[ 3 ] TUBE HEAD THERMAL CHARACTERISTICS
A. Interval between each exposure
The temperature inside of the tube head rises when an exposure is made. The value of the heat
generated is measured in Heat Units (HU), which is the product of tube potential, tube current
and exposure time. Excessive heat will accumulate inside of the tube head if the x-ray is used
without a proper cool down interval between each exposure. The excessive heat may damage the
x-ray tube, high voltage generator or both.
B. Duty cycle
A cool down interval of 30 seconds or more must be allowed between each 1 second exposure.
(a 15 second cool down must be allowed between each 0.5 second exposure.) This will avoid
the accumulation of excess heat and prolong the tube head life.

[ 1 ] SUPPORTREQUIREMENTS
Main Controller :
The main controller of model 505 is designed for mounting
on wood studs with three lag screws (ø 9 x 75mm). The wall
and mounting hardware must be sufficient to withstand a 45kg
shear load and a 200kg withdrawal force at each of the three
mounting screws. When using concealed wiring, a flush mounted
junction box with the necessory conduit and wirong must be
pre-installed at 1165mm from the floor.
Sub Controller :
When mounting the model 505 sub controller, the wall and mounting
hardware must be sufficient to withstand a 4.5kg shear load.
If the PHOT-X IIs505 is to be mounted in a manner other than
what is specified in this manual or if the hardware to be used is other
than what is supplied, the support capability of the wall and the
strength of the hardware must be checked and verified to be adequate.
[ 2 ] ELECTRICAL REQUIREMENTS
Power supply :
The model 505 x-ray system is operated on a power supply of rated line voltage ±10% with a thre
wire (hot, neutral, earth) circuit, separately connected to the central distribution panel with an
over current protection device. Use a flexible cable approved by CEE (13) 52 or 53 consists of
0.75 mm2 or 1 mm2 conductors. Diameter of the sheath of cable should be 6 ~ 7.5 mm diameter.
Line voltage regulation should be within the range of 0 ~ 5% (for 100V, 110V, 120V type) or
0 ~ 3% (for 220V, 230V, 240V type) at rated current.
Interconnecting wiring between main controller and sub controller :
4 conductors, 0.5 mm2, 300V is recommended. Maximum wire run distance is 10m.
Concealed wiring :
Route conduit and wires through wall and into (2) flush mounted junction boxes located (1)
behind the main controller and (1) behind the sub controller. Recommended heights above the
finished floor for the flush junction boxes are : 1165mm for the main controller and 1310mm
for the sub controller. Wiring done in this manner should extend 300mm beyond the wall surface
to allow sufficient wire for connections.
Note : All connections, workmanship and materials used must comply with the local codes.

(Fig.3-17)
6. Loosen the (M5 x 10mm) screw and remove
the nylon cable clamp from the yoke housing.
Place cable clamp on the balance arm cable.
Connect the 10P connectors, and then attach
the balance arm cable to the yoke housing
with the nylon cable clamp. (Fig.3-18)
7. Reattach the yoke inside cover with the screw
(M4x 15mm). Before closing the cover,

[ 5 ] SUB CONTROLLER INSTALLATION
The wall and the strength of the hardware used must be checked and verified as being adequate to
withstand a 10 pound (4.5kg) shear load. A flush mounted junction box with the necessary conduit
and wiring should be pre-installed at 51-5/8" (1310mm) from the floor.
1. Remove two (M3 x8mm) screws from the under side
of the controller and open the front panel. (Fig.3-19)
2. Disconnect the 4P connector from the timer PC Board.
(Fig.3-20)
3. Route the interconnecting wires from the main
controller through access hole of chassis and
mount on the wall with four (ø4.1 x 20mm) wood
screws. (Fig.3-20)
4. Cut 4 interconnecting wires from main controller
to a workable length. Strip 3/16" insulation off
the wires and connect them to the 4P terminal
block.Terminal number for each wire should be
matched to the terminal number in the main
controller. (Fig.3-21)
Miswiring causes permanent damage to both
timer PC board and power PC board.
5. If wire length is too long, push it back into the access
hole of the wall. This will prevent mechanical damage
to the timer PC Board when replacing the front cover.
6. Reattach the 4P connector to the timer PC Board.
(Fig.3-20)
7. Set the pins located on the upper side of the front panel
into holes on the top of chassis and attach the front
cover to the chassis with two (M3 x 8mm) screws.

