The Drawbar Continuously Moves Back and Forth.
1. Strings may be too tight and drawbar cannot reach HOME. Check string adjustment.
2. If this problem occurs when you start the pinspotter, check the LOS (HOME position)
optical sensor.
The Drawbar Does Not Go All the Way Back to the Home Position.
1. Check the string adjustment, they are probably too tight.
One or More Fallen Pins Are Respotted When They Shouldn’t Be.
1. Check the Pin Detector Count (sensitivity) setting. Change the setting to be more
sensitive (lower number).
2. Check the Pin Data Delay setting. Increasing the delay time will allow pin action to be
completed before fallen pins are recorded. This remedy is indicated if late falling pins
are being respotted.
One or More Pins Remain UP When They Should Be Spotted.
1. Check the brake adjustment for those pins.
2. Check for frayed or tangled string(s) inside the machine.
Machine Cycles Up and Down
1. Check the chassis display for an error message.
2. Strings tangled. Untangle routine in progress.
3. Check pin detector operation. Red LEDs on pin detector circuit board assembly should
go on and off when pins are being raised or lowered. Check for clogged holes (from dust
and string shavings) in the pin detector wheel(s) and optical sensor(s).
4. Faulty pin brake adjustment. Machine sensing pin movement for a pin that should be
held up and is attempting to correct. Will stop after several tries. Adjust brake.
5. Failed solenoid or bad connection. Check connection at solenoid and pin detector board.
6. Pin(s) fall over while being spotted. Check for damaged pin(s) or debris on pin deck.
