Troubleshooting 5000 SRM 969
PROBLEM POSSIBLE CAUSE PROCEDURE OR ACTION
One extension b
eam will not
retract.
No electrical p
ower at solenoid valve
mounted on rear
of extension cylin-
der.
Check for prope
r voltage at solenoid.
If voltage is pr
esent, replace solenoid.
If voltage is no
t present, check appro-
priate switch
.
All twist locks will not oper-
ate.
Low hydraulic pressure at attach-
ment main relief valve.
Adjust pressure at main relief valve
to 140 bar (2031 psi).
No electrical power at solenoid
valves on both lift truck and chassis
supply valves.
Check for proper voltage at solenoid.
If voltage is present, replace solenoid.
If voltage is not present, check appro-
priate switch.
Twist locks of one end beam
will not operate.
No electrical power at twist lock so-
lenoid.
Check wiring harness at solenoid or
replace faulty solenoid.
Faulty solenoid. Replace solenoid.
Mechanical obstacle stopping move-
ment of twist lock tie rod.
Remove obstacle.
Sideshift cylinder will not
function.
Low hydraulic pressure at attach-
ment main relief valve.
Replace main relief valve.
No electrical power at solenoid
valves on both lift truck and chassis.
Check for proper voltage at solenoids.
If voltage is present, replace solenoid.
If voltage is not present, check appro-
priate switch.
No power at solenoid on auxiliary
block.
Check for proper voltage at solenoid.
If voltage is present, replace solenoid.
If voltage is not present, check appro-
priate switch.
One or all indicator lights do
not function.
Blown fuse or bulb. Replace blown fuse or bulb.
Proximity sensor switch is not func-
tioning.
No input signal to sensor switch.
When sensor switch is activated, an
LED in sensor is illuminated. Re-
place faulty sensor switch. Adjust
distance between sensor switch and
sensor bracket to proper value.
