Installation

Unpack and verify all components. Mount on a secure, vibration-free surface.

Connect Power: Attach appropriate gauge wires to the power terminal block (L, N, PE).
Connect Data/Control Cables: Use RS-485 port for network; analog jacks for sensors.
Connect Peripheral Devices: Attach any authorized auxiliary equipment to designated ports.
Secure all connections and apply main power.

WARNING! Unit contains high voltage. Installation must be performed by qualified personnel. Ensure all connections are secure and properly insulated.

First-Time Setup

Apply power; the status LED will illuminate. Follow initialization sequence.

Select Operating Language: Use the MODE SELECTOR and CALIBRATE button to cycle through options on the display. Default is ENGLISH.
Run Self-Test: Hold CALIBRATE for 5 seconds to initiate system diagnostics.
Configure Basic Parameters: Navigate the setup menu to set units, communication address, and default mode.
Perform Initial Calibration: Follow on-screen prompts with no load connected.

CAUTION! Do not bypass the self-test. Ensure the work area is clear before applying full power.

Connecting Devices

Power: Terminal block (L, N, PE). Data: RS-485 (A+, B-). Sensors: Analog Input jacks (1-4).

Ensure the G 3025 and all devices are powered OFF.
Connect wires to the correct terminals, observing polarity for analog/digital signals.
Use shielded cables for analog signals and ground the shield at one end only.
Power on the G 3025 first, then peripheral devices.
Select the correct input source via the MODE or CONFIG menu.

Tip: Label all cables during installation for easier maintenance and troubleshooting.

Operating Modes

Supports Manual control, Automatic sequence, and User-defined Programs.

Select Mode: Use MODE SELECTOR button or remote.
Manual Mode: Direct control of outputs via front panel or interface.
Automatic Mode: Unit follows a pre-defined sequence based on input thresholds.
Program Mode: Execute stored user programs (up to 10). Load via menu.
Start/Stop Cycle: Press the dedicated RUN/HOLD button. The HOLD state pauses the sequence.
Monitor Values: Real-time input values and output status are shown on the display.
Override: In Automatic mode, a manual override is available for 30 seconds before reverting.
Data Logging: The last 100 fault events and operational parameters are stored in memory.

WARNING! Do not switch modes while an active cycle is running. Pause or stop the cycle first to prevent unexpected behavior.

Safety Features

Emergency Stop: Immediate hardware cutoff. Fault Monitoring: Continuous monitoring for over-current, over-temperature, and signal loss. Password Protection: Access to critical settings requires password (default: 0000). Safe Start: System checks for faults before initiating any cycle.

Care & Maintenance

Disconnect from mains power before any maintenance. Use a soft, dry cloth to clean the exterior. Do not use solvents or abrasive cleaners. Periodically check terminal tightness (with power off).

CAUTION! There are no user-serviceable parts inside. Do not open the casing. Internal maintenance must be performed by authorized service personnel only.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power / LEDs off	Power supply / Fuse	Check mains outlet and power cable. Verify internal fuse (see service manual).
'Fault' LED illuminated	Overload / Sensor error	Check connected load. Verify sensor connections and input signals are within range.
No communication with host	Wiring / Settings	Verify RS-485 wiring (A+, B-). Check baud rate and device address in configuration menu.
Inaccurate readings	Calibration drift	Perform zero and span calibration for the affected input channel.
Unit does not start cycle	Interlock / Safety	Check that all safety interlocks are closed. Ensure no active fault conditions exist.

Reset: System > Factory Reset (requires password). Note: This clears all user settings.

Service: Contact authorized Eurotops service center. Do not attempt internal repairs.
