Orion-Tr Smart DC-DC Charger Isolated

EN ES IT PT CZ TR
1. General Description
The Orion-Tr Smart DC-DC Charger Isolated 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. Controlled charging will also
protect the alternator in lithium systems where direct charging can
overload the alternator due to the low impedance of the lithium
battery. In fixed output mode the output voltage will remain stable
independent of the applied load or varying input voltage (within
the specified range).
The Orion-Tr Smart DC-DC Charger Isolated can be set up to
only provide power when the engine is running. This is possible
thanks to the built-in engine shutdown detection. This also
prevents the onboard voltage of the vehicle from becoming too
low. It is not necessary to intervene in the system of the vehicle,
to install a separate motor run sensor or to intervene in the CAN-
bus system. Apart from this detection, the Orion-Tr Smart DC-DC
Charger Isolated can also be activated by a forced allowed to
charge feature, e.g. connected to the ignition switch.
The Orion-Tr Smart DC-DC Charger Isolated is fully
programmable with the VictronConnect app.

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 a engine running detection mechanism. This
prevents the converter from discharging the starter battery when
the alternator does not supply power. See section 5 of this
manual for more details.
Separation of the starter battery and the service battery
The Orion-Tr Smart DC-DC Charger Isolated separates the
starter battery from the service battery when the engine is not
running.
Extensive electronic protection
Over-temperature protection and power derating when
temperature is high.
Overload protected.
Short circuit protected.
Connector over-temperature protection.
Adaptive three step charging
The Orion-Tr Smart DC-DC Charger Isolated is configured for a
three-step charging process:
Bulk – Absorption – Float.
Bulk
During this stage the controller delivers as much charge current
as possible to rapidly recharge the batteries.
Absorption
When the battery voltage reaches the absorption voltage setting,
the controller switches to constant voltage mode. For lead acid
batteries it is important that during shallow discharges the
absorption time is kept short in order to prevent overcharging of
the battery. After a deep discharge the absorption time is

3
EN ES IT PT CZ TR
automatically increased to make sure that the battery is
completely recharged. For lithium batteries absorption time is
fixed, default 2 hours. The fixed or adaptive mode can be chosen
on the battery settings.
Float
During this stage, float voltage is applied to the battery to
maintain it in a fully charged state. When the battery voltage
drops substantially below this level, due to a high load for
example, during at least 1 minute, a new charge cycle will be
triggered.
Flexible charge algorithm
Programmable charge algorithm, and eight preprogrammed
battery settings.
Configurable with VictronConnect.
Adaptive absorption time
Automatically calculates the proper absorption time.
Configurable with Victron Connect.
Configuring and monitoring
Bluetooth Smart built-in: the wireless solution to set-up, monitor
and update the controller using Apple and Android smartphones,
tablets or other devices.
Several parameters can be customized with the VictronConnect
app.
The VictronConnect app can be downloaded from:

Use the manual – VictronConnect - to get the most out of the
VictronConnect App when it’s connected to an Orion Smart:

Input voltage lock-out
Shutdown if the input voltage drops below the lock-out value and
restart when the input voltage increases above the restart value.
Configurable with Victron Connect.

Remote on-off
Use the remote function to enable and disable the converter
remotely with the remote on/off connector or using the
VictronConnect app. Typical use cases include a user operated
hard wired switch and automatic control by for example a Battery
Management System. If the minus of the service battery is not at
the same potential as the minus of the alternator or starter battery
an isolated remote on/off cable between the BMS and the on/off
port is required, see chapter 4.4 for details.

installation and maintenance.
•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. in the immediate vicinity of the equipment.
•It is normal for the Orion-Tr Smart DC-DC Charger Isolated to
get hot during operation, keep any objects that are heat-
sensitive away.

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).

4.4 Connection remote on-off
The recommended use of the remote on-off is:
a) A switch wired between the L-H pins (On-level impedance
between L-H pins: <500kΩ)
b) A switch wired between (input/starter) battery plus and H-pin
(on level: >3V)
c) A switch between the L-pin and (input/starter) ground (on level:
<5V)
d) Isolated remote on-off cable e.g. controlled by a (mini)BMS
Note: Voltage tolerance L & H pin: +/- 70VDC
a) L-H pin wiring
b) H-pin wiring
c) L-pin wiring
d) Isolated remote on-off cable

4.5 Engine detection override
In charger mode the “engine on detection sequence” determines
if conditions are met to enable charging, see chapter 5. The
“engine detection override” forces the charger to allow charging
independent of the engine on detection. Engine detection
override is activated by applying >7V to the remote L-pin. This
allows external control (e.g. ignition switch, CAN bus engine on
detector) to enable charging.
This function does not override the remote function. Therefore,
remote connection a), b) or d) must be configured in combination
with engine dection override. See examples in figure 4.

5. Smart alternator compatibility
The engine is running detection is based on the voltage of the
starter battery. The charger is not always able to measure the
exact starter battery voltage because of voltage drop over the
input cable. The voltage drop is determined by variables like
current, cable length and cable gauge. The “engine on detection
sequence” (see figure 7) will perform periodic tests to determine
the exact starter battery voltage during charging. The test result
determines if the engine is running and charging can be enabled.
This feature is only active in charger mode and when “engine
detection override” is not activated. In converter mode the “input
voltage lock-out” determines when the output is active.
Configurable with VictronConnect
Figure 7: Engine on detection sequence

13
EN ES IT PT CZ TR
0 1:
When the engine runs the alternator voltage will ramp-up, when
Vstarter increases above Venable, charging starts.
1 2:
Due to the charge current a voltage drop will occur across the
input cable (Vcable), this voltage reduces the voltage at the input of
the charger (VIN). While VIN remains above Vtest, charging is
enabled.
2 3:
If VIN drops below Vtest, the “engine on detection sequence” is
started. Every 2 minutes the charger is paused for 10 seconds to
measure the voltage. Without current flow VIN is equal to Vstarter, if
VIN is above Vtest, charging will resume. While remaining in this
state, the test is performed every 2 minutes.
3 4:
During the detection sequence VIN dropped below Vtest, this
means that the engine stopped running and charging must be
stopped, the charge sequence is paused.
4 5:
VIN increases above Venable, the charge sequences continues.
