3.2 GENERATORS WITH LF-RAC (LOW SPEED STARTER)
3.2.1 STATOR VOLTAGE AND CAPACITOR SELECTION
Check that the capacitor value of the Low Speed Starter
corresponds to the value recommended by the X-ray Tube
manufacturer. If needed replace the capacitor. Also, the Rotor
speed must be indicated by the manufacturer.
The DC Brake of the Low Speed Starter (LF-RAC) can be removed by
desoldering CR6 on the LF-RAC Board (refer to schematic 543020xx). In this
case, the Tube will remain coasting after releasing the “Prep”orthe“Fluoro”
order.
3.2.1.1 CONFIGURATION FOR ONE OR TWO TUBES WITH STANDARD STATOR
Voltage and capacitor is factory set to 220 VAC, 30 μF. In all cases, refer to
X-ray Tube Product Data.
3.2.1.2 CONFIGURATION FOR ONE OR TWO TUBES WITH THE SAME STARTING VOLTAGE AT
110 V AC
When the stator requires a starting voltage of 110 VAC (a.e. X-ray Tube Toshiba
E7239 / E7240 / E7242 / E7252 / E7299 / E7813 / E7865) perform the following
modifications:
• If the Power Input Transformer 6T2 is for using with power lines up to
240 VAC (part number 50509030), remove the wire labelled as “4” that
is connected to Terminal 4 (230 VAC RTR) and connect it to Terminal 3
or8(110VAC).
• If the Power Input Transformer 6T2 is for using with power lines up to 530
VAC (part number 50509029), remove the wire labelled as “4” that is
connected to Terminal 4 (230 VAC RTR) and connect it to Terminal 40
(110 VAC).
• For X-ray Tube Toshiba E7252 or E7813 (or when it is required) replace
also the Fuse F1 (6A) on the LF-RAC Board by another fuse of 10 A.
These changes affect to all the Tubes connected to
Generator.
