19.3 L.M.U. PARALLEL STAGE STREAMING FACILITIES

19.3.1 LMU Supplementary Intergreen Extensions

There is an LMU supplementary intergreen extension facility available for each stream.

If an LMU indicates one red lamp fail (see Section 19.2) then the all red period of the

intergreens on the configured stage to stage movements will be held until the

supplementary extension timer expires. The extension period is measured from the

stage change point. Each stream’s extension can be accessed by using the handset

command:

SIE followed by the stream number (e.g. SIE 2). Data is in the range 0 to 31.8 seconds

in 0.2 second steps.

19.3.2 LMU Maximum All Red

There is an LMU maximum all red facility available for each stream. If an LMU

indicates a second red lamp failure pending (see section 19.2) then the all red period of

the intergreens on the configured stage to stage movements will be held until the LMU

maximum all red timer expires. The maximum period is measured from the stage

change point. Each stream’s maximum can be accessed by using the handset command:

LMX followed by the stream number (e.g. LMX 0). Data is in the range 0 to 255

seconds in 1 second steps.
