Part description

Switch body

No.	Name	Function
①	Indicator	Lights green	When the actuator is detected
		Lights red	When the actuator is not detected
		Blinks red	• Lockout state, error occurrence • When the teaching sequence was incorrect (only when using highcode models SG-P20□-□)
		Blinks green	When other switch bodies (standard unit, sub unit) in series connection do not detect actuators, when error occurs
		Lights yellow (Simultaneously light green and red) (Note)	After the power supply is turned ON, during self-diagnosis
		Alternately blinking red to yellow (lights red, blinking green) (Note)	When an unpaired actuator is detected (only when using highcode models SG-P20□-□)
②	Actuator detection surface	When the actuator is brought near to the surface, the switch body detects the actuator.
③	Mounting hole	Use M4 screws (length: 20 mm 0.787 in or more), flat washers and spring washers (not supplied with the product) to install the switch body to the equipment body or guard. The screws should be tightened with a torque of 1.2 N∙m.

Note :	When you look at a lit LED on a visible type model through the actuator, the LED may sometimes appear green in some part and red in other part.

About maintenance actuators (optional)

Using a maintenance actuator incorrectly can lead to an accident. Be sure to understand the operation of the system when using a maintenance actuator to use maintenance actuators correctly.

By directly mounting the maintenance actuator to the switch body while the door is open, it is possible to distinguish accidental opening of the door. Two types of maintenance actuators are available: overall maintenance type (SG-PK-M1) and individual maintenance type (SG-PK-M2 (Note)).
Note: In the case of the individual maintenance type SG-PK-M2, multiple units can be installed and used simultaneously.

Type	Overall maintenance type	Individual maintenance type
Model No.	SG-PK-M1	SG-PK-M2
Ambient temperature	0 to +40 ℃ 0 to +104 ℉ (No dew condensation), Storage: -25 to +65 ℃ -13 to +149 ℉
Ambient humidity	35 to 85 % RH, storage: 35 to 85 % RH
Vibration resistance	10 to 55Hz, 1 mm double amplitude, 2 hours each in X, Y, and Z directions
Shock resistance	300 m/s² (30 G approx.), 3 times each in X, Y, and Z direction
Material	POM (polyacetal)
Weight	7 g approx.

・ Overall maintenance type (SG-PK-M1) can be used only on standard switch bodies.

・ Individual maintenance type (SG-PK-M2) can be used on standard and sub switch bodies.

・ When maintenance actuators are used, redundant input monitoring (dual channel monitoring) of OSSD1and OSSD2 for the SG-P series by a safety controller, etc. cannot be used.

・ When using a maintenance actuator, be careful that the normal actuator will not be detected at the same time.

・ Determine whether to use the normal mode or maintenance mode according to the system.

Output operation and indicator operation

Operation differs between the overall maintenance type (SG‑PK‑M1) and individual maintenance type (SG‑PK‑M2). The output operation and indicator operation of the switch body when used with each maintenance actuator is as follows

When using overall maintenance type actuator (SG-PK-M1)
The SG-PK-M1 can only be used on standard switch bodies.

Note:	Individual maintenance type (SG-PK-M2) cannot be used when overall maintenance type is used.

Type		Standard			Sub1			Sub2			OSSD1	OSSD2
Type		Actuator	Detection Status	Indicator	Actuator	Detection Status	Indicator	Actuator	Detection Status	Indicator	OSSD1	OSSD2
Overall Mainte- nance		Mainte- nance	Detection	Yellow	Normal	Detection	Yellow	Normal	Detection	Yellow	ON	OFF
			Detection	Yellow		Detection	Yellow		Not detected	Red	ON	OFF
			Detection	Yellow		Not detected	Red		Detection	Yellow	ON	OFF
			Not detected	Red		Detection	Blinks green		Detection	Blinks green	OFF	OFF
	After 12 hours (Note 1)		Detection	Blinks yellow/ red		Detection	Blinks yellow/ red		Detection	Blinks yellow/ red	OFF	OFF

Notes:

1)	Maintenance actuator can operate continuously for up to 12 hours. After 12 hours, OSSD1 turns OFF automatically and the indicator on the switch body blinks in yellow / red. To use the maintenance actuator again, detach the actuator and reinstall.
2)	The indicator on the switch body blinks in yellow or red to indicate one of the two modes. For details, see the Instruction Manual of the SG-P series.

When using individual maintenance type actuator (SG-PK-M2)
The SG-PK-M2 can be used for standard and sub switch bodies.

Type		Standard			Sub1			Sub2			OSSD1	OSSD2
Type		Actuator	Detection Status	Indicator	Actuator	Detection Status	Indicator	Actuator	Detection Status	Indicator	OSSD1	OSSD2
Indi- vidual Mainte- nance		Normal	Detection	Yellow	Mainte- nance	Detection	Yellow	Normal	Detection	Yellow	OFF	ON
			Not detected	Red		Detection	Blinks yellow/ red		Detection	Blinks yellow/ red	OFF	OFF
			Detection	Blinks green		Not detected	Red		Detection	Blinks green	OFF	OFF
	After 12 hours (Note)		Detection	Blinks yellow/ red		Detection	Blinks yellow/ red		Detection	Blinks yellow/ red	OFF	OFF

Note :	Maintenance actuator can operate continuously for up to 12 hours. After 12 hours, OSSD2 turns OFF automatically and the indicator on the switch body blinks in yellow / red. To use the maintenance actuator again, detach the actuator and reinstall.
