3.7 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 selectable with Jumper J1001.
3.8 RS232 PORT (KM1009)
The RS232 Port can be used for software download using a batch file in DOS window. Upgrades
can also be performed through this port but by ABB factory only.
3.9 JTAG COMMUNICATION PORT (KM1008)
The JTAG Communication Port can be used for software upgrades also. Additionally, it can be
used for software debug and software checksum using a JTAG Emulator Interface and code
compose development tool by Texas Instruments. It can be used by ABB factory only.
4.0 BINARY INPUTS
Binary input channels work properly with a voltage range of 24 to 264 VAC/DC regardless of
which board is used. All inputs have a low threshold at about 18 VDC and 19 VAC with the
exception of the Protection Relay input, which has a low threshold of about 7 VDC. To avoid
false triggering by noise, the inputs must be active for at least 10 milliseconds. A Fast Input
mode is available so that the input can be selected after only 2 milliseconds. Choosing the
Fast Input mode may make the board more sensitive to nuisance opening or closing
operations. The current draw for most inputs is < 2 milliamperes. The exception is the Remote
Open and Close inputs, which draw up to approximately 20 milliamperes. The input
impedance (Z) is 300 kOhms except for binary inputs 1 and 2 (Remote open and close) which
are around 14 kOhms input Z.
There are seven different input channels. Only six of them are used for our products: 1)
Remote Open, 2) Remote Close, 3) Auxiliary/Safe Open, 4) Protection Trip/2nd Trip, 5) Circuit
Breaker locked open, 6) Under Voltage Input. Input channels 2 and 3 are broken out in the list
below because they each have two programmable functions.
4.1 REMOTE OPEN (KM1005 Pins 1 and 2)
The Remote Open input is used to trip breaker remotely. The input impedance is approximately
14 kOhms.
4.2 REMOTE CLOSE (KM1005 Pins 3 and 4)
The Remote Close input is used to close the breaker remotely. The input impedance is
approximately 14 kOhms.
