12V fuses
The Elektroblock is equipped with so called PolySwitch fuses.
In case of failure, eg overload, such fuses break the relevant circuit, thus
protecting the device. PolySwitch fuses automatically reset themselves
after the fault has been removed. In case of failure the corresponding LED
lights and indicates the faulty circuit.
The electrical circuits are from left to right:
refrigerator
15 A
waste water heater/
water pump
10 A
light circuit 3
10 A
light circuit 2
10 A
light circuit 1
10 A
automatic step
15 A
* In some cases of short circuit, the main fuse of the starter or the living-area battery might blow instead
of the respective PolySwitch fuse. In this instance please disconnect the mains supply of the motor
home and take off all battery terminals of the positive poles. After that insert a new main fuse of the
same value. Before power is put back on, it is advisable to rectify the reason for the short circuit.
Please see section 5 'Electrical Installation' and in enclosure 'Schematic Diagram'.
* Troubleshooting hints when main fuses are blown (qualified personnel only):
•
A minimum of two main fuses are required; for the value refer to schematic diagram.
•
Undo the four screws at each corner of the front panel and pull out the device.
•
Disconnect all positive poles of each of the seven consumer circuits, label each one well.
•
Insert a new main fuse. Caution, danger of burning. Better disconnect the positive battery
terminal first. If the fuse blows again, the main circuit of the battery is at fault, otherwise:
•
Actuate 12V-switch on front panel of EBL 263-5: the green LED must light.
•
Connect one consumer circuit after the other by reconnecting the appropriate positive poles.
Wait for at least 10sec after each connection is made and observe the green LED.
•
The consumer circuit with the green LED going off is at fault.
•
Disconnect the appropriate positive pole of the faulty circuit and rubber-tape it against accidental
contact.
•
Insert a new main fuse and reconnect all other remaining consumer circuits.
•
All other circuits should function now. The faulty circuit should be repaired without delay.
CAUTION !
Danger of burning. Change defective fuses only at zero-current.
3.3 Relay
Functions
main-switch relay
This relay is controlled by the push-button switch
12V
on front panel.
bistable
It switches all 12V load off, except the circuit 'automatic step'.
See section 3.1 'Controls and Indicators'.
battery cut-off relay
This relay separates the starter and living-area battery when the engine
is not running and if there is no voltage on terminal 'D+'.
Both batteries are connected in parallel and therefore simultaneously
charged while engine is running.
water pump relay
This relay activates the water pump and is controlled by the 'water pump'
switch on the front panel. In 'ON' position the 'water pump' output is active.
See section 3.1 'Controls and Indicators'
Battery drain of relay: 160mA in 'ON' position
