4.5.1 Power supply
LOTUS has a standard cable with CE-connector. For the power supply a fail-saved humid room damp proved
electric socket is required.
Notice:
•
The electric socket has to be placed nearby LOTUS for easy disconnection in case of emer-
gency stop or maintenance.
•
The electric socket must be placed free for easy access from all sides.
•
An overload protection for the power supply is stringent required!
4.5.2 Types of Control
Three different types of control are selectable:
•
Proportional to the flow, controlled by a pulse frequency input:
- e.g. by a contact water meter with Reed-contact (type
„CTFI“ ),
- a contact water meter with open collector or Hall-sensor,
-
or a magnetic flow meter (IDM).
•
Analog with a current signal (4 … 20 mA),
-
from a magnetic flow meter (IDM),
-
or a external chlorine dioxide measuring system (in Germany prohibited)
•
Level-controlled filling of a batch tank
Depending to the required control the LOTUS-controller has to be configured and an option has to be ordered.
