1. Chigadzirwa Pamusoroview
The Generic EAPDX-3P is a three-phase relay designed for comprehensive protection of electrical systems. It monitors voltage and current across three phases (L1, L2, L3) and provides protection against over current, over voltage, uye pasi pevoltage conditions. This device is available in 63A and 100A variants, offering adjustable protection settings to suit various industrial and commercial applications.
Mufananidzo 1: Mberi view of the EAPDX-3P Three Phase Relay, showing the digital display for voltage (V) and current (A) across phases L1, L2, L3, along with control buttons (SET, Up, Down, Power) and status indicators.
2. Setup uye Kuiswa
Chengetedzo Kutanga: Before installation, ensure that the main power supply is disconnected to prevent electrical shock. Installation should only be performed by qualified personnel in accordance with local electrical codes and regulations.
2.1 Kuiswa
The EAPDX-3P relay is designed for DIN rail mounting. Securely attach the device to a standard DIN rail within an appropriate electrical enclosure.
2.2 Wiring
Connect the three-phase power lines (L1, L2, L3) and the neutral line (N) to the corresponding terminals on the relay. Ensure all connections are tight and secure to prevent loose contacts and overheating. Refer to the wiring diagram provided with the product packaging for specific terminal assignments.
3. Operating Instructions
Upon power-up, the relay's digital display will show the current voltage and current values for each phase (L1, L2, L3). The device features a 'SET' button and navigation buttons for configuring protection parameters.
3.1 Ratidza Dudziro
- V (Voltage): Inoratidza voltage for each phase (L1, L2, L3).
- A (Current): Displays the current for each phase (L1, L2, L3).
- Power >V <V >I: Indicators for over voltage, pasi pe voltage, and over current conditions.
- Synchronous/Asynchronous: Indicates the operating mode for protection.
3.2 Kuisa Parameters
Press the SET button to enter the parameter setting mode. Use the Up uye Pasi buttons to navigate through different settings and adjust values. Press SET again to confirm a selection or move to the next parameter. The device will automatically save settings after a period of inactivity or upon exiting the setting mode.
- Over Current Protection Setting Range: Adjust the maximum allowable current.
- Continuous Over Current Protection Times: Set the number of times over current can occur before tripping.
- Kupfuura Voltage Protection Setting Range: Define the upper voltage limit.
- Kupfuura Voltage Protection Recover Setting Range: Seta vhoriyamutage at which the relay will automatically reset after an over voltage chiitiko.
- Pasi peVoltage Protection Setting Range: Define the lower voltage limit.
- Pasi peVoltage Protection Recover Setting Range: Seta vhoriyamutage at which the relay will automatically reset after an under voltage chiitiko.
- Voltage & Current Protection Recover Delay: Configure the delay time before the relay recovers from a protection event.

5. Kuchengeta
The EAPDX-3P relay is designed for reliable operation with minimal maintenance. Periodically inspect the device and its connections for any signs of wear, damage, or loose wiring. Ensure the ventilation openings (if any) are clear of dust and debris. Clean the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
6. Kugadzirisa matambudziko
- Mudziyo hausi kubatika: Check the main power supply and ensure all wiring connections are secure. Verify the rated supply voltage inofanana nezvinodiwa zvechigadzirwa.
- Relay tripping unexpectedly: Review the set protection parameters (over current, over voltage, pasi pe voltage) to ensure they are appropriate for your application. Check for actual fault conditions in the electrical system.
- Display not showing correct values: Ensure proper wiring of all three phases and neutral. If the issue persists, contact support.
- Unable to change settings: Ensure you are in the parameter setting mode by pressing the SET button. If the buttons are unresponsive, power cycle the device.
For issues not covered here, or if troubleshooting steps do not resolve the problem, please contact the manufacturer or seller for assistance.
