Presetting the HC8X
Danger of electrical shock!
Disconnect all poles of the power section from the supply voltage before opening the
case.
Remove the case cover and pull off the ground conductor.
Danger to life by electric current!
The supply voltage of the control electronics remains present when the operating mode is
set.
Do not touch live parts.
Operate slide switch only with a totally insulated tool.
When using the slide switch, make sure that the PC board is not damaged.
Basic Setting
Set the HC8X to the basic state:
1.
Switch off the supply voltage of the HC8X control electronics.
2.
Push the slide switch (see Fig. 1-4, page 1-17) to position "B".
3.
Switch on the supply voltage of the HC8X control electronics.
LED25 acknowledges with a single short blink.
4.
Push the slide switch to position "A" again.
After the successful transfer of the preset values to the EEPROM, the HC8X starts in the
"Norm" operating mode with the parameters in