[ 6 ] HAND EXPOSURE SWITCH (OPTION)
An optional hand exposure switch can be connected
tothe sub controller. Since this exposure switch has a
coiled cord, operator can stand the most suitable 
position forRperation.
The exposure switch on the front panel of sub
controller and this hand exposure switch can be used. 
If local code prohibits use of both switches,
disconnect the connector of either one of the switches.
1. Confirm the contents of optional hand exposure
switchkit. (Fig.3-23)

4. Insert the bushing of coil cord into the slot at the
bottom of the chassis, reattach the front cover
andsecure two (M3 x 8mm) screws again.
(Fig.3-24)
5. Place the hook on the top corner (right or left)

[ 7 ] EXTERNAL INTERLOCKS (NOT SUPPLIED)
If the external interlock for preventing from starting  to
emit x-radiation or to stop emitting x-radiation is used, the
interlock switch should be inserted in #3  terminal of 4P
terminal block either in the main  controller or in the sub
controller. If this interlock switch is opened, emittion will
bestopped. It is recommended to indicate the state of

SECTION 4 : POST INSTALLATION INSPECTION
[ 1 ] ARM ASSEMBLY
1. Incorrect leveling of the wall plate and wall bracket can cause arm drift. First, check leveling
with horizontal arm in position #1. (Fig.4-1) If not correct, bracket must be adjusted by
placing shims behind the wall plate.
IMPORTANT :
If the end of the horizontal arm shown in position #1 is pitched below level, then the tube head
will drift away from the wall. If the end of the horizontal arm in position #1 is pitched above
level, then the arm will require only minimum adjustment of the brake screw. (Fig.3-13)
2. Check leveling in position #2. )f not correct,
adjustHorizontal Arm as follows : (Fig.4-1)
a. Slightly loosen two top mounting bolts for arm
mounting bracket.
b. Shift the bracket left or right until the arms are
accurately leveled.
c. Move the horizontal arm to position # 1.
d. Fully tighten two top mounting bolts.
e. Fully tighten bottom mounting bolt.
NOTE : Slight tendencies to drift can be corrected
by tightening brake screw in horizontal arm.
Do not tighten beyond what is required to
prevent drift.
[ 2 ] BALANCE ARM TENSION ADJUSTMENT
1. Place the balance arm assembly into position.
2. If either balance arm drifts higher or lower from
the set position, remove the spring adjuster cover
and adjust the balance arm spring tension with
the balance arm wrenchSUPPLIED. (Fig.4-2)
[ 3 ] HEAD POSITIONING
A. Place head into position.
B. If head drifts from the set position, adjust the
BRAKEscrews according to the following
procedures.(Fig.4-3)
1. Loosen the yoke side cap screw (ø3 x 8mm
tapping screw) and remove the yoke side cap.
2. Adjust the six brake screws using a screw driver.
3. After adjustment, reATtach the yoke side cap and screw.

Including these two speeds, PHOT-X IIs 505 x-ray can provide 16 different filmVSHHGV
(F.00 ~ F.15) and any two of them can be programmed for easy selection. If doctorXVHV
a different film speed, or prefers darker (or lighter) radiographs, the new speed can be
programmed as follows. Higher speed settings make films darker. If film speed is
increased by 1, exposure time becomes 25 % longer.
1. Keep the kV selection switch and mA selection switch depressed simultaneously for
more than 3 seconds. Release the switches if the ready light starts to flash.
