Application FIG 5-5:
The air conditioning system of a department store is to be controlled according to
the number of persons present. The fans must circulate an amount of air that
depends on the number of people (e.g. data provided by a person counter).

Stop!
If the mechanical resonance points are approached, the mechanics may be
damaged.
1. Remain C625 to C628 in factory setting.
2. Detect mechanical resonances (if not already known).
3. Detect the bandwidth of the mechanical resonances.
4. Set C625 to C628 according to the data available.
Note!
Terminal E3 must always be at L level (PAR2: normal operation; PAR1: QSP).
