Product Manual

• Function allow to choose between “Charger” or “Power supply”. When charger mode is selected, the Orion Smart will follow
the three state charge algorithm. For more information about the charge algorithm, please read the Orion Smart manual.
• Battery settings allow to change the battery settings in order to adjust the absorption voltage, float voltage and others to fit the
battery being charged. The battery setting is explained better on the next item.
• Input voltage lock-out allow to choose between two thresholds. One to set the lock-out and another one to reset it. Normally,
a minimum 0.5V (for 12V input Orion Smart) difference is used for a better performance. The protection can still be disabled if
desired by the user. For more information about the input voltage lock-out, please read the Orion Smart manual.
• Engine shutdown detection allow to choose between two thresholds. One to set the detect the engine shutdown and another
one to detect when it is running. Normally, a minimum 0.2V (for 12V input Orion Smart) difference is used for a better
performance. The engine shutdown detection can still be disabled if desired by the user. For more information about the engine
shutdown detection, please read the Orion Smart manual.
8.3.2. Charger Mode - Battery Settings
• Charger enabled
• Toggling this setting turns the Orion Smart off. The batteries will not be charged.
• Charger settings - Battery preset
• Battery preset allows to select the battery type; accept factory defaults; or enter your own preset values to be used for the
battery charge algorithm. The Absorption voltage, Float voltage, Bulk time limit, Re-bulk voltage offset, Adaptive absorption
time and Absorption time, settings are all configured to a preset value - but can be user-defined.
• User-defined presets can be stored in the preset library - in this way installers will not have to define all the values each time
they are configuring a new installation.
• By selecting Edit Presets, custom parameters can be set as follows:
• Absorption voltage
• Set the absorption voltage
• Float voltage
• Set the float voltage
• Bulk time limit
• Set the maximum bulk time allowed for the charger.
• Re-bulk offset voltage
• The re-bulk offset voltage determines what is the offset between the float voltage (or absorption if it is lower) and the re-
bulk voltage. The re-bulk voltage is the battery voltage threshold that triggers another charge cycle. For example, when
the charger cannot maintain the battery voltage due to a high load, the battery voltage will fall and a new charge cycle
will be started once the battery voltage drops below the re-bulk voltage.
• Absorption time
• The absorption time depends on if the Adaptive absorption time algorithm will be used or not. If that setting is not set,
the charger will use a Fixed absorption time, selected by the user. Now, if the adaptive absorption time is set, then the
charger will determine the absorption time based on the bulk elapsed time of that charge cycle, the Maximum
absorption time in this case is also set by the user.
8.3.3. Power Supply Mode
When on Power Supply Mode, these are the available settings.
