3.3 Bench test procedure
3.3.1 Type 33
Use StoneL Light Read Tester. Or use a 24 V DC or 120 V
AC power supply with series load resistor (2 kΩ - 6 kΩ).
3.3.2 Type X
Use StoneL Light Read Tester. Or use a 24 V DC or 120 V
AC power supply with series load resistor (2 kΩ - 6 kΩ).
3.3.3 Types E, F
Connect a load resistor of 3 kΩ to 10 kΩ across a
switch’s Load and (+) terminals (QN2E, QX2E), or a
switch’s Load and (-) terminals (QN2F, QX2F). Using a
24 V DC power source, connect the power source (+)
lead to a switch’s (+) terminal and the power source (-)
lead to a switch’s (-) terminal. Connect a voltmeter
across the load resistor. Apply 24 V DC. With cam acti-
vation strip in front of sensor target, the voltmeter will
read >20 V DC.
Activation strip away from sensor target voltmeter will
read 0 V DC.
Warning: Connecting the switch to a power source
without a load resistor may result in irreparable dam-
age to the switch.
3.3.4 Type 44
Use StoneL Light Read Tester or use a 24 V DC power
supply.
No series load resistor required.
3.3.5 Types A, N
Use StoneL Light Read Tester or use a 12 V DC power
supply and an ammeter.
No series load resistor required.
3.3.6 Types P, L, G, H, S
Test LED units with 9 volt battery and series load resis-
tor between 150 and 1000 Ω - 1/2 W. Ohm meter will not
work. (Light Read tester available from StoneL or
StoneL distributor.)
Minimum of 3.5 V required for proper switch operation.
3.3.7 Type 93
Use 9 to 32 V DC power supply across FB + and FB -.
No series resistor needed. To test communication, a
functioning Foundation Fieldbus network is required.
3.3.8 Types 96, 97
To Bench Test AS-Interface Module: Use 24 V DC
power supply across ASI + and ASI -. No series resistor
needed. To test communication, a functioning AS-Inter-
face network is required.
Do not apply external power to output terminals.
WARNING:
Failure to use a series load resistor when bench
testing sensors with a power supply will result in
permanent damage to the unit.
