Safety Instructions

General Instructions

HAZARDOUS OPERATION

These devices must be installed, configured and used by qualified staff only.

Users must follow all current instructions, standards and regulations.

Check the function settings before starting the motor.

Do not downgrade or modify these devices.

Failure to follow these instructions can result in injury or equipment damage.

PRECAUTIONS WHEN USING COMMUNICATION VARIABLES

Only use the serial link for transmitting data that is not critical to the application.

There is some delay in the transmission of data relating to motor-starter states and load-current values. This data must not therefore be used in the management of safety devices and emergency stops.

Data such as Forward, Reverse and Stop must not be used in safety and emergency-stop circuits.

Failure to follow these instructions can result in injury or equipment damage.

CAUTION

Receiving the Product

On opening the box containing the LULC032-033 Modbus communication module, you should find the following items:

- An Instruction Sheet (IS), providing brief pictorial information about the standard installation of the module

- An LULC032-033 Modbus communication module with connectors.

NOTE: Check that you actually have all the items described above. Make sure that the Quick Reference Guide is included, along with the correctly inserted connectors.

Functions offered

The communication module is used to control a motor-starter remotely, via Modbus, from:

LULC032 LULC033

TeSys U starter-controller LUB••/LU2B••  TeSys U starter LUS••/LU2S••  TeSys U controller LUTM•• 

NOTE: Modbus LULC032 communication modules should be used exclusively with LUTM10BL or LUTM20BL controllers.

Using the communication module, you can:

 Read the motor-starter states  Control the motor-starter (reversing or non-reversing)  Adjust the protection functions  Read the data processed in the advanced and multifunction control units  Read the state of the I/O (controller base)

Installing the LULC032-033 Modbus Module

DANGER

CONTROL VOLTAGE

The LULC032 Modbus communication module must only be used with 24 V control units (LUC•••BL).

Failure to follow these instructions will result in death or serious injury.

NOTE: For information on the Modbus protocol, please refer to the following website: www.Modbus.org.

1743234 03/2009 13

Installing the LULC032-033 Modbus Module

Data Available

The available protection and control data depend on the control unit with which the Modbus communication module is used.

There are 3 types of control unit:

 Standard (reference LUCA)  Advanced (references LUCB/C/D, LUCBT/DT)  Multifunction (references LUCM/MT)

The table below can be used to check the data and commands you can access with each type of control unit:

Loss of communication on the Modbus network

NOTE: During startup, because the default fallback mode is "forced stop", if no communication has previously been established, the red "ERR" LED will flash after one minute (default timeout value).

Addressing Using Switches

The Modbus communication module address is defined by switches located on the underside of the module. Simply turn the module over to access them:

The range of accepted values is between 1 and 31.

The address coding is in binary format.

The least significant bit is on the right, indicated by .

Address 0 is not taken into account by the module, since it is used by the Master for a broadcast request.

Caution: Address selection differs from that on the LULC031 Modbus communication module.

NOTE: Addressing is only taken into account when the communication module is powered up.

Order of Mounting on a Base

The LULC032 module is installed in a controller base, the LULC033 module is installed in a power base or a controller base (on the underside of the control unit which locks it in position).

To install the module in the power base or controller base:

Step Action

1 Choose the prewired coil connection terminals.

2 Insert the LULC032-033 Modbus communication module.

3 Insert the control unit which locks the module.

The diagram below illustrates these steps. Installation of the LULC032-033 Modbus communication module corresponds to step (2). The numbers indicate both the order of mounting for the components and their location.

Power-up with an LUCM Multifunction Control Unit

LUCM and Power Base

The power-supply source must be the same for the LULC032-033 Modbus communication module and the LUCM multifunction control unit.

It is essential that the LUCM multifunction control unit and the LULC032-033 Modbus communication module are powered up simultaneously. Indeed, monitoring of the internal dialog between the LUCM and the LULC032-033 will produce two error messages depending on the order in which these objects were powered up.

When the A1-A2 terminals are not yet powered up (24V ), there are 3 possible scenarios for powering up the 24V Aux:

Comment

The "M15" fault is displayed. This only occurs when the LULC032-033 Modbus communication module has already been used with the LUCM multifunction control unit.

The LUCM control unit is identified by the LULC032-033 Modbus communication module when the 24 V Aux for the LULC032-033 Modbus communication module is switched on. If the 24 V Aux for the LUCM control unit is switched on for longer than twice the duration of the timeout (i.e., more than 1 s), the "M101" fault is displayed (register 451, communication module internal faults).

NOTE: Both these faults are reset by powering down and then powering up the LULC032-033 Modbus communication module (power cycle) and the LUCM control unit.

LUCM and Controller Base

The 24 V module power supply is provided by the LUTM controller.

Installing the LULC032-033 Modbus Module

Power Supply for the LULC032 and Outputs OA1, OA3 and LO1

In order to operate, the LULC032-033 Modbus communication module must be powered by a 24 V source:

 With a power base, the LULC033 must be powered by an external source.  With a controller base, the LULC032 or LULC033 is powered directly.

Power Supply for LUB••/LUS•• /LU2B••/LU2S•• Power Bases

1 24 V Aux: Power-supply terminal for the LULC033 Modbus communication module. 2 24 V ==: Power-supply terminal for outputs OA1 OA3 and LO1. 3 Prewired link for connecting outputs OA1 and OA3 to terminals A1/A3/A2 on the starter.

Power Supply for an LUTM Controller Base

1 24 V ==: Power-supply terminals for the LUTM and the LULC032-033 Modbus communication module via an

internal link.

2 The 24 V == power supply for the LULC032-033 Modbus communication module is only required when using

outputs OA1, OA3 and LO1.
