Function of the external powersupply :
In the separate power supply units the
operating voltages
are
generated
from the
AC power
network voltage.
The transformers provide
8 separate voltage
s that are rectified and buffered.
The standby trafo is providing the voltages for the input and control and is working all the time.
All the voltages can be
controlled
with
12 Leds
in front of the main PCB board in the PSU.
The two yellow an blue
Leds
in the
middle
show that the
Emitter
has given the
signal
,
the Leds left and right that the voltages are present.
In Off and Standby two green
Control
and two red Leds
Input
are shining.
After switching ON in
Energy mode
the yellow led
Energy ON
in the middle
shows that the Emitter main unit has switched ON the PSU, then the two relays in the middle
RE3, RE4 are switching and then the 2 yellow
EGY
and two green
Driver
Leds are shining.
After switching in F
ull power mode
a blue Led
Power ON
in the middle is shining,
then the 4 outer relays RE1,2,5,6 are switching ON and then two blue Leds
Power
will shine,
and the green
Driver
Leds will become brighter.
