PLC Touch-Screen Controls

Bebco recognizes that our client's needs and preferences are stringent, so we provide the world's most advanced solid-state
electronic controls, featuring a PLC that provides on-board diagnostics and touch-screen controls.

The intuitive touch-screen displays system status and provides adjustment of a time delay setting for all alarm contacts
to prevent nuisance alarms. It also allows adjustment of cooling and heating set points, and displays the status of all
inputs and outputs along with low and high refrigerant pressures to facilitate diagnostics.  Special features include
an optional low ambient protection switch, an optional enclosure pressure switch to disengage optional integrated
heating elements, and a continuous manual fan mode to enhance enclosure convection heater functionality.

Model EAC Units also feature three fail-safe alarm contacts that may be independently programmed
to alert operators to low and high enclosure temperatures and Model EAC Unit performance faults,
along with a self-powered signal loop to permit remote emergency shut-down of the unit.
