AccuScore PLUS
NO RUN
1. Check fuses
2. Check power supply. Output should read +5V, if there is less than +4.85V output, replace power supply.
3. Swap EPROM module with a known good unit.
4. Call us for assistance.
NO COMMUNICATIONS
1. Check cables in J2, J3, J4. Make sure that they are a TIGHT fit.
2. There may be another curtain wall chassis that is "tying" up the communications line. To isolate each curtain wall chassis, find the BEGINNING of the communications line and plug the TERMINATOR in J4. Check for communications. If OK, repeat this step by going down the line one chassis at a time. Leave the first curtain wall connected and move down the line 1 curtain wall at a time with the terminator until communications fails. When it does fail, the curtain wall chassis that was LAST to be added to the line is faulty.
3. Reboot the front desk computer.
4. Call us for assistance.
NO SWEEP REVERSE ON ONE OR BOTH LANES
1. Check for proper scoring on the screen w/o sweep reverse. If the score is incorrect, the pinsensing system is at fault. Check pensensing unit.
2. If the lane is controlled by a MP chassis, replace the MP board with a known good unit.
3. Replace the chassis with a known good unit.
4. Call us for assistance.
KEYBOARD INTERMITTENT OR DEAD.
1. Replace keypad with a known good unit.
2. Replace bowler terminal P.C. board with known good unit.
3. Check for any hardware that MAY have "fallen" on the bowler terminal board (ie: speaker mounting screws)
4. Replace the C.W.C.
5. Call us for assistance.
ACCUSCORE 1 & 2
Keyboard dead or some letters or numbers don't work
1. Check connection to the curtain wall chassis.
2. Replace keypad.
3. Replace bowler terminal PC board.
4. Call us for assistance.
ONE OR BOTH LANES MIS-SCORING.
1. Replace the Accusonic MPU board with a known good unit.
2. Check power supply for blown fuses (+40 V supply).
3. Check alignment of accusonic array assy.
4. Replace the accusonic array for lane which is mis-scoring.
5. Make sure cables are seated properly.
6. Replace the expander P.C. board with a known good unit.
7. Call us for assistance
NO COMMUNICATION (1 PAIR)
1. Check to see that the communication cable is secure at the front desk & at the CWC's.
2. Reboot the front desk.
3. Bypass the pair that is not communicating (with a jumper cable).
4. Replace the EXPANSION board.
5. Replace the EMC board.
6. Replace the MPU board.
7. Call us for assistance
NO COMMUNICATIONS (MORE THAN 1 PAIR)
1. Check the communication cable from the front desk to the CWC's.
2. Reboot the front desk.
3. Eliminate ONE pair at a time with a jumper cable.
4.Call us for assistance.
Note: AMF suggests that you should shut down the entire system (Accu+) once a week overnight. That includes the curtain wall chassis' as well as the front desk. They say that this can possibly eliminate "problems" from accumulating.
Please note: Communication problems can be difficult to troubleshoot since all the lanes are tied together in a "Daisy chain". This means one scorer can "tie" up as few as 1 pair & as many as ALL of the scorers. The BEST way to eliminate one pair from the "Daisy chain" is to use a "jumper cable" to by-pass one pair at a time. If you don't have one of these cables, we can supply one.
PLEASE NOTE IF YOU HAVE WELLS-GARDNER MONITORS!

Sometimes the H.V. transformers on Wells-Gardner monitors can develop a small crack in them! If this happens you can see a small blue "arc" from the transformer body to the frame surrounding the transformer. THIS CAN MAKE A C.W.C. FAIL! If you have such a monitor, do this:
1) Turn off power to the monitor.
2) At the place of the "crack", apply a liberal amount of silicone sealant.
3) ALLOW THE SEALANT TO DRY OVERNIGHT!! (If it isn't fully cured, it will conduct!)
4) After you are SURE the sealant has cured properly, re-apply power to the monitor.

THIS IS A "CHEAP" FIX! The H.V. transformers on these monitors tend to have this problem after a few years of use.

IT MIGHT BE WORTH YOUR WHILE TO REMOVE THE BACK COVERS OFF OF ALL OF YOUR MONITORS A COUPLE OF TIMES A YEAR & VIEW THIS AREA IN THE DARK TO SEE IF THERE ARE ANY POTENTIALLY BAD TRANSFORMERS. IN THE DARK YOU CAN EASILY SEE THE "ARC".

PLEASE CALL OR EMAIL IF YOU HAVE ANY QUESTIONS ABOUT THIS PROBLEM!!
PLEASE NOTE!
THE HIGH VOLTAGE PRESENT IN MONITORS CAN EXCEED 35,000 VOLTS! BE VERY CAREFUL AROUND THE TRANSFORMER!!!!
More coming soon...
