Connections
-----------

P1 and N are normally connected to the Live and Neutral of the 240VAC power supply but can be connected to an alternative power source.
The D1/D2, S, ECL and ANG terminals are switched to connect to the P1 terminal by relays under control of the microprocessor.
The S2 terminal is switched to connect to the T terminal by a relay under control of the microprocessor.

D1 and D2 are the alternate minute pulses for the slave dial and are active for 6 seconds when energised.  When advancing the slave to correct time (marche/arrêt light blinking), there is a 1 second gap between pulses.

S2 & T are connected to produce hour and half-hour strike pulses.  Each pulse is 0.25 seconds long and the pulses are 2 seconds apart.

S is energised for the duration of hour/half-hour striking, starting coincident with the leading each of the first strike pulse (S2 & T connected) and ending 0.6 seconds after the trailing edge of the final strike pulse.  Each hour strike occurs twice in the French style: on the hour and at 2m30s after the hour.  A single strike pulse is generated at each
half-hour.

ANG is energised for 30 seconds three times a day to activate an Angelus (3 strikes, pause, 3 strikes, pause, 3 strikes, pause, 9 strikes) ringer.

ECL (Eclairage Cadran) is energised twice a day (early morning and evening) to drive slave dial back illumination.

Front Panel Controls

The 3 slider switches enable or programme the Angelus ringer, strike/silent feature and back-lighting.  When set to programming mode, each data entry is activated by pressing the 'validation' button.
