The temperature input is also monitored for under and over temperature by comparing it to
configured set points. The under or over temperature can be transmitted as a digital signal
on any valid configurable SILBUS channel address. A hysteresis level can be configured for
each input to stop the set point alarms from chattering because of noise on the temperature
signal from the sensor.
All configurable aspects of the temperature transmitter can be programmed via the console
port. The transmitter will operate with 8, 16, 32, 64 and 128 channel SILBUS networks and
will automatically configure to the number of channels of the connected SILBUS network.
5 OPERATING INSTRUCTIONS
The single channel temperature transmitter does not require any operator action to operate
once it has been installed within an IP54 host enclosure and configured correctly.
An understanding of the various flash sequences of the yellow status LED may be required
to help in the trouble shooting and maintenance of the entire SILBUS network installation.
The status LED provides information on the operational status of the transmitter and the
connected SILBUS network. This information includes correct microprocessor operation
and health of connected SILBUS network. The table below shows the various flash
sequences and their meaning.

The console port power source selection switch SW1 must always be in the run position for
correct operation of the transmitter. The run position is with the small slide actuator pushed
closest to the black four pin console connector X1.
6 CONFIGURATION
The single channel temperature transmitter has several operational parameters that require
configuration prior to use. All of these parameters can be viewed and changed via the
console port. The console port consists of a small four pin connector and a two position
slide switch behind the front panel label. Access to the console port can be gained by
snapping out the front panel using a wide bladed flat screw driver in one of the slots
between the front panel and terminal blocks.
To use the console port an Austdac MEAN1 interface, A to B USB cable and laptop
computer running Hyper Terminal or any other console program is required.
For more detail on the console port, MEAN1 interface and their use refer to Austdac
document 53-018-11.
