6.4.2 Submenu Pulse Output
Example 1 A new pulse width is entered
Settings
Input
QmMax = 24 kg/min = 0.4 kg/s
totalizer unit kg
pulse factor = 100 pulses /kg
pulse width 10 ms
→ 0.4 kg/s
⋅
100 pulse/kg = 40 pulse/s → Frequency = 40 Hz
→ Period = 25 ms
→ maximum pulse width = Period /2 = 12.5 ms
→ Result: entered pulse width of 10 ms is acceptable
Example 2 A new pulse factor is entered
Settings
Input
QmMax = 6 kg/min = 0.1 kg/s = 100 g/s
totalizer unit g
pulse width 10 ms
pulse factor 60 pulses /g
→ 100 g/s
⋅
60 pulse/g = 6000 pulse/s → Frequency = 6000 Hz
The converter automatically reduces the pulse factor to 50 pulses/g which
corresponds to a period of 0.2 ms (5 kHz)
→ maximum pulse width = Period /2 = 0.1 ms
→ Result: The entered pulse factor and pulse width were both automatically
decreased
