Orion-Tr Smart DC-DC Charger Non-Isolated 1. General Description The Orion-Tr Smart DC-DC Charger can be used as a power supply or as a battery charger. In charger mode the three-state charge algorithm will increase battery life by properly charging the battery. Especially in the case of vehicles with a smart alternator, or voltage drop caused by long cable runs, controlled charging is indispensable.
Orion-Tr Smart DC-DC Charger Non-Isolated 2. Features Smart alternator compatibility Vehicle manufacturers are now introducing smart ECU (Engine Control Unit) controlled alternators to increase fuel efficiency and reduce emissions. Smart alternators deliver a variable output voltage and are shut down when they’re not needed. The converter has an engine running detection mechanism. This prevents the converter from discharging the starter battery when the alternator does not supply power.
Orion-Tr Smart DC-DC Charger Non-Isolated 3. Safety instructions SAVE THESE INSTRUCTIONS – This manual contains important instructions that shall be followed during installation and maintenance. Danger of explosion from sparking Danger of electric shock • Please read this manual carefully before the product is installed and put into use • Install the product in a heatproof environment. Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc.
Orion-Tr Smart DC-DC Charger Non-Isolated 4. Installation 4.1. General • Mount vertically on a non-flammable surface, with the power terminals facing downwards. Observe a minimum clearance of 10 cm under and above the product for optimal cooling. • Mount close to the battery, but never directly above the battery (in order to prevent damage due to gassing of the battery). 4.2. Connection setup for DC-DC converter mode 1. Disconnect the remote on/off (remove wire bridge). 2. Connect the input supply cables.

Orion-Tr Smart DC-DC Charger Non-Isolated 4.5. Engine shutdown detection override In charger mode the “engine shutdown detection sequence” determines if conditions are met to enable charging, see chapter 5. The “engine shutdown detection override” forces the charger to allow charging independently of the engine shutdown detection. Engine shutdown detection override is activated by applying >7V to the remote L-pin. This allows external control (e.g.
Orion-Tr Smart DC-DC Charger Non-Isolated Figure 5: Disable engine shutdown detection When the engine shutdown detection has been switched off in Victron Connect (‘forced charging’) current will be drawn from the starter battery even if the engine is not running. During ‘forced charging’ the input voltage lockout is the only limit left to disable charging automatically, make sure this level is not set too low, in most applications 12.5V is sufficiently low. 4.6.

Engine shuthown detection The engine shutdown detection mechanism simplifies your ORION-Tr DC-DC Charger system by detecting if the engine is running without wiring additional switches or sensors. The factory default setting will work with most regular and smart alternators but can be re-configured with the VictronConnect App. Configuring the engine shutdown detection depends on the voltage generated by the alternator when the engine is running.
Orion-Tr Smart DC-DC Charger Non-Isolated Figure 9: Engine shutdown detection setup menu The following settings can be changed with VictronConnect: The default values displayed are for the 12V input models. Those values are scaled depending on the input voltage of the model. E.g. for 24V input models, the default values displayed on the manual should be multiplied by 2. Engine shutdown detection enabled: The engine shutdown detection is always enabled by default when the charger mode is selected.
Orion-Tr Smart DC-DC Charger Non-Isolated If the low voltage period exceeds tshutdown charging will be disabled on engine shutdown detection. • Voltage drop across the input cable: As seen in “engine shutdown detection sequence 1→3”, VIN will be lowered by Vcable. When the alternator voltage drops fast (smart alternator) the charge-control needs some time to reduce charge current and keep VIN at Vshutdown. During this time Vcable must not trip the voltage lock-out.

This guide will help you get the most out of your Orion Smart DC-DC Charger and it requires a minimum knowledge of this charger that can be found in the introduction. The information available here applies to all Orion Smart DC-DC Chargers. To simplify the reference to the Orion Smart DC-DC Charger, it will be refer as just Orion Smart in this guide.
Orion-Tr Smart DC-DC Charger Non-Isolated 8.2.2. Charger Mode - GRAPH tab • Orion Smart [SERIAL NUMBER] confirms the connected device. A custom name can also be set if desired. • Charger State Graph indicate in which state the charger currently is and show a short description of the current state. 8.2.3. Power Supply Mode • Orion Smart [SERIAL NUMBER] confirms the connected device. A custom name can also be set if desired.
Orion-Tr Smart DC-DC Charger Non-Isolated • 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.
Orion-Tr Smart DC-DC Charger Non-Isolated • Function allow to choose between “Charger” or “Power supply”. When power supply mode is selected, the Orion Smart will keep the output voltage as set on the setting. • Output voltage allow to choose the output voltage when power supply mode is selected. Note that the minimum and maximum voltages needs to be within the product limit (i.e.: 10V to 15V for 12V output Orion Smart) • Input voltage lock-out allow to choose between two thresholds.
