4.
Secure the X-ray tube stator cable to the generator chassis using suitable tie-wraps or equivalent
fasteners.
5.
Perform the procedure,
Checking the Connection of the X-ray Tube Stator Cable
, described in the
following section.
2.6.4
Checking the Connection of the X-ray Tube Stator Cable
1.
Check that the stator cable (SHIFT, MAIN, COMMON, GROUND, and THERMAL SWITCH) has
been correctly connected and tightened as appropriate.
Connection errors might cause X-ray
generator or X-ray tube damage
.
2.
With an ohmmeter, measure the resistance between the Main, Common, and Shift connector pins
for Tube. Record the results in the next table.
Example Stator Resistance Measurements
Between Pins 1
& 2 (Common to
Main)
Between Pins 1 &
3 (Common to
Shift)
Between Pin 2
& 3 (Main to
Shift)
Resistance,
ohms
3.
Confirm that the results agree with the resistances documented in the tube stator datasheet
provided by the X-ray tube manufacturer.
Note:
The sum of the resistance (Common to Main) and Resistance (Common to Shift)
approximately equals to the resistance (Shift to Main). The smallest resistance should be the
resistance (Common to Main).
2.6.5
Power Line Mains
WARNING:
TO AVOID ELECTRICAL SHOCK, ENSURE THAT THE AC MAINS DISCONNECT IS
LOCKED IN THE OFF POSITION, AND THAT ALL MAINS CABLES ARE DE-
ENERGIZED BEFORE CONNECTING TO THE GENERATOR.
Refer to chapter 1 for generator power and generator power line requirements.
1.
Temporarily disconnect the fan by unplugging the fan power-connector at the fan cover.
2.
Remove and set aside the hardware securing the fan cover to the generator. Then remove the
fan cover with the fan attached.
3.
Temporarily remove the safety cover from the main fuses (if fitted). This must be reinstalled after
the AC mains connections are made, before reinstalling the fan cover.
4.
Prepare the AC mains cable as per figure 2-7 and the
AC Mains Termination Table,
and then
strip the ends of the leads to the required length.
5.
Pass the AC mains cable through the cable clamp at the upper rear of the generator cabinet,
adjacent to the main fuses. Tighten the clamps to secure the cable.
