4. סעטאַפּ און ייַנמאָנטירונג
Follow these general steps for installing the EOCR-FEZ Motor Protector:
- מאָונטינג: Securely mount the EOCR-FEZ unit within your control panel using appropriate fasteners.
- מאַכט קשר: Connect the main power supply to the designated terminals (e.g., A1(+), A2) as per the wiring diagram provided with your specific motor setup.
- קראַנט טראַנספאָרמאַטאָר (CT) פֿאַרבינדונג: Connect the current transformers (ZCT) to terminals Z1 and Z2. Ensure correct polarity for accurate current sensing.
- Output Relay Connections: Connect the overload/underload (OL/UL) relay contacts (97, 98) and ground fault (GR) contacts (57, 58) to your control circuit as required for alarm or trip functions.
- Display/Communication: If an external display or communication module is used, connect it to the multi-pin port on the unit.
- וועראַפאַקיישאַן: Double-check all wiring connections for correctness and security before applying power.
5. אַפּערייטינג ינסטרוקטיאָנס
Once installed and powered, the EOCR-FEZ operates by continuously monitoring the motor's electrical parameters. The split screen (if connected) will display real-time data such as current, voltagע, און אפעראציאנעלער סטאטוס.
- מאָניטאָרינג: Observe the display for normal operating parameters. Any deviations may indicate a potential issue.
- Alarm/Trip Indication: The device will activate its output relays (OL/UL, GR) and provide visual indicators (if available) upon detecting an abnormal condition (e.g., overload, underload, ground fault).
- רעסעטטינג: After a trip event, identify and resolve the root cause. The device can typically be reset manually or automatically depending on configuration. Refer to the detailed programming manual for specific reset procedures.
