"Sleep" function/"Wake-up" functionThis function is used to stop the variable pump when there is zero flow (auxiliary pump stopped). In this case, if the frequency of the variable
pump is lower than the "sleep" threshold (LSP + SLE), a time delay (tLS) is launched. If, after this time delay, the frequency remains lower
than threshold LSP + SLE, the variable pump then stops. The installation is in "sleep" mode.
To switch to "wake-up" mode, the pressure feedback must drop to below the "wake-up" threshold UPP. The variable pump is then started.
Quick start functionThe quick start function can be used to overcome problems linked to high rPG and rIG gains (instability on starting). The drive accelerates
until it reaches the quick start threshold SFS following a ramp ACC. Once the threshold has been reached, the PI regulator is activated.
