not work.Press the "ON"key, voice will prompt"please connect the x-ray generator” ]
ⅲ. Parameter Setting
There are 3 parameters to be set such as kv value,time value and
delay time value.
The range of the parameter setting:
KV value : 200kv -350kv;
Time value : 0.1min -5.0min;
Press" U" key,status displays " U",it shows that the operator can set 3-digital kv value now.For
instance,input 200,LED displays 200 ,it means voltage of 200KV.
Press" H" key,status displays " H", it shows that the operator can set 2-digital time value now.For
instance,input 35,LED displays 3.5 min as time.
Press "A" key,status displays "A", it shows that the operator can set 2-digital delay-time value
now.For instance,input 12,LED displays 1.2 min as delay time,and at
the same time the delay lamp is on.
If you want to reset the parameter,you can press the corresponding
key("U" key-KV,"H" key-Time,"A "key-delay time) and re-enter them.
If the parameter setting is out of scope,press the "ON"key, voice will prompt “wrong parameter setting”,it reminds you to
reset the parameters.]
When the parameter setting were completed,press"ON"key, while voice will prompt“begin to exposure”and x-ray light is
to flash,it shows that the system is in exposure,time being reduced
constantly from preset time (the time can be set by press "H"
key)to 0.0,and the system shuts off automatically at the end of
exposure, voice prompt"exposure is over,rest”,rest process is the
same as exposure,radiating timecan last 5 minutes.voice prompt"work
is over”at the end of rest,that means exposure has been
completed.When the system is ready again, ready light will be on
,and voice prompt"ready to work”,then next exposure can be started.
The machine will enter into a state of time delay firstly if you
set the delay time before press the "ON"key.The purpose of setting delay time is to protect the operator
If the unit has been suspended for long time,it must go into
warming-up mode first before use.
Press″AG″key,it will go into aging status automatically,voice will
prompt″begin to age”,the time is to set 7.5 minutes automatically.
The complete aging procedure will run about 15 minutes,voltage ages from 200 Kv to 350KV,it lasts 7.5 minutes and
rests 7.5 minutes.
The previous procedures is complete automatically and can be
stopped by press "OFF" key at any time.
1.Warming-up(aging)from Min.kv value to Max.The procedure is not
over until the voltage value comes to Max.(350KV).
2.When aging,the unit voice prompt:aging,rest, and the ray
indicator lamp is on.
The main purpose of training unit makes X-ray tube aging so that
its service life is long,in the meantime the generator produces
X-ray,please pay attention to your protection]
If the unit get out of control in the states of exposure and aging,
such as over-voltage, under-voltage, over-current and
under-current,etc. voice will prompt,the system will turn off high
voltage automatically and return to ready state,in the meantime
corresponding protective indicator lamp will be on and indicate the
type of troubles.Press"OFF"key for clearing the trouble after you confirm the trouble type,
and then try it again.
When the tube head temperature is too high and overtemperature
indicator (OV)is flashing, now all keys are unworkable,exposure can be taken
again when the temperature return to normal and the unit return to
ready state automatically.
If time stops and displays in confusions,power supply must be cut
off immediately and check up the voltage,gas pressure of the
generator,air humidity and cables connection,after informing it
being normal, the machine can be turned on again.
This machine is composed of intelligent controller-ray generator,
power cable and connecting cable.

Introduction of Maintenance
1) Indicator lamp is not on,LED or liquid crystal can't display when
power supply has been switched on:
Check if the fan of x-ray controller is running,if not,20A or 2A
fuse may be broken or power supply plug is not plugged; if the fan
is running, the power panel or power transformer may have a
2)There is a feeling of electricity by touching controller with
hand:It proclaims that the ambient humidity may be high or some
part of the unit with the faulty insulation.
For the former cause,proper grounding is required and ensure normal temperature and
For the latter cause,non-insulated part should be checked out.
3)The system can not be ready after the power is turned on,and″ready″
indicator lamp is not on:There may be a trouble with the rectified
loop or short circuit(open circuit)of rectified output,and also may
be with output controlling board.
4)There is abnormal sound in the controller or instantaneous cut-off
after beginning of exposure or aging ①X-ray tube is leaking or
broken down.②High voltage bag is broken down.
Displays in confusions and time stops ①caused by serious discharge
of the tube head, pay more attention to aging,if necessary, check
the machine by opening the unit ;② caused by the controller being
damped,thus ventilation and drying should be taken care.
5)If power supply or high voltage is on,indicator lamp shows
confusedly,but the unit is in normal operation: Ambient humidity is
too strong and the machine is damped.
6)In the process of exposure or aging ,only"OFF"key is workable for cut off the power supply if necessary.
7)When power supply is on,20A fuse to be burnt out,Two causes account
for its occurrence:
A.Burnt out without load(generator)---some electronic component has
been broken down in rectifier bridge circuit of main loop.
B.Burnt out with load(generator)---major controlled silicon of main
loop has been broken down.
8)When system under status of high voltage or aging,a total of the
input current is
increasing near 20A,and the unit still function.it shows trouble
with rectifier bridge in main loop,one of the circuits opened.
9)After turn-off the high voltage,the system can hardly get ready
again,it shows that 5.l k resistance of main loop opened or the
electric grid fluctuation goes acutely.
10)Voltage protection when turn on the high voltage generally:
Trouble with cut–wave loop of main loop.
11)When the switch is turned on ,but fans of controller or generator
refuses to run:
①The fans is not connected to power supply,②The fans have been
damaged:③The fans are chucked by foreign matter.
12)LED indicator lamp can display other troubles.
13)Ensure not to make more serious trouble,non-professionals don’t
allowed to repair the unit.
