7.1 - General
The Touch Pilot control system has many fault tracing aid
functions. 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 “Reset alarms” and “Current alarm”.
7.2 - Displaying alarms
The alarm icon on the interface (see chapter 4) allows the
quick display of the unit status.
•
A flashing 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 “Reset alarms” menu on the main interface displays up
to five fault codes that are active on the unit.
7.3 - 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
restarts 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 touch screen interface
or the web via the “Reset alarms” menu, item RST_ALM.
Alarm reset can be protected by a basic user level password.
7.4 - Critical alarms
Certain alarms linked to the frequency variator are considered
as critical (see chapter 7.5.2 - Variator alarm sub-codes).
These alarms can only be cancelled if the user is connected
as an advanced user. If an alarm of this type is triggered,
contact Carrier Service.
