3.1 SETTINGS
This section describes the settings incorporated in the DTR system, and the procedure for changing them. First a
complete list of the DTR settings is shown, together with their limits, units and corresponding steps (the column
marked DEFAULT indicates that this is the setting on the relay when it leaves the factory). This is followed by
individual comments for those settings that require more detailed explanation.
It is possible to see the settings or to modify them manually, using the keyboard and display, or by means of a
computer connected to any of the serial ports. To modify the settings by computer follow these instructions:
•
Make sure that the available connection cable coincides with the diagram in figures 4 and 5, depending on if the
serial port of your computer is DB9 or DB25.
•
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 software see the GE_LOCAL
instruction book.
•
Make sure that the program configuration communication parameters coincide with those of the DTR unit. More
specifically, these parameters for the communication of the local HMI are as follows:
- COMMUNICATION BAUDRATE (for the relay depending on which port is being used: local or remote)
-
STOP BITS (for the relay depending on which port is being used: local or remote)
To modify or view the unit’s configuration parameters go to the configuration menu, corresponding to section 8
“KEYBOARD AND DISPLAY”
When connecting to the unit, check that the relay number and password coincide with those which appear on the
unit’s configuration menu.
The DTR system has 3 settings tables stored in non-volatile memory (EEPROM), and these can be selected by
setting or configurable inputs. There is also a set of independent settings, common to all the tables. The following
category contain the settings common to the 3 tables:
GENERAL SETTINGS
The remaining categories, shown below, contain the settings which can be selected independently for each of the 3
tables:
REGULATION SETTINGS
BLOCK SETTINGS
TIMERS
VOLTAGE SETPOINT
It should be noted that in order to simplify settings the unit and for safety reasons, all settings related to the
configuration of the unit (configurable inputs and outputs, alarms, events, etc.) have been removed from the
keyboard / display and communication software. To carry out these configurations the GE_INTRO configuration
software must be run (refer to GEK-105569 for further information).
