The DG-Mini allows for several programmable
door positions. The connected encoder is
used to determine the door position.
Common door positions are shown in the
example to the right. Additionally, depending
on the encoder type it may be necessary to
have a reference switch input so that the
controller can determine a door’s position
after power up.
Rolling door positions example:
Breakaway
Fully Open
Pre open
Part open 1
Part open 2
Photoeye OFF
Safety edge OFF
Pre closed
