TEST SPECIAL RELAY ASSEMBLY (cont)
b. Test the dc relay assembly (8)
as follows:
(1)
Apply 24 Vdc to terminals
6 and 15 then use an
ohmmeter to test for con-
tinuity across terminals
5 and 17, and an open
circuit across terminals
4 and 17, and 3 and 13.
(2)
(3)
(4)
(5)
(6)
(7)
(8)
Remove the 24 Vdc from
terminals 6 and 15, and
apply the 24 Vdc to ter-
minals 13 and 15. Use the
ohm meter to test for con-
tinuity across terminals
1 and 14 and 2 and 3.
Remove the 24 Vdc from
terminals 13 and 15.
Place the ohmmeter probes
across terminals 10 and
12, and record the meter
indication.
Reverse the
probes on terminals 10
and 12, and record the
indication.
Resistances
indicated should be high
in one direction and low
in the other.
Repeat the above test,
using terminals 24 and 21.
Use the ohmmeter to test
resistance across termi-
nals 7 and 8 for approxi-
mately 7.5 K ohms resis-
tance.
Repeat step (6) to test
resistance across ter-
minals 19 and 20 for same
meter indications.
Apply 120 Vac to terminals
18 and 22 and use the ohm
meter to test resistance
across terminals 7 and 8,
and 19 and 20. Meter
