General
The Westerstrand master clock TIME CONTROL I combines a control unit for secondary clocks, an NTP time server and a year programmer with two outputs for controlling various energy consumers such as electric strike plates, break signals, etc.
The network connection can be used for time distribution, remote control, alarm management and monitoring.
For time distribution, standardized NTP (Network Time Protocol) is used and for alarms and monitoring, SNMP is used. It can act as a primary NTP server or as an NTP client. Devices connected to the network with support for NTP can receive the correct time from the Westerstrand TIME CONTROL I.
All parameters such as the type of time system, pulse type and length, network parameters, etc. can be configured by the user. It is also equipped with an automatic measurement function that measures the impulse voltage and current.
The programmer has fixed holidays and summer/winter time pre-programmed. The device offers full flexibility in terms of programming working days between holidays, holidays to weekdays, vacation periods, etc.
Configuration of network settings, light intensity and other parameters is done in a web browser.
Power failure
In the event of a power failure, the time continues to run internally in the master clock. Connected secondary clocks are corrected after a power failure by rapid impulses.
Synchronization
The clock is preset for time synchronization via internal time. External synchronization available as option.
