CN63100 OEM Paint Sprayer Application

An OEM manufacturing spray painting equipment utilizes the CN63100 to
maintain optimum paint temperature. In addition to the low cost, the 1/16 DIN
package size permits the OEM to design temperature control into various
sized painting equipment, from small hand sprayers to large paint booths. The
heating element used to heat the paint, is connected to the Main Control
Output (OP1) programmed for On/Off control. Alarm 1 is programmed as
Band Inside Acting, so that as long as the paint temperature is within
manufacturer's specifications for temperature, the "GO" light is on. Alarm 2
is programmed as Band Outside acting so that the "NO GO" light is lit when
the paint temperature is more than 12°outside the manufacturer's
specifications of 140 to 150°F.
