6.1 - General
The Pro-Dialog+ control system has many fault tracing aid func-
tions. The local interface and its various menus give access to
all unit operating conditions. If an operating fault is detected,
an alarm is activated and an alarm code is stored in the Alarms
menu, sub-menus CUR_ALRM and ALARMRST.
6.2 - Displaying alarms
The alarm LED on the interface (see chapter 4.1) allows the
quick display of the unit status.
• A ashing LED shows that the circuit is operating but
there is an alert.
• A steady LED shows that the circuit has been shut down
due to a fault.
The ALARMRST menu on the main interface displays up to ve
fault codes that are active on the unit.
6.3 - Resetting alarms
When the cause of the alarm has been corrected the alarm can
be reset, depending on the type, either automatically on return
to normal, or manually when action has been taken on the unit.
Alarms can be reset even if the unit is running.
This means that an alarm can be reset without stopping the
machine. In the event of a power supply interrupt, the unit re
-
starts automatically without the need for an external command.
However
, any faults active when the supply is interrupted are
saved and may in certain cases prevent a circuit or a unit from
restarting.
A manual reset must be run from the main interface via the
ALARMRST menu, item RST_ALM. Depending on the congura
-
tion in the GENCONF menu, access to the item may be protected
by a password.
