Functional Description (continued)
Switching off the power supply
If the accumulator voltage drops below 10.5V during
accumulator operation, the power supply to the control panel
and the external users is switched off (switch-off relay).
This avoids unforeseeable reactions from the control panel
on the one hand, and protects the accumulator from deep
discharging on the other.
A "!U_bat<" signal is given before switch off (See below for
description).
Collective faults:
The messages are transmitted via the outputs
- "Fault" (ST100/3), HIGH active and
- "Fault" (ST100/2), LOW active.
The following fault causes are possible:
Mains / ext. user / charger controller defective /
accum. defective or missing / SE input
The type of fault can be determined by the LEDs on the power
supply PCB.
With the DIP switch S100 certain fault causes can be switched
to the collective fault output (see Chapter 7 "Connection Dia-
gram").
Fault U_ext. (ST100/7), output, LOW active.
This output is active when there is a fault in the user outputs.
Fault SE (ST100/1), input, LOW active.
For connecting "Fault" outputs of additional emergency po-
wer supplies (cascading).
Mains (ST100/6), output, HIGH active.
This output is active during power on.
!U_bat<: (ST100/8), output, LOW active.
Switch-off warning
This output warns of the impending switch-off of the power
supply.
The output is set when the accum. voltage drops below 10.8
V. A corresponding message can be transmitted e.g. via an
AWUG.
U_bat <10.5 V (ST104/2), output, HIGH active.
This output is transmitted when the power supply (U_bat
<10.5 V) is switched off.
TEST (ST104/1), input, LOW active.
This input allows a function test of the output U_bat <10.5 V
(ST104/2) by applying a 0 V potential. LD3 must light up.
Attention
It only is permitted to switch the input "Test" to the
0 V potential.
Do not apply a HIGH potential.
RESET key
For the initial start-up procedure, the mains voltage must
be available so that the switch-off relay is energized and
the voltage is connected to the power supply output.
The reset key is necessary, when the power supply unit requi-
res operating without mains (e.g. for test purposes).
The reset key is used for energizing the switch-off relay.
Mounting and Connection Instructions Mains/charger unit 12 V DC / 130 Ah
5. Set charge terminating voltage
1. The power supply must have reached operating temper-
ature.
For this purpose it must be operated for at least two hours
at rated load and with closed housing.
2. Connect a charged accumulator.
A not completely charged accumulator leads to a miss-
alignment.
3. Adjust the voltage at the accumulator terminals using the
potentiometer PO100 according to the ambient temperature
at the accumulator as per the following table.
Please take note of the type of accumulator.
1. After measuring the exact temperature and
2. When the voltage deviates >200 mV from the set value as
per following table.
Sonnenschein accum.
6. External NTC thermistor resistor
When using an external NTC thermistor resistor, the wire jumper
DB102 must be debridged.
The external NTC should be fixed to the accumulator in a suit-
able manner (e.g. with double-sided adhesive tape) and con-
nected by soldering to the bore holes.
ATTENTION:
Only alter the charge terminating voltage:

Important information!
In some cases it may happen, that the battery voltage of
new 65 Ah batteries is higher than the charge termina-
ting voltage.
LD5 "Charger controller defective" lights.
In this case we recommend, to operate the panel for
some time on battery power until the battery voltage has
been equalized.
Item no. 010693
Note: Basically, we recommend using an external
NTC thermistor resistor.
If the accumulator is not in the close vicinity of the
NTC100, an external NTC thermistor resistor must be
used.
For installation in compliance with VdS, an external
NTC thermistor resistor must always be used!
