ADJUSTMENTS
Prior to the installation, open the lid of the device and cut through the component that is intended in accordance with your chosen controller option. If you are in doubt
which component is to be cut through, please consult your solar system retailer. Cutting through or removing components that are not mentioned according to the
instructions will void the warranty.
Rated voltage
If the controller is to be used in systems with 24 V, the resistor R 1 must be cut through. After setting the rated voltage, one of the following additional options can still be
adjusted in the device.
Changeover to constant final discharging voltage
When batteries with a large internal resistance (small battery capacity or already sulfated batteries) are used, the variable deep discharge cutoff may lead to a premature
load cutoff. For such cases, the I-output is not connected with load minus.
Surplus management
Connect the l-output to the battery minus terminal. If consumer loads are to be operated only when the battery is already charged, the bridge JP1 must be cut through. In
order to use the surplus principle in 24 V systems, the resistor R2 must also be cut through, apart from the bridge JP1.
Priority principle
Do not connect the I-output anywhere.
The adjustment can be selected in such a way that consumer loads connected to a controller are switched off at different times, like consumer loads on another controller
with the corresponding adjustment. This allows the allocation of a priority to the individual consumer loads, as illustrated by the following example.
Unimportant consumer loads (e. g. garden pond pump, television set) are connected to controller #1. Controller #2 later switches off the lighting, for example, while
controller #3 is the last one to switch off the consumer loads (e. g. emergency lighting, radio equipment). Controller #3 remains in the factory setting. On controller #2 R3
and on controller #1 R4 is cut through.
