5.0 FEATURES
5.1 Temperature Protection
The Temperature Protection circuit monitors the average temperature of a critical area on the
ED2.0 power supply. The output power will be linearly reduced to zero as the temperature
increases from 78 degrees C to 95 degrees C.
5.2 Actuator Close and Trip Coil Continuity Monitor
See Illustration 10 - Troubleshooting Guide.
5.3 Wrong Position Auto Trip
An Auto Trip command will be issued in the event the breaker does not perform a successful
close operation within 95 milliseconds after the close command is issued.
5.4 Energy Failure Auto Trip
The Energy Failure Auto Trip function is selected by Dip Switch I1004-1 and will cause the break-
er to auto trip in the event the capacitor voltage falls below 49 volts. Necessary precautions must
be taken when power is removed (e.g., power removed for maintenance) as the breaker will
automatically trip if I1004-1 is in the “On” position.
5.5 Reduced Power Consumption
The Reduced Power Consumption setting will lower the power output of the power supply
recharge unit, on the ED2.0 board, from 75 W power to 33 W. This enables the ED2.0 board to
be supplied with the energy delivered by a voltage transformer if necessary. The Power Supply
Recharge Unit is 80% efficient. This means that the Auxiliary Power supply input must be at least
93.75 W for the 75 W setting or 41.3 W for the 33 W setting. The 33 W option is hardware selec-
table with Jumper JP1019.
5.6 RS-232 Port / JTAG Communication Port
Used by ABB factory only.
CAUTION
If power is removed from unit, and the Dip Switch I1004-1 is placed in the “on”
position, the breaker will automatically trip in approximately 3 minutes. Make
sure personnel and tools are clear from breaker.
