RTD Ranges (4 and 8CLS)
Pulse Sample Time
You can connect a digital pulse signal of up to 2 KHz to the controller's
pulse input. In this menu, you specify the pulse sample period. (This is
the second menu of the Set up Loop Inputs menu for the pulse input
loop only.) Every sample period, the number of pulses the controller
receives is divided by the sample time. The controller scales this
number and uses it as the pulse loop's process variable.
Selectable Range: 1-20 seconds.
Loop Name
Use this menu to name your loop using two-characters. After specifying
a new name, it is placed on the single loop display instead of the loop’s
number.
Input Units
Use this menu to choose a three-character description of the loop’s
engineering units
