โ ๏ธ Safety Note: Keep the power supply disconnected during installation. Follow the wiring diagram closely. Respect specified voltage/current limits for each terminal.
NPN models (WN): Control signal between S and A2.
PNP models (WP): Control signal between S and A1.
Terminal S is used in functions E, F, G, I, J (and can be left open for A, B, C, D, H if not required).
๐ ๏ธ Parameter Setting Guide
- Enter Configuration Mode: Press and hold the button until the LED starts flashing. You are now in the parameter menu.
- Select Function (AโJ): The first setting is the function code. Use the button to cycle through A, B, C, ... J, then confirm by pressing and holding until the LED pattern changes.
- Set Time Range(s): Depending on the function, set coarse time range and fine time for T1 (and T2 if applicable). When the green LED lights, add 5% to the scale value for precise timing.
- Confirm and Store: After all parameters are adjusted, press and hold the button until the LED stops flashing. The settings are stored.
- Power Cycle to Activate: Turn the supply off and on again. The relay will now operate with the new function and timing values.

โ Frequently Asked Questions
๐น How do I select a function (e.g., Function E โ Off-Delay)?
Enter configuration mode by long-pressing the button until the LED flashes. The first parameter is the function code. Cycle through letters AโJ using short presses, then long-press to confirm. The next parameters will be the time ranges for that specific function.
๐น Do I need to wire the S terminal for all functions?
No. Functions A, B, C, D, and H operate autonomously from the supply voltage (S can be left open). Functions E, F, G, I, and J require the S control signal to initiate timing or toggling. Always check the function diagram for your chosen mode.
๐น Can I use this relay on both AC and DC?
Yes. The FCT18-M accepts 12โ240V AC or DC on terminals A1โA2, making it universal for worldwide control panels.
๐น What is the accuracy of the timing?
The digital setting provides 0% setting deviation (no potentiometer drift) and 0.2% repeat accuracy, ensuring extremely precise timing cycles every time.
๐น What is the mechanical life of the output contacts?
The relay has an outstanding mechanical life of 1ร10โท operations. Electrical life is 1ร10โต operations at rated 16A/250V AC load.
๐น Can I change the function without losing my time settings?
When you enter configuration mode and select a new function, the default time range for that function is loaded. We recommend noting down your preferred values before changing, as previous settings for the prior function will be overwritten.
