User & Technical Manual

Mains
This signal is generated by an external device that control that the
power supply current meets the limits of the functionning and that the
R,S,T direction of progression of the phases is correct. If the mains is
on alarm status, The equipment stops working , including the feeding of
the exciters. When the signal return , an automatic restart occurs. All
the time that an alarm of this type is present , a relative message in the
menu alarm of the control unit is memorized.
Air pressure
A pressure sensor informs the local unit if the cooling air flow is not
correct ; the intervention of the sensor stops the equipment temporarily
with the disconnection of the power supply contactors of the power
transformers . When the signal returns an automatic restart of the
PJ5KPS takes place. An opportune message is memorized in the
Alarm menu in the control unit of the unit all the times that this signal
interveens.
Blower Motor Protector
The intervention of the ground protection of the motor protector put the
equipment on Fault mode. This condition requires the presence of an
operator to restore the functionning of the equipment . In order to
attempt to restart it's necessary to reload the motor protector and push
the ALARMS RESET of the control unit . Each time that this signal
interveens an opportune message is memorized in the alarm menu of
the control unit.
The “carriage signals” are related to the status of the single carriages. A possible
alarm status in one of these signals has a different effect on the transmitter depending
on the number of the included power supply carriages, single or dual. While in the
first case the PJ5KPS is stopped in case of a fault, in the second case the spare
carriages is still able to supply all the required power; in this case the fault is signaled
by the LED Warning on the front panel.
The meanings of the carriage signals are the following:
Signal
Function
Fuse 1
This signal, meaning “Carriage 1 Fuse” signal is in fact composed of the
series of all the safety interlocks of the carriage. If this signal is in the
alarm status, it will be necessary to determine which of the following
possible reasons is causing it: AC power fuse, microswitch of the chart
connected. The magneto-thermic switch , command connector coils,
control signals connector , threephase power connector.
Trafo 1 OH
This signal, meaning "Overheating transformer 1" (Trafo 1 Over Heat), is
connected to the safety thermal switches. There are two different
sensors: one is on the transformer lamelIar plate, the other is on the
rectifier heat dissipator. The intervention of one of these two devices
stops temporarily the equipment on WAIT mode. When temperature
goes below the threshold, the transmitter will automatically restart.
The temperature of intervention is 90°C, and in case this alarm arises, it
will be recorded with a message in the alarm menu on the control unit.
Fuse 2
As Fuse 1, for carriage 2
Trafo 2 OH
As Trafo 1 OH, for carriage 2
If the signal Fuse X is on alarm, in order to restore the regular functionning of the
equipment it is necessary to identify the cause of the fault. The following table resumes
the points to be verified in order to find the cause of malfunctionning :
