If the Auto-Addressing function does not find all of the required conditions
met, one of the following displays (Fig 8-15, 8-16, 8-17 or 8-18) will be
shown to indicate the cause.
No device in Device Fail
No unaddressed device present
Fig 8-15 – Device Programming Menu – No Devices in Device Fail
There must be one (and only one) device in device fail on that MX loop
for the re-addressing function to be used.
More than 1 device in Device Fail
1 unaddressed device present
Fig 8-16 – Device Programming Menu – Multiple Devices
The OneAtTme function can be used only when there is a single device
in Device Fail.
Device x.x in Device Fail
No unaddressed device present
Fig 8-17 – No Unaddressed Device Present
Ensure that the new device has been correctly fitted to its base, or wired
into the loop, that it has not already been programmed, and that no other
device programmed to address 255 is installed on the loop.
Device x.x in Device Fail
Mismatched unaddressed device
Fig 8-18 – Device Mismatch
Check that the replacement device is of the same type as the removed
one. The OneAtTme function can program only replacement devices
that are of the same type as the device they are to replace.
