Contactor Control Systems 1. Purpose Contactor Control Systems allow an electronic temperature controller to stage in equipment in predetermined increments. The contactor panel is intended for use in agricultural enclosures. 2. Ratings/Specifications • • • 3. 120 or 240 volts / 6 Amps Maximum / 50/60 hertz (depending on model purchased). 2 hp maximum per stage. 4, 8, or 12 stage models available.
. Limited Warranty All products are warranted to be free from defects in material and workmanship for a period of one year from the date of purchase if installed and used in strict accordance with the installation instructions. Liability is limited to the sale price of any products proved to be defective or, at manufacturers option, to the replacement of such products upon their return.
9. Connect wires from staged equipment to the appropriate stage. Be sure to align the heat/cool switches to the appropriate settings. See wiring diagrams for locations of terminals. Back-Up System ! ! M a n u a l Stage Controls The CCS-8 Contactor Control Panel. 6. Components Description 6.1. Contactor Panel 6.1.1. General Description Hired Hand’s Contactor Control System is a pre-wired set of heavy contactors designed to allow automatic switching of large loads. (Up to 2 Hp per stage.) 6.1.2.
These switches must be in the proper position.

Front Panel The only controls on the outside of a standard contactor panel are the “Auto/Off/On” toggle switches.
6.2.2.1. High Limit If for some reason (lightning, voltage fluctuations, etc.) your controller should quit functioning, or function improperly, the back-up system in your CCS panel will turn stages on or off if temperature exceeds the high or low limits. If the temperature felt by the sensor reaches one degree above the high limit, the backup board would start all stages set to cool one. (This could be any, or all of your cool stages.

STAGE When the back-up board calls for Cool 2 the remaining cool stages would start.
6.3. House Lighting Option 6.3.1. General Description On contactor panels ordered with the light control option, the panel has a double pole contactor installed inside the panel at the top of the unit. To the left of the lighting contactor is a four-position terminal strip. You can break up to two circuits with this contactor. 6.3.2.
8. Maintenance There are few items on the CCS panel which require maintenance. This does not mean that maintenance is unimportant. Remember that the more time you spend making things right, the less time you will spend correcting problems. To prevent malfunctions of the contactor panel, keep your panel clean and free of debris. Follow all safety warnings when working with electrical equipment.
