⚠️ Replacement Selection Guide (Original discontinued)

1. UC6000-FP-E7-R2-P5: Same FP housing, output changed to NPN, same range and dimensions
2. New IO-Link version: UB6000-F42 series (vivienda cuadrada, Enlace IO, 6 rango m, successor for old FP series)
3. Cylindrical alternative: UC6000-30GM-E6R2-V15 (M30 cylindrical, 6 rango m, 2 PNP outputs, RS232, conector M12)

📌 Troubleshooting (Common issues for this model)

1. Red LED flashing: Weak echo / heavy ambient noise. Check transducer surface for condensation, polvo, strong airflow; increase response time.
2. Fluctuating distance reading: Multiple sensors operating in the same area → enable sync line; or adjust mounting angle to avoid multiple reflections.
3. RS232 communication failure: Confirm serial parameters 9600,N,8,1. Note the sensor uses non-standard RS232 voltage levels, requires dedicated adapter, cannot connect directly to PC serial port.
4. Switch outputs not activating: Verify NO/NC configuration, correct wiring for PNP load, ensure load current ≤200 mA.

ULTRA3000 Configuration Procedure (For UC6000-FP-E6-R2-P5)

Important prerequisite: ULTRA3000 is dedicated Pepperl+Fuchs software for legacy ultrasonic sensors. Only compatible with Windows XP / Win7 (32/64poco). Direct execution on Win10/11 is unstable; Win7 virtual machine recommended.

Fixed serial parameters: 9600 baudios, norte,8,1 (sin paridad, 8 bits de datos, 1 bit de parada). The sensor uses non-standard RS232 levels. Do NOT connect directly with ordinary USB-to-RS232 adapters. Pepperl+Fuchs dedicated R2 level converter cable is required.

1. Hardware Wiring Preparation (FP housing P5 terminal box version)
2. Power the sensor with DC15~30V, power on and confirm green power LED is steady ON.
3. Open sensor terminal box, route RS232 signals of R2: TXD, RXD, Tierra

Sensor TXD → Adapter RXD

Sensor RXD → Adapter TXD

Common GND connection is mandatory; communication failure is highly likely without common ground

3. Connect dedicated RS232 adapter to PC serial / USB-to-serial port (P+F R2 level conversion is mandatory; generic RS232 modules cannot communicate)
4. For multi-sensor synchronization: parallel sync wires. Sync line can be left disconnected during commissioning.
5. DIP switch setting: Enable R2 serial port, set corresponding DIP to OFF to activate RS232 communication (DIP on PCB inside FP housing).

90% of communication failures are caused by: missing P+F dedicated level adapter, crossed TX/RX reversed, no common ground, R2 serial port disabled via DIP.

2. Software Installation & Serial Port Identification
3. Install ULTRA3000 following setup wizard; English UI only (no Simplified Chinese).
4. Open Device Manager and check COM port number (USB-to-serial creates virtual COM).
5. Launch ULTRA3000, enter main window, open menu【Serial Port】.
6. Select corresponding COM port, fixed parameters: 9600 / Ninguno / 8 /1.
7. Click Connect to establish connection. If successful, software reads sensor model, firmware version and factory parameters. If failed, check hardware above.

Four core panels in main interface:

Graph: Real-time distance curve, echo waveform, switch point markers

Parámetro: All adjustable parameters

Mostrar: Live measured distance, output status, LED simulation

Command: Low-level serial command debugging

3. Read Original Sensor Parameters (Recommended first step)
4. After successful communication, click【Read from sensor】to upload current sensor parameters to software.
5. Use【Save to file】to save parameter file (.par) for backup for future recovery.
6. Core Parameter Configuration (UC6000-FP-E6-R2-P5, dual PNP outputs)

Go to Parameter panel and adjust key settings:

4.1 Rango de medición & Blind Zone

Min distance: fijo en 800 mm (blind zone, cannot be lower)

Max distance: 6000 mm

You may reduce maximum range for your application to improve response speed and noise immunity.

4.2 Switch Output Q1, Q2 (2 PNP channels)

Each channel can be configured independently:

Switch point 1 (near point)

Switch point 2 (far point)

Modo de operación:

Modo ventana: Output active between two thresholds (widely used for level measurement)

Single point mode: Trigger when distance above / below threshold

Lógica de salida: NO normalmente abierto / NC normalmente cerrado (for PNP outputs)

Histéresis: Recomendado 1% of set distance to suppress jitter

Ejemplo (alto + low bin level dual alarm)

Q1: Window mode for low level; Q2: Single point mode for high level.

4.3 Tiempo de respuesta & Filtración (Anti-jitter, airflow interference)

Tiempo de respuesta: Min.180 ms, por defecto 360 EM; extend to 540 ms for dusty / high airflow environments

Filter: Moving average filter. Higher filter count = more stable reading, respuesta más lenta

Sound velocity: Built-in temperature compensation, normally no manual adjustment needed; manual calibration available for high-precision applications.

