Behaviour when switching the mains
The value loaded last is stored permanently when the supply voltage is switched off and reloaded
after the mains is switched on again.
• In order that the stored value is not immediately overwritten by the current input signal at wIn
after switching on the mains again, bLoad must be set to FALSE when the mains is switched on
again.
