installation or if the array has been manually disconnected that day. If the light stays on all
night every night, the timer may be defective.
BATTERY OVERCHARGING
CONTROLLER ALWAYS IN FULL CHARGE ("CHARGE MODE" LIGHT ON)
See General Note #6 above: The battery may not be reaching the charge termination set-point.
See General Note #3 above: No voltage at the battery sense terminals tells the controller that the
battery voltage is low and needs to be charged more. Install a connection from battery to
"BATTERY SENSE" terminals to resolve.
See General Note #8 above: A damaged temperature sensor or wire will cause the controller to
malfunction and requires immediate replacement.
CONTROLLER NOT IN CHARGE MODE ("CHARGE MODE" LIGHT OFF)
Disconnect array, then reconnect. Listen for relay to click and for “Charge Mode" light to come
back on. If the light goes on but you hear no click, the relay or controller may be defective.
Check for other charging sources that are not properly regulated, causing the battery to
overcharge.
LOAD DISCONNECT (LVD) CIRCUIT NOT OPERATING CORRECTLY
LOADS ALWAYS DISCONNECTED, LVD LIGHT ON, EVEN WHEN BATTERY VOLTAGE IS
HIGH
See General Note #6 above: No voltage at the battery sense terminals tells the controller that the
battery voltage is low and loads need to be disconnected. Install a connection from the battery
to "BATTERY SENSE" terminals to resolve.
LOADS DISCONNECTED TOO SOON OR NOT RECONNECTING
See General Note #4 above: The battery may not be reaching the reconnect voltage set-point.
See General Notes #12 and 14 above: A poor connection between the controller and the battery
results in a voltage drop when heavy loads are turned on that disappears when the loads are
turned off. The heavier the loads are, the larger the voltage drop will be. This voltage drop
results in the controller seeing a lower voltage than what the battery voltage actually is.
LOADS NOT DISCONNECTING ON LOW VOLTAGE, LVD LIGHT OFF
Check the position of the "LVD" switch. If the switch is in the "OFF" position the load will not be
disconnected.
LOADS ALWAYS DISCONNECTED, LVD LIGHT OFF, BATTERY VOLTAGE IS HIGH
