TX500 series technical manual
The preset value is selected using the first shaft encoder to set the MMM value. The second
shaft encoder is used to set the SS value. At the start of each transition the timer counts
down from the preset value or zero if none has been specified.
The timer is locked to the station TC input. Due to this feature a count started by a transition
half way through a second will count that half second as a second to keep in step with the
station TC.
The
<ENTER>
button only appears if the remaining count has been stopped and a positive
remaining time is visible on the display. Selecting this button calculates the duration of the
programme remaining from the last transition by performing the calculation shown. The
button is then removed from the display and the duration is displayed as the remaining
count, which is automatically started (the
<START/STOP>
button automatically toggles from
stop to start).
Duration = currently remaining count - (time of day - time of transition).
