1. Check that the LED in the charging station
ashes blue, which indicates a break in the
boundary loop. For further information about the
charging station’s LED, see 6.4 Troubleshooting
the loop signal on page 90.
2. Check that the boundary wire connections to the
charging station are properly connected and not
damaged.
Disconnect all connections from the charging
station and then measure the resistance in the
boundary loop. A value over 20 Ohm indicates
that there is a break. If the measured value
is less than 20 Ohm and the LED still ashes
blues, the fault is in the charging station’s
cabling or the circuit board. See 5.20 Replacing
the main circuit board, charging station on
page 76.
3. Connect the charging station to the power
supply. Switch the connections between the
guide wire and the boundary wire in the charging
station.
a) Switch connections AL and Guide. Check if
the LED is ashing yellow.
b) Put AL and Guide back in their original
positions. Then switch AR and Guide. Check if
the LED is ashing yellow.
If the LED is ashing yellow (i.e. the boundary
loop is intact but the guide wire is not connected)
in test a) then the break is somewhere in the
boundary wire between AL and the position
where the guide wire is connected to the
boundary wire (thick black line in illustration A).
