SKILL 2 TEST A MANUAL SWITCH
B. If you are using the FaultPro Troubleshooting System, turn on the system.
C. Start up the FaultPro software and login using your ID number and
password.
D. If necessary, open the Class folder by clicking the
+
to the left of the class
name.
E. Open the
LAP 6: Introduction to Troubleshooting
option.
F. Select the
Skill 2: Test a Manual Switch
option.
G. Click the
Single Fault Mode
button.
The FaultPro software will open the Single Fault Mode window.
H. Type
6
in the Enter Fault fi eld.
I. Press the
Enter
key or click
to activate the fault.
Fault 6 is now active. You should observe that the fault status fi eld changes
from “No Faults Active” to “Fault 6 is Active.”
Fault 6 is a short in the N.O. contacts of PB1.
J. Repeat step 4 to test the pushbutton and record your measurements.
PB1 Resistance (not pressed) ___________________________ (Ohms)
PB1 Resistance (pressed) _______________________________ (Ohms)
Component Status _________________________________ (Good/Bad)
This time you should fi nd that the multimeter measures zero resistance
in both conditions. This means that there is a short in the contacts. The
component is bad.
K. Click the
Clear Fault
button to clear the fault or remove the fault plug.
With the FaultPro software, the fault will clear and the fault status fi eld
should change to “Fault 6 is cleared.”
If you are using manual fault insertion, remove the short plug from
terminal 6 and replace it with the standard jumper plug.
L. Repeat the pushbutton test in step 4.
PB1 Resistance (not pressed) ___________________________ (Ohms)
PB1 Resistance (pressed) ______________________________ (Ohms)
Component Status _________________________________ (Good/Bad)
The resistance should change this time when the pushbutton is pressed.
This means it is good again.
Now proceed to the next substep to test an open type fault in N.O. contacts.
M. If you are using manual fault insertion, locate the open fault plug and plug
it into station fault terminal 7. Then, go to substep P. If you are using the
FaultPro software, continue with substep N.
N. Type
7
to insert fault 7 in the Enter Fault fi eld.
