6. Initial Setup of Variable Output Control Board
(PCB 174 rev C or later)
The following sub-sections describe the usage and settings of each connection, jumper, and switch included on the EV-VAR PCB
#174 revision C or later. The board layout with wiring/setting location references are shown in Section 6.1. The latest PCB174
revision C or later include the following product enhancements:
•
Sunset light control functionality is now provided along with the Sunrise feature which was available on the previous
version EV Variable Output controls. The Sunrise and Sunset features can now be used with less sophisticated systems.
•
The Evolution Variable Output controller is now capable of accepting a 0-10 Vdc input signal from alternative control
systems and use that voltage to dim the lights or vary the fans. This function was previously achieved only with Hired-
Hand Environmental Control Systems.
The Evolution Variable Output models can be used in conjunction with several different control devices such as the Evolution
3000/3001 Control Systems, Farm Hand Control Systems (Stage Master, etc.), alternative manufacturers, 24 hour Time Clocks as a
stand-alone unit, or to any dry contact control output for variable operation of lights or fans. Use the PCB 174 Board Layout and
Setting Locations along with the table listed in Section 6.1 as a quick reference to help direct the specific application to the
appropriate switch settings and wiring diagrams on the following pages.
