associates channel 1 with 13 [9], channel 3 with 14 [10],
channel 5 with 15 [11], and channel 7 with 16 [12] when PPLT5 Arrow Suppression
monitoring is enabled for that respective approach.
If a channel pair is enabled for PPLT5 Arrow Suppression operation, the MMU-16LE
SmartMonitor
®
will monitor the PPLT5 Arrow Suppression 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 Red Arrow AND Yellow Arrow AND Green
Arrow AND Yellow Ball AND Green Ball all remain inactive for the Red
Fail fault response time. The fault icon (
) will be displayed for both
channels of the pair. The unused Red Ball input for channels 13, 14,
15, 16 [9, 10, 11, 12] does not affect the Red Fail condition.
c.
Dual Indication
i. A Dual Indication fault will occur if any two or more of the Red Arrow,
Yellow Arrow, or Green Arrow (1, 3, 5, 7) signal combinations are active
simultaneously for the Dual Indication fault response time. The fault
icon (
) will be displayed for the channel 1, 3, 5, 7.
ii. If the RG or RY Dual Indication function is enabled for the Yellow and
Green Ball channels 13, 14, 15, 16 [9, 10, 11, 12] then a Dual Indication
fault will occur if any two or more of the Red Arrow (1, 3, 5, 7), and
Yellow Ball or Green Ball inputs (13, 14, 15, 16 [9, 10, 11, 12]) are
active simultaneously for the Dual Indication fault response time. The
fault icon (
) will be displayed for both channels of the pair.
iii. If the GY Dual Indication function is enabled for the Yellow and Green
Ball channels 13, 14, 15, 16 [9, 10, 11, 12] then a Dual Indication fault
will occur if the Yellow Ball and Green Ball inputs (13, 14, 15, 16 [9, 10,
11, 12]) are active simultaneously for the Dual Indication fault response
time. The fault icon (
) will be displayed for the channel 13, 14, 15, 16
[9, 10, 11, 12].
d.
Clearance
i. A Clearance fault will be detected if the channel 1, 3, 5, 7 sequences
from the Green Arrow (1, 3, 5, 7) to the Red Arrow (1, 3, 5, 7) without a
minimum clearance time on the Yellow Arrow (1, 3, 5, 7). The fault icon
(
) will be displayed for the channel (1, 3, 5, 7).
ii. A Clearance fault will be detected if the channel 13, 14, 15, 16 [9, 10, 11,
12] sequences from the Green Ball (13, 14, 15, 16 [9, 10, 11, 12]) to the
Red Arrow (1, 3, 5, 7) without a minimum clearance time on the Yellow
Ball (13, 14, 15, 16 [9, 10, 11, 12]). The fault icon (
) will be displayed
for the channel (13, 14, 15, 16 [9, 10, 11, 12]).
