Troubleshooting

Troubleshooting should be issued by competent personnel. Get in touch with EdmoLift if assistance is desired or if an error can not be remedied. All work under the platform, put the service support lock into position. After major repairs you must have a full load and functional test. For instructions contact EdmoLift.

When grinding or welding on the steel structure, harmful substances can be used. Appropriate protective and working methods must be used.

Troubleshooting for lift tables, armlifts, pallet lifters and tilts

Fault
Reason
Action
The motor does not start.
The isolator switch is in OFF -position.

No mains feed.

The E-STOP button is activated.

Primary or secondary line circuit breakers activated.
Turn the switch to ON.

Check the mains supply.

Turn the button clockwise to release.

Check the reason and reset.

No lifting movement.
Motor is rotating in the wrong direction.


Incorrect electrical connection.

The relief valve opens.

Lift Table overloaded, remove the excess load.
Change two phases.(NOTE!Ensure the isolator switch is OFF before the work is started)

Check the connections.

Lift Table overloaded -remove the excess load.

Lift Table overloaded -remove the excess load. Motor protection relay not correctly set -adjust.

Lift table does not reach the top position.
Insufficient volume of oil.



The relief valve opens.
Add oil,but not more than required to reach the top level.Too much oil may cause an overfull oil tank when the lift lowers.

The lift is overloaded -remove the excess load.

Jerky lifting or lowering motion
Air in the hydraulic system.
Check the oil level.Operate the table a few times at approximately 5 minute intervals. When table is at lowest level press the DOWN-button continuously for approximately 1/2 a minute.

The lift table does not lower.
Incorrect electrical wiring.

E-STOP button has been actuated.

The safety frame has been activated.



Primary or secondary line fuses actuated.

The lowering valve does not open.
Check the connections.

Turn the button clockwise to release.

Remove any trapped obstacle.Press the UP-button briefly to reset,then the lowering button again

Check reason and reset.

Check the electric circuit.Possibly the valve cartridge or solenoid coil need to be replaced.

The lift table lowers without DOWN-button being pressed.
Dirt in the hydraulic system









The oil volume decreases due to oil cooling.
1.Operate the lift a few cycles to remove any contaminants from the valve seating.

2.Dismantle the lowering valve,check valve cartridges and clean these.

3.Replace the lowering and check valve cartridges and change to new oil.


Quite normal. If it is an inconvenience, contact EdmoLift for proposal to solve this.

Lifting or lowering speeds faster or slower than desired.
Flow control valve not correctly set.
Adjust the flow control valve NOTE! High speed means increased risk for instable goods.

Check that the lowering rod /wire has not been damaged or if it needs adjustment.

Contact EdmoLift.

The platform does not reach the top level.
Insufficient oil volume.



The relief valve opens.
