IFM does not always package a physical manual. The primary source is their website or global distributor portals.
Reversing L+ and L– will permanently damage the electronics. Always use a fused power supply (≤ 500 mA). ifm flow switch sh0500 manual
SH0500 indicates flow (output ON) even when pump is off. Manual solution: Check hysteresis. If flow decays slowly (e.g., gravity drain), set hysteresis to 30 cm/s. Fix: Change HY. from 10 → 30 cm/s. Reset point becomes S.P. – HY = 20 cm/s off delay. IFM does not always package a physical manual
A: Press and hold both buttons simultaneously for 10 seconds until the display shows rES . Release. Confirmed by a triple flash. ifm flow switch sh0500 manual
