GENERAL
1. INTRODUCTION
The VLC-3 is a light program controller designed for livestock buildings.
Light intensities vary according to a light program sequence. Up to 12
dusk-to-dawn programs and 20 light peaks can be programmed per
period with up to 20 different periods in one year. The controller
includes a four-digit display, function pilot lights, two adjustment knobs
and a push-button for easy programming. Additional features include:
- gradual increasing and decreasing of light intensity to simulate
sunrises and sunsets
- minimum and maximum intensities specified as a percentage of full
lamp intensity
- display of current time, day, light intensity and period
- step-by-step programming
- minimum inertia method used to smooth sudden transitions in light
intensity
- manual mode
- a lamp output activated above or below a threshold value
- an alarm output
- a real-time clock with backup battery for keeping time in case of a
power failure
- overload protection on the output
- a 115/230 VAC - 50/60Hz power supply
- the unit can be connected to a computer communications module

VLC-3 rev.04
VLC-3
2. PRECAUTIONS
Although fuses at the input and outputs of the controller
protect its circuits in case of an overload or overvoltage,
we recommend installing an additional protection device
on the controller's supply circuit.
The room temperature where the controller is located
MUST ALWAYS REMAIN BETWEEN 32°F AND 104°F
(0°C TO 40°C).
To avoid exposing the controller to harmful gases or
excessive humidity, it is preferable to install it in a
corridor.
DO NOT SPRAY WATER ON THE CONTROLLER
3. MOUNTING INSTRUCTIONS
Open the latch on the right and lift the cover. Mount the enclosure on
the wall using four screws. Be sure the electrical knockouts are at the
bottom of the enclosure in order to prevent water from entering the
controller. Insert the screws in the mounting holes provided and tighten.
Fasten the black caps provided with the controller onto the mounting
holes.
5
VLC-3 rev.04
VLC-3
ALL WIRING MUST BE DONE BY AN AUTHORIZED ELECTRICIAN AND MUST COMPLY WITH APPLICABLE
CODES, LAWS AND REGULATIONS. BE SURE POWER IS
OFF BEFORE DOING ANY WIRING TO AVOID ELECTRICAL SHOCKS AND EQUIPMENT DAMAGE.
4. CONNECTIONS
To connect the controller, refer to the wiring diagram enclosed with this
user's manual.
Set the voltage switch to the appropriate voltage.
Use the electrical knockouts provided at the bottom of the enclosure. Do not make additional holes in the enclosure, particularly on
the top of the enclosure when using a computer communications
module.
Two types of alarms are currently available on the market. The first
type is activated when current is cut off at the source; the other is
activated when current is supplied to the input. Use the NC terminal
for an alarm of the first type; otherwise use the NO terminal.

5. LOCATION OF THE CONTROLS
The pilot lights on the left indicate which function is currently active on
the digital display. When the function has a corresponding value associated to it (for example, Start Time), the value appears on the display.
The function selector changes the current function. The adjustment
knob is used to adjust the currently displayed parameter value. The Day,
PM and % pilot lights to the right of the display indicate the unit of the
value currently displayed. If no user activity is recorded after one
minute while inside a function other than CLOCK or MANUAL MODE,
the display returns to the clock time.
Internal Switches: located inside the front cover.

When switch #1 is ON, the timer parameters are locked and can only be
displayed (except the clock time). When switch #2 is ON, the display
shows 24-hour time. Otherwise, the display shows 12 hour time (AM /
PM). Use switch #3 to select a curve (ON = fluorescent curve, OFF =
incandescent curve). The switch #4 determines the output operation
mode (ON = 1-10V, OFF = 0-10V). The switch #5 determines the
progression of lights intensity on manual mode. The switch #6 determines whether the sunset is performed before or after the Stop Time
(ON= before the stop time, OFF = after the stop time).
6. OVERVIEW
Notes:
(i) The minimum programmed intensity, sunrise duration and sunset
duration are common to all light programs.
(ii) Peaks are programmed separately for each period using a start time
and a duration and assume that the current intensity is at its maximum
programmed intensity. If this is not the case, the peak is not executed.

