Installation
Note: Always turn off the power supply to the Digital Controller before changing any switch settings.
■ Settings
On a standard model, set up the Output Units for control outputs 1
and 2 before mounting the Controller.
On a position-proportional model, the Relay Output Unit is already
set. Therefore, this setup operation is unnecessary. (Do not replace
with other Output Units.)
When setting up the Output Units, draw out the internal mechanism
from the housing and insert the Output Units into the sockets for control outputs 1 and 2.
Setting Up the Option Unit
