Wiring diagram

When using a DIN terminal (with light and surge voltage suppressor), internal wiring connections are as follows. These are respectively connected to the power supply side.

Handling when Changing Flow Path States

Example of handling when making changes to the flow path state

Example of handling when making changes to the flow path state

When changing the flow path state, check that there is no pressure within the valve.
On the function plate, loosen the hexagon socket head screw (M4 × 0.7) and align the 't' mark on the adapter plate to the letters on the switching plate. Perform porting as shown in the table below.

ExternalUniversal porting (The primary side can be ported anywhere.)

*1: When using with an internal pilot, check that a plug is inserted into the X port. If not, place an R plug.
*2: When using with an external pilot, apply pressure from the X port.

  • *Whenever you change the flow path state or restart after changing, do so with care and do a full safety check.
