Trouble Shooting
Problem Solution
Poor Distillation Rate Control
Drip trough not in place or not turned so it faces
forward.
Distillation Rate kP too high
Distillation vapor temperature appears too high
Vapor temperature probe holder nut not tightened
enough. Temperature probe is getting “sucked”
down.
Vapor temperature probe position is set properly but
then moved down by itself.
Vapor temperature probe holder nut not tightened
enough. Temperature probe is getting “sucked”
down.
Level follower moves up and appears “blocked”
with a clean receiver in place.
Receiver is not pushed in all the way back into the
black plastic base.
Level Follower Eye does not move
Check operation in manual controls
Make sure lights on stepper motor board are ON
(indicates power to board is on)
Turn level follower screw to move eye by hand
Heating mantle does not heat
Check in manual controls
Check to see that light on heating mantle relay
comes on
Level follower goes up when a run is started.
Lower limit switch is unplugged, blocked or
defective.
Distillation rate too high early in the distillation.
Lower the Intial Heat Rate and intial take off rate
.
Distillation rate too low early in the distillation.
Raise the Intial Heat Rate and intial take off rate
.
Distillation rate too high during the distillation.
Lower the Distillation PID Bias.
Distillation rate too low during the distillation.
Raise the Distillation PID Bias.
