You can enter the programming mode with 2 seconds push on the button.
The programming menu structure is described on the follow page. Mind
that once you have entered the programming menu you can exit it at the
last item only. All programming settings are stored in a non-volatile
memory and remain stored even if the controller was disconnected from
the battery.
Programming your Solar Controller
The button switch has three push modes:
1
）
Short push
Shorter than 1 seconds
2
）
Long push
2 to 8 seconds
3
）
Lock push
8 seconds or longer
By pushing the button for 8 sec in normal operation mode the
programming lock-out is activated to prevent any accidental settings
change. Another 8 sec push releases the lock-out.
With a long push, you can enter the programming mode. The
programming menu structure is described in the back page. A wide arrow
means a long push (2s-8s), a narrow dotted line arrow means a short push
(<1sec).
Testing Function
During the daytime the testing function of SLAC-SL can help the user to
verify correct installation or for troubleshooting a system problem. Short
pushing the button will light up the lamp which is connected to the load
terminals. The lights will be on in the day for 3 minutes intervals. Within
3 minutes the lights can be turned off via pushing button. The lights can
turned on repeatedly with pushing button besides when the system is in
LVD (load disconnect/red LED on). In LVD this testing function is not
valid. If pressing the button cause a load disconnects (LVD) the light will
turn off.

Over
temperature
When over temperature occurs, the controller will
reduce the charging current. If the temperature of
controller reaches a high level, the load will
automatically be switched off.
(1) Controller can protect itself, but load might be damaged.
(2) We strongly recommend that add a fuse between battery and controller.
The battery may be permanent damaged when short circuit occurs.
(3) > 200% rated current: Load will be switched off with 3s delay.
Warning: Two or more error conditions at the same time may cause
damage to the controller. Always remove the present fault condition
before next operation
