WARNING: There is a problem in the safety switch circuit if the LEDs are not lit as indicated or if, having removed a cover or guard equipped with switch, the machine can be started. DO NOT operate the machine in this condition! Call a qualified electrician to locate and repair the fault immediately. See “Inspection”, page 58.

With all covers and guards in place, turn the power disconnect switch to “I” (ON). Only the green “relay condition” LEDs on the amplifier should be lit. Turn power disconnect switch to “O” (OFF).

Remove or open one cover or guard equipped with switch. Turn power disconnect switch to “I” (ON). Only the red “relay condition” LEDs and the red “switch output” LEDs corresponding to the switch on the removed or open cover should be lit on the amplifier.

If LEDs are lit correctly, push the “I” (START) button. The safety switch circuit has been interrupted and machine should NOT start.

If the machine does start, that safety circuit has failed. Push the “O” (STOP) button, then disconnect and lock out power source.

Turn the power disconnect switch to “O” (OFF) and replace or close the cover or guard.

Individually remove or open each additional cover or guard equipped with switch and repeat steps 2 and 3. Make sure all covers and guards are securely in place after all switches have been tested.
