Digital Position-Proportional Controllers
E5EZ-PRR
Operation
In the past, sensor input types, alarm types, and control time for controllers were set using the DIP switch. Now, these hardware settings can
be performed with the parameters in the setting level. The
and
M
keys are used to switch between setting levels, with the level determined
by the amount of time the key is pressed. Two examples of typical setup procedures follow.
