Special conditions are shown in the LCD display if the Low Voltage Disconnect
function shuts off the load output or in case of various other error conditions.
See section ERROR DESCRIPTION for details.
Acoustics Signals
The controller has an acoustic signal which indicates the change of the state of
charge. This function can be deactivated in Programming Menu 7.
Description of Functions
Low Voltage Disconnect Function (LVD)
The controller has 5 different modes to protect the battery from being deep
discharged:
Mode 1: Disconnect at 11.4 V (at nominal load current) up to 11.9 V (at no load
current). Normal operation mode for good battery protection.
Mode 2: Disconnect at 11.0 V (at nominal load current) up to 11.75 V (at no
load current). Mode with lower disconnection point. Battery is cycled deeper,
this can shorten battery lifetime.
Mode 3: Disconnect at 11.0 V to 12.2 V depending on load current and previous
charging cycles. This adaptive mode leads to longer lifetime of the battery because
it allows recovery of the battery by full recharge. Maximum battery life.
Mode 4: Disconnect at 11.5 V fixed setting. Appropriate if bypass loads draw
current directly from battery.
