Installation of Orion Tr Smart

Installation of Orion Tr Smart

1. Preparation of cabling and fuses
• Incoming cabling (input): Ensure that the incoming power cable is secured with 60A. Use a robust cable and a secure fuse holder, such as Maxi Fuse Holder or circuit breakers. Avoid thin hanging fuses to minimize the risk of overheating and poor contact.
• Outgoing cabling (output): The outgoing power supply should be secured with double the strength of what the unit can deliver. Example: An Orion Tr Smart 12/12 30A should be secured with a 60A fuse on the outgoing cable.
• Cable size: Orion Tr Smart supports a maximum cable thickness of 16mm². For best performance, it is recommended to use the thickest cable possible.
2. Placement and Installation
• Mounting mode: Orion Tr Smart is IP43 rated for wall mounting, which means it is protected against the ingress of solid particles and water splashes from a certain angle. The unit should never be mounted lying on the floor, as this can negatively affect cooling and protection class.
• Mount the unit in a well-ventilated environment where it can cool naturally.
• Ensure that the installation is secure and that the cables are not at risk of abrasion or overheating.

Configuration of Orion Tr Smart

1. Connection via VictronConnect
• Connect to the device with the VictronConnect app. Note that most Victron products have the default PIN code 000000. For newer devices, a unique PIN code may be found on an accompanying sticker.
• When you have connected to the device, it may request a firmware update. Complete this before proceeding.
2. Basic settings
• Go to the settings and set Function as Charger instead of Power Supply.

3. Battery charging settings
• Under Battery Settings, set the charging profile depending on the battery type.
• For lithium batteries, the default lithium setting may need to be adjusted if the battery is not charging fully.
• Select Battery Preset and choose Smart Lithium as the profile.
• Adjust the voltage values to match the battery specifications if necessary.

4. Engine Shutdown Detection
• To ensure optimal function, set Engine Shutdown Detection to Smart Alternator. Adjust the Delayed Start Voltage time from 120s to 30s.
• If you have multiple DC/DC units in the system, it is recommended to set a difference of 0.1V in the start and stop voltage for each unit. This prevents all units from starting at the same time, which can unnecessarily burden the system.

5. Adjustment at charging start
• During the first few minutes, the DC/DC charger may start and stop a few times while it finds the correct charging current, especially if the unit is working together with a charger on the starter battery that has a lower maximum charging current.
• If problems arise with repeated interruptions, you may consider installing a more powerful charger.
