SERVICING THE SOFTBALL TIMER

While your softball timer was designed for years of trouble-free operation, some problems may occasionally occur. Electro-Mech Scoreboard Company offers onsite service in some areas. In other areas, we can help you contact an independent service technician. In areas in which service is not available from Electro-Mech Scoreboard Company, we will make every effort to answer your questions. Our trained personnel at Electro-Mech Scoreboard Company are ready to answer your questions from Monday to Friday during the hours of 8 AM to 5 PM Eastern Standard Time. Be sure to know your softball timer model number when calling. Softball timer replacement parts are always available. Damaged parts can usually be repaired at a significant cost savings. Our convenient toll free number is listed at the bottom of every page in this manual.
If the softball timer turns on LEDs, but does not operate normally, make note of which functions are affected. If some LEDs either never turn on or always stay on, make note of their specific locations on the softball timer. Refer to the COMPONENT REPLACEMENT section of this manual before changing parts.

COMPONENT REPLACEMENT

LED digits are serviced from the front of the softball timer.
LED Digits Replacement
The LEDs that form digits and indicators are soldered on circuit boards mounted behind the scoreboard face. Do not attempt to replace individual LEDs. In case of a malfunction, the entire LED circuit board must be removed. To avoid damage to the LED driver module, always turn off the power to the softball timer when removing or replacing LED digits. Figure 12 shows the components of a LED digit assembly. LED indicator assemblies are similar in construction.

  1. The ribbon cable that connects to the rear of the circuit board is not designed to support the weight of the assembly.
  2. Damage to the ribbon cable may create short circuit paths that will damage the LED driver module.
  3. Place the assembly on a flat surface and remove the 6-32 kep lock nuts that hold the circuit board in place.
  4. Remove the circuit board.
  5. Align the mounting holes in the circuit board with the threaded studs on the face panel and install the replacement digit on the face panel.
  6. Refer to figure 13 in order to plug the ribbon cable IDC connector onto the circuit board in the proper orientation.
