Wiring Explanation

OSSD

OSSD1 and OSSD2 form a pair of safety outputs that output the same status. The OSSD is connected to the safety-related control system.
It is wired to a force guided relay, magnet contactor, or safety controller.

Safety Input

This can be connected to the OSSD of another GS, allowing for cascading. Safety input 1 and safety input 2 form a pair of safety inputs.
When not using cascading, short-circuit to 24 V for the PNP type and to 0 V for the NPN type.

AUX Output

This is an information output used to check the operating status of the GS. As it is a non-safety function, this output is not used in safety-related control.
It monitors the open/closed and locked states (only on the locking type). For details, see the user’s manual.

Lock Control Input (Locking Type Only)

This input controls the locking function. The operation varies between the power-to-release and power-to-close functions.

Lock control input	Power-to-release	Power-to-lock
On	Unlocked	Locked
Off	Locked	Unlocked

Reset/EDM Input and Interlock/EDM Selection Input

This wiring determines whether the interlock and EDM functions are used. Operation is performed according to the combinations in the following table.

Interlock function	EDM function	Reset/EDM input (yellow)	Interlock/EDM function selection input (pink)
Automatic	Not used	Connected to 0 V	Connected to 0 V
Automatic	Used	Connected to 24 V via a relay NC contact	Open
Manual	Not used	Connected to 24 V via an NO reset switch	Connected to 24 V
Manual	Used	Connected to 24 V via an NO reset switch and a relay NC contact	Connected to 24 V

OSSD Operation Switching (GS-73P* Only)

The OSSD operation can be switched between lock link mode and open/close link mode via the wiring.

Lock link mode	Open	* Used as AUX output
Open/close link mode	Connected to 0 V	Connected to 24 V
