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/GS-M, 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-M. As it is a non-safety function, this output is not used in safety-related control.
The terminal block and standard type are equipped with one AUX output for open/close link mode. The advanced function type is equipped with two AUX outputs for open/close link mode and lock link mode.

Lock Control Input

This input controls the locking function.

Lock control input
ON Connected to 24 V (PNP) or 0 V (NPN)	Locked
Off	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

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

Advanced function type	Light blue/black wire
Lock link mode	Open
Open/close link mode	Connected to 24 V

Terminal block/standard type	Gray wire
Lock link mode	Functions as AUX output
Open/close link mode	Connected to 24 V (PNP) or 0 V (NPN)
