Must follow – Critical information
This symbol describes safety warning of dangerous situations and indicates
necessary measures and / or appropriate precautionary measures.
Failure to comply can result in death or property damage.
Must know – Important information
This symbol describes e.g. situations that could damage the product or
devices in its vicinity, and accordingly provide appropriate action.
The sign identifies particularly important passages.

2. Product description
2.1 Product mark
CPV1038 und CPV1038*01: high performance reflex light barriers for distance monitoring tasks
using the triangulation method.
2.2 Intended use, general function and area of application
Acknowledgement of the contents of these operating instructions forms part of the intended use.
Notes and safety information must be observed in particular.
The Model CPV1038 System is
a mechanism for collision protection or distance monitoring exclusively for stationary power
driven cranes that run on a common crane track. The reflector centre on the other crane must
be situated at the optical device (lens) level.
intended for use in weatherproof applications where the direct influence of the weather is
prevented
exclusively intended for use in machinery within the meaning of the scope of EN 60204-32
(Electrical Equipment of Cranes), EN 15011 (Bridge and gantry cranes) and EN 12077-2
(Limiting devices).
When used as collision protection device, the moving crane is prevented from colliding e.g. brought
to a standstill in reference to the other crane (opposite crane).
When used as a distance monitoring device, a risk triggering approach of cranes is detected.
At least one device is required for each crane and the corresponding reflector is positioned at the
opposite wall/crane.
2.3 Incorrect use and foreseeable misuse
It is not permissible to use the device in any manner that deviates from the contents of the
operating instructions or operate it outside the prescribed areas of application.
The CPV1038 is not suitable for operation in
areas with significant challenging environmental requirements (e. g. potentially explosive
areas).
areas of excessive pollution influence where a proper function may not be ensured, despite
regular cleaning of the optical elements.
applications where normal operation due to excessive fog, excessive steam or excessive
smoke cannot be guaranteed.
systems where disconnecting the current does not lead to a safe mode.
collision protection and distance monitoring for cranes which run on a curved crane/rail track.
collision protection and distance monitoring for cranes which do not run on a common
crane/rail track.
collision protection of e.g. Industrial trucks or similar transport equipment.
use without reflector (please refer section 3)
Any technical alteration will result in cancellation of the product warranty!
System-related movement tolerances of crane system components and the possible
associated effects on the switching behaviour of the distance monitoring system
must be taken into consideration when planning crane systems.
A correct assembly and alignment of the system are essential for the correct
operation of the system’s safety function.
The set clearance distance could be reduced, e.g. by fog, steam or smoke.
During limited vision, e.g. caused by fog, steam or smoke, the function of the
distance monitoring system must be checked by moving the cranes together.
The light beam on the system must not be interrupted, for example by obstructions
or suspended objects. It is essential that proper attention is paid to this during
assembly and operation of the system.
Before commencement of work, the system’s safety function must be checked by
moving the cranes together (daily functional check).
The installation of the light barriers may only be performed by authorized technical
personnel who have the requisite professional expertise to install electrical devices on
crane systems.
The device must be immediately taken out of operation in the event of damage or leaks in
the housing, cable or line entries.
Requirements resulting from provisions relating to cranes must be applied under all
circumstances.
All different components with safety functions must be taken into account of the safety
parameters (PL, PFHd, MTTFd), e.g. an optionally required additional external power supply
or output side follow-up circuit.
Further or supplementary protective measures may be required on the basis of risk
assessments for special areas of application, e.g. restart inhibit. According to
EN ISO 13849, an automatic restart may only take place, if no hazardous situation exists.
The distancing system may not be bridged.
The crane operator and/or the crane manufacturer must be aware and comply to the
information that applies to his area of deployment; this also applies to the product, cables
and lines installation
If condensation on the reflector surface cannot be excluded for an application with high air
humidity or/and abrupt change in temperature then an anti-fogging coated reflector version
must be used. A suitable reflector type will be model 4R100BLAF or model 18R100BLAF
(see catalog of applicable documents in section 4.9).
If the device is operated in conjunction with other components such as control systems or
sensors, the corresponding user instructions must be heeded.
