Fault Cause Remedy

Controller is switched off.

Display:

• none of the operating-state displays is lit-up

and/or

• green Vcc-LED is blinking

Supply controller with voltage (see corresponding Operating Instructions)

2102IB fie ldbus module is not supplied with voltage

Display:

green Vcc-LED is not flashing or blinking.

• With internal supply from the controller, check the connection to the

controller.

• With external supply, check the voltage at terminals 39 and 59.

A voltage between 15 and 30 V must be applied (see chapter 4.3)

The 2102IB f ie ldbus module has not been initialized with the controller

Display:

green Vcc-LED is blinking.

• Supply controller with voltage (see corresponding Operating

Instructions)

• Check the connection to the controller .

communication

with the

controller.

The controller does not receive telegrams.

For a test, let the host send telegram cyclically. This happens, for

instance, with LEMOC2 in online operation.

The yellow RxD-LED must blink when the host sends a telegram.

If the yellow RxD-LED does not blink:

• Check the wiring (see chapter 4.4)

and

• T est whether the host sends telegrams and uses the appropriate

interface.

The controller does not send telegrams.

For a test, let the host send telegram cyclically. This happens, for

instance, with LEMOC2 in online operation.

The yellow TxD-LED must blink when the controller send a telegram to

the host.

1. Yellow TxD-LED is not blinking:

Parameter for LECOM unit address (C0009) and LECOM baud rate

(C0125) must be the same at t he controller and the host. Check t he

parameters C0009 and C0125 at both units and set them to the same

value if necessary.(Controller-address parameters 00, 10,

¼,90must

not be used.)

2. Yellow TxD-LED is blinking:

• The LECOM unit addresses (C0009) must be different at all

connected controllers. Correct possibly occurring double addressing.

• Check the wiring to your host.

• With self-developed LECOM-A/B software drivers and RS485

operation, observe the transmission control. After transmitting

signals, the host must return to receive mode after approx. 1 ms.

Controller does

1. Controller sends negative acknowledgement (NAK response):

not execute

write job

• The o perating mode C0001 is set incorrectly for write access to

codes C0046 a nd C0135.

• S et paramet e r 3 for operating mode C0001.

• The code is defined so that it can only be read. • In general, write job not possible.

2. Controller sends positive acknowledgement (ACK response):

• With 820X, parameters can only be changed when t he controller is

inhibited (see chapter 6.3).

• Activate controller inhibit

• Controller uses a different parameter set • Changeover of the parameter set; the parameter change is then

activated.
