WORKING INSTRUCTIONS ON SAFETY STRUCTURAL ELEMENTS

Overspeed governors belong to the safety structural elements group. It is absolutely necessary to observe the
rules and regulations that refer to this structural element, including the information given in the operating
instructions.
For that reason, before beginning to work on this component part, the following operating must be
red and understood, in particular with regard to the chapter concerning "safety precautions".
Safety devices need particular attention. Their perfect functioning is essential for a safe operation of the plant.
The regulation of the safety devices, that can be set only after the assembly, must be carried out immediately

If safety devices are already preset at the factory, their operations have to be immediately tested.
Should it be necessary to disassemble the safety devices during maintenance or repair, when terminated they
have to be immediately reassembled and adequately tested.
In these instructions, the following safety devices are described:
• safety switch on the overspeed governor (adjusted in the factory)
• safety switch on the tension weight with counterweight.
