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. |

② | 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 actuator to the door. The screws should be tightened with a torque of 1.2 N∙m. |
③ | Transmission part | The light of the indicator is transmitted through the part. |
About maintenance actuators (optional) |
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. |

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

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. |
