9.12 MODE PRIORITY

The mode priority facility allows for the mode with the highest priority for which

operating conditions are active (e.g. force bits from the UTC computer or a hurry call

demand) to be the current mode. When the operating conditions become inactive, then

the next highest priority mode with operating conditions active will become the current

mode. It need not necessarily be the next one in line. If at any time operating

conditions for a higher priority mode become active, then that mode will become the

current mode. If more than one set of operating conditions are active then the mode

with the highest priority will become the current mode.

In order to achieve this facility, the mode select buttons on the manual panel are left in

the NORMAL position.

The current mode may be read via the handset using the MOD command.

If VEHICLE ACTUATED mode is in the priority list then this must be put as the

lowest priority. If VA mode is not required then FIXED TIME mode must be the

lowest priority.

For priority purposes, SELECTED MANUAL CONTROL and SELECTED FIXED

TIME, CLF OR VA are considered as modes. The operating conditions for these

modes are the relevant mode select buttons being selected, i.e. MANUAL, FIXED

TIME, CLF or VA.

Fixed time, CLF or VA selected via the manual panel are considered as different

modes to ‘normal’ VA, CLF or Fixed time modes. This allows VA or Fixed time to be

configured as the lowest mode, i.e. the one in which the controller will operate if no

higher priority modes are requested. Whilst SELECTED VA or FIXED TIME mode

can be configured higher up the mode priority table, so that if necessary, the controller

can be forced to operate in VA or Fixed time, even if there are requests for modes of

higher priority than the basic VA or Fixed time.

e.g.

Priority Mode(s)

1 Selected VA, CLF or fixed time*

2 Hurry

3Priority

4UTC

5CLF

6VA

(* This will allow controller to be forced to operate in the Selected mode even if any of

modes 2-4 are requested to be active).

To select Fixed Time, CLF or VA, the appropriate mode select button on the manual

panel must be selected.
