Unpack and verify contents. Ensure the installation environment is clean, dry, and within specified temperature limits.
WARNING! Disconnect power before making any electrical connections. Ensure wiring complies with local electrical codes. The device contains electrostatic-sensitive components; handle with appropriate precautions.
Apply power. The device performs a self-test (all display segments illuminate briefly).
CAUTION! Incorrect parameter settings may lead to improper system operation. Verify settings before placing into service.
Front Panel: 4-digit LCD display, 4 tactile buttons (MENU, UP, DOWN, ENTER), LED status indicator.
Display Symbols: 'A' (Analog output active), 'R1'/'R2' (Relay energized), 'Err' (Fault).
Menu Structure: Access by pressing MENU. Navigate with UP/DOWN, enter submenus with ENTER.
- PArA: Select measured parameter and unit.
- oUt1: Configure 4-20mA output scaling.
- rEL1, rEL2: Set relay trigger points and hysteresis.
- CoMM: Set Modbus address (1-247) and baud rate.
- diAG: View min/max values, reset to defaults.
Default Settings: Parameter: Pressure (PrES), Unit: bar, Address: 1, Baud: 9600.
To PLC/SCADA via Analog: Connect the 4-20mA output to the analog input module of your controller.
To PLC/SCADA via Digital: Connect relay contacts to digital inputs for alarm/control functions.
To Network via Modbus RTU: Connect RS-485 terminals to a Modbus master (PLC, PC with adapter). Ensure unique addresses and proper termination (120 Ω resistor at bus ends).
Tip: For long cable runs (>1000m), use repeaters and verify signal integrity.
All settings are made via the front keypad. The device stores configuration in non-volatile memory.
WARNING! Unauthorized calibration may void warranty and affect measurement accuracy. Record original settings before making changes.
Normal Measurement Mode: Displays current measured value. The bargraph provides a visual trend. Relay and analog outputs are active according to configuration.
Peak Hold Mode: Can be enabled in the menu. The display shows the maximum value recorded since the last reset.
Valley Hold Mode: Can be enabled in the menu. The display shows the minimum value recorded since the last reset.
Display Off Mode: The backlight can be set to turn off after a period of inactivity to save power.
Routine Maintenance: Periodically inspect the device for physical damage, clean the display with a soft, dry cloth, and check terminal tightness (power off).
Recommended Calibration Interval: 12 months, or as required by your quality system.
Calibration Procedure:
1. Connect the device to a stable power supply and a precision reference standard.
2. Access the CAL menu (password 1234).
3. Apply a zero-point reference (e.g., atmospheric pressure for gauge pressure). Select "CAL0" and confirm.
4. Apply a span-point reference (e.g., 10.00 bar). Select "CAL1" and confirm.
5. Exit the menu. The device is now calibrated.
CAUTION! Perform calibration in a controlled environment. Use only appropriate, calibrated reference equipment. Incorrect calibration can lead to significant measurement errors.
EMC Directive 2014/30/EU: Complies with emission and immunity standards for industrial environments.
Low Voltage Directive 2014/35/EU: Complies with safety requirements.
RoHS Directive 2011/65/EU: Complies with restrictions on hazardous substances.
FCC Part 15: Class A digital device. This equipment may cause radio interference in residential areas; the user may be required to take corrective measures.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Display is blank | No power, incorrect voltage | Check power connections and voltage (24V DC ±10%). Ensure polarity is correct. |
| Display shows "Err1" | Sensor input open circuit or short circuit | Check sensor wiring and connections. Verify sensor is functional. |
| Display shows "Err2" | Internal memory error | Cycle power. If persistent, perform a factory reset (see below). Contact support if error remains. |
| Analog output incorrect | Wrong scaling, load impedance too high | Check output configuration (oUt1 menu). Ensure load ≤ 500 Ω. |
| Relay does not switch | Setpoint misconfigured, faulty load | Verify relay settings (rEL1/rEL2). Check the connected load does not exceed relay ratings (5A). |
| No Modbus communication | Wrong address, baud rate, wiring fault | Verify device address and baud rate in CoMM menu. Check RS-485 wiring (A, B, GND) and termination. |
| Unstable reading | Electrical noise, process instability | Ensure sensor cable is shielded and away from power lines. Check for air bubbles or pulsations in fluid systems. |
Factory Reset: With power off, press and hold UP and DOWN buttons. Apply power while holding buttons for 5 seconds. Release. All settings will revert to defaults (Address=1, Parameter=Pressure).
Service: Do not attempt to repair the device yourself. For service, contact Sygonix support at +49 (0)XXX XXXX XXX or [email protected]. Provide the model number (3344071) and serial number.
