Troubleshooting guide
Problem
Solution
LCD displays ‘timeout’, nothing works.
PCU9669 socket might be loose. Assure good contact
on PCU9669, then press ‘CPU_RESET’ again. This
usually corrects the time-out issue and you can press F1
or F2 to start your routine.
Stepper motor boards will not start.
Press ‘CPU_RESET’ several times, then ‘F1’.
One or more motor board spinners
are not ‘in sync’ with other spinners.
Press ‘CPU_RESET’ and restart with ‘F1’.
Spinner not turning, strange sound
coming from motor board.
Spinner has been moved and is making contact with
optical switch. Move spinner by hand (soft metal), fix
bend or placement error until you can rotate by hand
through both sensors without touching.
Press ‘CPU_RESET’ and ‘F1’.
One or more spinners seem to have
incorrect timing, possibly one left motor
moving when right board is enabled
(as an example).
Address pins are incorrect. Verify address pin locations,
and restart demo.
Acting strange, not everything working.
Verify all eight red LEDs on the control board are lit up. If
not, possible power supply loss. Can be caused by
shorting connections on smaller boards or during ‘hot’
cable changes.
Parts damage seen on motor boards.
14-pin LED cable (which is wired reverse from standard
cable) has been plugged into motor boards. PCA9629’s
will be blown and need to be replaced as well as any
capacitors, inductors or ESD protection diodes before
boards will work correctly. Puts +24 V on +5 V line.
