The safety module provides the functionality and monitoring of the two-hand control
and the interfacing circuitry.
By placing the two-hand control at a safe distance from the machine, the operatorís hands are not in the hazardous area
when machine operation begins.
The two-hand control system occupies both the operatorís hands with machine start actuator buttons or hand controls. A two-hand control only protects the hands of the operator and is not an effective safeguard
for others in the vicinity of the machine.
A two-hand control should not be easily defeated by motivated individuals. The use of only one hand or the use of simple aids (e.g. U-shaped metal bars) must be considered during machine design and installation.
