SAFETY EVALUATION
Before releasing an installation for production, test the safety system on a daily basis or whenever a
change or modification to the operation is made. Record and verify all tests and examinations.
Check that the floor and environmental conditions are suitable for the device(s) in use.
Check that the minimum safety distances are used in accordance to draft EN999 contained within this
operation and installation manual. This is required for all installations going into the EC (European
Community).
Check that the pressure-sensitive mat or pressure-sensitive floor is fastened (fixed) securely in place
and does not provide a trip hazard.
Ensure that any "dead zones" do not provide an access path to the hazardous zone or area.
Check that the removal of the power supply from the pressure-sensitive mat or pressure-sensitive
floor prevents further operation of the machine. The machine should not be capable of being reactivated
until power has been restored and the reset operated.
Check that a hazardous movement or cycle is prevented while an actuating force is applied to the
effective sensing area.
Ensure that additional safeguards have been provided where necessary to prevent access to the
dangerous parts of machinery from any direction not protected by the pressure sensitive mat or pressure
sensitive floor.
Check that the presence of a person between the danger zone and the sensor is prevented. If this is
not possible, ensure that further safety measures are taken.
Check that all indicator lamps/lights are functioning correctly.
Check the sensitivity of the mat or floor over the whole effective sensing area.
The adequate safety required for a machine depends on the safety integrity of the interface between
the machine and its protective device(s). Where a category is stated by a "C" standard of a risk
assessment, the checks should ensure the machine control circuits and the connections to the safety
device(s) are in accordance with the interface connections agreed between the machine control
manufacturer and the safety protective device manufacturer. Always meet or exceed OSHA, ANSI, and
RIA safety standards.
Where muting is provided, ensure that muting occurs only during the intended part of the machines'
operation (e.g., during the cycle where no hazard exists). Refer to the applicable standard: OSHA CFR
1910.217, ANSI B11.1-2001, ANSI B11.19-2003, EN954-1, or the updated versions of these standards
for the application.
Do not release the subject machine for production unless all of the above items are met or exceeded.
