T400 Controller Facilities Manual

667/EB/20200/000 Page 17-14 Issue 9

17.11 TIMESWITCH FACILITIES

17.11.1 Switch Audio off

This facility allows the pelican ped. audio signal to be turned off on a time of day basis.

The Audio will only switch on/off during the vehicle green period.

17.11.2 Alternative Max. sets

This facility allows the four time sets that are available for each of the modes i.e.

Pelican VA and FVP to be selectable on a time of day basis. To allow the UTC

“Switch to Alternative times” signal (described in 17.10.1) some priority over the

Timeset selection, the Timeswitch selection will only take effect when the UTC signal

is not active.

17.11.3 Switch to FVP mode

This facility disables Pelican VA mode and thus introduces FVP mode on the

pelican/pedestrian controller on a time of day basis.

17.11.4 Enhanced DFM

The later pelican configurations include the enhanced DFM facility, see section

15.9.1(15.9.1(b)).

17.12 CONDITIONING FACILITIES

17.12.1 Dual Level and Audible On/Off control.

Dual level audible operation is enabled via the handset. The changeover relay required

for the switching is located on the first I/O expansion board. Switching between the

two levels is achieved using the event timetable. Note that when using just the Loud

audible indication this I/O line can be used to switch the audible output On/Off. See

Figure 18.2.

When this facility is used no other signals can be allocated to Port 4.

On/Off control is effected as above or via the CPU output lines. The CPU line method

must be used if no expansion board is fitted.

For a Pelican Controller the supply for the Audibles will come from the 2-Phase driver

board.

17.12.2 Real Time Clock Synchronisation.

When enabled by the handset, two lines are dedicated - one to the Sync. input line and

the other to a confirm line. See also UTC facilities information (Section 17.10.1).
