Connection Control
After, the connections of the device are completed, you can check the connection you established by
using the test functionality.
The device switches into the connection test mode if the BACK button is pushed for 3 seconds. In this
mode, at least 20% of the normal voltage and 10% of the nominal current must be applied on the
measurement inputs of the device and the angle difference between the voltage and current inputs
should be lower than 30 degrees. In other words, this control can be provided for the loads over 0.87
Cos Fi value.
In this mode, the device can control the connections and if there is any fault through the current flow
directions, it can correct such faults by software or leave it to be handled manually by the operator.
If, there is any connection fault between voltage inputs, this fault can only be corrected by changing the
cable connection points.
If, you experience the fault number 12, please make sure that all connections are established and the
aforementioned minimum current and voltage values are applied on the device.
The possible connection faults as a result of the connection test process and the codes displayed on the
device screen for these faults are indicated in the following table:
Test Fault Code
