## Narrative

The 1085 level hoist was inoperable for approx. 4 hours due to corrosion on the auxilary switch on the scroll latch, which caused it to fail. Because of the faulty switch, the digital hoist supervisor on the PLC dropped the ""WD1"" relay & would not reset properly. Maintenance replaced the switch & reset the PLC. No injury or equipment damage.
