Self-adjusting clock systems

Features and advantages of Schauer master clocks and central units with self-adjusting slave clocks

Time Code (TC)
Analogue clocks like these are supplied and controlled via the serial time code of a corresponding BMC master clock, which comprises data on year, month, day, hour and minutes. Each clockwork has its own microprocessor in order to receive the time code, to recognise the hand position and finally, to also set the hand at the correct time automatically.

Each time-code clock is connected to a two-wire bus system, which supplies the 24V DC electricity and the serial time code (the advantage of simple cabling). A mixed mode operation with impulse-controlled slave clocks is thus also possible. This means that with an existing clock system not all slave clocks need to be changed straight away.

The TC slave clocks change automatically and rapidly to the 12 o’clock position and stay there until the correct time information is received from the master clock via time code. Should this be the case, the analogue clock automatically and rapidly changes to show the correct time. When the clock is automatically calibrated by the time code, one minute equals one second (e.g. the time change of the clock by one hour takes 60 seconds).

Advantages of 19" clock centrals:

• Central units divide the clock network into clear units and heighten operation reliability
• Extension of other line modules is possible at any time 
• Redundancy between the master clock module and the line module(s), which means when the master clock module malfunctions, the line module continues to function on quartz time. 

Since each manufacturer uses its own data string for time transmission the replacement of an existing master clock is required.
