Apply a rated dc voltage to RCVR #1 terminals TB 5/7 (+) and TB 5/8(-). Repeat the test.
The relay should not trip. Move the dc voltage from RCVR #1 to RCVR #2 terminals TB 5/
11(+) and TB 5/12(-), and repeat this test for RCVR #2.
b. POTT/PUTT Systems Only
Change the STYP setting to POTT. Apply a forward fault as shown in the Non-Pilot Main-
tenance test, Step 5. The relay should not trip. Apply a rated dc voltage to RCVR #1
terminals TB 5/7(+) and TB 5/8(-). Repeat the test. The relay should trip.
Move the dc voltage from RCVR #1 to RCVR #2 terminals TB 5/11(+) and TB 5/12(-), and
repeat this test for RCVR #2.
1.3
Single-Pole Trip Test
1.3.1
Output Contact Test (Phases B and C)
Step 1.
Step 2.
1.3.2
Input Opto-Coupler Check
The following test step 3 is optional since the OPTO input 52a has been checked in section
1.1.4 OPTO-Input Check.
Step 3.
Set relay according to Table B-1 (page B-11). Check the 62T setting; it should be
5.000.
For a Pilot system, change the PLT setting to YES, and apply rated dc voltage to
Pilot enable terminals TB 5/9(+) and TB 5/10(-). Also, apply a rated voltage to
RCVR #1 terminals TB 5/7(+) and TB 5/8(-) if the STYP = POTT or PUTT; set
TTYP = SPR.
Repeat Non-Pilot Maintenance test, step 5 for trip and BFI. Check the contact clo-
sures for Trip A, Trip B, Trip C and BFIA, BFIB, BFIC.
52a Terminals
Apply a rated voltage to 52b terminals TB 5/3(+) and TB 5/4(-) and then apply a
rated voltage to 52a terminals TB 5/1(+) and TB 5/2(-). The relay should trip in 5
seconds with a display of 62T.
