Binary Input Setting, Part2
“Reverse” column: In "False" mode in the "Reverse" column, the logic of binary’s becoming 0 and 1 is the same as described earlier. If the "True" mode is selected, the detection logic of the binary's becoming 1 is reversed. For example, in the "Wet Max 188(V)" level with a 50V threshold, if the binary voltage goes below 50V, its status is detected as 1, otherwise, it equals 0. In the "Dry", the "Binary Input" status is 1 only when it's "Open Circuit" and it's 0 in the short circuit state.
The “Show Actual Value” column: In the "Show Actual Value" column, the mode of displaying the actual voltage value of the input binary is selected from "AC" and "DC". The "DC" mode is used for situations where the input voltage of the "Binary Input" is "DC". The "AC" mode, on the other hand, is for situations where the incoming voltage to the "Binary Input" is "AC". In this case, this is done for a better display and precision of the phase calibration and frequency. "None" mode is used for not displaying the actual value of the binaries. To view the actual value in the "Vector View", it is possible to view the measured value by the binary after opening this window.
“Show Result” column: In the “Show Result” column, it is specified that whether the changes of the 1 and 0 logical signals of the “Binary Input” should be recorded by the software or not. “True” means that the logical signal should be recorded and “False” means the opposite. For example with 50 voltage threshold and “False” for “Show Result” and “Reverse” the trip signal is sent by the relay to the device. As signal of binary input 1 excess the threshold the binary changes are not recorded by “signal view” becqause the signals are not being recorded
DC Voltage Injection: In the "Apply VDC" column, it is possible to inject a DC voltage into the binary input. For example, in the "Wet Max 188(V)" with a 50V threshold, the number 100V is entered and subsequently the wiring to inject the DC voltage into the binary input is displayed. According to this wiring, the output relay contact is switched to "Wet". In this case, if the input voltage of the binary exceeds 50V, the "Binary Input" equals 1. It should be noted that it is possible to inject DC voltage only into one "Binary Input" and not into multiple Binary Inputs simultaneously. If for any reason, the output relay contact is corrupted, it may not get stimulated by the 2V on the "Binary Input" of the device; so a, for example, 100V DC is injected into it. In this case, a mild current passes through the relay contact and its short-circuiting is detected.
The “Description” column: In this column, there is some information about the condition where the binary input of the device equals 1. For example, in the “Wet Max 188(V)” with a 50V threshold, when the input voltage exceeds 50V, the binary status equals 1.
Configuration of the Binary Input 9 and 10: As mentioned before, "Input" 9 is used for measuring currents up to 500mA and "Input" 10 is used for measuring Voltages up to 240mV. The columns "Show Result", "Reverse", "Threshold", Apply VDC" and "Description" are disabled for these two binaries. In the "Binary Input Type" column, the precision of "Input" 9 is set. On the back of this binary, there are four 1ohm, 20ohm, 100ohm and 1megaohm resistors which are used to measure the current in different ranges. By selecting any of these resistors in the "Binary Input Type" column, the 500mV voltage is divided into the resistor and the measurable current is calculated by the binary. It is, also, possible to display the actual measured current and voltage value in “DC” or “AC” in the “Show Actual Value” column.
