4 Operation
Adhere to the
switch-on
sequence
The voltage supplies to the control electronics and to the power section must
be switched on simultaneously.
4.1 Display after switch-on of the device
Sequence When the voltage supply is switched on, the LED Power is continuously lit
green first and an hour glass appears on the display. Then, the master is syn-
chronised with the slave device and a rotary field detection is carried out. If all
devices are wired correctly, the controller displays the mains voltage.

4.1.1 Display and control elements
Use and to view current measured values such as currents, voltage
A
Under no circumstances may the voltage supply for the control
electronics be switched on before the load voltage! This is especially
important for operating transformer loads and resistive loads with a
large temperature coefficient (TC >> 1)!
Legend Remark Fig.

LED Power (green) is continuously lit when the voltage
supply is connected.
It flashes regularly when the display light is switched
off.
