11 EPS-AC ALARM LIST
11.1 ANALYSIS OF ALARMS DISPLAYED ON CONSOLE
Here is the alarm list
11.1.1 One blink alarms
1)
MICRO SLAVE KO
Cause:
When no number is specified it means the Master Microprocessor
(MM) has detected a status signal coming from the supervisor (SM)
that dos't agree with the present comand values. In fact in real time
MM and SM compare the command (tacho-generator, stepper
motor, limit switches, automatic request) they are reading. When MM
is reading a command value different from the one the SM is
reading, this alarm occur.
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic.
2)
MICRO SLAVE #1
Cause:
Means the SM has detected a lacking synchronisation pulse. MM
generates a continuous a synchronisation pulse (every 16msec) to
run an interrupt service routine reading the command on the SM.
When this synchronisation pulse is missing for more than 100msec
this alarm occur.
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic.
3)
MICRO SLAVE #2
Cause:
Means the SM has detected the safety contacts closed prior to being
commanded.
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic.
4)
MICRO SLAVE #3
Cause:
Means the SM has detected an analog status signal coming from the
MM -and replying the SP POT- frozen while the SP POT is changing.
(Only for two pots steering).
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic.
5)
MICRO SLAVE #4
Cause:
means the SM has detected the motor turning direction is opposite to
the present command. (Command and action disagree. Only for two
pots steering and automatic centering).
Remedy:
If the alarm occurs systematically, it is necessary a logic substition.
