Instantaneous Pickup Test
1. Perform the following preliminary steps.
a. Connect test setup as shown in Figure 5-1.
b. Configure SW3 as follows: SW3-1 off for 60 Hz operation, on for 50 Hz operation, SW3-2
off, SW3-3 on, and SW3-4 on.
c. Set the time dial at 0.0.
d. Set the curve at S.
e. Set the time pickup at 1.0.
f.
Set the instantaneous pickup at 01.
2. Slowly increase the current applied to terminals 5 and 6. The instantaneous output contacts
should close at an input current of 0.955 to 1.045 Aac.
3. Decrease the input current until the instantaneous output contacts open.
4. Set the instantaneous pickup at 08.
5. Slowly increase the current applied to terminals 5 and 6. The instantaneous contacts should close
at an input current of 7.815 to 8.185 Aac.
6. Decrease the input current until the instantaneous output contacts open.
Time Dial Test
1. Perform the following preliminary steps.
a. Connect test setup as shown in Figure 5-1.
b. Configure SW3 as follows: SW3-1 off for 60 Hz operation, on for 50 Hz operation, SW3-2
off, SW3-3 on, and SW3-4 on.
c. Set the time dial at 4.5.
d. Set the curve at S.
e. Set the time pickup at 1.0.
f.
Set the instantaneous pickup at 90.
2. Prepare to apply 1.5 Aac to terminals 5 and 6 and record the elapsed time from when current is
applied until the time output contacts close.
3. Apply the current (step from 0 to 1.5 Aac) and record the elapsed time. The elapsed time should
be between 0.345 and 0.424 seconds. (This tolerance is greater than
±
2% because it is the
accumulation of both pickup and timing tolerances.)
4. Remove the input current.
Target Test
1. Perform the following preliminary steps.
a. Connect test setup as shown in Figure 5-2.
b. Configure SW3 as follows: SW3-1 off for 60 Hz operation, on for 50 Hz operation, SW3-2
off, SW3-3 on, and SW3-4 on.
c. Set the time dial at 4.5
d. Set the curve at S.
e. Set the time pickup at 1.0.
f.
Set the instantaneous pickup at 01.
2. Set the target current source at 1.0 Aac.
3. Apply 5 Aac to terminals 5 and 6. Verify that the Time and Instantaneous targets operate.
4. Remove the input current and reset the targets.
Manual Trip Test
1. Perform the following preliminary steps.
a. Connect test setup as shown in Figure 5-2.
b. Configure SW3 as follows: SW3-1 off for 60 Hz operation, on for 50 Hz operation, SW3-2
off, SW3-3 on, and SW3-4 on.
c. Set the time dial at 4.5
d. Set the curve at S.
e. Set the time pickup at 1.0.
f.
Set the instantaneous pickup at 01.
