WARNING

Improper communication port usage

Use communication ports for transfer of non-critical data only,

•

The data provided by monotoring contactor status and current levels is delayed by transmission time. Do not use this data for critical control decisions.

•

Verify function settings before starting the motor.

•

Do not use functions such as Run, Stop and Reverse for emergency or critical control applications.

Improper use of Communication Ports can result in death, serious injury, or equipment damage.

When combined with the LUCM multifunction control unit, you must ensure that you do not supply 24V DC power to the to LUCM control unit. Otherwise, a communication fault will be generated at the

5-2-2 Contingency modes if communication with the PLC is lost

The following commands only affect the operation of OA1 and OA3 modes if communication with the PLC is lost.

These contingency modes are selected by writing 1 in the bits of register 682 according to the following allocation:

Without contingency mode:

- Value 0 ==> Contingency mode disabled (default setting),

With contingency mode:

- Value 1 ==> Held in same state (outputs OA1 and OA3 remain in the same state as before

- Value 2 ==> Forced stop,

- Value 3 ==> Unchanged (signals a Time Out fault, the command states in register 704 are

- Value 4 ==> forced running in direction 1 (OA1 output = 1 and OA3 output = 0),

- Value 5 ==> forced running in direction 2 (OA3 output = 1 and OA1 output = 0).

ENGLISH

5-2-3 Command for the programmable output LO1

It is possible to allocate a “default” command to the digital output of the LULC031 module. This provides a ‘fault “ output on the communication module. This is allocated by writing 1 to the bits in register 685.

- Value 0 ==> LO1 port always on 0 (zero),

- Value 1 ==> LO1 port always on 0 1,

- Value 2 ==> No allocation, output LO1 is not used,

- Value 3 ==> A thermal overload fault will cause output LO1 to close (452.3 = 1)

- Value 4 ==> A thermal overload warning will cause output LO1 to close

- Value 5 ==>

- Value 6 ==> The mechanical system tripping (rotary button set to the “Trip” position) due to

- Value 7 ==> Close down of the power Base poles will cause output LO1 to close (457.2 = 1).

5-2-4 The registers

The number and content of the registers that can be accessed differs according to the type of control unit to which the module is associated.

copied to outputs OA1 and OA3),

Rotary button set to the “ready” position will cause output LO1 to close (457.0 = 1).

an over-current or short-circuit fault will set output LO1 to 1

(461.3 = 1).

(457.1 = 1)

5-2-4-1 The read/write zones

The memory zone from 0 to 19999 can be accessed by the client.

- Reading the zone of a "Reserved" register (or non-set) causes a correct response (value "0").

- Writing to the zone of a "Reserved" register causes a correct response (value "0").

NOTE: The write operation is not taken into account and the contents remain equal to (0).

- Writing to the zone of a "Read only" register causes a response with an exception code (code 03).

The memory zone = 20000 is private and therefore reading/writing is not authorised.

NOTE: All accesses will be signalled by an exception code (code 02).

This control unit satisfies the strictest motor protection requirements.

These protection systems can be adjusted and configured locally via a display/keypad that is incorporated on the front panel and remotely by reading/writing to registers. It processes the following information:

- diagnostics (type of faults, current values,…)

- operating (number of starts, operating time, number and type of trips,…)

- fault log (record the last 5 faults with the motor current at the moment the fault occurred)

This information is provided in registers, the summary of which is the following (for more details, see the user’s manual for the multifunction control unit).

This action results in the restitution of the LULC031 module’s default settings (factory settings) in respect of the following parameters :

- Bus speed and parity,

- Setting registers 681 to 690
