Physical Description

Operation
Should a hazardous condition arise, the DCA can
be arranged to operate an alarm, initiate a
shutdown or cut in a cooling fan at a pre-determined
operating temperature, preventing damage to your
valuable plant machinery.

The DCA consists of a single compact non-adjustable
unit based on a 32 A/F hex zinc plated and passivated

Installation Considerations

steel body. This enables the control to be fitted directly
into the application.
The DCA provides fast, accurate temperature response
through a brass phial that protrudes into the application.
Electrical connections are configured by attaching
standard 6.35 mm Faston terminals. Upon installation,
normally open/closed or change over may be selected.
Special variants with an internal earth (earth return) and
an improved IP68 rating can be specified upon order. A
rubber Gator is also available as an optional extra.

Check there is enough clearance around the flats
of the body and that the phial extends to the
application by 31mm from the base of the Hexagon
(see outline details).
The DCA automatically resets once the application
has cooled; the differential varies according to the
temperature set point (nominal 9°C).
