0. Prefaces

The Tld-irradiator MODELS 2210 is a versatile calibration system and serves
the calibration of TLD chips, - sticks with 2, 3 or 4 elements.
For this is a Sr90/Y90 radiation source used by 33 MBq (0.9mCI) with an
activity.
The equipment can be operated both at a 230V/50Hz and at a 115V/60Hz
alternating voltage system.

1. Range of application

TLD-Irradiator is built in a portable condition housing.
The front side of the housing contains the following modules from on the left of to the right:
-the electronic tax and control unit
-the thrust subject
-the calibration factor announcement.
On the back is a cold equipment installation plug in combination with the in out rocker
switch, the safeguard subject and the voltage switch as slidegate valve.
On the front side of the tax and control unit are LED displays:
-One also,,power” designated green LED, which indicates whether the
equipment is switched on .
-One also,,more shutter” designated white 3-Farben-LED-Anzeige to
optical control of the Device status.
-A tracer with the designation , is started ,,start” which procedure the
calibration.
On the right side of the equipment are the thrust subject and the counter.
The thrust subject can be equipped with carrier disks. There are 3 different types:
-Combination disk for 50 chips and rods
-Disk for 50 micro cubes
-Disk for 5 TLD maps
On the front of the counter are keys for adjusting the counter value.
Example: During a mains voltage of 230V/50Hz the disk turns in the Irradiator
with a speed of 1 revolution/minute.
If 90 revolutions are necessary for the irradiation, the counter desired value must
be adjusted to 90.
The counter counts the revolutions by a pulse generator and increases its actual value around
1 by each impulse .
If the counter resembling and the output contact are the same the calibration procedure
switches off. The carrier disk in the thrust subject is located in basic position, the LED
display, shutter shines green and an acoustic signal sounds.
The counter desired value of the input field should indicate at least the value to 1.
The carrier disk can be taken off after opening the thrust subject. After pressing of the key,
,,reset”at the counter the equipment is ready for a further calibration procedure.

2. Technical manual

During the calibration procedure the disk, propelled by an alternating current synchronous
geared motor, turns with the elements which can be illuminated continuously under the
opened source screen.
With a frequency of 50 cycles per second the speed 1 rotation / minute is.
With a frequency of 60 cycles per second the speed 1.2 rotations / minute is.
If one opens the thrust subject during the process, the drive stops, the source screen is closed.
On the back a cold equipment installation plug is combined with an in out rocker switch.
Here furthermore is a safeguard subject with two contact-voltage-proof fuse holders inserted.
At a mains voltage change over switch are the tensions 230V/50Hz and 115V/60Hz
selectable.

4. Manual
Caution
Please read the manual carefully and completely, before you take the equipment in
enterprise!
4.1 Safety precautions
Caution
The equipment corresponds to the relevant safety regulations.
Repairs may be accomplished only by authorized specialists!
Inappropriate repairs can result substantial dangers for the user, for which
the manufacturer is not responsible!
If the equipment is purpose-alienated used, the manufacturer takes for this no
guarantee!
Attention
Before start-up examine whether the mains voltage indicated on the tension selector
switch agrees with your local mains voltage.
Operate the equipment only standing on an even and horizontal surface.

In order to serve duly the equipment, first is to be clarified it, which kind of Tld elements
are to be calibrated.
If it concerns TLD maps, then the photograph plate is to be used for maps (card disc). Five
maps can be put, with the map corner outward, on the plate. Two dowel pins prevent that the
maps shift during the rotation.

4.2 Operating instructions

When TLD chips and/or. TLD- sticks are calibrated, you take the plate with the blind
holes arranged at the edge (combi disc), into which the elements are to be put down.
Then the thrust subject is put to be pulled out up to the notice and the appropriate plate is put
on the thorn. It is to be noted that the follower pin of the equipmentfirm mother board sits in
the groove of the plate. Otherwise the plate is to be turned so for a long time, until the pin
engages.

The next step consists of stopping by means of the shown table the calibration factor at the
counter.

The determined desired value can be entered by the appropriate manipulation of the keys at
the counter. After effected input those, the ,,reset" key is to be pressed in order to put the
counter exit back.
Input errors can be repaired by the repetition of the procedure.
After effected input of the desired value the calibration process is started by the short
manipulation of the push-button ,, start ".
At the same time with the start of the engine the source screen is opened by electromagnets.
The change of the color the white LED with the designation ,,shutter "in yellow indicates that
the source screen opened duly.
While the counter in the large display indicates the revolutions already accomplished to the
calibration, while in the small display the total calibration factor is indicated.
The calibration process is terminated automatically, as soon as the actual value corresponds to
the desired value. Those,,shutter"- LED lights up green and an acoustic signal sounded. This
means that the source screen is closed and the carrier disk stands in zero-position.
The acoustic signal can be switched off by the manipulation to that ,,reset "- key at the
counter. At the same time the counter is put back.
12
Note
Calibration data for other dosimeters and/or plates can be determined easily with an
TLD-analyzer (e.g. Harshaw model 4000 TLD).

If the red, lights up ,,shutter”-LED announcement with the start of the calibration process, the
source screen did not open. Repeat the starting process after the equipment were completely
switched off. If the Irradiator does not show the desired reaction after renewed switching on
and operation of the push-button, please inform the service.
Those, changes ,,shutter”-LED announcement on red, to the completion of the calibration
procedure the source screen was not closed. Usually this error can be repaired by switching
off and renewed switching on of the equipment on. Should be nevertheless still indicated after
switching on of the errors on, expressly it is pointed out that the equipment may not be
opened under any circumstances by unauthorisiertem personnel! From the opened
radiation source substantial dangers can result, for which the manufacturer is not
responsible! Please you contact the service immediately, which then will you inform
about the further steps.
During the calibration process if the thrust subject is opened, the process is interrupted and the
source screen is closed. After latches of the thrust subject and press that ,,start”- key the
procedure is continued.

4.3 Error recognition and recovery

This section contains measures and data for maintenance of the equipment.
The equipment is to a large extent maintenance-free implemented.
5. Wartung
5. Wartung
Examine the equipment on:
a. outside damage such as notches, tears, deformation, abrasion and corrosion.
b. bolt connections for tightness.
c. completeness.
d. conductions for break and abraded positions as well as for aging of the isolation.
e. electrical patch cords on damage and corrosion as well as for tightness.
The equipment may be only cleaned with a mild cleaning solution and a dampened cloth. It
may not arrive under any circumstances to humidity into the controls.
As an integral back-up battery secures the calibration at power breakdown up to 10 years, the
counter has to be exchanged after the expiration of this time. The supply voltage of the
counter must be checked before installation. The exchange sould be done by the manufacturer
of the device.

5. Maintenance
Caution
The equipment may be waited only by instructed and entitled personnel.
Before opening the equipment it is to be guaranteed that the power supply plug pulled and
the equipment is unstressed!
The sealed screws of the source cover may be loosened under no circumstances.
This may be accomplished only by the authorized personnel of the equipment
manufacturer!
