LED Indicator and GUI design Key Functions Phase 1 / 2 / 3 LEDs It informs you that voltage is taken from the phases. (e.g. LED L1 lights up if voltage is being taken from phase L1.
Measurement Voltage This screen shows the phase-neutral voltage values for each phase. You can see Min Voltage (Phase-Neutral) and Max Voltage (Phase-Neutral) values by pressing the OK button. Depending on the connection type in the Phase-Neutral voltage (3P3W, 3P3W balance and Aron), this screen will not be displayed. This screen shows the phase-phase voltage values for each phase. You can see Min Voltage (PhasePhase) and Max Voltage (Phase-Phase) values by pressing the OK button.
Current Instantly measured current values for each phase are displayed on this screen. You can see Min Voltage (Phase-Neutral), Max Current (Phase-Neutral), Demand (Phase-Neutral) and Max Demand (Phase-Neutral) values by pressing the OK button. Neutral Current This screen shows the calculated neutral current value. You can see the Min and Max values by pressing the OK button. Also depending on the connection type of the neutral current screen (3P3W, 3P3W balance and Aron), this screen will not appear.
Frequency You can see the operating frequency of the device on this screen. Cos Phi You can see cos phi values of each phase separately on this screen. Total Cos Phi You can see total cos phi values on this screen.
Total Run Hour It is the screen on which the run hour of this device is displayed. You can view the time it has worked since the first power-up on the screen. The value on the screen increases by 1 in 3.6 seconds. If you multiply the value on the screen by 3.6, you can reach the total operating time. Run Hour This screen works according to the condition of the parameters selected from the settings. It is the counter that will run when the parameters exceed the threshold value entered by the user.
Settings Press and hold OK to access the settings menu. If you wish to do something under the Settings menu or change the settings, press OK to go to menu details and change Product or User settings under the Settings menu. In the Settings menu, the symbols in the right corner of the screen indicate which setting you are in. User Settings It is the menu where you can set the Language for your device. You can use the up and down arrow buttons to choose between Turkish, English, German and French.
Password Setting On this screen, you can set the password that you will use for the security of the device. The current password is entered on the first screen. If it is entered correctly, the screen for entering the new password will be displayed. The screen for re-entering the password is displayed to confirm the new password. As with all settings, the saving confirmation must be set to yes when exiting the settings for the new password to be active.
Connection Type 16
Frequency Demand Period (Based on Model) 17
Voltage Transformer Setting In this screen, you can configure the voltage transformer settings. If you are using a voltage transformer, you must set the setting to on and then enter the primary and secondary values.
Current Transformer Setting It is the menu in which the primary and secondary values for the current transformer are entered. You will be prompted to enter CT Primary and CT Secondary values respectively. Communication Settings Communication and Modbus RTU settings of the device are made in this menu. Modbus address, bit rate, parity bit settings of the device are made in this menu (For models without communication, this screen will not be available).
Modbus Address: This parameter can be set to a value between 1 and 247. The value set must be unique on the line where the product is found. Otherwise, communication of the line, to which the product is connected, will be disrupted. Bit Rate: This parameter can be set to one of the following values: 2400, 4800, 9600, 19200, 38400, 57600, 115200 or 256000 bps. The value of this parameter must be the same as the value in the software you use to communicate with the product.
Output Settings On this screen, you can configure the output settings of the device. Relay 1 Press the OK button to configure the relay setting. Then select the setting parameter. Setting parameter can be selected as Relay or RS-485. If the setting is selected as a relay, the relay is activated when an alarm condition occurs (if the alarm output is assigned as a relay). If RS-485 is selected, the relay can be switched on and off via MODBUS.
Alarm Settings User Mode It is the screen where the user mode is selected. The user mode can be selected as simple or advanced. In the advanced user mode, the following parameters are activated (varies by parameter). Hysteresis is only available in the measurement parameters. • • • • Ton Toff Hysteresis Output function Press the OK button to enter the alarm settings.
Custom alarm Press the OK button to program a custom alarm. Then select a parameter. Parameter selection varies by device model. You can set alarm by selecting Voltage, Current, Current demand, Frequency, Cos Phi, Total work time and work time. For example, the voltage alarm setup is as follows.
Press the OK button to make an operation selection. Select the large or small operation. Then press the OK button and enter a value.
Enter the hysteresis value and press the OK button. Enter the on delay and press the OK button. Enter the off delay and press the OK button.
Select the output feature on the device with output options. When this option is selected, there is no output on the device. When Rly 2 is selected, relay number 2 is activated in case of alarm. When Rly 1 is selected, relay number 1 is activated in case of alarm.
Press the OK button to select the function. In standard mode, the relay is activated when an alarm occurs. In Latch mode, the relay is activated when the alarm actuates, but when the alarm disappears, the relay remains on. You must hold the down button to return the relay to its normal state. In Inverse mode, the relay is released if it is activated, or it is activated if it is released.
Reset On this screen, you can reset the device to factory settings by pressing the OK button. On this screen, you can reset the work time by pressing the OK button. On this screen, you can reset the MAX Demand by pressing the OK button. On this screen, you can reset the MAX by pressing the OK button.
On this screen, you can reset the MIN by pressing the OK button. On this screen, you can reset the work time by pressing the OK button. The total work time cannot be reset. Info In the Info menu, you can view the following information about the device.
Software Version Serial No Run Hour In this menu, you can set the work time for Current or Current Demand.
Alarm Messages When an alarm occurs on your device, the alarm appears on the screen. You can delay the alarms by pressing the OK button for the duration of the delay time setting. When critical alarms occur, Relay 1 is activated. No Voltage is measured It occurs when any phase has no voltage. The number of the voltage-free phase is shown on the screen. In addition, the bulb of the voltage-free phase in the signal bulbs does not light upon the device.
Phase Sequence It occurs when the phases are not connected in the correct order. Custom Alarm It appears on the screen when any of 8 special alarms actuate. The alarm number is displayed on the screen.
