2.Device description
Intended use
The device is intended to be used in medical diagnostic applications with restrictions to human
diagnostics. The device is intended to be used as accessory of an X-ray system in a professional
healthcare facility environment. The device is intended to restrict the dimensions of a diagnostic X-ray
field by limiting the primary X-ray beam. The limitations of use are specified in §2.7. The device is not
intended to be used in fluoroscopy applications; near active HF Surgical Equipment or in the RF
shielded room of a system for magnetic resonance imaging, where the intensity of Electromagnetic
Disturbances is high.
Use, other than above, is identified as abnormal use.
The intended user of the device is defined as the operator of an X-ray system. The operator shall be
qualified and/or trained to operate the X-ray system.
Description of the collimator
The collimator is an automatic, square-field, multi-leaf, X-ray collimator and is suitable for installation
on stationary X-ray equipment.
The collimator mounting plane is intended at 80 mm (3.14") from the focus of the X-ray tube.
The X-ray field is limited by 4 pairs of shutters which are covered with lead.
Two pairs of lead shutters are located near the focus of the X-ray beam; two pairs are located near the
exit window of the collimator. The latter shutters serve to accurately define the X-ray field edges.
The main electronic system consists of a single PCB (Collimator main board). This board provides the
motorized positioning of the shutters which are controlled by two stepper motors and positioned by the
intended users.
The X-ray field can be adjusted manually with the two knobs (30/40 Series only) on the collimator front
panel or remotely. The field size can be selected with SID and field dimension input, see the applicable
User Manual.

Use of the measuring tape:
The type of measuring tape used is a standard measuring tape. The tape used in the
collimator starts with values that correspond to the focus/collimator lower edge distance;
maximum measurement with the tape is 2 m.
Forcing and/or extending the tape beyond this point could cause the following
inconveniences:
•Breakage of the tape or,
•Distortion of the tape or,
•Impossibility of retracting the tape into its housing.
NOTE: Do not extend the tape beyond the indication of 2.0 m
NOTE: High speed release of the tape might damage the tape

Aluminum equivalent
The Aluminum equivalent (or ATTENUATION EQUIVALENT) can be found on the product label. The
location of the product label can be found in §9.2. The ATTENUATION EQUIVALENT is expressed in
[mm] aluminum.
Restrictions on use
RF communication devices should be kept at a minimum distance of 30 cm. Otherwise the
performance of the device can be negatively influenced.
Essential Performance
The Optica 30/40/50 series does not have essential performance.
Applied parts
The Optica 30/40/50 series do not have applied parts.
Known contraindication(s)
Contraindications of the X-ray system continue to apply (see X-ray system documentation).
Additional the Optica 30/40/50 series introduces matter in the primary X-ray beam which primarily
results in additional X-ray scatter. Additional X-ray scatter causes a radiation risk. The Optica 30/40/50
series is mitigating the radiation risk by shielding the additional scatter and limiting the size of the
primary X-ray beam and also confining the scatter generated from the X-ray tube (housing).

Figure 1 Rear cover screws
Installation of cables
Cables for power supply and CAN bus must be connected to the green CAN bus connector that is pre-
assembled inside the collimator (see §1.8). The connector can be reached when the rear cover of the
collimator is removed (see §3.5 for instructions). The instructions for electrical isolation (see chapter 4,
Electrical ) shall be taken into account.
WARNING: Disconnect power supply before opening collimator.
WARNING: To avoid electromagnetic interference, follow the cable specification!
WARNING: Cables and terminals used for the connection of the collimator must be
suitable for operation at temperatures of 70 °C.
WARNING: Incorrect power supply could damage the electronic timer and/or the lamp
and/or electrical motor DC/Stepper.
WARNING: Collimator supply is protected by a fuse. See §4.1
WARNING: Power supply cable must be designed to carry the collimator supply current
and should meet IEC60601-1 requirements
CAN bus interface cable requirements
•Shielded cable, twisted wires, data pair and one common
•Cable size: The supplied strain reliefs (See §1.8) will fit round cables with a diameter of
approximately 5,6 - 7.4 mm.
CAUTION: The maximum length of the CAN bus interface cable depends on the selected
CAN bus baud rate. Cables may not be longer than is defined in the CAN bus standard
otherwise unpredictable behavior may occur.

Figure 2 Collimator power supply cable and CAN cable installation
Steps to install the power supply cable and (if needed) the CAN bus interface cable, see Figure 2 for
part explanation.
Remove the rear cover according instructions in §3.5.
Remove the green CAN bus connector
Feed the cable through the rear cover.
Remove a Blind plug
Apply a strain relief as supplied in the Accessory kit (see §1.8) on the power supply cable.
Feed the power supply cable through the strain relief bracket.
Strip the power supply cable
Connect 24 V and 0 V wire to the green CAN bus connector, according to the pin assignment table in
the section below.
Connect earth wire to the protective earth terminal.
Note: When the CAN bus cable also needs to be installed, follow the instructions
described below otherwise move on to step 9
1. Feed the CAN bus interface cable through the rear cover.
2. Feed the CAN bus interface cable through a strain relief as supplied in the Accessory kit (see
§1.8).
3. Feed the CAN bus interface cable through the strain relief bracket.
4. Strip the end of the CAN bus interface cable
Note: Strip length of the cable insulation must be accordingly to connect the cable
shielding to the grounding clamp
5. Connect the CAN bus interface cable to the Green CAN bus connector according to the pin
assignment table below.
6. Re-mount the green CAN bus connector
7. Mount the CAN shielding grounding clamp
8. If a CAN termination resistor is needed: Set the jumper on the Connection board between pin
1 and pin 2, see Figure 3.
9. Mount the strain relief(s)
10. Ensure that the protective earth terminal (see Figure 3) is properly connected to the safety
earth line.
11. Close the rear cover according instructions in §3.5.
