Application / Properties

The photo-cell recognises light fluctuation.
The light fluctuation is immediately transmitted to the "load" via the
switch circuit.
In darkness the voltage on the switch circuit is held for 3-5 seconds (delay
time) so that nuisance switching by light fluctuation is avoided.
The data according to sections 3 and 4 shall be taken into account during
use.
Applications other than those described are not permissible without a
written declaration of consent from Messrs. COOPER Crouse-Hinds.
During operation the instructions stated in section 7 of the operating
instructions shall be observed.
The sole responsibility with respect to the suitability and proper use of the
photo-cells with regard to the basic requirements of these instructions
(see technical data) lies with the operator.

Installation

The relevant national regulations(e.g. Elex V, the equipment safety law for
Germany) and the generally recognized rules of engineering apply for the
installation and operation (IEC/EN 60079-14).
The improper installation and operation of the photo-cell may result
in the invalidation of the guarantee.
6.1

Mounting

The photo-cell shall be mounted on a certified protective enclosure suitable
for the application.
The correct thread must be selected.
Ensure that the thread is clean and undamaged.The Explosion
protection can not be guarantied on incorrect mounting or mounting
with a dirty or damaged thread.
The thread on the apparatus and in the Ex-d protective enclosure
must meet the minimum requirements of the IEC/EN 60079-1.
When mounted in enclosures or apparatus with explosion protection
"flameproof enclosure" (Ex-d), the wall thickness must be > 10mm.
So that the photo-cell can not vibrate loose or unscrew the thread
of the photo-cell must be screwed in completely and stuck
- with a 2 component adhesive
or
- secured with a lock nut.
To ensure the correct ingress protection a seal between the enclosure
and the photo-cell should be used.
Over tightening can lead to damage of the thread (see technical data).
6.2

Electrical connection

The electrical connection of the apparatus may only be carried out
by skilled staff and in acc. to IEC/EN 60079-14.
Ensure that the installation is isolated before installing the
photo-cell or take appropriate precautions.
Explosion-protected photo cell Ex d, GHG 640 9601 P....
For electrical connection see the wiring diagram.
The properly bared conductors of cables shall be connected with due
regard to the respective regulations.
The insulation shall reach up to the terminal. The conductor itself
shall not be damaged.
The conductor ends should be fitted with appropriate cable sleves.
The conductors shall be connected with special care.
The connecting cable must not be thermally or mechanically overloaded.
The explosion group may be adversely affected.
6.3
Before putting the apparatus into operation, the tests specified in the
individual national regulations shall be performed.
In addition to this, before being put into operation, the correct functioning
of the apparatus and installation of the apparatus shall be checked in
accordance with these operating instructions and other applicable
regulations.
If the reference pressure exceeds 20 bar, the photocell shall be
incorporated in the type test according to IEC/EN 60079-1, Section
15.2.3 (overpressure test) in accordance with the group classification
(IIA, IIB or IIC) of the respective apparatus.
The assignment of temperatures to the temperature class of the
photocell shall be laid down in the type test of the respective
electrical apparatus.
According to Directive 2014/34/EU, by definition the photocell and
the connection compartment with the photocell mounted in its wall
are component parts.
- The component parts shall be completed by a responsible person.
- As an individual functional unit, the resulting assembly is then
classified as a product and the responsible person as the manufacturer.
The improper operation of photo-cell may result in the invalidation
of the guarantee.

6.3.1 Changing the light sensitivity

The light sensitivity can set of in following steps:
04 - 11 Lux
07 - 12 Lux
10 - 15 Lux
by changing the included filter disks
Observe the pictures on page 2.
Overtightening might impair the protection category.
7
The valid national regulations for the servicing / maintenance of
electrical apparatus for use in potentially explosive atmospheres shall
be observed (IEC/EN 60079-17).
The necessary intervals between servicing depend upon the specific
application and shall be stipulated by the operator according to the
respective operating conditions.
During servicing, above all, the parts on which the explosion protection
depend, (e.g. intactness of the flameproof components, the enclosure, the
seals and cable entries).
If, in the course of servicing, it is ascertained, that repairs are necessary,
section 8 of these operating instructions shall be observed.
