KK2 Pro Dual Pump Controller
1.0 Safety information for installing and using the controller
1.1 Area of Application
KK2 dual controller is designed to control water pumps used in various
sewage, waste water and rainwater pump stations.
For activating pumps that run in an Ex-area, the following needs to be
considered: The control unit itself has to be mounted outside of the Ex-
area.
If the floating switch is mounted in the Ex-area, the relevant regulations
must be followed.
When connecting motor, the electronic and mechanical motor protection
switch must be set according to the standard range given below.
Three- phase AC 380V 4.5KW
Max.12A
Single-phase AC 220V 2.2 KW
Max. 12 A
1.2 Qualification of personnel
The personnel for installing, initiating, and maintaining the control unit
has to hold according qualifications for this work.
1.3 Safety information for the operator
The existing safety rules of local energy supply companies should be
followed. When opening the unit or when maintaining the pump the
power to the control unit needs to be completely shut off through an
external pre-fuse.
1.4 Hazards if safety information is neglected
Neglecting safety information will endanger people and product/ unit.
When neglecting safety information you are subject to lose any
entitlement to damages.

manufacturer’s liability for possible consequences.
1.7 Prohibited operations
The safety of operation of the delivered product can only be granted when
the product is used appropriately according to paragraph 1.1 of the
operating manual. The limiting values given in technical values have to be
adhered to in any case.
1.8 Transport and storage
The control unit needs to be stored and transported avoiding damage by
blows, crush, and temperatures outside the realm of -20℃to +60℃.

FS and pressure pipe connection
In the pressure mode, the level FSes at 3·4·5·6 positions are not required
to be connected.
The high level alarm FS is floating over other level sensor. When the high
level alarm FS touches, the pump will be started and an alarm will be
issued. High level FS and other level sensor will form a dual protection.
If one pump needs to be removed for repair, press the “0” manually to
turn off the failed pump; the other pump can run normally and
automatically according to the previous setting contents.

7.0 Air pipe connection
The standard configuration of the air pipe connection is 8/6mm hose joint.
When connecting air pipe, the controller shall be at the OFF state and the
air pipe shall be in the suspension non-pressure state in the entire process.
After connecting air pipe and the power supply is turned on, water can be
drained in a container! With the pressure mode available to control level,
drain the level below the air inlet each time to allow the air inlet in the
suspension state. It is recommended to enable the “Stop Delay”
function for this.
