3.SETTINGS

This section describes the settings of the DBF relay and the procedure to modify them. Table 3 shows the list of DBF settings, their range and resolution, and the factory default settings.

To view or to modify settings using the GE_LOCAL program connected to PORT 1, PORT 2 or PORT 3 the user has to perform the following steps:

∙Check that the available connection cable is in accordance with the diagram in Figure 7. Check correspondence between DB-9 connector in the cable with available connector at PC port (could be DB-9 or DB-25)

∙Connect the cable between the relay (or modem) and the serial port of your computer.

∙Run the GE-LOCAL software. For more details on the installation and use of the GE-LOCAL software see instruction book GEK-105568.

∙Make sure that the communication parameters in GE_LOCAL match with those set on the DBF. Specifically, the parameters on the configuration of the local HMI are:

∗COMMUNICATION SPEED: On the relay depending on whether communication is: through PORT 1 or PORT 2 (means LOCAL), or PORT 3 (means NET)

∗STOP BIT: Stop-bit corresponding to each one of the communication ways: LOCAL or

NET

To modify or view the DBF communication parameters refer to Chapter 8, Section 8.1 “Menu Tree”.

IMPORTANT: It should be noted that in order to simplify the setting of the unit and for safety reasons, all settings related with the configuration of the unit (configurable inputs and outputs, internal status events and target LED’s) have been removed from the HMI facilities and also from the communications software GE_LOCAL. To perform these configurations the GE_INTRO software (described in instruction book GEK-105569) must be used.
