Part description

 Switch body 

Part description Switch body
No. Name Function
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□-□)
Actuator detection surface When the actuator is brought near to the surface, the switch body detects the actuator.
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.
