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.).
Afterwards, all LCD segments fade in and out for 1 second.
Then the auto-test window reappears in the display.
E) If there is a defect or the module and load is still connected
you will see an error code:
1. digit = “1” : module input defected
2. digit = “1” : load output defected
3. digit = “1” : battery fuse defected
F) In the flashing auto-test window, press the left button
again to repeat the test or the right button to end the test.
6.8. Serial Number Query
Each regulator has a serial number that can be queried using
this window. Press the right button and the SN display begins
to flash. Now, press the left button to display the number. The
digits are displayed successively: - - - 1 2 3 4 5 6 7 8 - - - .
Press the right button to stop or continue the display.
Note the order of the digits for the complete serial number.
7. Options
7.1. External temperature sensor
If the solar battery will be operated under a large temperature range (winter/summer)
the optional external temperature sensor should be used. A temperature compensated
final charge voltage will extend the batteries lifetime and uses the optimum charge
capacity (see appendix).
7.2. Alarm contact
For remote monitoring of an alarm condition the PR2020-IP is available with an alarm
contact. The contact closes, if the SOC of the battery falls below 40 % or if a system
error occurs.
Notes: The external sensor can be installed by the end user, the alarming option
has to be mounted in the factory.
