Notes
＜To Maintenance manager＞
・ Inspections item at the time of the pre-use test run(Checking at periodic inspection).
・ For using safely, please inspect the system one month after starting regular
operation.
・ The inspection cycle is mentioned below. However, determine your own
inspection cycle based on the actual operating rate and environmental condition.
・ Items in bold: Inspection items requiring particular attention.
A title
Name
Contents of inspection
Check to see if there is any foreign particles
adhering on its sliding surface or if it is seriously contaminated?
Is there any ark generated protrusion on its
sliding surface?
Is there damage and crack at the insulating
sheath ?
Is there sharpen at the insulating sheath ?
Is the duct installed in parallel for a rail?
Isn't the unit dislocated from the hanger?
Are not there remarkable torsion and the curve of the duct? Please revise turning remarkable torsion.
Amount of wear of the conductor is correct?
Amount of wear of the conductor o：0.5 mm or less
Don't the insulated sheath and the resin part
of collector spinning shaft touch?
︵
Are not there the cracks and damaged on a
resin part?
Do stop it i in an insulating tape?
︶
Are not there the cracks and damaged on a
︵
resin part?
Is't there the slack of the lock bolt?
Is not there the torsion?
︶
Is not there the exposure of the conductor?
Is the coil spring set definitely?
Length of the coil spring L =115-125mm
Does not a nut (a double nut) of the coil spring
part have the slack?
Does not a bolt for electric wire connection of
the feeding-in terminal part have the slack?
Are not there the cracks and damaged on a resin part? When damage and crack occurred in it, please change it. ○
Are not there a loser of the cover part, the falling off?
Is not there the exposure of the conductor?
Is not there the torsion?
Are not there the cracks and damaged on a
resin part?
Are not there a loser of the cover part, the falling off? Please install the cover.
Isn't there the conductor of the joint have a gap and the step? Please revise a gap, the step.
Isn't there the slack of the connection bolt?
Are not there the cracks and damaged on a
resin part?
Are not there a loser of the cover part, the falling off? Please install the cover.
Check day
Clean with a specific purpose cleaner or waste
cloth.
Remove any protrusion (convex) on the arc
scratch using a file.
When damage and crack occurred in the insulating
sheath of the duct, please change the duct.
When thickness of the insulating sheath is equal
to or less than 1.2mm, please change the duct.
Please adjust the duct so that it is parallel at a rail. ○
Review for any dislocated position on the unit.
Correct if any.
If it exceeds a threshold amount of wear, please replace the main conductor
In case of wearing down to the replacement indication line at next inspection,
please replace earlier than usual.
Check the amount of wear of the collector and
conductor of the duct,replace it if necessary.
When damage and crack occurred in the fixed
end insulator, please change it.
Please install an insulating tape.
When damage and crack occurred in the fixed
end insulator, please change it.
Retighten
Please revise torsion.
Please install a repair cover for sheaths
Please adjust it to reasonable length
When tighten the duct, Please tighten a nut of
the tightening bolt with balancing in turn.
Ｌ
Ambient temperature
the case of less than 10℃ 115mm
the case of 11℃〜 40℃
Retighten
Retighten
When loser and the falling off occurred, confirm
the state of the cover, and please install the cover. ○
Please install a repair cover for sheaths
Please revise torsion.
When damage and crack occurred in it, please
change it.
