LOAD DISCONNECT 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 VOLTAGE 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 VOLTAGE SENSE" terminals to resolve.
LOADS DISCONNECTED TOO SOON OR NOT RECONNECTING
See General Note #6 above: The battery may not be reaching the reconnect voltage set-point.
See General Note #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 "NO LVD" position the load will
not be disconnected.
LOADS ALWAYS DISCONNECTED, LVD LIGHT OFF, BATTERY VOLTAGE IS HIGH
Check the load circuit breaker on the front of the controller. If the breaker is tripped, the load
will not operate.
