2 PTC AND OLP
Normal operation of
Compressor is
mposs b e or poor.
Separate the PTC-Starter
from Compressor and
measure the resistance
between No. 5 and 6 (only
RSIR type) or No. 4 and 5 of
PTC-Stader with a Tester or
Whistone Bridge.
(Figure 21)
Observation value is
220V/50Hz : 22§ _+30%
115V/60Hz : 6.8§ _+30%
240V/50Hz :33§ _+30%
127, 220V/60Hz : 22§
+_3O%

Separate the OLP from the
Compressor and check the
resistance value between
two terminals of OLP with
a Tester. (Figure 22)
