3.5 Set Point Error Codes
Failure of the 943-227-17 preamplifier may result in the following error codes being displayed on the
controlling device:
Code E0009 is normally used to identify a Loop communication failure. The error code may be due to a
baud rate mismatch between the preamplifier and the UDR or 960 system communication board, a failure
on either the preamplifier or UDR communication board. To clear the error code, the source of the error
must be corrected.
3.6 Software Calculations
The 943-227-17 continuously converts the current output of the detector to a digital value, controls the
gain of the internal amplifier, performs periodic self checks, communicates with the UDR or Model 960
controller and provides a radiation value to the UDR of Model 960. An asynchronous, serial
communication interface, processed through optically isolated drivers/receivers is utilized. The digital
value is transmitted to the associated UDR or 960 System controller for further processing. Refer to the
associated controller manual for further information. .
