1. Safety instructions and liability disclaimer 1.1. The safety instructions are marked as follows In this manual, safety instructions for personal protection are marked with this symbol. The relevant operational safety notes of the system and regulator are marked in bold. 1.2.
This manual is a component of the system regulator and must be included with the regulator when given to a third person. The Controller is equipped with a low power surge protection. The installer had to care for a efficient lightning protection. 1.3.
1.4. Liability Disclaimer The manufacturer cannot monitor the compliance to this manual as well as the condi- tions and methods during the installation, operation, usage and maintenance of the system regulator. Improper installation can cause damages and endanger people. Therefore, we assume no responsibility and liability for losses, damages or costs that result due to incorrect installation, improper operation, usage and maintenance or in any manner associated therewith.
2. Installation 2.1. Installation Site Only install the regulator near the battery on a suitable surface. This surface should be solid, stabile, even, dry and nonflammable. The battery cable should be as short as pos- sible and have a suitable cable diameter size to minimize loss, e.g. 4 mm² at 20 A and 2 m length.
2.2. Connecting the Regulator Connect the individual components to the symbols provided. Observe the following connection sequence during commissioning: 1. Connect the battery to the charge regulator - plus and minus 2. Connect the photovoltaic module to the charge regulator - plus and minus 3.
3. Protective functions of the controller The regulator is equipped with various devices to protect its electronics, battery and load. If the regulator’s maximal permitted data are exceeded, the regulator can break down despite the protective functions. Never improperly connect more than one com- ponent to the regulator! Error messages (Point 7.
4. Operating the system regulator The display shows a variety of system data by symbols and digits. Both buttons control all settings and display windows. 4.1. Display and Operation Elements Display window for system information and messages Button for switching display ...
4.2.1. SOC Window Displays the charge level, day / night level and consumer on / off. Instead of the SOC value, the battery voltage is displayed during voltage control. 4.2.2. Voltage window Displays the battery voltage measured by the regulator. 4.2.3.
4.2.8. Warning deep discharge protection As an early warning, the SOC bar or the voltage value flashes. The face still looks friendly! 4.2.9. Load disconnection If the deep discharging protection has been activated the SOC bar or the voltage value flashes. The face looks sad until the reconnection setpoint is reached.
5.3. Deep Discharging Protection The regulator protects the connected battery against an excessive discharging. If the bat- tery falls below a specified charge level (during SOC control) or battery voltage (during the voltage-controlled function), the load output is disconnected and the discharge of the battery is prevented.
6.4. Night Light Function Setting This setting provides three options in the following order: • OFF: The function is deactivated (default). • Operating time-choice of 1 to 8 hours. • ON: The consumer output remains on for the entire night. This function controls the load output only when it is dark (at night).
6.7. Auto-test The auto-test can determine whether the charge controller is fully operational. A) Disconnect solar module and load from the regulator, con- nect only the battery. B) Press the right button. The display begins to flash. C) Start the auto-test with the left button. D) If there is no error, this window is displayed shortly (1 sec.).
8. Error Messages Caution! Please do not open the regulator or attempt to replace components when troubleshooting. Improper maintenance can be hazardous to the user and the system. If the regulator detects errors or unauthorized operating states, it flashes error codes on the display.

Appendix External temperature sensor for the PR 2020-IP In order to fully charge a lead battery, the end-of-charge voltage must be adjusted in accordance with the temperature. The external temperature sensor TSRIP8 is needed, if the range of the battery temperature is outside the standard range of 10 ... 25 °C. The external sensor can record the actual temperature of the battery.
Signal contact Optional available for the PR2020-IP is the alarm contact output. An alarm is raised if one or more of the following conditions is true. It reopens automatically if the alarm condition is cleared. The contact can handle max. 50 V, 100 mA. The alarm contact (dry contact) output is at pin #3 and #4.
