8. LIGHTS

8.1. Principle of Operation

The  controller  has  two  0-10V  outputs  that
can  be  used  to  control  the  light  intensity.
Additional  lights  can  also  be  connected  to
the  On/Off  relays:  the  on/off  lights  simply
turn on when the 0-10V light output is on.
Refer to section 4.4 to enable light programs
and refer to section 4.7 to assign the  on/off
light relays.

Light Programs:

The controller can use 9

different light programs containing 6 daily
cycles each. The same program is performed
every day until another program replaces it
(the program selection is made according to
the animal age).

Light Cycles:

Up to 6 daily light cycles can be

performed in the course of a light program.
These cycles are used to change the light
intensity over the day (see graph below).

Light Peaks:

A light peak is a marked increase

in the light intensity. They are used to stimu-
late the animals. When light peaks are used,
they are performed right after the sunrise, at
the very beginning of a light cycle and are
then performed on a regular basis, according
to a user-defined timer.

* Accessible if the light output is enabled in the Set-

up menu (see section 4.4). A password may also be

required to access it (see section 4.2.1).

A graph showing the current status of the
ongoing light cycle is displayed along with
the light parameters.

Set the following parameters:

Make sure you have selected the right
light program before adjusting the fol-
lowing parameters.

Age —

Select the animal age at which the

chosen program starts. This value ranges
from -5 to 450 days (negative values are

Lights 24hr —

Select

“Yes”

for the lights to

stay lit all day long; select

“No”

to use the

light cycles.

Use Peaks —

Select

“Yes”

to use light peaks at

regular intervals or select

“No”

to disable them.

Sunrise —

When a cycle starts, the light

intensity increases from its minimum to
its maximum intensity over this delay (see
previous graph). Set the sunrise delay to the
desired value (from 0 to 60 minutes). *

This

parameter is accessible if the “Lights 24hr” option

is disabled.

Sunset —

When the stop time of a light

cycle is reached, the light intensity gradually
decreases from its maximum to its minimum
intensity over this delay (see previous graph).
Set the sunset delay to the desired value
(from 1 to 60 minutes). *

This parameter is ac-

cessible if the “Lights 24hr” option is disabled.

Number of Cycles —

Select how many cycles

must be performed in a light program. It
ranges from 1 to 6 cycles. *

This parameter is

accessible if the “Lights 24hr” option is disabled.

Adjust —

Select the desired light cycle. The

following parameters are related to this cycle:
