Product page: https://vutlan.com/can-sensors/25-vt430-rack-control.html

Function

The unit has all possibilities for rack control, a PIR sensor for door control, 2 dry contacts, and temperature and humidity sensors.

Physical description

  


1. "TR" - is the nearest switch to CAN inputs. This switch should be turned "ON" on the last sensor in the CAN chain. The last sensor in the long chain with a length of more than 10 meters, the terminator should be in "OFF" position.

    "FR" - the memory switch, is necessary for reprogramming the module (the switch remote from the CAN connectors).

Do not use the DIP switch "FR", it should always be OFF. If this switch is turned ON, the module will turn off. This switch is only needed for programming purposes!

2. "CAN" - two equivalent digital connectors RJ12 for the connection of CAN sensors and CAN extensions on a CAN bus, with auto-sensing.

3. "1, 2" - Dry contact inputs terminals, can be used for access control.

4. "Sensor" - Temperature and humidity sensor

5. "LEDs" - LEDs: "RUN" - indicates appliance connection status to the main module, "ERR" - indicates appliance lost connection to the main module.

6. "PIR" - Door IR access sensor. Use a white sticker supplied to control the door open/closed.

Installation

There is a mounting bracket on the unit. Fix unit by M5 or M6 bolts on the cabinet or the rack profile in front of the door. Glue the white sticker on the door in front of the unit IR sensor. Connect CAN input of the unit by RJ11/RJ12 cable supplied to the CAN input of the previous CAN unit or monitoring system. The red LED lights up. Match the TR bus terminators on the attached CAN units. CAN bus terminators TR (position 2 in VT450) should be in the ON state only at the end CAN units port and in Off states (1,2) for all intermediate units. One CAN bus can have not more than 8 CAN units, sensors, and/or another CAN device. 

If necessary, connect dry contacts, door sensors, or triggers to the unit.


Connection

To connect the CAN unit to the system, open the interface and go  CAN Configuration  Select tab CAN.

Click "Configure" and wait. The system starts the CAN bus line survey, and displays the list of connected CAN units and sensors. On the CAN devices, the green LEDs light up.

If you will go now to the "System tree", there you will see new CAN devices and/or new CAN sensors. Wait for a little or renew the tree.

If the survey is reset after clicking "Configure", it means that the line is not connected (bad cable and/or bad connectors) or not matched terminators on the bus. It is necessary to check and change the status of the line or the TR terminations.

CAN devices connection

This section includes child pages:

CAN sensors and CAN units connection

  1. Connect CAN devices to any port CAN1 or CAN2 on the monitoring system using a cable supplied. CAN sensors can also be connected to the port of another CAN sensor or CAN unit which is connected to the CAN bus. Determination of the devices and their connection is done through a web interface.

    You can connect up to a maximum of x12 CAN sensors and CAN devices together on one CAN bus (approximately)!

    If you want to connect more than x12 CAN units, you need to use CAN-12V-1A / CAN Power Supply

  2. The TR should be "ON" for the last sensor on each bus "CAN 1" and "CAN 2". See section "TR" below.

This procedure applies to the following sensors, which are supported by the appliance and are connected to the CAN ports:

CAN sensors, modules:

CAN extensions:

Used cable and limit line length

The maximum length of the CAN line in Vutlan monitoring systems is 225 m due to limitations on the ohmic resistance of cables with RJ12 connectors.

It is advisable to use two or three pairs of cables such as UTP Cat3.5.6 with 24AWG with a copper core. It is possible to use a 4-wire or 6-wire TRONIC or UTP CCA cable, but the maximum CAN line length will be reduced.

TR termination switch

The last sensor TR switch on a CAN chain must always be terminated, ( switched ON ). Sensors on a CAN bus that is in the middle should have TR switched OFF.

FR should always be OFF.

TR switch is always the DP switch nearest to the CAN bus.

Only older Vutlan models have an FR switch.

Adding CAN modules and sensors

To connect the CAN module or CAN sensor to the CAN bus of the system, go to the interface >> CAN configuration panel >> Select the CAN1 or CAN2 tab (select the connected physical CAN1 or CAN2 port on the master module).

Click the "Configure" button and wait. The system will start CAN bus polling, soon it will display the data lines and write “Done!”. The modules and sensors connected to the CAN input will appear in a tab in the list. Click the Apply button and then Restart.

The green LED "CAN status" of the device will light up.

Go to panel "System Tree" to see the new devices or new sensors. The article numbers for CAN devices are VT4xx. If they do not appear, wait, or refresh.

If after clicking the "Configure" button the poll is reset to the phrase "Update", then the line is not connected or the terminators on the bus are not agreed. It is necessary to check and change the condition of the TR terminators (See "TR termination switch" section above) on the modules or check and possibly change the connection cables.


Warning: If the bus is not matched, that is, there are bad contacts or bad cables, or the TR terminator is in the"ON" position on the intermediate devices (position 2 on the VT408), or the line is too short for matching on both CAN end devices, CAN on this line can work malfunctioning, or the line as a whole may not function. (CAN line failure may occur if the parallel CR switch is in state 1, must be in OFF).


LEDs

CAN sensors have LEDs that indicate the following states:

  • Red continuous light, green flickers - no communication with the master module

  • Red continuous light, green is off - there is a connection with the master unit, but is not included in the monitoring system (not configured)

  • Red is off, Green continuously light - work as part of a monitoring system

  • All LEDs are off: no power or sensor is defective.

Configuration

CAN bus is used for connection of CAN sensors and CAN modules. The device has two independent CAN nodes: CAN1 and СAN2.

Before using CAN sensor module, CAN bus must be configured to operate with this CAN sensor module. To configure CAN bus go to "Main menu" >> "CAN" menu, which in turn has two identical tabs - one for each node.

Each station tab contains current information on the status of the node and a list of  CAN sensor modules connected to this node. 

The following operations can be carried out on the CAN bus node:

  • Refresh - updates the current information on the status of the node;
  • Configure -  launches configuration process of the nodes for CAN sensor modules connected to it, the old configuration is lost
  • Save - saves the list of CAN sensor modules in flash memory;
  • Restart - restarts the CAN bus node.

To delete a CAN sensor module, click on the desired module. A modal window will pop up. Press "Delete" and confirm.

To set up a CAN bus node for operation with the CAN sensor module, connect CAN module to CAN network and run corresponding configuration procedure in the web interface using the command "Configure". The configuration process is displayed at the bottom of the tab and lasts approx. 2 minutes.  Detected modules will be added to the list of modules during the configuration process. After completing configuration the node returns to its normal operation. Sensors of detected CAN modules are added to the tree of elements. 

The names of the sensors are automatically set in the form {module name}{serial number}-{type of sensor} and can be edited.

If you need to remove CAN sensor module from the configuration list use command Delete, then use command "Save" to apply the changes you made and restart the node using the command Restart.
