Description
The error 11 watchdog monitors the
upper PCA low voltage power. If the low voltage power
drops below a preset level, the
error 11 will be displayed.
Possible
Causes
1. A failure in the upper PCA
overloads the low voltage power supply and causes it to drop
below the preset limit.
2. A fault in the interconnect cable
(lower PCA to upper PCA) causing the input voltage to the
upper PCA to be too low.
Possible
Remedies
1. If the error message is
consistently displayed when the unit is powered up, the upper PCA
should be replaced. It is possible
to see this message displayed intermittently due to external
causes. If the units A.C. input
significantly dips during the power up test sequence the test
could fail resulting in this message
being displayed. Treadmills operating on non-dedicated
A.C. circuits may see this message
displayed on an intermittent basis.
2. Substitute a known good
interconnect cable in place of the existing cable to determine if the
interconnect cable is the cause. For
the purpose of the test, the substitute cable should be
connected
directly between the upper and lower PCA’s.
