Solar Charge Controller CML05-2, CML08-2, CML10-2, CML15-2, CML20
User Manual English, Page 2
Low Voltage Disconnect Function (LVD)
The controller has 2 different modes to protect the battery from being deeply
discharged:
1. State of charge controlled: Disconnect at 11.4 V (at nominal load current) up to
11.9 V (at no load current). Normal operation mode for good battery protection.
2. Voltage controlled: Disconnect at 11.0 V fixed setting. Appropriate if bypass loads
draw current directly from the battery.
The controller is preset to Mode 1 from the factory. Changing the mode setting is
described below.
In case of doubts which mode to choose, consult your dealer because this has to be
evaluated depending on the battery used.
Settings
The controller can be configured for special operation. For this purpose, open the
cover of the controller by removing the screws on the back side.
WARNING: The controller should not be opened while connected and in opera-
tion!
When the controller is opened, there are 3 jumpers on the electronic board:

With these jumpers, the following settings can be configured:

General Safety and Usage Recommendations
Intended Use
The charge controller is intended exclusively for use in photovoltaic systems with 12 V
or 24 V nominal voltage and in conjunction with vented or sealed (VRLA) lead acid
batteries only.
Safety Recommendations
Batteries store a large amount of energy. Never short circuit a battery under all
circumstances. We recommend connecting a fuse (slow acting type, according to
the nominal controller current) directly to the battery terminal.
Batteries can produce flammable gases. Avoid making sparks, using fire or any naked
flame. Make sure that the battery room is ventilated.
Avoid touching or short circuiting wires or terminals. Be aware that the voltages on
specific terminals or wires can be up to double the battery voltage. Use isolated
tools, stand on dry ground and keep your hands dry.
Keep children away from batteries and the charge controller.
Please observe the safety recommendations of the battery manufacturer. If in
doubt, consult your dealer or installer.
Liability Exclusion
The manufacturer shall not be liable for damages, especially on the battery, caused by
use other than as intended or as mentioned in this manual or if the recommendations
of the battery manufacturer are neglected. The manufacturer shall not be liable if
there has been service or repair carried out by any unauthorized person, unusual use,
wrong installation, or bad system design.

Remedy
Load will reconnect as
soon as battery is
recharged.
Switch off all loads.
Remove short circuit.
Controller will switch
on load automatically
after max 1 minute.
Check if other sources
overcharge the battery.
If not, controller is
damaged.
Check battery wires,
fuses and battery.
Change battery
