MMU-16LE SmartMonitor
Operations Manual
Eberle Design Inc. Page 21
If a channel pair is enabled for FYAc operation, the MMU-16LE SmartMonitor
®
will monitor
the FYA logical channel pair for the following fault conditions:
a. Conflict
i. Channel conflicts are detected based on the Permissive programming
jumpers on the Program Card for each channel. This operation remains
unchanged from normal Nema operation.
b. Red Fail
i. 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 icon (

) will be
displayed for both channels of the pair. The Red and Yellow inputs for
channels 9, 10, 11, 12 do not affect the Red Fail condition for the FYAc
channels 1, 3, 5, 7.
c. Dual Indication
i. 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 simultaneously for the Dual Indication
fault response time. The fault icon (

) will be displayed for the FYAc
channel 1, 3, 5, 7. The fault icon (

) will also be displayed for the solid
Green Arrow channel (9, 10, 11, 12) IF the solid Green Arrow was
active.
ii. If the RG, RY, or GY Dual Indication function is enabled for the solid
Green Arrow channels (9, 10, 11, 12) then a Dual Indication fault will
occur if any two or more of the Red, Yellow, or solid Green Arrow inputs
(9, 10, 11, 12) are active simultaneously for the Dual Indication fault
response time.
d. Clearance
i. A Clearance fault will be detected if the FYAc channel pair sequences
from the solid Green Arrow (9, 10, 11, 12) to the solid Red Arrow (1, 3,
5, 7) without a minimum clearance time on the solid Yellow Arrow (1, 3,
5, 7). The fault icon (

) will be displayed for the FYAc channel (1, 3, 5,
7).
ii. A Clearance fault will be detected if the FYAc channel sequences from
the flashing Yellow Arrow (1, 3, 5, 7) to the solid Red Arrow (1, 3, 5, 7)
without a minimum clearance time on the solid Yellow Arrow (1, 3, 5, 7).
The fault icon (

) will be displayed for the FYAc channel (1, 3, 5, 7).
iii. A Clearance fault will be detected if the Green Arrow (9, 10, 11, 12)
channel sequences from the solid Green Arrow (9, 10, 11, 12) to the
Red (9, 10, 11, 12) without a minimum clearance time on the Yellow (9,
10, 11, 12). The fault icon (

) will be displayed for the solid Green
Arrow channel (9, 10, 11, 12).
