• Install the product in a heatproof environment. Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc. in the immediate vicinity of the equipment. • It is normal for the Orion XS 12/12-50A DC-DC battery charger to get hot during operation. Keep any objects that are heat-sensitive away.
2. General 2.1. Introduction The Orion XS 12/12-50A DC-DC battery charger (called Orion XS in this manual for convenience) can be used as a battery charger or as a power supply with a wide input and output voltage range. In charger mode, the four-stage charge algorithm will increase battery life by properly charging the battery.

Manual - Orion XS 12/12-50A DC-DC battery charger 3.5. GND connection In many cases, the GND connection is connected to the chassis via a cable lug. For a low-impedance connection, the cable lug must have direct contact with the metal of the chassis, the contact surface must therefore be free of paint, see below images.
Manual - Orion XS 12/12-50A DC-DC battery charger 3.7. Connection setup for DC-DC power supply mode Disconnect the remote on/off (remove the wire bridge or remove the entire remote on/off terminal block). Connect the input power cables. Open the VictronConnect app to set up the product (always adjust the output voltage before connecting a load or battery to the output).
Manual - Orion XS 12/12-50A DC-DC battery charger 3.9. Connection setup for remote on/off The recommended use of the remote on/off input is: A switch wired between the L-H pins (ON switch level impedance between L-H pins: < 30kΩ) A switch wired between (input/output) battery positive and H pin (ON switch level > 4V) A switch wired between the L-pin and (input/output) ground (ON switch level <...
Manual - Orion XS 12/12-50A DC-DC battery charger 3.10. Engine shutdown detection override wiring In charger mode, the engine shutdown detection sequence determines whether the conditions are met to enable charging; see Engine shutdown detection [12] chapter. Overriding the engine shutdown detection allows the user to decide for himself whether charging is allowed.

Manual - Orion XS 12/12-50A DC-DC battery charger 4. Operation, configuration and monitoring 4.1. Engine shutdown detection The engine shutdown detection mechanism simplifies your Orion XS system by detecting if the engine is running without wiring additional switches or sensors. The factory default setting will work with most conventional and smart alternators but can be re-configured with the VictronConnect App.

Manual - Orion XS 12/12-50A DC-DC battery charger Shutdown voltage (V ): This level corresponds with the engine being shutdown off. This keeps the starter battery fully charged and provides a hysteresis with respect to the start level. The hysteresis must be large enough to prevent V drop to V which would result in charge current reduction.

Manual - Orion XS 12/12-50A DC-DC battery charger The float stage starts when the batteries are 100% full. During the float stage the charge current is very low. To find out what the state of charge (SoC) of the battery is, check the battery monitor (if present), or alternatively, check the charge stage the Orion XS is in.
Manual - Orion XS 12/12-50A DC-DC battery charger 5.2.6. Insufficient alternator power Check if the Orion XS reaches the float charge stage. To investigate, look at the history tab in the VictronConnect app. The histogram displays how long the batteries have been charged in the Bulk, Absorption and Float stages for the last 40 cycles. If you click on one of the histogram columns, you will see a breakdown of the charge stages.
Manual - Orion XS 12/12-50A DC-DC battery charger 5.3.3. Battery old or faulty A battery that is at the end of its service life or has been damaged by incorrect use can be prone to being overcharged. A battery contains a number of cells that are connected in series. When a battery is old or has been damaged, a likely scenario is that one of these cells is not operational anymore.
