 732/1
waits for the EOD impulse from 732/1
waits for the EOD impulse from 732/2
waits for active Remote line 2 set by 732/1 or 797
waits for active Remote line 4 set by 732/2
waits for active Remote line 2 and 4 set by 732/1 and 732/2
waits for active IC pump 709/1
waits for active IC pump 709/2
waits for active IC pumps 709/1 and 709/2 laufen
Function
initializes the Remote interface
initializes the Remote lines of 732 or 819
starts/stops the time program of 819/1
starts/Stopps the time program of 819/2
starts/stops IC pump 818/1
switches valve A of 820/1 to "Fill"
switches valve A of 820/1 to "Inject"
switches valve B of 820/1 to "Fill"
switches valve B of 820/1 to "Inject"
activates autozero of 819/1
starts the pump of a 833
Stopps the pump of a 833
advances a step of the suppressor module 833
starts or advancesdevice 1 (e. g. 797 VA Com-
putrace)
