sets the seconds to 30 (and the sub-seconds counter to 0). The hour is disregarded by

the controller check.

Example

If the synch code is sent at (HRS:MINS:SECS) XX:08:30 and Real time clock is

between XX:08:01 and XX:08:59, it will be re-synchronised to XX:08:30.

...where ‘XX’ is any hour.

(N.B. As the real time clock is unlikely to be a whole hour in error, the hour is

ignored.)

If the real-time clock error is greater than + 29 seconds, the synchronisation code is

ignored and synchronisation confirm (‘CC1’) is not returned.

9.3.4 Reply Bits

See Figure 21.14.

9.3.4(a) Stage Confirm (G1,G2 etc.)

A single ‘G’ bit is returned when the specified stage is active, i.e. all fixed phases

within the stage are at green (see section 2.3).

If required, the controller can be programmed so that more than one stage returns the

same ‘G’ bit whenever the different stages are active. In this case the ‘G’ bit will not

stay active during any interstages between two stages with the same ‘G’ bit unless the

controller is specifically programmed to do so. (See section 9.3.3).

Two ‘G’ bits returned simultaneously, normally ‘G1/G2’, may be programmed to

indicate any of the following conditions:

(i) Manual mode selected and operative.

(ii) Manual mode selected.

(iii) No lamp power.

(iv) Detector Fault Monitor timed out.

(v) NORMAL mode select button not selected, i.e. MANUAL, FIXED

TIME or V/A.

(vi) An entry in the controller fault log.
