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.
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. VLC-3 rev.04...

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.

(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. VLC-3 rev.04...

(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. VLC-3 rev.04...

Press the push-button to store the minutes in memory. 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).

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. VLC-3 rev.04...
VLC-3 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.
When a dusk-to-dawn program is turned off, the user exits the dusk-to-dawn program cycle and enters the light peak cycle. The current state of the dusk-to-dawn program flashes on the display. Use the adjustment knob to set the state of the program. VLC-3 rev.04...
