Schneider Electric Digital Time Switch - M Series - CCT15854

The battery backup maintains the internal clock and stored program settings for up to 10 years (52560 hours) even when the main AC power is disconnected. This prevents the need for reprogramming after power interruptions.

No, the CCT15854 model is a single-channel device, meaning it can only control one load or circuit at a time.

Use the 'Mode' and arrow buttons to navigate to the time setting menu on the digital display. Adjust the hour, minute, and day as indicated on the screen.

The time switch allows for a maximum of 56 switching operations (ON/OFF commands) within a 7-day weekly program cycle.

This device is designed for panel building and indoor installation. It should be protected from environmental elements like moisture and extreme temperatures if considering any non-standard application.

It operates on a standard AC supply voltage ranging from 196V to 253V at a frequency of 50Hz or 60Hz.

The time switch is 18mm wide, equivalent to 2 standard 9mm modules, making it space-efficient for DIN rail mounting.

Verify the AC power supply is connected correctly and within the specified voltage range (196-253V). Check fuses or circuit breakers supplying power to the device.

Ensure the current time and day are set correctly. Double-check the programmed ON/OFF times for accuracy and ensure they are not conflicting. Confirm the correct channel is being used.

Check the AC power connection. If the display remains blank after confirming power, the unit may require replacement.

Ensure you are correctly initiating the manual override sequence as per the user manual. Check if the programmed schedule is overriding the manual command due to specific settings.
