The heated optics can be set to one of the following:
•
Not operated
•
On continuously
•
Automatic, per temperature change (default): you can define the start temperature
below which the window is heated. (The default is 68°F (20°C).) This temperature can
be defined between 32°F (0°C) to 122°F (50°C). The heating stops when the
temperature is 27°F (15°C) above the start temperature.

1.4.3
HART Protocol
The 40/40 Flame Detectors use the HART Protocol.
HART Communication is a bi-directional industrial field communication protocol used to
communicate between intelligent field instruments and host systems. HART is the global
standard for smart process instrumentation and the majority of smart field devices
installed in plants worldwide are HART-enabled.
HART technology is easy to use and very reliable.
Through the HART connection, you are able to perform:
•
Detector set-up
•
Detector troubleshooting
•
Detector health and status
For more details, refer to the
HART Manual TM 777030
.
1.4.4
RS-485 Modbus
For more advanced communications, the 40/40 detector has an RS 485 Modbus-
compatible output that provides data communication from a network (up to 247 detectors)
to a host computer or universal controller for central monitoring. This feature allows for
reduced installation costs, easy maintenance and local or remote diagnostic tools.
