5.3 ACCUMULATOR
5.3.1 GENERAL DESCRIPTION
Accumulator block is used for continuous accumulation of analog input signals or for preset counter purpose.
■
OPERATION
• Counter is automatically reset when the accumulated value reaches 10000 counts.
• Fractions exceeding 10000 counts are added after the counter is reset.
• When the counter reaches the preset value, the ‘preset value reached’ output Y1 is turned on. The Y1 is not reset automati
-
cally after the count has reached 10000, until the reset SW S1 is turned on.
• Turn on the interrupt SW S2 in order to halt counting.
• Accumulated value output is provided at Q0.
■
COUNTER RATE
Counter rate K represents the accumulated output value per time unit (second, minute, hour or day) provided when the input
is fixed at 100%.
For example, in order to have 150 counts per hour with the range 0...150 m
3
/h (1 count per 1 m
3
), set the K (ITEM 13) to
150 and the time unit (ITEM 14) to ‘2’ (hour). In order to have 1500 counts per hour (1 count per 0.1 m
3
), set the K to 1500.
