Output Configurations
The sensors/controllers are supplied from the factory (unless otherwise ordered) with
0...10VDC linear outputs for Out(1) and Out(2) (see Table I). If other options are
needed for the application, the output jumpers have to be configured before the unit
is powered up. Each jumper selection is independent from the others, except for the
"Start point selection" jumper, which affects both, Out(1) & Out(2), linear outputs.
Alternative measuring ranges of the outputs can be selected with the software UIP
(version 5.0 or later).

Self-diagnostics
The system contains complete self-diagnostic procedures. A full system test is
executed automatically every time the power is turned on. In addition, constantly
during operation, the sensor probes are checked against failure by checking the valid
dynamic measurement ranges. All EEPROM updates, initiated by the sensor itself,
as well as by external connections, are checked by subsequent memory read back
and data comparisons. These different system checks return error bytes to the
system RAM. The error codes are available by connecting a PC with a special
RS232 cable connected to the UART port slide connector. The error codes are
shown in the software UIP (version 5.0 or later). Warm up and Out of Range are the
only bits that are reset automatically after return to normal state. All other error bits
have to be reset manually after return to normal by power off/on.
Jumper top position provides 0Vdc or 0mA start point for Out(1), Out(2)
(0-20mA or 0-10V).
Jumper bottom position provides 2Vdc or 4mA start point for Out(1), Out(2)
(4-20mA or 2-10V).
Connection in position Current provides 0/4-20mA output range for Out(1).
Connection in position Voltage provides 0/2-10VDC output range for Out(1).
Connection in position Current provides 0/4-20mA output range for Out(2).
Connection in position Voltage provides 0/2-10VDC output range for Out(2).
