General description
The Master Clock Programmer is a combination of yearly programmer with 8 outputs for control and regulation
of various energy consumers such as electrical striking plates, buzzers for pause signalling etc,
and a quartz Master Clock with two outputs for operating Slave Clocks.
In case of power failure the built in Real Time Clock keeps the internal time updated. (the outputs are set to
position OFF). Connected Slave Clocks are automatically corrected by rapid impulsing when power returns and
the outputs resume their positions
(ON/OFF) which were previously programmed (with a 10 second switching delay between the different outputs.
Entered data’s are stored for at least 100 years.
The Master Clock Programmer have pre-programmed fixed public holidays and summer/winter time
correction (daylight saving). The clock offers full flexibility with regard to programming working days between
holidays, public holidays to weekdays, holiday periods etc.
A total of 800 control functions can be programmed over 8 outputs. Repeating daily functions on a certain
output only requires 1 control function. Further relay outputs (up to 64) possible by adding one or more
Expansion Units, which are connected to the minute impulse line and to current connection voltage.
