4.2 ABC Interval
The ABC Interval is the time between the automatic initiation of ABC Cycles. In typical
applications, an interval of 24 hours is recommended and set at the factory. However, in cases
where ambient conditions are more variable, or the sample gas is higher in contaminants, a
shorter interval may be required.
The times listed below are approximate.
The interval is adjustable in 4 hour increments from 4 to 28 hours.
Switch positions S1-6, -7, and -8 represent a three bit binary code with a weight of 4 hrs. per
unit.
To set the interval, set S1-6, S1-7, and S1-8 according to the binary number from Table 4.2
below. The factory default is 24 hrs.
NOTE:
‘CLOSED’ is a zero and ‘OPEN’ is a one.
