User & Technical Manual
Rev. 1.5 - 08/02/06
In addition to the contactors that permit the soft-start function, this unit control the
cooling blower function. This is switched on together with the On command, while,
when the equipment is in OFF mode, the blower relay stops to be driven after about
4 minutes. This laboursaving device is used to avoid that temperature peaks to be
present at the internal of RF modules. This procedure of post-ventilation is used for
all conditions of equipment stops, both in case of human will or in case of alarm .
Table 7.1 contains a schematic of the output of the power supply section. The graphic
display of the contactor status during the time is reported in the Picture 7-16.
7.3.2 Configurations
The power supply section of the PJ5KPS has the following configuration possibilities:
1 Equipment with single power supply carriage
2 Equipment with double power supply carriage
3 Equipment with automatic reset of the Safety function at the emergency button
release
4 Equipment with reset of the Safety function to be done manually by pushing the
button.
The standard configuration of the equipment includes the points 1 and 3.
7.3.3 Logic control Signals
The power supply section of the PJ5KPS constantly controls the logic signals that
can be divided in general signals (related to the equipment in its complex) or carriages
signals (related to the single power supply carriages). The status of these signals
can be checked on the Power Supply Menu in the control unit.
When a fault is detected in one of the general signals, the PJ5KPS is blocked either
temporarily blocked or until the intervention of the maintenance staff, depending on
the type of signal. The general signals with relative meaning and managing mode
are the following:
Signal
Function
Safety
This signal in alarm status when the emergency button is pushed. In
this case the feed line to the several contactors is immediately
sectioned, per cui si ha un arresto istantaneo di tutte le parti soggette a
potenza; the exciters remain however operational.
In the meantime a signal send a message to the control local unit of the
current conditions. To restore the funtionning of the equipment the
emergency button has to be reload.; if the equipment is configurate in
mode 3), the start-up cicle is activated after two seconds. If the power
supply is configurated in mode 4) it will be necessary to push the
SAFETY RESET button to restart the equipment. The safety signal is
not memorized on the events menu.
