Safety Devices Functional Testing
It is necessary to test the functionality of the safety devices at regular time intervals. The safety
emergency stop function must be tested daily before each and every shift of operation. The
procedure for testing the emergency stop function is as follows:
1. Connect the machine to the main electrical power source.
2. De-press the emergency stop pushbutton on the main electrical enclosure.
3. Press the start pushbutton on the main enclosure. If the machine does not start proceed to
the next step. If the machine does start unplug it from the main electrical power source and
report it to your supervisor. This machine cannot be used until a qualified technician
corrects the issue.
4. Reset the estop pushbutton to its extended state. Push the start pushbutton the machine
should start. With the machine running de-press the emergency stop pushbutton, the
machine should now stop. This confirms that the emergency stop function is working
correctly.
5. Test all E-Stops on the machine separately.
The overload motor relay must be tested every three months to confirm its operation. This test can
only be performed by a qualify technician since it requires the enclosure door to be opened.
1. Connect the machine to the main electrical power source.
2. Insure that the emergency stop pushbutton is fully extended.
3. De-press the machine start pushbutton. The machine drive motor should start at this time.
4. Open the main electrical enclosure. Use extreme caution not to contact any live conductors.
5. Locate the overload relay and de-press the red test button on the front of the unit. The
machine should stop. If the machine does not stop the overloads relay is defective and needs
to be changed out. If the machine stops the overload relay passes the functionality test.
6. Install the main enclosure cover and secure all (4) screws.
Never operate a machine that does not pass the safety functional testing! Report it to management
and have the machine taken out of service until the deficiency is corrected.
