Dear Mr. Yuthana,
Regarding the trouble burned transformers with hoist YSL-050 [22-2016001483 and 22-2016001486], after engineers’ study with yoru pictures, the insulation of motor coil has been demaged completely, it should be caused by over-laod and over-used.
We can not have answer about the trouble of transformer burned, suggesting to return us the demaged items : burned motor coils and transformers for engineers’ inspection.
Returned demaged motor coils + transformers could be combined with the pendant control together.
Please collect the pendant control which needs to be replaced with PBS+E/S and arrange return shipment asap.
