4000 °F, °C, or counts per 1 second period.

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.

Set Point 1 output will be directed to terminals 7 & 8 and Set Point 2 output
to terminals 9 & 10.

Outb

Set Point 1 output will be directed to terminals 9 & 10 and Set Point 2 output
to terminals 7 & 8.

Direct Action. As the input increases the output will increase. Most com-
monly used in cooling processes.

Reverse Action. As the input increases the output will decrease.

Most

commonly used in heating processes.

This item limits the

ow est output value.

This is useful for adding a bias to the process when needed.

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.
