REMEDY
(5)
Replace valve.
(9)
Check voltage. Replace pilot valve assem bly.
(6)
Replace pilot valve assem bly.
(7)
Adjust pressure so that pilot pressure will fall within operating pressure range during opretation.
(8)
-If worng oil used, com pletely air blow to rem ove oil and replace valve. After valve is replaced,
use turbine oil class 1 (ISO VG32).
No.
Remedy
(2)
Re-wire correctly.
(1)
Regulate voltage, so that the voltage at the tim e of the operationbecom es specifications range.
(3)
Replace part.
(4)
Replace part or re-wire positively.
-W hen a large quantity of drain is given and cannot carry out drain om ission surely, install
either an auto-drain or a dryer. The valve should be replaced.
