The
Level Follower has a number of manual control options. Find Upper Limit sends
the level follow to the top of its range. Up Slow sends the level follower up slowly.
Track mode instructs the level follower to find the current liquid volume in the receiver
and follow it if it increases. Down Slow sends the level follower down slowly. Find
Base sends the level follower down till the base is found. Standby cancels previous
commands and leaves the level follower in the rest position.
There are also a variety of outputs from the level follower.
Counts tells how many steps
the level follower is from the base. Sensor indicates if the level follower eye is blocked
(liquid is blocking the light from the emitter to the detector). Clear indicates liquid is not
blocking the light from the emitter to the detector. Volume tells the volume of liquid that
corresponds to the current level follower position. Lower Limit indicates if the lower
limit detector is blocked (on) or not blocked (off).
