11 EPS-AC ALARM LIST

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.
If the alarm occurs permanently, it is necessary to substitute the
logic.
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.
If the alarm occurs permanently, it is necessary to substitute the
logic.
Means the SM has detected the safety contacts closed prior to being
commanded.
If the alarm occurs permanently, it is necessary to substitute the
logic.
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).
If the alarm occurs permanently, it is necessary to substitute the
logic.
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).
If the alarm occurs systematically, it is necessary a logic substition.
