The electronic motor current monitoring monitors the rated current of the connected
pump. Set rated current according to rating plate:
DIP ƒ
Set rated current via DIPs 1-5 on DIP switch 1.
ƒ
Minimum rated current: 1.5 A. All DIPs are in the "OFF" position.
ƒ
The current value is increased by the value of the respective DIP by activating the in-
dividual DIPs ("ON" position).
ƒ
Max. rated current: 12 A.
DIP
Current value
Example: required rated current 7.5 A
1.5 A + 2.0 A (DIP 3) + 4.0 A (DIP 5) = 7.5 A
The connected pumps are switched on via DIPs 6 and 7 on DIP switch 2:
DIP ƒ
The factory setting for both DIPs is "OFF". Level control dependent activation of the
pumps is not possible.
ƒ
Switch on pump 1: Set DIP 6 to "ON".
ƒ
Switch on pump 2: Set DIP 7 to "ON".
NOTICE
Do not apply external voltage!
An external voltage which is applied destroys the component.
