D Battery Monitoring Connector
Connection for temperature sensor for battery temperature and

connection
(middle point of the two batteries).
E Signal Connector
For details see chapter “Sig
n
al Outputs” and “
Inhibit-input
”
The 8-pole plug connector and the 2-pole push-in terminal comprise the replace battery, ready,
buffering and battery low pre-warning relay contacts..
The 8-pole plug connector also comprises the inhibit signal input.
F Red Error LED
For details see
figure “Flashing pattern for red Error LED”
This LED indicates that charging or buffering is not possible. The flashing pattern reports check
wiring, battery fusses, too high/low voltage or too high/low temperatures.
G Yellow Diagnosis LED
For details see figure
“Flashing pattern for yellow
d
iagnoses LED”
This LED helps troubleshooting and the flashing pattern indicates output overloaded (current),
battery replacement required, expired buffer time due to buffer time selector or discharged
battery or activated inhibit-input.
H Green Status LED
For details se
e figure “Flashing pattern for green Status LED”
Each battery has its own status LED. Battery 1 represents the battery, which is electrically closer
to the (+) pole and battery 2, which is closer to the (-) pole. The flashing pattern of this LED
reports ready, charging or buffering.
I
Battery Size Selector
For details see chapter “Batteries and Battery Charging”
Six positions to select battery sizes to optimize the charging process, the battery quality tests and
protection features. Factory setting is 12Ah.
J
Buffer Time Limiter
Six positions to limits the maximum buffer time in a buffer event to save battery energy.
Selectable between 10s 30s, 60s, 3 minutes and 10 minutes. If no limitation is selected (infinite
period of time), the buffering will be ended by the deep discharge protection. Factory set:
infinite.
K Chassis Ground
Use a M4 ring-type terminal to connect the housing to ground, when required.
