1. Pengenalan
This manual provides essential information for the safe and correct use of the KEYENCE FS-T2 Simple Fiberoptic Amplifier NPN Cable Type. The FS-T2 is designed as a child unit, requiring connection to a compatible main amplifier (e.g., FS-T1/M1/V1/PS-T1, LV-21A/11A, CZ-V1) for power supply and operation. Please read this manual thoroughly before installation and operation, and keep it for future reference.
2. Maklumat Keselamatan
To ensure safe operation and prevent damage to the product or injury to personnel, observe the following precautions:
- Jangan cuba membuka, membaiki atau mengubah suai unit.

4. Persediaan dan Pemasangan
4.1 Pemasangan
The FS-T2 unit is designed for DIN rail mounting. Ensure the DIN rail is securely attached to a metal plate for optimal performance, especially when multiple units are connected.
4.2 Pendawaian
The FS-T2 is an NPN output type. Connect the unit to a compatible main amplifier and ensure correct polarity. Refer to the wiring diagram for detailed connection instructions.
Figure 4.1: Wiring diagram for the KEYENCE FS-T2, showing the NPN output circuit and connections for 12-24 VDC power and solid-state input.
The output circuit includes reverse connection protection, overcurrent protection, and surge absorption. The NPN open collector output has a maximum current of 100mA (40V or less) with a residual voltage daripada 1V atau kurang.
4.3 Menyambung Berbilang Unit
This unit can be connected with other units of the same model through its connector. Up to 16 units can be connected side-by-side (total 17 units including the main amplifier). When expanding, ensure the units are mounted on a DIN rail (attached to a metal plate) and the output current is kept below 20mA per unit. Note that ambient temperature ratings may change when multiple units are connected:
- For 3-10 connected units: -10 to +50°C
- For 11-16 connected units: -10 to +45°C
5. Arahan Operasi
5.1 One-Touch Calibration
The FS-T2 supports one-touch calibration. Refer to the main amplifier's manual for specific calibration procedures, as the FS-T2 is a child unit.
5.2 Penukaran Mod
The operation mode can be switched between Light ON and Dark ON using the designated switch. The unit also features timer functions including ON-delay 40ms, OFF-delay 40ms, and Timer OFF, selectable via a switch.
5.3 Petunjuk
The unit is equipped with several indicator lights:
- Penunjuk Output: Red LED, illuminates when output is active.
- Stable Operation Indicator: Green LED, indicates stable detection.
- Tuning Indicator: Green LED, assists during sensitivity adjustment.
6. Penyelenggaraan
The KEYENCE FS-T2 is designed for minimal maintenance. Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents. Regularly inspect wiring for any signs of damage or loose connections.
6.1 Unit Removal
To remove the unit from the DIN rail, slide the unit to the right and then lift it off the rail. Ensure power is disconnected before removal.

7. Penyelesaian masalah
If the unit does not operate as expected, consider the following:
- Tiada Kuasa: Verify that the main amplifier is powered on and correctly connected to the FS-T2. Check all wiring connections.
- No Detection/Unstable Detection: Ensure fiber optic cables are clean and properly inserted. Perform one-touch calibration again. Check ambient light conditions; excessive illumination (over 10,000 lux for incandescent, 20,000 lux for sunlight) can affect performance.
- Output Not Switching: Check the operation mode switch (Light ON/Dark ON). Verify the timer function settings.
- Interference with Other Units: Ensure proper spacing or use interference prevention settings if available on the main amplifier. The FS-T2 supports up to 16 interference prevention units.
If issues persist, consult the main amplifier's manual or contact KEYENCE support.
