Connection to Digital Clock#

Caution

It is important to configure DIP switch position to DCF.

Connect the DCF receiver (AD 650) to the clock terminal board placed on the anchoring plate (LINE IN terminal) using an unshielded two-wire cable with double insulation (a 10 m cable is included in the delivery). The maximum length of the cable depends on its cross-section (at least 0.25 mm²) and can be up to 200 m. We recommend using shielded cable only in critical conditions.

The functionality of the receiver is independent of the connection polarity. Cut the cable to the required length.

With good reception, the LED on the receiver flashes once per second with a skip of 1 pulse at the 59^th second.

Note

In case of issues with receiving the DCF signal when using the AD 650 / DCF 4500 receiver, it is necessary to ground (connect to PE) one of the signals/inputs (LINES+ or LINES-).

For the ECO-DC clock, it is always necessary to ground one (connect to PE) of the signals/inputs (LINES+ or LINES-).
