Terminal DI1 / DI1: Safety contact (Normal close)
MODE 1 (Normally close, DC12 V) *When Bit1 of SW505 is OFF
• If this contact is open for more than 1 minute, the check code P10 is generated and the Dx-coil controller switches off
automatically.
MODE
2 (Normally open, DC12 V) *When Bit1 of SW505 is ON
• If this contact is short for more than 1 minute, the check code P10 is generated and the Dx-coil controller switches of
f
automatically.
SW701 SW505 Function

OFF
The coil drive voltage is input to the relay arranged locally for DI1, and judge that the close is
positive. (Default)
Relay: Local arrangement
ON
The coil drive voltage is not input to the relay arranged locally for DI1, and judge that the open is
positive.
Relay: Local arrangement

OFF
For DI1, short-circuit the (+) signal voltage and DI1 (-) GND with a SW or harness, and judge
that the close is positive.
Relay: Not required
* The signal voltage is DC12 V ± 10%, and it is necessary to add a SW element to the signal line.
ON
For DI1, open the (+) signal voltage and DI1 (-) GND, and judge that the open is positive.
Relay: Not required
* The signal voltage is DC12 V ± 10%, and it is necessary to add a SW element to the signal line.
