that needs its timeout value to be changed. To select a different channel or parameter,
enter the submenu. The display will show the channel on the left and the parameter on
the right. The lower button increases the channel (1 to 128), the raise button increases
the parameter (1 to 8). Once the channel and parameter have been chosen, exit the sub-
menu.
Burnout Level Control
When an output is following an input (because it is linked to it via the LINK and OUT
menu) at some stage it may need to indicate the value it is following is not valid. This
occurs if the input has an error condition (burnout, data not available, etc) or has timed
out because data has not refreshed recently enough (see Burnout Time Control in the
next section).
The Burnout Level menu allows individual outputs to indicate this condition by either
going to a HI burnout value (23 mA or 11.5 V for analog output, On for a digital output), or
a LO burnout value (0 mA or 0 V for analog output, Off for a digital output).
To change the burnout level of an output first select the correct channel and parameter
using menu 10. BURNOUT. Then select menu 11. LEVEL and in the submenu choose HI
or LO.
The default Burnout Level for all parameters of all channels is HI.
Burnout Time Control
Each channel has an Age parameter associated with it to indicate how old the data is. If
the device providing that data becomes unable to send any new data, there comes a time
when the data held by the IWR-Port can be considered too old to be valid. It is possible to
set a time limit on each channel that will make the IWR-Port change old data values to a
timeout error condition (0xFFFE or E 15 on the display) if the time limit is reached.
To change the timeout value for an input channel first select the correct channel using
menu 10. BURNOUT. Then select menu 12. TIME and in the submenu choose OFF to
disable the timeout, or a value between 1 and 255 inclusive.
The default Burnout Timeout for all channels is OFF.
View Burnout (13. VIEW BURNOUT)
To view the burnout configuration for each channel uses the 13. VIEW BURNOUT menu.
The channel burnout time and parameter burnout levels can be seen in a scrolling
message.
e.g. for channel 2:
C2 30 P1 HI P2 HI P3 HI P4 HI P5 HI P6 HI P7 HI P8 HI
This shows that if this is an input, its data will become invalid if it is older than 30 seconds
(or minutes depending on the AGE parameter selected, see section 6.15).
e.g. for channel 3:
