Hooking up KR4 and KR7 basic controllers
1. Power supply
Both the KR4 and KR7 models must be hooked up to a 230 V
power supply.
2. Hooking up the fault contact
In the normal operating conditions, S1 is connected with S3. In
case of a fault or when the device is voltage free, S2 is
connected with S3.
3. Motor connection
In order to avoid interference from the connecting wires to the
motor, it is necessary to install each of these separately in a
shielded cable. The KR4 and KR7 frequency inverter from
Klingenburg operate with an output voltage of 3 x 230 V. This
must be taken into account when wiring the terminal board on
the motor. Using standard motors 230/400 V they have to be
installed in delta connection.
4. External control signal inputs
Control signal connection
The KR can process the following signals:
Hook up the control signal to terminals 2 and 3.
For a control signal of 0 - 20 mA or 4 - 20 mA, the pins must
be jumped as illustrated below.
For a control signal of 0 - 10 V, the pins must be jumped as
illustrated below.
5. Connecting the rotation monitor
The rotation sensor must be hooked up to terminals 4, 5 and 6.
6. Controller release (Enable)
The controller release is driven over terminals 7 and 8 on the
control terminal strip. The contact used to connect the
controller release must be voltage free.
7. Thermal protection relay - motor
The thermal protection relay must be connected using shielded
wire in order to protect the motor from excessive overheating
when running at low speeds. The warranty is voided if the
thermal protection relay for the motor is not connected.
