FEEDBACK SOLENOID VALVE RESISTANCE MEASURE-
MENT NuMIIGEh
(1) Using a circuit tester, check that there is no continuity
between the solenoid valve body and terminals.
(2) Measure resistance between the terminals.
Standard value : 54 - m (at ZO’C (66”F)]
BIMETAL ASSEMBLY RESISTANCE MEASUREMENT NI,M=~~
Using a circuit tester, measure resistance between the
terminal and body.
Standard value : Approx. 60 [at ZO’C(SVF]]
DASH POT INSPECTION
NWMGGA
Check that the dash pot operates normally. Resistance must
be felt when the dash pot rod is pulled. When the rod is
released, it must return quickly to the orignal position. If no
resistance is felt when it is pulled, the diaphragm or the check
valve is broken. If the rod returns slowly, the check valve is
binding. In either case, replace the dash pot.
DEPRESSION CHAMBER INSPECTiON
B14MGHAa
Check the depression chamber diaphragm for damage. First,
push up the rod fully and closing tightly the nipple with a
finger, release the rod. The diaphragm is intact if the rod does
not return to the initial position while the nipple is held closed
with a finger. If the rod returns. the diaphragm is broken. .~
Replace the depression chamber.
