T400 Controller Facilities Manual

667/EB/20200/000 Page 17-15 Issue 9

17.12.3 Special Detector checking.

This facility is used in VA Mode. When enabled the Controller checks that during the

Vehicle Green period the detector output changes state. If no change in state is

detected then the All Red period is set to 3 Secs.

NOTE The use of these commands is fully explained in the T400 Controller Handset

Command List. (See section on Pelican).

17.13 CLF FACILITIES

The only effect of CLF on a pelican controller is to provide a ped. inhibit signal. There

is a corresponding group influence to cancel this ped inhibit influence i.e. an “Allow

Ped” influence which is used to provide a ped window. This CLF inhibit signal inhibits

the Pedestrian phase for as long as this input is active provided that there is an Allow

Ped influence somewhere in the same group. If there is no Allow Ped influence within

the same group then the CLF input has no effect.

17.14 CROSS INHIBIT LINKING (DUAL PELICAN)

To ensure that both pedestrian phases do not run green simultaneously enter the

required handset command. For simultaneous demands stream 0 is the Master stream

and stream 1 the slave. i.e. if simultaneous pedestrian demands are received the Master

stream will run the Ped. phase but the slave stream will be inhibited until such time that

the Traffic green on Stream 0 is re-established.
