Troubleshooting No Power to the Console
This troubleshooting is for P10, P20, or P30 consoles only. P80's use their own power source.
Upper Display does not illuminate
1. Because this is self-powered unit, the display will not illuminate until it is used or the optional
external power supply is equipped. If the optional external power supply is equipped, the display
should be constantly illuminated. If the optional external power supply is not equipped, the unit
must be used at a stride rate of 20 strides per minute or higher for the display to illuminate.
2. If the optional external power supply is not equipped, skip to step 5.
3. Disconnect the optional external power supply from the EFX and measure between the inner
and outer sleeves of the power supply’s output jack with a DC voltmeter. You should measure
approximately 18 VDC.
4. If the voltage measured in step 3 was significantly low, replace the optional external power
supply. If the voltage measured in step 3 was 0 Vdc, disconnect external power supply from its
AC outlet and measure the voltage at the AC outlet. If the AC outlet voltage is normal replace
the optional external power supply. If the AC outlet voltage is significantly low or 0 Vdc, the AC
system must be inspected by an electrician.
5. Troubleshoot the generator per Procedure 9.2.
6. If the generator was found to be good, the problem will be in either the lower PCA, upper PCA or
the upper to lower PCA interconnect cables.
Warning
Because this is a self-powered unit, it will either be necessary to either equip the unit with the optional
external power supply or have an assistant pedal on the unit while voltage measurements are being
taken. Because of the danger of working on the unit while it is in motion using the optional external
power supply is strongly recommended.
7. Remove the rear cover and disconnect the interconnect cable from the J2 connector of the lower
PCA.
8. The following voltage reading must be taken while the unit is in motion. Extreme care must be
taken to keep meter leads, hands, etc. clear of all moving parts. Using a DC voltmeter, measure
the voltage between TP13 (+5D) and TP4 (DGND). Refer to Diagram 5.13.1. The voltage
measured should be approximately 5 Vdc. If the voltage is significantly low, replace the lower
PCA. Additionally, the DS1 LED should illuminate.
