1.2 Pilot Maintenance Test
Connect the REL300 per Figure B-1, Configuration 1.
1.2.1 Basic Function Test
Step 1.
1.2.2 Input Opto-Coupler Check
The following test steps 2 and 3 are optional since the OPTO inputs PLT-ENA, RCVR-1 and
RCVR-2 have been checked in Section 1.1.4 (page B-11).
Step 2.
a. Block Systems Only
Change the STYP setting to BLK. 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 PLT ENA terminals TB 5/9(+) and TB 5/10(-). Repeat the test.
The relay should trip.
b. POTT/PUTT Systems Only
Change the STYP setting to POTT. Change the LED mode to TEST and select the func-
tion "RS1". Push the ENTER button; the LED should be "ON". Apply a forward fault as
shown in
relay should not trip. Apply a rated dc voltage to terminals TB 5/9(+) and TB 5/10(-). Re-
peat the test. The relay should trip.
Step 3.
a. Block Systems Only
Change the STYP setting to BLK. Apply a forward fault as shown in the Non-Pilot Mainte-
nance test, Step 5 (page B-1). The relay should trip.
B-4
Repeat Step 1 thru 8 in the Non-Pilot Maintenance Test, page B-1 (1.1.1 thru
1.1.5).
