Procedure for Switching the Channel
Switching the shield
When the connection method is selected, the shield wire is connected to the specified connection
destination.
Specified shield switching setting (shielding connection destination)
Module Connection method Shield connection destination
SW9001
2-wire TERMINAL 1 , LOW terminal
4-wire
GND
SW9002
2-wire TERMINAL 1 , LOW terminal
4-terminal pair TERMINAL 3 , sense shield terminal
The destination for shielding connection can be switched as necessary (for each slot).
Any time the connection method for a slot is changed, the switching shield will be reset to the
specified value. To set the switching shield to a value other than the specified value, be sure to set
the switching shield after setting the connection method.

For the SW9001, the [ TERMINAL 1 , LOW te TERMINAL 3 , sense shield terminal] shielding
connection destination terminal should only be used when connecting a BT3562, BT3562A series
(BT3562, BT3563, BT3561A, BT3562A, BT3563A) and DM7275 series (DM7275, DM7276) at the
same time when the DM7275/DM7276 contact check function is not operating properly.
Once the connection destination is specified, it is retained until the connection method is changed.
You do not have to specify the connection destination every time the channel is switched.
When the switching shield is set, all channels are set to open.
The source terminal for TERMINAL 2 and sense terminal are common for TERMINAL 3 .
