Daktronics T-7060 Touchpad - Manual (Page 14)

8 Maintenance & Troubleshooting
4.3 Inspection Procedure
Visually inspect:
 Banana plug for corrosion – if corrosion is found, refer to Section 4.6
 Cable for cuts – if cuts are found, refer to Section 4.6
 All edge protectors are securely in place
 Rubber boot across the top of the touchpad is not ripped/torn and is adhered in place
 Non-slip surface on the face of the touchpad is not cut, torn or peeling
 The touchpad is not delaminating. This will be evident if the face of the touchpad
looks like it is ballooning, with big bubbles (6 + inches in diameter) or when pressed,
it is loose.
 For sharp edges; remove any sharp edges with a file
 Touchpad brackets are adjusted correctly for the gutter type
 Touchpad is flat against the pool wall, with no water inlets or other obstructions
between the touchpad and the wall
4.4 Advanced Touchpad Troubleshooting
1. Plug the touchpad into the touchpad input on the lane module or deck plate. Make sure
that the GND tab on the touchpad connector is lined up with the black jack on the lane
module/deck plate touchpad input.
2. Make sure that the lane modules/deck plates are connected to the OmniSport 2000
console and that the console is powered on and in swimming mode.
3. Using a DC voltmeter, connect the red probe to the positive connector of the touchpad,
and connect the black probe to the GND connector of the touchpad.
 With the touchpad installed and not being pressed, 0.25 V DC should be measured.
 When the touchpad is pressed, the voltage should drop to approximately 0 V DC.
 When the press is released, the voltage should start climbing for approximately 1.5 -
3 seconds and level out at 0.25 V DC again.
If the readings are different from those described above, use the following table to
determine the possible cause and solution. If a problem occurs that is not listed or that
cannot be resolved, contact Daktronics using the information provided in Section 5.
Problem Possible Cause Solution/Items to Check
Voltage measured on the
banana plug of the touchpad
cable when it is plugged into
the lane module or deck
plate is 0 V DC or close to it
Bad connection between the
banana plug and the lane
module (on-deck) or
deck plate (in-deck)
1) Clean both the male banana
plug on the touchpad cable and
the female jack on the lane
module or deck plate.
2) Using a small straight screw
driver, bow out the center of
each of the 4 leafs on the male
banana pin so that it provides
more pressure on the contact
when the banana plug is
inserted into the lane module or
deck plate (see Figure 11).
3) If cleaning the connections
doesn’t resolve the problem,
check the next Possible Cause.
