1.4520.668 – MIC5 E2 Tr2 index to early / faulty
Yellow alarm. Initiated by MIC5.
Cause
Corrective action
Index mark of pulse sensor 2
(B75) detected too early or faulty.
u
Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
1.4520.669 – MIC5 E2 Tr2 index to late / missing
Yellow alarm. Initiated by MIC5.
Cause
Corrective action
Index mark of pulse sensor 2
(B75) detected too late or
missing.
u
Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
1.4520.670 – MIC5 E2 Tr3 synchronisation fault
Yellow alarm. Initiated by MIC5.
Cause
Corrective action
Unable to synchronize with signal
from pulse sensor 3 (B13.2).
u
Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
1.4520.671 – MIC5 E2 Tr3 operational error
Red alarm. Initiated by MIC5.
Cause
Corrective action
Pulse sensor 3 (B13.2) has
tripped an operational error.
1. Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
2. Restart ignition control unit.
1.4520.672 – MIC5 E2 Tr3 no signal detected
Yellow alarm. Initiated by MIC5.
Cause
Corrective action
No signal from pulse sensor 3
(B13.2).
u
Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
1.4520.673 – MIC5 E2 Tr3 polarity detection fail
Yellow alarm. Initiated by MIC5.
Cause
Corrective action
Unable to detect polarity of pulse
sensor 3 (B13.2).
u
Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
1.4520.674 – MIC5 E2 Tr3 wrong polarity
Yellow alarm. Initiated by MIC5.
Cause
Corrective action
Pulse sensor 3 (B13.2) has wrong
polarity.
u
Check sensor, sensor gap, cabling, data record settings and timing
wheel. Replace sensor as necessary. (→ Page 202) (→ Page 201)
