_1172Operation
A speed sensor channel
does not pulse
Incrementer damaged
The AC-3 Power Control (U8) has identified the sensor
bearing as being damaged. The AC-3 Power Control
(U8) monitors sensor to ensure the impulse wires are
single-channel, and to check for sudden changes in the
pulse rate and for constant power supply.
Sensor is damaged (broken wire, short circuit, incorrect
pulses);
Operating system wrongly flags a fault;
AC-3 Power Control component (sensor bearing control)
is faulty
Both sensor tracks are counted. When the first deviation
limit is reached the system waits for a feasible signal
from the suspected broken track. When the second limit
is reached the event is generated.
-Check incrementer signals with multimeter;
-Check speed sensor power supply;
-Check wire connection;
-Replace speed sensor;
-Replace signal-evaluating controller;
_1173Operation
No speed signal from the
travel impulse sensor
although travel sensor
indicates greater than
0.5km/h.
The counts for both incrementers are compared.
Ifthetravel incrementer supplies a speed signal of
>0.05km/h and the travel pulse contact controller
incrementer a speed signal of 0 km/h, the event is
triggered. The activation limit is 100msec.
-Check incrementer signals with multimeter;
-Check wiring with multimeter;
-Replace speed sensor;
_1174Operation
No speed signal from travel
sensor although travel
impulse sensor indicates
greater than 0.5 km/h.
The counts for both incrementers are compared. If the
travel incrementer supplies a speed signal of 0 km/h and
the travel pulse contact controller incrementer a speed
signal of > 0.05 km/h, the event is triggered. The
activation limit is 100msec.
-Check incrementer signals with multimeter;
-Check wiring with multimeter;
-Replace speed sensor;
_1175Operation
Deviation of more than
0.25km/h between travel
impulse sensor and travel
sensor
The counts for both incrementers are compared. If the
speed signals of both incrementers differ by more than
0.025 km/h, the event is triggered. The activation limit is
100msec.
-Check incrementer signals with multimeter;
-Check wiring with multimeter;
-Replace speed sensor;
