TESTING INSTRUCTIONS

 

Connect the switch to the ST-800, place a suitable target in front of the switch. If the switch is functioning correctly, the unit will give audio and visual indication showing the switch operates and indicating the functionality of the switch according to the chart below.

Switch type	Buzzer & LED on when	LED
PNP normally open	target in range	PNP
PNP normally closed	target not in range	PNP
NPN normally open	target in range	NPN
NPN normally closed	target not in range	NPN

If the proximity switch does not give such feedback when correctly connected to the tester, it has probably failed. [Note: The ST-800 will not test 2 wire AC or DC switches]
