TROUBLESHOOTING
Common Problems
MOTOR IS JERKY
Your
Smart Chain Hoist
motor may need to be auto-tuned. Auto-tune from Spikemark and run the
motor again.
Double check all motor and brake terminations in the Harting connectors on installed cable and in
machine whip. A loose or poorly terminated brake lead can cause jerky motion and VFD faults.
There may be an issue with the parameters on the VFD, double check that they are correct and adjust
them according to the table above. Be aware that improperly set parameters can damage your scenery
and/or machine.
LUBRICATION
As with all chain hoists, lubrication is essential to the longevity of the chain. A chain improperly
lubricated is not only loud, but can also be dangerous. The increase in friction will cause the dry chain
to grind and wear itself out.
The frequency in which you lubricate your hoist chain varies depending on the amount and severity of
use. Industrial use of chain hoists usually calls for weekly intervals of lubrication, however it is your
discretion if you need to lubricate your hoist chain more or less frequently.
The type of oil used for lubrication is also important to your chain hoist. There are many different oils
that can be used, however they should all use an ‘EP’ additive. ‘EP’ or ‘Extreme Pressure’ additives
allow your lubrication to stay between your chain links under a full load. CM recommends the use of
10R mineral oil by
Lubriplate
. The Smart Chain Hoists that we send out pre-oiled with Toolmates 7043
oil by
Aervoe
.
(Note: Never use motor oil as a chain lubricant.)
STAGEHAND DISPLAYS DRIVE FAULT
Your E-stop may be engaged. Check to make sure that your E-stop is plugged in and disengaged.
There may be an issue with the parameters on the VFD, double check that they are correct and adjust
them accordingly. Be aware that improperly set parameters can damage your scenery and/or machine.
VFD IS FAULTING
E.EECT - confirm signal cable is connected to the Smart Chain Hoist
E.OSD - most likely a faulty connection in the Motor/Brake cable. Check terminations.
