1)
If fault Er 1 occurs when permeate production is in progress (high-
pressure pump negative pressure switch), the system causes a new
start in at the following time intervals:
5 ... 10 ... 20 ... 40 ... 80 ... 160 minutes.
If there is sufficient pressure available, permeate is produced until
level "a" is reached, and the error is self-acknowledging.
The symbol flashes on the display in the waiting time between
the start attempts
2)
Pressure switch: Switch-on pressure 1.8 bar
Switch-off pressure 3.0 bar
The hysteresis of the pressure switch can be adjusted in parallel with
the central screw of the switch.
