Master Clock Q

- A unit that controls all clocks connected in a timing system.
- Summer/winter time adjustment.
- Automatically resets correct time after e.g. a power outage.
- Pulse output for controlling various types of clocks.
 
General
The master clock is the brains in a timing system. All of the smart functions such as summer/winter time adjustment and time reset after power outages etc. reside here.
It has a preprogrammed annual calendar/almanac with the year’s public holidays already entered.
The type of communication that controls the slave clock is chosen in the master clock, e.g. 24 VDC pole-switching minute pulses, Time code or NTP if the Ethernet card option is built into the master clock.
For extra accuracy, an external signal receiver e.g. GPS can be connected to the master clock.
Power outage
In the event of a power outage, the master clock retains its settings for up to 72 hours. If power is restored within this period, the master clock automatically resets all clocks in the system.
