Connect display unit type “VA3K01” to flow sensor type “VMM”
and programming
Example flow sensor VMM32D1110KAMA20 with the
data:
• Measuring range: 0–10 m³/h
• Pulse rate: 1000 pulses/m³
• Current output: 4–20 mA
• Frequency output: 0–1 kHz
Terminal assignment and connection of VA3K01 and VMM:
Terminal assignment VMM:
4 = pulse output (passive) –
5 = pulse output (passive) +
6 = status output (passive) –
7 = status output (passive) +
8 = current output (active) –
9 = current output (active) +
Terminal assignment VA3K01:
1 = INP A (signal input A)
8 = 24V DC (sensor supply voltage)
9 = GND (sensor supply voltage)
Supply voltage VA3K01:
(see operating manual VA3K01, p. 21)
16 = 10…30 VDC (supply voltage)
17 = GND (supply voltage)
