1). The proximity switch give pulse to counter everytime the metal on the roller is sensed.
2). Length of Material ( in meter ) for one revolution = 3.14 X Diameter (mm)
3). Total length = { 3.14 X Diameter (mm) X Number of Revolutions } / 1000
4). Total Meters/Minute = { 3.14 X Diameter (mm) X RPM } / 1000
Note
1). When pulse comes from sensor, upper display indicates increment in ‘Total Length’ in
Meter & Lower Display indicates ‘Speed’ in Meter/Min.
2). For Manual Mode, set time = 00.0 sec & For Auto Reset Mode,
set time = 00.1 to 99.9 sec.
3). In RUN mode, if we press key then upper display shows Batch Count.
4). When Total Length = Set Length, relay-1 energise. Relay-1 remains ON for
Auto Reset Time.Relay turns off after completion of time. If time is set at 00.0 sec.
then relay remains ON until key is pressed.
5). If there is a power failure the last reading is stored in the memory and Counter starts
resume counting from the last stored value, when instument is turned ON.
6). To restart Totalizing or to Reset press key. Upper display will show 00000.0 and the
counting will restart.
