Testing Function
Pushing the test button on the CIS-CU (Control Unit) will switch on load terminal for 1 minute.
Should pressing the button cause a load disconnect event (LVD/SOC, overcurrent) then the load will be switched off immediately.

Over temperature
Reduces the charging current if over temperature occurs and switches off the load if the temperature reaches a
high level.
(1) Panels are short circuited by diodes. The controller can therefore only be subjected to these conditions for a limited time. A battery connected to the
panel terminals in reverse polarity will instantly cause a damage to the controller.
(2) A battery fuse is necessary to protect the CIS-N-MPPT-LED 85/15 from getting damaged by reverse polarity connection on the battery terminals.
(3) Controller can protect itself, but any connected loads might be damaged.
(4) Short circuit: >3x – 20x nominal current.
(5) Battery must be protected by a fuse, or it might be permanently damaged in case of short circuit.
(6) MPPT switches off when detecting reverse current.
(7) At voltages above 85 V the MPPT will stop charging.
WARNING:
The combination of different error conditions may cause damage to the controller. Always remove the fault condition before you continue
connecting the controller!
