5.11 Input contacts
The terminal of the SC450G provides for an input contact (see Figure 3.7). This input
contact can be used to switch the range of the outputs. The range can be increased by 1
decade. This is available for only mA1 output.
5.12 Error configuration
l
Errors 1/3 ~ 3/3
Errors are intended to notify the user of any unwanted situations. The user can determine
which situations should be classified as:
FAIL, immediate action is required. The process variable is not reliable.
WARN, the process variable processes by the converter is still reliable at this moment, but
maintenance is required in the near future.
l
Flashing “Fail” flag in main display
“FAIL” gives a flashing “FAIL” flag in the main display. The contact configured as FAIL
(Commissioning >> output setup)
will be energized continuously. All the other
contacts are inhibited. Exception is the contact configured for ‘Wash’. Wash cycles are
not interrupted as this might cause scaling/fouling to the electrodes. A Fail signal is also
transmitted on the mA-outputs when enabled (burn high/low).

l
Flashing “Warn” flag in main display
“WARN” gives a flashing “WARN” flag in the display. The contact configured as FAIL
is pulsed. All the other contacts are still functional, and the converter continues to work
normally. A good example is a time-out warning that the regular maintenance is due. The
user is notified, but it should not be used to shut down the whole measurement.
