Control functions of PAC-E500 also provide a local/remote selection for control location. As for remote control, PAC-E500 communicates with an upper master system (SCADA) through the rear RS485 port (Protocol: Modbus). To control CB, a contact input should be allocated for CB STATUS input (CB_OPENED or CB_CLOSED). If there are many contact inputs allocated for CB status, “Contact Input #1” status is the first priority for CB control. In case no contact input is allocated for CB status, CB control function is not available and all LEDs related to CB control (Local/Remote, Open/Close) are off. Local / Remote (L/R) Control Position To control the circuit breaker, the operator must get the appropriate right to control. The Local/Remote button renders CB control right to the local operators on site or to the remote operators in control center. Remote operator cannot control CB on the local mode, and vice versa. Security check by password inhibits the random mode change. To change the control position mode (Local to Remote and Remote to Local), press L/R button and enter the password using arrow keys and ENT key. After correct password input, local and remote control positions can be toggled. CB OPEN / CLOSE This function performs trip (open)/close control actions of CB. CB Open or Close button on the front panel is activated only on the Local mode (“L” LED on). On the Remote mode, only control command from SCADA through communication is accepted. Before control command via front panel, SELECT button and Password enter are required first. SELECT button is the concept to prevent the mal-operation on the front panel and this concept is the same with SBO (Select Before Operate) concept in communication protocol, i.e. DNP3.0, where SCADA (master system) selects first the equipment to control remotely before setting out actual control command to keep other masters from selecting the same equipment so that control right is granted to that SCADA only. This dedicated concept is adopted equally to Local control and this is also used for mal-operation prevention of direct open/close command. After the correct password enter and SELECT button again, then a phrase that CB is selected is displayed on LCD and SELECT LED is blinking. After while, CB OPEN/CLOSE buttons are activated for 15 seconds. 18/76 Over Voltage & Under Voltage Relay (PAC-E500) User’s Manual 3.2.2 Measurement & Metering Current Voltage Frequency Sequence RMS Current value of fundamental component & phase angle of A-phase Range: 0.01 ~ 50 * In RMS Measuring accuracy: 2 (0.10 ~ 0.20 * In) 0.5 (0.20 ~ 1.20 * In) ±1.0 % (＞1.20 * In) RMS Voltage value of fundamental component & phase angle per phase and line-to-line Metering range: 2.00~999.99V (Phase voltage) 2.00~999.99V (line-to-line voltage) Measured based on A-phase voltage Metering range: 40 ~ 70 Hz Measuring Accuracy: 0.03 Hz Positive, Negative, Zero Sequence Values of Current 3.2.3 Programmable Logic Input Logic Reset Type Reset Delay Feature CB Open/Close control, Protection element is pickup, Self-diagnosis, Contact Input OR8 (8 input OR) HALF-OR8 (Non inverting 4 input & inverting 4 input OR) AND8 (8 input AND) HALF-AND8 (Non inverting 4 input & inverting 4 input AND) Self (latched until delay timer is expired) Manual (latched until annunciator reset is issued) 0.00 ~ 60.00 sec (0.01 sec step) Control contact output and LED using Logic Input#1 Input#2 Input#3 Input#4 Input#5 Input#6 Input#7 Input#8 Reset Type = Self Input#1 Input#2 Input#3 Input#4 Input#5 Input#6 Input#7 Input#8 0.00 ~ 60.00 LED#1~#4 Reset Type = Manual Input#1 Input#2 Input#3 Input#4 Input#5 Input#6 Input#7 Input#8 S Q Input#1 Input#2 Input#3 Input#4 Input#5 Input#6 Input#7 Input#8 R Logic Annunciator <Figure 3.2.3.
