The setting range is shown in the following table.
Atmospheric pressure
balancing valve ON time
–(Warming up time or analysis cycle,
whichever shorter) to analysis cycle – 2 s
Atmospheric pressure
balancing valve OFF time
–(Warming up time or analysis cycle,
whichever shorter) to analysis cycle – 2 s
* Make sure to set the 2nd time after 1st time, 3rd time after 2nd time.
* Set ON time and OFF time for each cycle in pairs with an interval of 1 s or more.
 DO operation time
This time is set to inform the timing of analysis completion by contact output to the upper level
calculator, etc. Set the processing designation to “Timing” per DO number with “DO setting” and
set SYS number and SYS method number. ON time and OFF time can be set three times per
cycle of SYS method, respectively, and whether to perform contact output to the upper level
calculator, etc. or not is also set. In this way, set the ON/OFF time of the DO timing signal, which
was set for the SYS in advance, with “SYS method.”
The setting range is shown in the following table.
DO ON time 0 to Analysis cycle – 2 s
DO OFF time 0 to Analysis cycle – 2 s
* Make sure to set the 2nd time after 1st time, 3rd time after 2nd time.
* Set ON time and OFF time for each cycle in pairs with an interval of 1 s or more.
Figure 1.37 GCM method and SYS method setting example 1
SYS1 and SYS2 analysis cycle are the same as GCM main cycle
Figure 1.38 GCM method and SYS method setting example 2
SYS1 analysis cycle is the same as GCM main cycle, and SYS2 analysis cycle is 1/2 of GCM main
cycle
