Iceball FX has an optical sensor to monitor the movement of ball release solenoid lever. When the solenoid is blocked on power up the game will generate an error 12, during game if the main board engages the solenoid and does not see the lever move down it will release the coil to prevent damage.
Solenoid seat sensors
When the ball release arm is in its down position rests on a gum rubber bumper if the bumper has become worn or damaged it can cause the arm to travel below the level of the optic causing the game to not see the sensor input blocked. If the solenoid is mounted too far forward on the ball rail assembly the release arm will have the potential to travel below the optics. To rectify this loosen the mounting nuts for the solenoid and slide the coil towards the center of the rail so the arm blocks the optics.
The solenoid seat optics have a red indicator LED on the controller board located on the bottom side of the ball rail. Normal operation is for the led is as follows:
-during game mode the red indicator LED should remain off until the sensor is blocked by the arm.
-When the optics are blocked or misaligned the indicator LED will be on.
-when the game is in error mode (or booting up) the red indicator LED will momentarily flash when the game is sending the enable signal.
The sensor can be checked using a voltmeter set to DC voltage:
pin 1- enable line - grey/violet wire - when referenced to orange wire will be 12v when the game is in game mode and going from~0v to 12vdc during the boot process .
pin 2 - power in - yellow wire - when referenced to the Black/red wire (ground) it should always be 12v
pin 3- signal out - White wire- when referenced to the Black/red wire (ground) you will see 5vdc when the optics are aligned and 0vdc when the optics are blocked.
pin 4 - ground - Black/red wire - this line is digital ground when referenced to the yellow wire it should read 12vdc
