For an FYA channel pair the fault configuration parameters are applied to the
Primary
channel with three inputs, Ra-Ya-fYa. The fault configuration parameters programmed for
the
S
parse
channel of the FYA pair with only one input, Ga, only affects the sparse
channel and not the Primary channel, and should be used only when the RY INPUT Enable
option is Enabled for that channel.
2.16.2.1 CONFLICT
The CMUip-2212 will verify that no conflicting channels to the solid Yellow arrow channel
(clearance) are active as determined by the Program Card compatibility programming of
the solid Yellow arrow channel of the pair except during the following sequences:
2.16.2.1.1 PROTECTED YELLOW CHANGE INTERVAL CONFLICT
During the Yellow change interval of the Protected Turn channel (Green arrow), the CMUip-
2212 will verify that no conflicting channels to the solid Yellow arrow channel (clearance)
are active as determined by the Permissive compatibility programming of the Protected
Turn channel (Green arrow) of the pair.
2.16.2.1.2 PERMISSIVE YELLOW CHANGE INTERVAL CONFLICT
During the Yellow change interval of the Permissive Turn channel (flashing Yellow arrow),
the CMUip-2212 will verify that no conflicting channels to the solid Yellow arrow channel
(clearance) are active as determined by the Permissive compatibility programming of the
Permissive Turn channel (flashing Yellow arrow).
2.16.2.2 RED FAIL
A Red Fail fault will occur if the solid Red Arrow AND solid Yellow Arrow AND flashing
Yellow Arrow AND solid Green Arrow all remain inactive for the Red Fail fault response
time. The fault status will be displayed for both channels of the FYA channel pair.
If the Red Fail function is enabled and the RY Input option is Enabled for the sparse
channel (Ga), then a Red Fail fault will occur if the Red AND Yellow AND Green all remain
inactive on the sparse channel for the Red Fail fault response time. The fault status will be
displayed for the sparse channel of the FYA pair.
2.16.2.3 DUAL INDICATION
A Dual Indication fault will occur if any two or more of the solid Red Arrow, solid Yellow
Arrow, flashing Yellow Arrow, or solid Green Arrow signal combinations are active
