The de-tangle sequence used by the pinsetter is determined by the Detangle Sequence setting selected
on the options menu. Choose the sequence that is best for the installation. Refer to Figure 3-28.

Default Sequence
During the default de-tangle sequence, the drive motor will shut off to release the string tension and
allow gravity to lower all pins part way towards the pindeck. After one second, the motor turns back
on to raise the pins. If a tangle is still present it will again be detected by the de-tangle switch and the
motor will shut off for another second to lower the pins. After 5 attempts to de-tangle the strings, the
motor shuts off to lower the pins completely to the pindeck. The motor then turns back on to lift the
pins to begin another 5 attempt sequence. The pattern will repeat until the tangle is corrected or the
pattern has repeated 6 times (30 attempts). After 30 failed attempts to correct the problem, the motor
will shut off to allow the pins to lower to the pindeck, the trouble light will flash, and Controller will
show a “Tangle-01” error code. At this point a service person must turn off the machine and manually
correct the problem.
Hold 3 - Odd-Even - Wave
To further increase the chances that the de-tangle procedure will be successful, alternative shake
patterns are used when the Hold 3, Odd-Even, or the Wave sequence is selected. Unlike the default
sequence where all pins are lowered toward the pindeck, these options use the brakes within the PMI’s
to produce a repeating pattern during which only specific pins are allowed to lower.
