Figure 5-6. Target Indicator Test Setup

Manual Trip

1. Configure the relay for manual trip testing:

a. Connect the test setup as shown in Figure 5-4.

b. Set circuit board switch SW3 as follows:

SW3-1 = ON for 50 Hz operation or OFF for 60 Hz operation
SW3-2 = OFF (no additional time delay for the 50-A element)
SW3-3 = ON (GE IAC type characteristic curves)
SW3-4 = ON (integrating reset characteristic)

c. Set TIME DIAL to 0.0

d. Set CURVE to S.

e. Set TIME PICKUP to 0.2.

Set INST PICKUP (50-A) to 18.0.

g. Set INST PICKUP (50-B) (accessed at the top side of the assembly) at 20 (0.4 Aac).

2. Apply 0.18 Aac to terminals 5 and 6 (0.18 Aac provides relay operating power but is below the pickup

threshold.)

3. Connect a jumper to the Time Overcurrent Manual Trip jacks. Verify that the stop input of the test set

timer recognizes a 51 contact closure.

4. Remove the jumper and the current applied at relay terminals 5 and 6.

5. Apply 0.18 Aac to terminals 5 and 6.

6. Connect a jumper to the Instantaneous Overcurrent Manual Trip jacks. Verify that the stop input of

the test set timer recognizes a 50-A contact closure

7. Remove the jumper and the current applied to relay terminals 5 and 6.

8. Reset

targets.
