8.7 Self test
The self test can be used to check if the charge
controller is functioning correctly. It also allows
localisation of possible errors.
The self test can only be performed within 5 minutes
of a Power-On Reset (controller start-up through con-
nection of power to the battery connection). After
this period, activating the function causes "InF" to be
displayed (left Fig.).
Perform the self test as follows:
1. Disconnect the solar module.
2. Disconnect load.
3. Disconnect the battery.
4. Reconnect the battery after waiting for 30 seconds.
5. Select the "Self test" menu item within 5 minutes (upper Fig.).
6. Press the right button; the display flashes.
7. Press the left button; the self test starts.
8. Only when "InF" is displayed:
Disconnect the battery, wait 30 seconds, reconnect the battery, pro-
ceed from step 5.
9. The error code is displayed for a number of seconds (see table below).
If an error code other than 000 is displayed: Note the code and contact
a Steca dealer with this information for error analysis.
10. All segments are displayed and then hidden, then the self test window
is displayed again (upper Fig.).
11. In the flashing self test window, press the left button to repeat the self
test or press the right button to end the self test.
