Step Indicator
The powers they are belonging to are not yet informed
A step indicator made by symbols that can be easily realized by the user, is located on the upper
part of the screen of VARko-112-TFT. No matter which part of the user in, this panel is always
located on the top of the screen.

LCD screen is used in VARko-112-TFT to provide it to be more easier in use and be
intelligible. In case the keys are not pressed for a long time, the device switch to the screen saver
mode to extend the life of the display, and only the step indicator shown on the the top scrolls
down step by step from the top to the bottom of the screen. Thus, the condition of the steps can
be continued to be monitored. In case of pressing on any key, the main screen image appears
again.
■ The connections of the device should be made while the system is energy-free.
■ VARko-112-TFT should be connected as shown in the connection diagram.
■ Current transformer and voltage connection should be made according to Scheme.
■ The value of the selected current transformers should not be under the real load values but
should be X/5 amper. It is also advised to choose 0.5 class.
■ Connect the “C1,C2” common phase inputs to the same phase with FF type fuses seperately.
Select the fuses to be used according to the specified current value.
■ Do not energize the device without ensuring the connections checked by measurement
instruments.
