5.4 Allarmi
The menu Alarms of the control unit reports all the events connected to possible malfun-
ctioning of the equipment or due to external causes.
Each registration contains the reference to the concerned module, the kind of event and
its date and hour.
The module that detected the event is indicated by one of the following acronyms:
• M.C.U. (Master Control Unit)
• Combi 1 (Combiner/Divider 1)
• Combi 2 (Combiner/Divider 2)
• C.U. 1 (Control Unit TX1)
• C.U. 2 (Control Unit TX2)
The type of event allows to identify the origin and the consequence of the fault. The first
letter of the type of event can be one of the following:
W “Wait” event that causes the temporary block of the piece of equipment that will
be removed as soon as the problem is solved.
R “Retry”, event that causes a temporary block of the piece of equipment, that will
effect a restart attempt after a fixed lapse of time. (Max. 8 attempts)
F “Fault”, event that causes the block of the equipment and requires the intervetion
of an operator for the restart.
E “Error”, event that doesn’t cause the interruption of the supply of power, but can
reduce the functions of the equipment (e.g cannot be done the changeover fun-
ction of the exciters).
D “Derating”, The transmitter has activated derating. The alarm derating may occur
on the MCU module (system derating see Section 5.4.1) or on Form CU x (dera
ting of single machine, refer to the manual PJ10KPS-C).
The possible event types are listed in the table below.
Code Meaning
Master Control Unit
