This value is usually set to be slightly greater than the fastest process response
expected during a 1 second period, but measured for at least 2 seconds.
If the
process is faster than this setting, the SEnC bAd error message will appear. The
outputs will then be turned off.
This function can be used to detect a runaw ay
condition, or speed up detection of an open thermocouple. Use the INDEX INDEX INDEX INDEX INDEX &

When a current or voltage output is used, the standard output value is 0 to 20mA
or 0 to 10V. If 4 to 20 mA or 2 to 10 V is required, the S#OL value should be set for
20% to raise the low est output.
