victron energy CAN-bus Temp.sensor 1.5 - Alarm Out 3.7 - Electr 1.5 - 240Vcc

Applications:

• Temperature-dependent charging voltage regulation at (excessively) low temperatures

General characteristics:

• Battery temperature monitoring
  • Supply voltage 4..36VDC
  • Electricity consumption 60mA (@13.6V)
  • Output to switch off heavy user
  • LED status indicators
  • CAN.bus for control purposes and buck-boost converter and/or Quattro, MultiPlus and Venus GX communication
• Alarm output

General description:

The CAN.bus temp sensor is an accessory that is specifically developed for all models of buck-boost DC-DC converters.

The temperature is transmitted to the buck-boost DC-DC converter via a communication cable via the CAN-bus communication ports

The CAN.bus temp sensor can also be used in combination with any Victron Multi or Quattro. This enables the charging voltage to be regulated in line with low temperature.

For LiFePO4 lithium systems, this sensor is necessary in many system applications, due to the fact that LiFePO4 batteries must not be charged up when they are too cold. Charging lithium batteries at or around freezing point will cause permanent damage to the cells.

	CAUTION!Do not expose the product to heat sources (solar radiation, heating, etc.).Avoid additional heating of the product.Install the product in a dry place protected against splashing water.

Safety at the electrical connection of the product

	DANGER!Risk of fatal electric shock!When working on the electrical system, make sure that someone is around who can help in case of an emergency.When installing on boats: Improper installation of electrical appliances on boats can cause corrosion damage to the boat. Have the product connected by a qualified electrician.
	WARNING!Provide a sufficient cable intersection.Mount the cables so that they cannot be damaged by doors or hoods. Crushed cables can lead to life-threatening situations, and should be replaced.Install the cables in such a manner that they cannot be tripped over, and any damage to cables is excluded.
	CAUTION!Use wire conduits if cables are to be routed through sheet walls or other feedthroughs with sharp edges.Do not combine an AC cable and DC cable in the same channel (wire conduit).Do not loosen the conduits or sharply kink them.Attach the cables with the right materials and tools.Never pull the cables, take sufficiently long cable lengths of sufficient intersection in relation to its length.

Safe use of the product

WARNING!If the product is used in environments with lead-acid batteries, the room should be well ventilated. Explosive hydrogen gas is released from these batteries, which can be ignited by electric sparks.CAUTION!Do not use the appliance– in a salt-containing, damp or wet conditions– nearby aggressive vapours– near flammable materials– in explosive environmentsBefore use, check that the cables and connections are dry.Always disconnect the power supply when working on the product.Parts of the product may still be energized after the product has been disconnected.Do not disconnect cables when the product is still in use.

CAUTION!Prevent the product from being covered or being installed in a space that is too small.Provide proper ventilation.

Safety when handling batteries

WARNING!Batteries may contain harsh and corrosive acids. Avoid any and all physical contact with the battery fluid. In case of skin contact with battery fluids, wash the affected areas of the skin with water.In case of injuries due to acids, please be sure to consult a physician.CAUTION!When working with batteries do not wear metal objects such as watches or rings.Lead-acid batteries can cause short-circuit currents that can lead to serious burns.Risk of explosion!Wear protective goggles and safety clothing when working on batteries. When working with batteries, do not touch your eyes.Do not smoke and make sure there are no sparks nearby the engine or the battery.Do not attempt to charge frozen or defective batteries. In this case, place the battery in a frost-free room and wait until the battery is at ambient temperature. Then start the loading procedure.

CAUTION!Use only rechargeable batteries.Use sufficient cable intersections.Secure the positive cable with a fuse.Prevent metal parts from falling on the battery. This may result in sparks or short-circuiting of the battery and other electrical parts.Pay attention to the correct polarity when connecting.Please observe the battery and equipment manufacturers' instructions listed in corresponding manuals.In case the battery needs to be removed, always disconnect the ground connection first. Then disconnect all other connections and disconnect all consuming points from the battery before removing it.

Installation

Important!

Basic settings

When using the device for the first time, the following basic settings must be applied:

Programming the threshold value

• Connect the CAN-bus temp sensor to an 800C/1600 using the CAN-bus cable
• Tick checkbox 80 and enter the desired parameters
• Click on "Send all settings to converter"
• No more than 4 seconds later, the green LED on the CAN-bus temp sensor will flash 3 times to confirm

80

CAN bus external temperature sensor

Maximum output current: 5 A when T <= 0 °C

Converter is switched off when T <= -5 °C

After starting up the 800C/1600 or after a reset, it will take no more than 4 seconds before the CAN-bus temp sensor sends a CAN message to the converter. Until a message has been received, the words "no signal" may be displayed in the TSConfig monitor window.

If the connection to the CAN-bus temp sensor is lost (due to a cable break), the 800C/1600 will indicate "no signal" no more than 12 seconds afterwards. If this happens, the temperature threshold programmed in on the 800C/1600 will not be used to limit the charging voltage.

Setting the CAN-bus temp sensor as a stand-alone module

If the CAN-bus temp sensor is being used as a stand-alone module, a temperature (alarm) threshold value must be programmed first of all.

Programming a threshold value can only be carried out using an 800C/1600 and TSConfig Software.

Alarm

If the temperature has reached the threshold value (= converter off), the converter will be switched off (switching on will be blocked).

The block will not be lifted until the temperature has risen above the alarm threshold for a period of 5 minutes.
