Precautions
Changing Fluid Passage Condition / Piping Method
Illustrations showing changing of the fluid passage condition (left image: N.C. / right image: N.O.)
*Make sure that the pressure inside the valve is exhausted before changing the flow passage state.
Loosen the M4 ×; 0.7 hex socket head cap screw on the switch board and align the ▲ mark on the adapter plate with the required passage symbol (N.C./N.O.) on the switch plate. However, the X symbol cannot be used.
Moreover, follow the table on the right for piping.
Screw tightening torque M4: 1.4 N·m
Piping Method
| Passage | Port | ||
|---|---|---|---|
| P | A | R | |
| N.C. | Primary side | Secondary side | Exhaust side (Plug if using a 2 way valve) |
| N.O. | Exhaust side (Plug if using a 2 way valve) | Secondary side | Primary side |
*Use adequate caution and check it is safe when changing the fluid passage state or when starting up again afterwards.
Other
*The M5 hole on the left side of the adapter plate is the spool valve ventilation hole. Do not plug or obstruct it.
