1. Connect and configure the relay for target indicator testing:
Target Indicators
a. Connect the test setup 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 1.0.
f. Set INST PICKUP (50-A) to 90.
g. Set INST PICKUP (50-B) (accessed at the top side of the assembly) to F0 (15.0 Aac).
The Target Operating Current Jumpers are located on the circuit board and identified as J1 and J2. J1
sets the minimum current range for the 50-A target and J2 sets the minimum current range for the 51
target. A jumper installed across pins 1 and 2 gives a minimum operating current of 0.9 to 2.25 A. A
jumper installed across pins 2 and 3 gives a minimum operating current of 80 to 200 mA.
2. Apply 2 Aac to terminals 5 and 6 to trip the 51 relay output.
3. Set voltage source to provide a target current determined by the target operating current jumpers.
4. Remove the target and sensing current and reset the target.
5. Set TIME PICKUP to 9.0.
6. Set INST PICKUP (50-A) to 01.
7. Apply 2 Aac to terminals 5 and 6 to trip the 50-A relay output.
8. Slowly increase the target current source and verify that the Instantaneous target operates at the
level of current determined by the Target Operating Current Jumpers.
9. Remove the target and sensing current and reset the targets.
