1-4
Read and follow the safety instructions given in this section before starting any work. However,
local statutory regulations, if stricter, are to take precedence.
The tension measurement system contains no moving parts. However, the load cells are
mounted close to a rotating roll over which a web is running.
Never work with the load cells, or nearby, when the production line is in service.
Before starting any work, switch off and lock the operating switch of the drive
section for the measuring roll.
Switch off and lock the mains operating switch to the tension electronics before
performing any work on the tension electronics. When the work is completed,
check that there are no loose wires, and that all units are properly secured.
All personnel working with the installation must know the location of the main
power supply switch to the measurement system and how it is operated.
Always switch off the mains supply voltage to the measurement system before
replacing a unit.
Handle the electronic unit carefully to reduce the risk of damage from
Electric Static Discharge (ESD). Note the warning label on the circuit boards.
