Operation and maintenance, Discfilter HSF2600 - 2,3 series with PFLC
4.2 Automatic settings
The control system for the HSF2600 series must always be equipped with a frequency converter
for the drive unit. This is factory calibrated if delivered from Hydrotech. To perform a soft start of
the drive motor, the frequency converter settings must be min. 5 sec “ramp up” and min. 3 sec
“ramp down”. The filter works with 50 Hz as standard.
If the filter is equipped with a Hydrotech standard control, the filter has three operating modes:
1. Automatic level control (AUTO mode).
2. Remote control (REMOTE mode).
3. Service mode (HAND mode).
Turn the mode selector to select the appropriate operating mode (see Figure 4.2, detail F).