(iii) Light intensity between programs never drops below the minimum
programmed intensity.
(iv) The slope of the transition curve is exponential rather than linear so
that the perceived transition in light intensity is equally distributed over
the duration.

USING AND PROGRAMMING
7. QUICK START-UP
Follow these basic steps for activating the controller. If necessary,
consult the indicated reference for each step to get detailed informations.
ADJUSTING COMMON PARAMETERS
1. Connect the control according to the wiring diagram enclosed with
this manual.
2. Turn the power ON.
3. Adjust the clock (see sec. 8.2).
4. Adjust the day counter. This counter is used to activate the light
programs (see sec. 8.3).
5. Adjust the minimum light intensity. This is the lowest level of lighting
used when no programs are currently active (see sec. 8.4).
6. Adjust the sunrise duration. This is the duration of the transition from
minimum to maximum light intensity in a light program (see sec. 8.5).
7. Adjust the sunset duration. This is the duration of the transition from
maximum to minimum light intensity in a program (see sec. 8.6).
8. Adjust the percentage used for activating the auxiliary output. (see.
sec 8.7).
9. Adjust the percentage used for deactivating the auxiliary output (see
sec. 8.8).
10 . Set the period menu to On or Off depending if you are planing to use
periods or not. The controller uses periods to automatically change
the lighting programs based on the animal age (see sec. 8.8).

8.7 AUXILIARY LIGHT OUTPUT
The VLC-3 can be programmed to activate or deactivate a fluorescent
light output at a specified light intensity. Two modes of operation are
possible. In the first case, the fluorescent lights are turned on when the
light intensity increases above a certain level (AUXILIARY ON). When
the light intensity falls below the turnoff level (AUXILIARY OFF), the
fluorescent lights are turned off. In the second case, the fluorescent
lights are activated when the light intensity falls below a certain level
(AUXILIARY ON). When the light intensity increases above the turnoff
level (AUXILIARY OFF), the fluorescent lights are turned off. The two
cases are illustrated in the figures below.

8.8 PERIOD MODE
This parameter allows to activate or deactivate the controller’s operation
in period mode. If the period mode is activated, the controller will
automatically change the dusk-to-dawn programs according to the animal
age. For example, the controller can operate this way:
If the period mode is deactivated, the same dusk-to-dawn program will
operate each day. The animal age will not influence the programming.
Refer to section 9.2 to set a programming using periods.

9. OVERVIEW OF PROGRAMMING SEQUENCES
The VLC-3 is programmed in sequential fashion using the push-button to
advance to the different steps in the program. Two basic program units
are defined: dusk-to-dawn programs and light peaks. Once inside a
program unit, the user must step through all the parameters defined for
the unit before stepping to another unit. This ensures that program
definitions are always complete. However, all program units do not have
to be entered at once. The user can add program units by stepping
through the initial program and adding new units as required. The
diagram below shows how programs are organized. The highest level of
definition in a program is the period number. Each period contains a
number of dusk-to-dawn programs followed by a number of light peaks.
These units are ordered according to the order in which they were
entered. When stepping through an existing program for a given period,
all the dusk-to-dawn programs are presented, followed by all the light
peaks. If you continue stepping through, the following period is presented.
DUSK-TO-DAWN PROGRAM 1
DUSK-TO-DAWN PROGRAM 2
DUSK-TO-DAWN PROGRAM 3
etc.
LIGHT PEAK 1
LIGHT PEAK 2
etc.
Selecting a program unit: When you are at the top of a program level —
for example, period 1, dusk-to-dawn program 1 or light peak 1 — the
adjustment knob (on the right) can be used to select a program unit. For
example, when you enter program mode, before you step through the
first program unit, you can select the period you want to display. The
adjustment knob allows you to go forwards and backwards in the list.
Adding a program unit: To add a new program unit to an existing
program, step to the end of the list for that type of program unit (e.g.
dusk-to-dawn program). The last item displayed is always a blank
program used for adding new program units. Press the step push-button
to step to the state (which is OFF) and change the state to ON. Follow
through the parameter sequence by pressing the push-button and adjusting the parameters using the adjustment knob.
