In Case Of Difficulty; Specifications - DART Controls 125D Serie Manual Del Usuario

PROBLEM
Motor doesn't operate
Armature output voltage
cannot be adjusted, output
is a constant DC level
Motor stalls, or runs
very slowly with speed
control turned fully CW
Motor hunts
Repeated fuse blowing
If control still will not operate, consult your Dart Distributor or Representative.

CORRECTIVE ACTION(S)
Replace Fuse
Install proper service
Adjust Speedpot CW to start
Replace brushes
Check that motor or load is connected
to armature terminals
Check that speedpot low wire is connected
Check-should be above 100V or 208 V
Reduce load
Replace brushes
