(for functions 1 to 3 only)
For the ramp function, it is possible to
enter a tolerance band around the set point
value curve to monitor the process value. A
tolerance band signal to be used internally
or transmitted via an output is triggered
when the upper or lower limit is exceeded.
In the following example, the tolerance
band (toLP) is 40K. Thus a tolerance band
signal is triggered when the process value
exceeds the upper or lower set point value
by 20K.
Further information about the use of the
tolerance band signal:
v Chapter 7.6 „Outputs“
v Chapter 7.7 „Binary functions“
TIP!
The ramp function is cancelled in the event of a probe break or in
manual mode. The outputs react in the same manner as for an
overrange/underrange (configurable).
