Description of Leds shining in operation
In
OFF
in the main unit a red Led near the 8 pole Dip and the green Led
+11V
should shine.
Without battery unit also the 4 red Leds from
input
should light up.
In the
power supply units
two red Leds for
input
and two green Leds for
Control
are shining
In
Standby
the two Leds for
+11V
and
-11V
should shine, the Leds from the input selector, the 4
red ones from
input
and the 4 green ones near the Offset and Overload Leds.
In
ON
position all operation voltages should be present.
In the
main unit
the operation voltage is shown with 4 yellow Leds for the
output
voltage,
4 green ones for
Driver
and 4 red ones for
input
. Check the positions on the plan in section 6.2

Checking fuses in the power supply units
When the Emitter is not working please check at first if the two red Leds for
input
and two
green Leds for
Control
are shining in the external power supplies. If not please check if the AC
cord is plugged in properly at the PSU and the AC wall plug. If yes - please unplug the AC cord,
open the PSU units and check the fuses inside. There are two fuses-
The main fuse - the big one left the PCB board (230V = 10 A slow, 115V = 16 A slow)
The small fuse in a black tube right on the Pcb Board is a 0,5 A at 230V and 1 A at 115V
When the Leds in the power supply units are shining, please check if the heavy silver connection
cables from the main unit are connected properly to the power supply units.
5.5
External battery power supply
After switching on the main unit the blue
Batt ON
bar should light up in the front plate of the
battery unit, and the Emitter main unit is supplied out of the battery.
If that does not occur, and the yellow
Charge
is lighting up instead the batteries are empty and
should be charged. After
recharging
the battery unit switches
automatically back
into battery
mode. If the charge led is not shining please check if the AC cord is plugged in properly.
Also check the fuse that can be found in the little drawer in the connector for the AC plug at the
backside of the battery unit. Replace the fuse, when necessary with a 0,5A/230V and 1A/115V.
