EDR MANUAL
Mode of operation
The Leab EDR is an electronically controlled
relay for charging two or more batteries. The
EDR is installed between the primary and the
secondary battery. The relay is open until the
primary battery reaches the correct voltage. It
then closes and both batteries are charged until
full. When consuming energy the battery voltage
will sink. The relay then opens and continued
consumption will only affect the primary battery
leaving the secondary battery next to fully char-
ged. The EDR unit has a built in timer that
causes the yellow LED to light up a few seconds
after the primary battery reaches correct vol-
tage and goes out a few seconds after charging
stops.
Installation
Install the EDR preferably vertical with the
cable connectors down. Use maximum 1 m long
cables to the primary battery.Use cables with
minimum 10 mm
2
area.
Electrical connection
Detach the connectors from the positive po-
les on both batteries.Connect the EDR accor-
ding to picture no 1. Reconnect to the positive
poles.
Test of installation when connected acc. to
picture no 2 :
* Turn on lamp connected to secondary battery.
* Detach connection from positive pole on se-
condary battery. The lamp should go off.
* Start and rev up engine.After a while the lamp
should light up again together with the yellow
LED.
*
Note! An alternator normally gives 14(28)V.
The EDR needs minimum 13,5(27)V to work
also under load. Check voltage on primary
battery poles.
* Stop engine and reconnect positive pole again.
