Pre-Installation Checklist

Unpack and verify all components. Ensure installation site meets requirements.

Verify contents: Display unit, mounting bracket kit, communication cables, power supply (if not using PoE), hex key set, sealing gaskets.
Site preparation: Ensure mounting surface can support 25 kg (55 lbs). Check for access to power and data conduits.
Environmental check: Confirm ambient temperature within operating range. Ensure location is within IP65 rating limits (not submerged).
Tool readiness: Have appropriate tools (drill, screwdrivers, torque wrench, cable crimpers).

WARNING! Unit is heavy and contains glass. Use appropriate lifting equipment and personal protective equipment (PPE) during handling.

Mounting & Hardware

Follow these steps to securely mount the GFS-32-EXP display.

Mount bracket assembly: Attach the universal bracket to the rear VESA 400x400 pattern using the provided M8 bolts. Torque to 2.5 N·m (22 in-lb).
Positioning: For pole mount, use the supplied U-bolt kit. For wall mount, use the anchor points on the bracket. Ensure unit is level.
Secure the display: Lift the display onto the mounted bracket. Engage the locking latch. Secure with the safety lock screw.
Sealing: Before final closure, ensure the main cable gland and all port covers have their rubber gaskets properly seated.

CAUTION! Do not overtighten bolts on the enclosure. Use a calibrated torque wrench. Ensure the unit is mounted in a location that allows for adequate airflow around the vents.

Electrical Connections

Primary Power (Option A - PoE+): Connect a Cat5e or better cable from a 802.3at PoE+ switch/injector to the RJ45 port labeled "PoE IN".
Primary Power (Option B - 24VDC): Connect 24VDC (±10%) to the terminal block (TB1: +24V, GND). Use 16 AWG wire minimum. Install an external 5A fuse.
Alarm Outputs: Connect relay outputs (TB2: COM, NO, NC) to external alarms, lights, or PLCs. Maximum rating: 250VAC/5A per relay.
Sensor Power: The 12VDC/1A auxiliary output (TB3) can power external sensors.
Grounding: Connect the chassis ground lug to a verified earth ground using 12 AWG wire.

WARNING! All electrical work must be performed by a qualified electrician with power disconnected. Verify polarity on DC connections. Ensure all conduit entries are properly sealed to maintain IP65 rating.

Network & Communication Setup

Configure the unit for data communication and remote access.

Default Network: Unit boots with DHCP enabled. Check your router for its assigned IP address.
Static IP (Recommended): Access the web interface (default IP 192.168.1.100 if DHCP fails). Navigate to Network > Settings to set a static IP, subnet, and gateway.
RS-485 Configuration: Connect sensors to the A/B terminals on TB4. Set baud rate (9600-115200), parity, and Modbus address via the Configuration Menu > Communication.
Data Destination: Configure the IP address of your SCADA server, data logger, or FTP server under Data > Forwarding.

Tip: Label all cables at both ends. Use shielded cable for RS-485 runs and ground the shield at one end only.

Initial Power-Up & Configuration

Power on the system and perform basic configuration.

Apply Power: Switch on the 24VDC supply or ensure PoE+ switch is active. The power LED on the front should illuminate green.
Initial Boot: The GFS logo will appear. The system performs a self-test (approx. 60 seconds).
Access Menu: Press and release the sealed joystick on the lower right side to enter the main menu.
Basic Setup:
- Set Date/Time (Menu > System > Time).
- Configure Display Brightness & Sleep Schedule (Menu > Display).
- Set Measurement Units (Metric/Imperial) (Menu > System > Units).
- Create user passwords for menu and web access (Menu > Security).

NOTE: The default login for the web interface is admin / gfs32exp. Change this immediately.

Sensor Integration

Connect and configure environmental sensors.

Wiring: Connect sensor outputs to the appropriate terminals on TB5-TB8 (Analog Inputs 1-8). Refer to sensor datasheet for wiring (typically 2-wire for 4-20mA, 3-wire for 0-10V).
Software Configuration: For each sensor input (Menu > Sensors > Input 1):
- Select Type: 4-20mA, 0-10V, Digital, etc.
- Enter Scaling: Map the electrical signal to engineering units (e.g., 4mA = 0°C, 20mA = 100°C).
- Set Alarm Limits: High, Low, and Deadband values for triggering relay outputs.
- Assign a Label: e.g., "Ambient Temp - North Side".
Calibration: Use the on-screen calibration wizard for critical measurements after sensors have stabilized.

WARNING! Ensure sensor loop is powered down before making connections. Verify sensor output range is compatible with the selected input type to avoid damage.

Display & Interface Operation

Navigating the display and viewing data.

Front Panel Joystick: Press to enter menu. Move Up/Down/Left/Right to navigate. Press to select. Hold for 3 seconds to exit menu or return home.

Default Display Screens: Cycle through using Left/Right on the joystick from the home screen.

Screen 1: Large numerical readout of primary sensor.
Screen 2: Multi-sensor dashboard with bargraphs.
Screen 3: Historical trend graph (last 24 hours).
Screen 4: Alarm status and system diagnostics.

Web Interface: Access via http://[unit-ip-address]. Provides full configuration, real-time data, historical logs, and firmware update capabilities.

Maintenance & Troubleshooting

Symptom	Possible Cause	Corrective Action
No display, no power LED	No input power	Check circuit breaker, PoE switch, or 24VDC supply. Verify voltage at terminal block.
Display is dim or unreadable	Brightness setting / Ambient light sensor	Adjust brightness in Menu > Display. Check if ambient light sensor is obstructed.
Sensor reading is incorrect	Wrong scaling / Wiring fault	Re-check sensor configuration scaling. Measure actual signal at input terminal with a multimeter.
Network connection lost	IP conflict / Cable fault	Ping the unit's IP. Check Ethernet cable and switch port. Verify network settings.
Alarm relay not activating	Alarm limit not exceeded / Relay configuration	Verify sensor value is outside alarm limits. Check relay output configuration (NO/NC).
Condensation inside display	Seal failure / Rapid temperature change	Power down unit immediately. Inspect and replace cable gland and door gaskets. Allow unit to acclimate before sealing.

Preventive Maintenance: Bi-annually, inspect all seals, clean the display surface with a soft, damp cloth, and verify sensor calibration.