4.4 Sincronización (Multi-transducer anti-crosstalk for overlapping detection zones)

Sync mode: Soltero (single sensor) / Master / Slave

Multi-sensor setup: 1 Master, others Slave. Max sync frequency ≤7Hz divided by sensor count; arriba a 5 transducers.

4.5 Diagnóstico & Alarma

Echo loss: Echo loss threshold

Fault behaviour: Hold / drop outputs when echo is lost.

5. Download Parameters to Sensor
6. After finishing parameter setup, click【Write to sensor】to write settings into sensor.
7. After writing, software automatically reads back parameters, verify written values match configured values (critical check).
8. Execute【Store User Configuration】SUC to permanently save parameters into sensor Flash memory.

⚠️ Without SUC save, parameters revert to factory defaults after power cycle! This is the most common mistake.

6. Online Debugging & Calibración (Graph panel)
7. Open Graph real-time plot, observe echo waveform and identify spurious echoes (sidewall reflection, multi-reflection caused by dust).
8. Move reflector target to near and far setpoints to verify Q1/Q2 output status; simulated LEDs in software change synchronously.
9. If distance reading jumps:

Increase filtering and extend response time

Check mounting angle to avoid sidewall reflections

Enable synchronization for multiple sensors

4. Logging:【Record measurement】, export curve for failure analysis.
5. Disconnect & Field Commissioning
6. Close serial connection in ULTRA3000.
7. Disconnect RS232 debug cable; keep sensor powered with normal wiring for operation.
8. Field test: block / remove reflector target to verify switching action of 2 PNP outputs.

Common Communication Troubleshooting for ULTRA3000

1. Connect failed, cannot read sensor

Check DIP switch, confirm R2 serial port enabled

TX/RX crossed, common ground connected; P+F R2 level adapter is mandatory for communication

COM port occupied by other software, close serial assistant tools

2. Parameters written successfully, but reset to factory after power cycle

→ SUC save (Store User Configuration) was skipped

3. Unstable distance reading, messy echo waveform

→ Airflow, polvo, sidewall reflections; increase filtering, enable synchronization, adjust mounting angle

4. Software reads distance correctly, but Q1/Q2 outputs do not trigger

→ Check NO/NC logic, PNP load wiring, hysteresis and window mode settings

Suplemento: Low-level Command Mode (Command panel for advanced debugging)

Raw P+F serial commands can be sent directly to read/write parameters, suitable for automated script debugging e.g. distance reading and switch point modification.

UC6000-FP-E6-R2-P5 Terminal Box RS232 Pin Definition

Modelo aplicable: UC6000-FP-E6-R2-P5 (P5 = built-in terminal box, non-M12 version)

Important reminder: The sensor R2 interface uses Pepperl+Fuchs proprietary non-standard RS232 voltage levels, not standard PC RS232. Pepperl+Fuchs R2 level converter is required; generic USB-to-RS232 cannot communicate.

1. Terminal Numbering & Signal Definition inside Terminal Compartment

Open sensor housing terminal chamber, terminal block signals:

✅ Communication Wiring Rule (Crítico)

Sensor TXD(7) ↔ Adapter RXD

Sensor RXD(6) ↔ Adapter TXD

Sensor RS232 GND(8) ↔ Adapter GND, and short to power 0V (Terminal 2).

Communication will almost certainly fail if only TX/RX are wired without GND.

✅ Commissioning state: DIP1=OFF, all others OFF.

DIP1 can be switched ON to close serial port and reduce interference during normal operation without debugging.

3. Pepperl+Fuchs R2 Level Converter (Matching Hardware)

Modelo: K-ADP-R2 (P+F dedicated R2 level converter)

One side: connect sensor terminals 6,7,8 (TX/RX/GND)

Other side: standard RS232 level, connect to PC serial / USB-to-RS232

Without K-ADP-R2, generic USB-to-RS232 cannot detect sensor serial signal.

4. Pre-power Wiring Checklist
5. Fuerza: Terminales 1 & 2, DC15~30V. Observar la polaridad.. Reverse polarity protection exists but inspection is still required.
6. Comunicación: Terminales 6 &7 cross-connected; terminal8 shorted to power 0V for common ground.
7. Sincronización: Leave terminal5 floating for single sensor; parallel all SYNC terminals for multi-sensor network.
8. interruptor DIP: DIP1 set OFF to enable R2 serial port.
9. Cableado de salida: Q1/Q2 are PNP type. Connect one end of load to Q1/Q2, the other end to 0V.
10. LED Indicator Description (LEDs outside terminal box)

LED verde: Steady ON = Power OK; OFF = No power / power fault

LED amarillo: Output status, lights up when Q1/Q2 is activated

LED rojo: alarma de fallo; flashing = weak echo / abnormal signal; steady ON = hardware fault
