• Display: XXX – YYY
• Setting ranges: XXX value = 0 – 150% of Q
100%
YYY value = 0 – 150% of Q
100%
hysteresis ≥ 1% (= difference between XXX and YYY values)
• Switching behaviour (NO/NC contact) and hysteresis are adjustable.
NC contact XXX value > YYY value
NC contact XXX value < YYY value
Switch closes when flow exceeds XXX value Switch opens when flow exceeds YYY value
Example: XXX = 55% Example: XXX = 45%
YYY = 45% YYY = 55%
hysteresis = 10% hysteresis = 10%
Please note:
if two status outputs (e.g. D1 and D2) are activated
it is possible to have e.g. min. and max. values signalled.
