MATERIAL NEEDED FOR THE INSTALLATION

CONTENTS OF THE WPC-CAN COMMUNICATION SET

The communication set WPC-CAN contains the following material:

One WPC-CAN module|
---|---
Two 2 meters communication cables, to connect the WPC-CAN to Whisper Power and external devices|
Mounting plate|
2 DIN rail clips and screws|
SD card with manual|

OTHER REQUIRED MATERIAL

Since the WPC-CAN is dedicated to communicate with a Sun track (and the WPC in some applications) You will need a specific cable with the proper connector and pinning on each side. See chapter 5.2

This device should not be used for any purpose not described in this manual. The device is using RJ45 connectors frequently used and standard for LAN (Local Area Network). The WPCCAN should never be used or plugged into communication networks other than the ones specified in this manual. This will seriously damage the product.

INSTALLATION OF THE WPC-CAN

Figure 1: Electronic board inside the WPC-CAN
INSTALLATION OF THE WPC-CAN

This device was designed for indoor use only and must under no circumstances be exposed to rain, snow or any other humid or dusty environment.

As far as possible, reduce exposure to sudden temperature variation: important heat variation may create undesired and harmful condensation inside the equipment.

The WPC-CAN has been previously prepared at the Whisper Power factory so that it is ready for use

CAN BUS SPEED

The WPC-CAN supports multiple speeds on the “CAN” side. This setting has been setup at the factory, and therefore it’s not necessary to change this setting later on. The default setting is 250kbps.

Position	CAN bus speed
6	7
OFF	OFF
ON	20 kbps
ON	OFF
ON	100 kbps
ON	OFF
ON	250 kbps
ON	OFF
ON	1 MPs

WIRING WPC-CAN

The task of the WPC-CAN is to let two separate can bus networks talk together. On the WPC-bus side we connect the untrack Pro or in some specific cases the WPC’s. WPC-bus side wiring is predefined and cannot be changed.

The CAN side is where it continues as whisper connect, and most like connects to a touch panel. Furthermore, the pinout on this side of the WPC-CAN has been setup in the factory (see illustration below) and does not require any altering.
WIRING WPC-CAN

MOUNTING

The WPC-CAN can be mounted directly on any support by means of the supplied fixing plate, on a smooth surface with double-side adhesive or on DIN rail using the DIN rail clips (part of the WPC-CAN communication set).
MOUNTING

CONNECTION OF THE COMMUNICATION BUS (WPC-BUS SIDE)

The Whisper Power bus is daisy chained to the other XT/VT/VS Whisper Power components and is powered by the communication plug as soon as the upfront device is powered. The WPC-CAN module should not be installed between 2 devices powered by the battery. Connect the WPC-CAN module with the supplied cable (2m). This cable should not be extended.

Do not connect the WPC-CAN between devices connected to the battery. Do not connect the module to a device not connected to the battery (RCC or other ExCom).

The termination switch of the communication bus “Com. Bus” remains in position T (terminated) except when both connectors are used. In this case and only in this case, the switch must be placed in the O (open) position. If one of the two connectors is not used, the termination switch will be in position T.

An incorrect setting of the link ends can lead to an erratic running of the system or impede its updating process.

By default, the termination is set to terminated (position T) on each Whisper Power product.

BLINKING CODES AND PUSH BUTTON

PUSH BUTTON

Key	Description
(a)	Push button (Not used / reserved for future use)
(b)	Bicolored signalization LED (green/red) The signalization LED

indicates different functions using color and frequency of blinking.
It is explained in chapter 5.1
(c)| WPC-CAN communication connectors These connectors allow the WPC-CAN to be connected with an WPC system.
This is the Whisper Power communication side of the device.
Do not connect your battery on it, neither any devices suited for standard Ethernet connection nor Whiz- per Connect devices.
(d)| Switch for communication line ending This switch activates or deactivates the communication bus termination.
The termination is by default activated (terminated).
In Figure 3, the termination is activated.
Place the switch to the correct side:
if there is only one cable connected on port c (com bus) put the switch in T (terminated) position.
If there are two cables connected on port c (WPC-CAN connected to two other devices) place the switch in position O (open).

Signalization LEDs

Bicolour LED	Meaning
Blinks 2x repeatedly in GREEN	The WPC-CAN is running without any

error.
Blinks 1x repeatedly in ORANGE| The WPC-CAN is currently starting up.
Blinks 2x repeatedly in RED| The WPC-CAN is in error. See chap. 6.

Elements on the external CAN bus side of the module

Key	Description
__ (e)	CAN connectors for an external network These connectors allow

the WPC-CAN to be connected to WhisperConnect.
The cable pinning must be carefully checked before connecting any device at this point. Do not connect any devices suited for standard Ethernet connection.
__ (f)| Switch for CAN termination This switch activates or deactivates the communication bus termination.
The switch is set to (O) in default. When only one cable is connected to port (E) add a WhisperConnect terminator.

TROUBLESHOOTING

There are different problems that may cause the WPC-CAN to malfunction. This list presents known irregularities and the procedures to follow to address them.

Symptom	Description
All LEDs are off	Your WPC-CAN is not powered correctly.Check that the module

is correctly connected to your WPC system with the appropriate cable. See chapter 5.4
Red LED blinking| An emergency stop occurred or the communication with the battery or third party device is lost. The RCC screen will help you find the source of the problem.
In case of an emergency stop:

Restart the battery system if it has stopped (switched off) or changed to limited power source (preload mode).
Check whether the battery is correctly connected with the WPC-CAN module.
Check that the CAN communication speed of the WPC-CAN module is corresponding to the one of the battery.
The communication speed is indicated on the RCC under the menu “System info”. Use the arrows to find and select the WPC-CAN.
Check that the jumpers are correctly positioned. See chap. 5.4
When the LED is blinking normally again (Blink 2x green), turn on the Whisper Power devices that were turned off by the emergency stop, one by one.

SOFTWARE UPDATES

In case of requirement of software upgrade of the system through the RCC unit, the WPC-CAN is automatically
upgraded. For more information visit our website www.whisperpower.com.

UPDATING PROCESS

Turn off all inverter units before making the update. If not manually done, the updating process will automatically stop all WPC connected to the communication bus.

To carry out an update, insert the micro SD card (containing the latest software version) in the RCC’s micro SD card reader. Before starting the updating process, the system automatically checks the compatibility between the devices and the software present on the micro SD card. The micro SD card must NOT BE REMOVED UNTIL THE END OF THE UPDATING PROCESS. IF FOR SOME REASON THE UPDATING PROCESS IS INTERRUPTED, REINSERT THE SD CARD TO LET THE PROCESS FINISH.

The updating process can take between 3 and 15 minutes. During this period, it is possible that the signalization LED does not respect exactly the cyclical ratio described.

The updating of a remote control RCC, WPC RS-232i must be done directly on the connected device.
