6. UNIT CONFIGURATION
6-2 DTP-B Digital Transformer Protection GEK-106243E
6.2 OUTPUTS CONFIGURATION
The DTP system has 8 user configurable outputs, and 5 non-programmable outputs. The configurable outputs are
identified in the external connections diagram (figure 1) as SP1, SP2, etc. Any internal protection state shown in
TABLE II can be assigned to a programmable output, as well as the activation or deactivation of an internal state.
Also, AND and OR logics can be performed with the outputs.
For example, if we want to configure protection output 4 to the logic AND of input 3 and the 87B A TRIP, we will
follow these steps:
•
In the output ANDs screen, we configure AND1 to the INPUT3 activation.
•
In this same screen, we configure AND2 to 87B A TRIP.
•
In this same screen, we configure AND3 as the logic AND for AND1 and AND2.
•
In the output configuration screen, we configure SP4 output to the activation of AND3.
6.3 LEDS CONFIGURATION
The DTP unit has a total of 16 configurable LEDs. These can be associated to the internal protection and
communication states. A LED can be configured to blink, or to remain lit up when activated. Similarly, the user can
select whether he/she wants the LED to be memorized in the absence of the activation condition.
For configuring a LED, it is first necessary to associate an internal state to a protection or communication event.
Once this step is completed, the LED is associated to an event.
For example, if we want LED12 to light up when the A differential function trips, we will follow these steps:
•
In the PROTECTION EVENT ASSIGNATION menu, we associate “Protection Event 1” to “Differential A Trip”.
•
In the LED assignation menu, we will associate LED12 to “Protection Event 1”.
