General
Quartz master clock WDP-Y mini with impulse output for operation of slave clocks.
The clock has a programmable relay output for control of, for example, illumination or pause signals.
The relay output can be programmed with 40 different ”signal points”.
A built-in temperature compensated quartz crystal oscillator gives high accuracy also when the ambient
temperature is varying. Optional time signal receivers can be connected for extra high accuracy. Minute impulse
synchronisation is also possible.
Changing from winter time to summer time and vice verse is fully automatic and does not need programming.
In case of power failure, an internal memory keeps the correct time for 24 hours.
Note: Activation or deactivation of the relay is not possible during power failure.
The connected slave clocks are corrected after the power failure by means of rapid impulsing.
The impulse output has a short-circuit protection with automatic reset.
In the event of short-circuit, the alarm LED is lit and outgoing impulses are inhibited.
